This memo documents the process used by the Internet community for the standardization of protocols and procedures. It defines the stages in the standardization process, the requirements for moving a document between stages and the types of documents used during this process. It also addresses the intellectual property rights and copyright issues associated with the standards process.¶
This document obsoletes RFC2026, RFC5657, RFC6410, RFC7100, RFC7127, RFC7475, RFC8179, RFC8789, and RFC9282. It updates RFC5378, RFC5657. It also updated RFC7475, and with [bis2418], obsoletes it.¶
This note is to be removed before publishing as an RFC.¶

This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.¶
Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet-Drafts is at https://datatracker.ietf.org/drafts/current/.¶
Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."¶
This Internet-Draft will expire on 9 March 2025.¶

This document is subject to BCP 78 and the IETF Trust's Legal Provisions Relating to IETF Documents (https://trustee.ietf.org/license-info) in effect on the date of publication of this document. Please review these documents carefully, as they describe your rights and restrictions with respect to this document. Code Components extracted from this document must include Revised BSD License text as described in Section 4.e of the Trust Legal Provisions and are provided without warranty as described in the Revised BSD License.¶
NOTE: This document started with the raw text of RFC 2026. The plan is that each version of this Internet-Draft will incorporate one of the 10 RFCs that updated the original. Once all have been merged in, we will submit this to the GENDISPATCH working group to determine the next steps. Specifically, the RFCs to be incorporated are: RFC 5378, RFC 6410, RFC 7100, RFC 7127, RFC 7475, RFC 8179, RFC 8789, and RFC 9282. RFC 3667 was obsoleted by RFC 3978, which in turn was obsoleted by RFC 5378. RFC 3668 was obsoleted by RFC 3979, which in turn was obsoleted by RFC 8179. RFC 3932 was obsoleted by RFC 5742. RFC 3978 was obsoleted by RFC 8179. RFC 5657 became not relevant because of RFC 6410, which is also emphasized by RFC 7127. If this document gets adopted by a Working Group, the errata for all of the above-mentioned RFCs should be reviewed.¶
This memo documents the process currently used by the Internet community for the standardization of protocols and procedures. The Internet Standards process is an activity of the Internet Society (ISOC) that is organized and managed on behalf of the Internet community by the Internet Architecture Board (IAB) and the Internet Engineering Steering Group (IESG).¶
The Internet, a loosely-organized international collaboration of autonomous, interconnected networks, supports host-to-host communication through voluntary adherence to open protocols and procedures defined by Internet Standards. There are also many isolated interconnected networks, which are not connected to the global Internet but use the Internet Standards.¶
The Internet Standards Process described in this document is concerned with all protocols, procedures, and conventions that are used in or by the Internet, whether or not they are part of the TCP/IP protocol suite. In the case of protocols developed and/or standardized by non-Internet organizations, however, the Internet Standards Process normally applies to the application of the protocol or procedure in the Internet context, not to the specification of the protocol itself.¶
In general, an Internet Standard is a specification that is stable and well-understood, is technically competent, has multiple, independent, and interoperable implementations with substantial operational experience, enjoys significant public support, and is recognizably useful in some or all parts of the Internet.¶
The process described here only applies to the IETF RFC stream. See [RFC4844] for the definition of the streams and [RFC5742] for a description of the IESG responsibilities related to those streams.¶
Although this document is not an IETF Standards Track publication, it adopts the conventions for normative language to provide clarity of instructions to the implementer. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶
The following terms are used throughout this document. For more details about the organizations related to the IETF, see [RFC9281], Section 3.¶
The IAB Document Stream, the IRTF Document Stream, and the Independent Submission Stream, each as defined in [RFC8729], Section 5.1, along with any future non-IETF streams that might be defined.¶
The manager of an IETF Area.¶
Advanced Research Projects Agency; an agency of the US Department of Defense.¶
See Section 12.5.5.3.¶
Any submission to the IETF intended by the Contributor for publication as all or part of an Internet-Draft or RFC and any statement made within the context of an IETF activity, in each case that is intended to affect the IETF Standards Process or that is related to the activity of an Alternate Stream that has adopted this policy.¶
Such statements include oral statements, as well as written and electronic communications, which are addressed to:¶
Any IETF plenary session,¶
Any IETF Working Group (WG; see [BCP25]) or portion thereof or any WG chair on behalf of the relevant WG,¶
Any IETF "birds of a feather" (BOF) session or portion thereof,¶
WG design teams (see [BCP25]) and other design teams that intend to deliver an output to IETF, or portions thereof,¶
The IESG, or any member thereof on behalf of the IESG,¶
The IAB, or any member thereof on behalf of the IAB,¶
Any IETF mailing list, web site, chat room, or discussion board operated by or under the auspices of the IETF, including the IETF list itself,¶
The RFC Editor or the Internet-Drafts function.¶
Statements made outside of an IETF session, mailing list, or other function, or that are clearly not intended to be input to an IETF activity, group, or function, are not Contributions in the context of this document. And while the IETF's IPR rules apply in all cases, not all presentations represent a Contribution. For example, many invited plenary, area-meeting, or research group presentations will cover useful background material, such as general discussions of existing Internet technology and products, and will not be a Contribution. (Some such presentations can represent a Contribution as well, of course). Throughout this document, the term "written Contribution" is used. For purposes of this document, "written" means reduced to a written or visual form in any language and any media, permanent or temporary, including but not limited to traditional documents, email messages, discussion board postings, slide presentations, text messages, instant messages, and transcriptions of oral statements.¶
An individual submitting a Contribution.¶
The legal right granted to an author in a document or other work of authorship under applicable law. A "copyright" is not equivalent to a "right to copy". Rather a copyright encompasses all of the exclusive rights that an author has in a work, such as the rights to copy, publish, distribute and create derivative works of the work. An author often cedes these rights to his or her employer or other parties as a condition of employment or compensation.¶
A valid claim of a patent or a patent application (including a provisional patent application) in any jurisdiction, or any other Intellectual Property Right, would necessarily be infringed by the exercise of a right (e.g., making, using, selling, importing, distribution, copying, etc.) with respect to an Implementing Technology. For purposes of this definition, "valid claim" means a claim of any unexpired patent or patent application which shall not have been withdrawn, cancelled, or disclaimed, nor held invalid by a court of competent jurisdiction in an unappealed or unappealable decision.¶
See Section 12.5.9.¶
In the context of this document, the IETF includes all individuals who participate in meetings, working groups, mailing lists, functions, and other activities that are organized or initiated by ISOC, the IESG, or the IAB under the general designation of the Internet Engineering Task Force (IETF), but solely to the extent of such participation.¶
A management division within the IETF. An Area consists of Working Groups related to a general topic such as routing. An Area is managed by one or more Area Directors.¶
RFCs and Internet-Drafts that are published as part of the IETF Standards Process. These are also referred to as "IETF Stream Documents" as defined in [RFC8729], Section 5.1.1.¶
The activities undertaken by the IETF in any of the settings described in the above definition of Contribution. The IETF Standards Process may include participation in activities and publication of documents that are not directed toward the development of IETF standards or specifications, such as the development and publication of Informational and Experimental documents (see Section 6).¶
A trust established under the laws of the Commonwealth of Virginia, USA, in order to hold and administer intellectual property rights for the benefit of the IETF.¶
A technology that implements an IETF specification or standard.¶
Any person who has materially or substantially contributed to a Contribution without being personally involved in its submission to the IETF.¶
A document used in the IETF and RFC Editor processes, as described in Section 4.¶
A group comprised of the IETF Area Directors and the IETF Chair. The IESG is responsible for the management, along with the IAB, of the IETF and is the standards approval board for the IETF.¶
For the purposes of this document, "interoperable" means to be able to interoperate over a data communications path.¶
Means a patent, utility model, or similar right that may Cover an Implementing Technology, whether such rights arise from a registration or renewal thereof, or an application therefore, in each case anywhere in the world. See Section 12.4.1.4 for a discussion of trademarks.¶
A public comment period used to gauge the level of consensus about the reasonableness of a proposed standards action. See Section 8.1.2.¶
The standardized text that is maintained by the IETF Trust and is included in IETF Documents and the instructions and requirements for including that standardized text in IETF Documents. The text and instructions are posted from time to time at the Trust Legal Provisions¶
Making a Contribution, as described above, or in any other way acting in order to influence the outcome of a discussion relating to the IETF Standards Process. Without limiting the generality of the foregoing, acting as a Working Group Chair or Area Director constitutes "Participating" in all activities of the relevant working group(s) he or she is responsible for in an area. "Participant" and "IETF Participant" mean any individual Participating in an IETF discussion or activity.¶
The basic publication series for the IETF.¶
Something an individual knows personally or, because of the job the individual holds, would reasonably be expected to know. This wording is used to indicate that an organization cannot purposely keep an individual in the dark about patents or patent applications just to avoid the disclosure requirement. But this requirement should not be interpreted as requiring the IETF Contributor or Participant (or his or her represented organization, if any) to perform a patent search to find applicable IPR.¶
A group chartered by the IESG and IAB to work on a specific specification, set of specifications or topic.¶
In outline, the process of creating an Internet Standard is straightforward: a specification undergoes a period of development and several iterations of review by the Internet community and revision based upon experience, is adopted as a Standard by the appropriate body (see below), and is published. In practice, the process is more complicated, due to (1) the difficulty of creating specifications of high technical quality; (2) the need to consider the interests of all of the affected parties; (3) the importance of establishing widespread community consensus; and (4) the difficulty of evaluating the utility of a particular specification for the Internet community.¶
The goals of the Internet Standards Process are:¶
Technical excellence;¶
Prior implementation and testing;¶
Clear, concise, and easily-understood documentation;¶
Openness and fairness; and¶
Timeliness¶
The procedures described in this document are designed to be fair, open, and objective; to reflect existing (proven) practice; and to be flexible.¶
These procedures are intended to provide a fair, open, and objective basis for developing, evaluating, and adopting Internet Standards. They provide ample opportunity for participation and comment by all interested parties. At each stage of the standardization process, a specification is repeatedly discussed and its merits debated in open meetings and/or public electronic mailing lists, and it is made available for review via world-wide on-line directories.¶
These procedures are explicitly aimed at recognizing and adopting generally-accepted practices. Thus, a candidate specification must be implemented and tested for correct operation and interoperability by multiple independent parties and utilized in increasingly demanding environments, before it can be adopted as an Internet Standard.¶
These procedures provide a great deal of flexibility to adapt to the wide variety of circumstances that occur in the standardization process. Experience has shown this flexibility to be vital in achieving the goals listed above.¶
The goal of technical competence, the requirement for prior implementation and testing, and the need to allow all interested parties to comment all require significant time and effort. On the other hand, today's rapid development of networking technology demands timely development of standards. The Internet Standards Process is intended to balance these conflicting goals. The process is believed to be as short and simple as possible without sacrificing technical excellence, thorough testing before adoption of a standard, or openness and fairness.¶
From its inception, the Internet has been, and is expected to remain, an evolving system whose participants regularly factor new requirements and technology into its design and implementation. Users of the Internet and providers of the equipment, software, and services that support it should anticipate and embrace this evolution as a major tenet of Internet philosophy.¶
The procedures described in this document are the result of a number of years of evolution, driven both by the needs of the growing and increasingly diverse Internet community, and by experience.¶
Section 4 describes the publications and archives of the Internet Standards Process. Section 5 describes the types of Internet standard specifications. Section 6 describes the Internet standards specifications track. Section 7 describes Best Current Practice RFCs. Section 8 describes the process and rules for Internet standardization. Section 9 specifies the way in which externally- sponsored specifications and practices, developed and controlled by other standards bodies or by others, are handled within the Internet Standards Process. Section 10 describes the requirements for notices and record keeping Section 11 defines a variance process to allow one-time exceptions to some of the requirements in this document Section 12 presents the rules that are required to protect intellectual property rights in the context of the development and use of Internet Standards.¶
Each distinct version of an Internet standards-related specification is published as part of the "Request for Comments" (RFC) document series. This archival series is the official publication channel for Internet standards documents and other publications of the IESG, IAB, and the Internet community. RFCs can be obtained from a number of Interenet hosts using standard Internet applications such as the WWW.¶
The RFC series of documents on networking began in 1969 as part of the original ARPA wide-area networking (ARPANET) project. RFCs cover a wide range of topics in addition to Internet Standards, from early discussion of new research concepts to status memos about the Internet. For information about RFC publication, see [RFC9280].¶
The rules for formatting and submitting an RFC are defined in [RFC7322]. Every RFC is available in ASCII text. Some RFCs are also available in other formats. The other versions of an RFC may contain material (such as diagrams and figures) that is not present in the ASCII version, and it may be formatted differently.¶
A stricter requirement applies to standards-track
specifications: the ASCII text version is the
definitive reference, and therefore it must be a
complete and accurate specification of the standard,
including all necessary diagrams and illustrations.
¶
Some RFCs document Internet Standards. These RFCs form the 'STD' subseries of the RFC series [RFC1311]. When a specification has been adopted as an Internet Standard, it is given the additional label "STDxxx", but it keeps its RFC number and its place in the RFC series (see Section 6.1.2). The status of Internet protocol and service specifications is available from the RFC Index in the RFC repository.¶
Some RFCs standardize the results of community deliberations about statements of principle or conclusions about what is the best way to perform some operations or IETF process function. These RFCs form the specification has been adopted as a BCP, it is given the additional label "BCPxxx", but it keeps its RFC number and its place in the RFC series. (see Section 7)¶
Not all specifications of protocols or services for the Internet should or will become Internet Standards or BCPs. Such non-standards track specifications are not subject to the rules for Internet standardization. Non-standards track specifications may be published directly as "Experimental" or "Informational" RFCs at the discretion of the RFC Editor in consultation with the IESG (see Section 6.2).¶
It is important to remember that not all RFCs
are standards track documents, and that not all
standards track documents reach the level of
Internet Standard. In the same way, not all RFCs
which describe current practices have been given
the review and approval to become BCPs. See
{{!RFC1796} for further information.
¶
During the development of a specification, draft versions of the document are made available for informal review and comment by placing them in the IETF's "Internet-Drafts" directory, which is replicated on a number of Internet hosts. This makes an evolving working document readily available to a wide audience, facilitating the process of review and revision.¶
An Internet-Draft that is published as an RFC, or that has remained unchanged in the Internet-Drafts directory for more than six months without being recommended by the IESG for publication as an RFC, is simply removed from the Internet-Drafts directory. At any time, an Internet-Draft may be replaced by a more recent version of the same specification, restarting the six-month timeout period.¶
An Internet-Draft is NOT a means of "publishing" a specification; specifications are published through the RFC mechanism described in the previous section. Internet-Drafts have no formal status, and are subject to change or removal at any time.¶
Under no circumstances should an Internet-Draft
be referenced by any paper, report, or Request-
for-Proposal, nor should a vendor claim compliance
with an Internet-Draft.
¶
Note: It is acceptable to reference a standards-track specification that may reasonably be expected to be published as an RFC using the phrase "Work in Progress" without referencing an Internet-Draft. This may also be done in a standards track document itself as long as the specification in which the reference is made would stand as a complete and understandable document with or without the reference to the "Work in Progress".¶
Specifications subject to the Internet Standards Process fall into one of two categories: Technical Specification (TS) and Applicability Statement (AS).¶
A Technical Specification is any description of a protocol, service, procedure, convention, or format. It may completely describe all of the relevant aspects of its subject, or it may leave one or more parameters or options unspecified. A TS may be completely self- contained, or it may incorporate material from other specifications by reference to other documents (which might or might not be Internet Standards).¶
A TS shall include a statement of its scope and the general intent for its use (domain of applicability). Thus, a TS that is inherently specific to a particular context shall contain a statement to that effect. However, a TS does not specify requirements for its use within the Internet; these requirements, which depend on the particular context in which the TS is incorporated by different system configurations, are defined by an Applicability Statement.¶
An Applicability Statement specifies how, and under what circumstances, one or more TSs may be applied to support a particular Internet capability. An AS may specify uses for TSs that are not Internet Standards, as discussed in Section 9.¶
An AS identifies the relevant TSs and the specific way in which they are to be combined, and may also specify particular values or ranges of TS parameters or subfunctions of a TS protocol that must be implemented. An AS also specifies the circumstances in which the use of a particular TS is required, recommended, or elective (see Section 5.3).¶
An AS may describe particular methods of using a TS in a restricted "domain of applicability", such as Internet routers, terminal servers, Internet systems that interface to Ethernets, or datagram- based database servers.¶
The broadest type of AS is a comprehensive conformance specification, commonly called a "requirements document", for a particular class of Internet systems, such as Internet routers or Internet hosts.¶
An AS may not have a higher maturity level in the standards track than any standards-track TS on which the AS relies (see Section 6.1).¶
An AS shall apply one of the following "requirement levels" to each of the TSs to which it refers:¶
Required: Implementation of the referenced TS, as specified by the AS, is required to achieve minimal conformance. For example, IP and the Internet Control Message Protocl (ICMP) must be implemented by all Internet systems using the TCP/IP Protocol Suite.¶
Recommended: Implementation of the referenced TS is not required for minimal conformance, but experience and/or generally accepted technical wisdom suggest its desirability in the domain of applicability of the AS. Vendors are strongly encouraged to include the functions, features, and protocols of Recommended TSs in their products, and should omit them only if the omission is justified by some special circumstance. For example, the TELNET protocol should be implemented by all systems that would benefit from remote access.¶
Elective: Implementation of the referenced TS is optional within the domain of applicability of the AS; that is, the AS creates no explicit necessity to apply the TS. However, a particular vendor may decide to implement it, or a particular user may decide that it is a necessity in a specific environment.¶
As noted in Section 6.1, there are TSs that are not in the standards track or that have been retired from the standards track, and are therefore not required, recommended, or elective. Two additional "requirement level" designations are available for these TSs:¶
Limited Use: The TS is considered to be appropriate for use only in limited or unique circumstances. For example, the usage of a protocol with the "Experimental" designation should generally be limited to those actively involved with the experiment.¶
Not Recommended: A TS that is considered to be inappropriate for general use is labeled "Not Recommended". This may be because of its limited functionality, specialized nature, or historic status.¶
Although TSs and ASs are conceptually separate, in practice a standards-track document may combine an AS and one or more related TSs. For example, Technical Specifications that are developed specifically and exclusively for some particular domain of applicability, e.g., for mail server hosts, often contain within a single specification all of the relevant AS and TS information. In such cases, no useful purpose would be served by deliberately distributing the information among several documents just to preserve the formal AS/TS distinction. However, a TS that is likely to apply to more than one domain of applicability should be developed in a modular fashion, to facilitate its incorporation by multiple ASs.¶
Specifications that are intended to become Internet Standards evolve through a set of maturity levels known as the "standards track". These maturity levels -- "Proposed Standard" and "Internet Standard" -- are defined and discussed in Section 6.1. The way in which specifications move along the standards track is described in Section 8.¶
Even after a specification has been adopted as an Internet Standard, further evolution often occurs based on experience and the recognition of new requirements. The nomenclature and procedures of Internet standardization provide for the replacement of old Internet Standards with new ones, and the assignment of descriptive labels to indicate the status of "retired" Internet Standards. A set of maturity levels is defined in Section 6.2 to cover these and other specifications that are not considered to be on the standards track.¶
Internet specifications go through stages of development, testing, and acceptance. Within the Internet Standards Process, these stages are formally labeled "maturity levels".¶
This section describes the maturity levels and the expected characteristics of specifications at each level.¶
The entry-level maturity for the standards track is "Proposed Standard". A specific action by the IESG is required to move a specification onto the standards track at the "Proposed Standard" level.¶
A Proposed Standard specification is stable, has resolved known design choices, has received significant community review, and appears to enjoy enough community interest to be considered valuable.¶
Usually, neither implementation nor operational experience is required for the designation of a specification as a Proposed Standard. However, such experience is highly desirable and will usually represent a strong argument in favor of a Proposed Standard designation.¶
The IESG may require implementation and/or operational experience prior to granting Proposed Standard status to a specification that materially affects the core Internet protocols or that specifies behavior that may have significant operational impact on the Internet.¶
A Proposed Standard will have no known technical omissions with respect to the requirements placed upon it. Proposed Standards are of such quality that implementations can be deployed in the Internet. However, as with all technical specifications, Proposed Standards may be revised if problems are found or better solutions are identified, when experiences with deploying implementations of such technologies at scale is gathered.¶
Notwithstanding the previous paragraph, the IETF may occasionally choose to publish as Proposed Standard a document that contains areas of known limitations or challenges. In such cases, any known issues with the document will be clearly and prominently communicated in the document, for example, in the abstract, the introduction, or a separate section or statement.¶
A specification for which significant implementation and successful operational experience has been obtained may be elevated to the Internet Standard level. An Internet Standard is characterized by a high degree of technical maturity and by a generally held belief that the specified protocol or service provides significant benefit to the Internet community.¶
A specification that reaches the status of Internet Standard is assigned a number in the STD series while retaining its RFC number.¶
Not every specification is on the standards track. A specification may not be intended to be an Internet Standard, or it may be intended for eventual standardization but not yet ready to enter the standards track. A specification may have been superseded by a more recent Internet Standard, or have otherwise fallen into disuse or disfavor.¶
Specifications that are not on the standards track are labeled with one of three "off-track" maturity levels: "Experimental", "Informational", or "Historic". The documents bearing these labels are not Internet Standards in any sense.¶
The "Experimental" designation typically denotes a specification that is part of some research or development effort. Such a specification is published for the general information of the Internet technical community and as an archival record of the work, subject only to editorial considerations and to verification that there has been adequate coordination with the standards process (see below). An Experimental specification may be the output of an organized Internet research effort (e.g., a Research Group of the Internet Research Task Force) an IETF Working Group, or it may be an individual contribution.¶
An "Informational" specification is published for the general information of the Internet community, and does not represent an Internet community consensus or recommendation. The Informational designation is intended to provide for the timely publication of a very broad range of responsible informational documents from many sources, subject only to editorial considerations and to verification that there has been adequate coordination with the standards process (see Section 6.2.3).¶
Specifications that have been prepared outside of the Internet community and are not incorporated into the Internet Standards Process by any of the provisions of Section 12 may be published as Informational RFCs, with the permission of the owner and the concurrence of the RFC Editor.¶
Unless they are the result of IETF Working Group action, documents intended to be published with Experimental or Informational status should be submitted directly to the RFC Editor. The RFC Editor will publish any such documents as Internet-Drafts which have not already been so published. In order to differentiate these Internet-Drafts they will be labeled or grouped in the I-D directory so they are easily recognizable. The RFC Editor will wait two weeks after this publication for comments before proceeding further. The RFC Editor is expected to exercise his or her judgment concerning the editorial suitability of a document for publication with Experimental or Informational status, and may refuse to publish a document which, in the expert opinion of the RFC Editor, is unrelated to Internet activity or falls below the technical and/or editorial standard for RFCs.¶
To ensure that the non-standards track Experimental and Informational designations are not misused to circumvent the Internet Standards Process, the IESG and the RFC Editor have agreed that the RFC Editor will refer to the IESG any document submitted for Experimental or Informational publication which, in the opinion of the RFC Editor, may be related to work being done, or expected to be done, within the IETF community. The IESG shall review such a referred document within a reasonable period of time, and recommend either that it be published as originally submitted or referred to the IETF as a contribution to the Internet Standards Process.¶
If (a) the IESG recommends that the document be brought within the IETF and progressed within the IETF context, but the author declines to do so, or (b) the IESG considers that the document proposes something that conflicts with, or is actually inimical to, an established IETF effort, the document may still be published as an Experimental or Informational RFC. In these cases, however, the IESG may insert appropriate "disclaimer" text into the RFC either in or immediately following the "Status of this Memo" section in order to make the circumstances of its publication clear to readers.¶
Documents proposed for Experimental and Informational RFCs by IETF Working Groups go through IESG review. The review is initiated using the process described in Section 8.1.1.¶
A specification that has been superseded by a more recent specification or is for any other reason considered to be obsolete is assigned to the "Historic" level. (Purists have suggested that the word should be "Historical"; however, at this point the use of "Historic" is historical.)¶
Note: Standards track specifications normally must not depend on other standards track specifications which are at a lower maturity level or on non standards track specifications other than referenced specifications from other standards bodies. (See Section 9.)¶
The BCP subseries of the RFC series is designed to be a way to standardize practices and the results of community deliberations. A BCP document is subject to the same basic set of procedures as standards track documents and thus is a vehicle by which the IETF community can define and ratify the community's best current thinking on a statement of principle or on what is believed to be the best way to perform some operations or IETF process function.¶
Historically Internet standards have generally been concerned with the technical specifications for hardware and software required for computer communication across interconnected networks. However, since the Internet itself is composed of networks operated by a great variety of organizations, with diverse goals and rules, good user service requires that the operators and administrators of the Internet follow some common guidelines for policies and operations. While these guidelines are generally different in scope and style from protocol standards, their establishment needs a similar process for consensus building.¶
While it is recognized that entities such as the IAB and IESG are composed of individuals who may participate, as individuals, in the technical work of the IETF, it is also recognized that the entities themselves have an existence as leaders in the community. As leaders in the Internet technical community, these entities should have an outlet to propose ideas to stimulate work in a particular area, to raise the community's sensitivity to a certain issue, to make a statement of architectural principle, or to communicate their thoughts on other matters. The BCP subseries creates a smoothly structured way for these management entities to insert proposals into the consensus-building machinery of the IETF while gauging the community's view of that issue.¶
Finally, the BCP series may be used to document the operation of the IETF itself. For example, this document defines the IETF Standards Process and is published as a BCP.¶
Unlike standards-track documents, the mechanisms described in BCPs are not well suited to the phased roll-in nature of the three stage standards track and instead generally only make sense for full and immediate instantiation.¶
The BCP process is similar to that for proposed standards. The BCP is submitted to the IESG for review, (see Section 8.1.1) and the existing review process applies, including a Last-Call on the IETF Announce mailing list. However, once the IESG has approved the document, the process ends and the document is published. The resulting document is viewed as having the technical approval of the IETF.¶
Specifically, a document to be considered for the status of BCP must undergo the procedures outlined in Section 8.1, and Section 8.4 of this document. The BCP process may be appealed according to the procedures in Section 8.5.¶
Because BCPs are meant to express community consensus but are arrived at more quickly than standards, BCPs require particular care. Specifically, BCPs should not be viewed simply as stronger Informational RFCs, but rather should be viewed as documents suitable for a content different from Informational RFCs.¶
A specification, or group of specifications, that has, or have been approved as a BCP is assigned a number in the BCP series while retaining its RFC number(s).¶
The mechanics of the Internet Standards Process involve decisions of the IESG concerning the elevation of a specification onto the standards track or the movement of a standards-track specification from one maturity level to another. Although a number of reasonably objective criteria (described below and in Section 6) are available to guide the IESG in making a decision to move a specification onto, along, or off the standards track, there is no algorithmic guarantee of elevation to or progression along the standards track for any specification. The experienced collective judgment of the IESG concerning the technical quality of a specification proposed for elevation to or advancement in the standards track is an essential component of the decision-making process.¶
A "standards action" -- entering a particular specification into, advancing it within, or removing it from, the standards track -- must be approved by the IESG.¶
A specification that is intended to enter or advance in the Internet standards track shall first be posted as an Internet-Draft (see Section 4.2) unless it has not changed since publication as an RFC. It shall remain as an Internet-Draft for a period of time, not less than two weeks, that permits useful community review, after which a recommendation for action may be initiated.¶
A standards action is initiated by a recommendation by the IETF Working group responsible for a specification to its Area Director, copied to the IETF Secretariat or, in the case of a specification not associated with a Working Group, a recommendation by an individual to the IESG.¶
For classification as an Internet Standard, the request for reclassification must include an explanation of how the following criteria have been met:¶
There are at least two independent interoperating implementations with widespread deployment and successful operational experience. Although not required by the IETF Standards Process, [RFC5657] can be helpful to conduct interoperability testing.¶
There are no errata against the specification that would cause a new implementation to fail to interoperate with deployed ones.¶
There are no unused features in the specification that greatly increase implementation complexity.¶
If the technology required to implement the specification requires patented or otherwise controlled technology, then the set of implementations must demonstrate at least two independent, separate and successful uses of the licensing process.¶
The IESG shall determine whether or not a specification submitted to it according to Section 8.1.1 satisfies the applicable criteria for the recommended action (see Section 6.1 and Section 6.2), and shall in addition determine whether or not the technical quality and clarity of the specification is consistent with that expected for the maturity level to which the specification is recommended.¶
The IESG is not bound by the action recommended when the specification was submitted. For example, the IESG may decide to consider the specification for publication in a different category than that requested. If the IESG determines this before the Last- Call is issued then the Last-Call should reflect the IESG's view. The IESG could also decide to change the publication category based on the response to a Last-Call. If this decision would result in a specification being published at a "higher" level than the original Last-Call was for, a new Last-Call should be issued indicating the IESG recommendation. In addition, the IESG may decide to recommend the formation of a new Working Group in the case of significant controversy in response to a Last-Call for specification not originating from an IETF Working Group.¶
In order to obtain all of the information necessary to make these determinations, particularly when the specification is considered by the IESG to be extremely important in terms of its potential impact on the Internet or on the suite of Internet protocols, the IESG may, at its discretion, commission an independent technical review of the specification.¶
The IESG will send notice to the IETF of the pending IESG consideration of the document(s) to permit a final review by the general Internet community. This "Last-Call" notification shall be via electronic mail to the IETF Announce mailing list. Comments on a Last-Call shall be accepted from anyone, and should be sent as directed in the Last-Call announcement.¶
For a Proposed Standard, the Last-Call period shall be no shorter than two weeks except in those cases where the proposed standards action was not initiated by an IETF Working Group, in which case the Last-Call period shall be no shorter than four weeks. If the IESG believes that the community interest would be served by allowing more time for comment, it may decide on a longer Last-Call period or to explicitly lengthen a current Last-Call period.¶
For an Internet Standard, the IESG will perform a review and consideration of any errata that have been filed. If they do not believe any of these should hold up the advancement, then the IESG, in an IETF-wide Last Call of at least four weeks, informs the community of their intent to advance a document from Proposed Standard to Internet Standard.¶
If there is consensus for reclassification, the RFC will be reclassified without publication of a new RFC.¶
In a timely fashion after the expiration of the Last-Call period, the IESG shall make its final determination of whether or not to approve the standards action, and shall notify the IETF of its decision via electronic mail to the IETF Announce mailing list.¶
In no event shall a document be published on the IETF Stream without IETF consensus.¶
If a standards action is approved, notification is sent to the RFC Editor and copied to the IETF with instructions to publish the specification as an RFC. The specification shall at that point be removed from the Internet-Drafts directory.¶
The procedure described in Section 8.1 is followed for each action that attends the advancement of a specification along the standards track.¶
A specification shall remain at the Proposed Standard level for at least six months. This minimum period is intended to ensure adequate opportunity for community review without severely impacting timeliness. The interval shall be measured from the date of publication of the corresponding RFC(s), or, if the action does not result in RFC publication, the date of the announcement of the IESG approval of the action.¶
A specification may be (indeed, is likely to be) revised as it advances through the standards track. At each stage, the IESG shall determine the scope and significance of the revision to the specification, and, if necessary and appropriate, modify the recommended action. Minor revisions are expected, but a significant revision may require that the specification accumulate more experience at its current maturity level before progressing. Finally, if the specification has been changed very significantly, the IESG may recommend that the revision be treated as a new document, re- entering the standards track at the beginning.¶
Change of status shall result in republication of the specification as an RFC, except in the rare case that there have been no changes at all in the specification since the last publication. Generally, desired changes will be "batched" for incorporation at the next level in the standards track. However, deferral of changes to the next standards action on the specification will not always be possible or desirable; for example, an important typographical error, or a technical error that does not represent a change in overall function of the specification, may need to be corrected immediately. In such cases, the IESG or RFC Editor may be asked to republish the RFC (with a new number) with corrections, and this will not reset the minimum time-at-level clock.¶
A new version of an established Internet Standard must progress through the full Internet standardization process as if it were a completely new specification. Once the new version has reached the Standard level, it will usually replace the previous version, which will be moved to Historic status. However, in some cases both versions may remain as Internet Standards to honor the requirements of an installed base. In this situation, the relationship between the previous and the new versions must be explicitly stated in the text of the new version or in another appropriate document (e.g., an Applicability Statement; see Section 5.2).¶
As the technology changes and matures, it is possible for a new Standard specification to be so clearly superior technically that one or more existing standards track specifications for the same function should be retired. In this case, or when it is felt for some other reason that an existing standards track specification should be retired, the IESG shall approve a change of status of the old specification(s) to Historic. This recommendation shall be issued with the same Last-Call and notification procedures used for any other standards action. A request to retire an existing standard can originate from a Working Group, an Area Director or some other interested party.¶
Disputes are possible at various stages during the IETF process. As much as possible the process is designed so that compromises can be made, and genuine consensus achieved, however there are times when even the most reasonable and knowledgeable people are unable to agree. To achieve the goals of openness and fairness, such conflicts must be resolved by a process of open review and discussion. This section specifies the procedures that shall be followed to deal with Internet standards issues that cannot be resolved through the normal processes whereby IETF Working Groups and other Internet Standards Process participants ordinarily reach consensus.¶
An individual (whether a participant in the relevant Working Group or not) may disagree with a Working Group recommendation based on his or her belief that either (a) his or her own views have not been adequately considered by the Working Group, or (b) the Working Group has made an incorrect technical choice which places the quality and/or integrity of the Working Group's product(s) in significant jeopardy. The first issue is a difficulty with Working Group process; the latter is an assertion of technical error. These two types of disagreement are quite different, but both are handled by the same process of review.¶
A person who disagrees with a Working Group recommendation shall always first discuss the matter with the Working Group's chair(s), who may involve other members of the Working Group (or the Working Group as a whole) in the discussion.¶
If the disagreement cannot be resolved in this way, any of the parties involved may bring it to the attention of the Area Director(s) for the area in which the Working Group is chartered. The Area Director(s) shall attempt to resolve the dispute.¶
If the disagreement cannot be resolved by the Area Director(s) any of the parties involved may then appeal to the IESG as a whole. The IESG shall then review the situation and attempt to resolve it in a manner of its own choosing.¶
If the disagreement is not resolved to the satisfaction of the parties at the IESG level, any of the parties involved may appeal the decision to the IAB. The IAB shall then review the situation and attempt to resolve it in a manner of its own choosing.¶
The IAB decision is final with respect to the question of whether or not the Internet standards procedures have been followed and with respect to all questions of technical merit.¶
This document sets forward procedures required to be followed to ensure openness and fairness of the Internet Standards Process, and the technical viability of the standards created. The IESG is the principal agent of the IETF for this purpose, and it is the IESG that is charged with ensuring that the required procedures have been followed, and that any necessary prerequisites to a standards action have been met.¶
If an individual should disagree with an action taken by the IESG in this process, that person should first discuss the issue with the ISEG Chair. If the IESG Chair is unable to satisfy the complainant then the IESG as a whole should re-examine the action taken, along with input from the complainant, and determine whether any further action is needed. The IESG shall issue a report on its review of the complaint to the IETF.¶
Should the complainant not be satisfied with the outcome of the IESG review, an appeal may be lodged to the IAB. The IAB shall then review the situation and attempt to resolve it in a manner of its own choosing and report to the IETF on the outcome of its review.¶
If circumstances warrant, the IAB may direct that an IESG decision be annulled, and the situation shall then be as it was before the IESG decision was taken. The IAB may also recommend an action to the IESG, or make such other recommendations as it deems fit. The IAB may not, however, pre-empt the role of the IESG by issuing a decision which only the IESG is empowered to make.¶
The IAB decision is final with respect to the question of whether or not the Internet standards procedures have been followed.¶
Further recourse is available only in cases in which the procedures themselves (i.e., the procedures described in this document) are claimed to be inadequate or insufficient to the protection of the rights of all parties in a fair and open Internet Standards Process. Claims on this basis may be made to the ISOC Board of Trustees. The President of the ISOC shall acknowledge such an appeal within two weeks, and shall at the time of acknowledgment advise the petitioner of the expected duration of the Trustees' review of the appeal. The Trustees shall review the situation in a manner of its own choosing and report to the IETF on the outcome of its review.¶
The Trustees' decision upon completion of their review shall be final with respect to all aspects of the dispute.¶
All appeals must include a detailed and specific description of the facts of the dispute.¶
All appeals must be initiated within two months of the public knowledge of the action or decision to be challenged.¶
At all stages of the appeals process, the individuals or bodies responsible for making the decisions have the discretion to define the specific procedures they will follow in the process of making their decision.¶
In all cases a decision concerning the disposition of the dispute, and the communication of that decision to the parties involved, must be accomplished within a reasonable period of time.¶
NOTE: These procedures intentionally and explicitly do not establish a fixed maximum time period that shall be considered "reasonable" in all cases. The Internet Standards Process places a premium on consensus and efforts to achieve it, and deliberately foregoes deterministically swift execution of procedures in favor of a latitude within which more genuine technical agreements may be reached.¶
Many standards groups other than the IETF create and publish standards documents for network protocols and services. When these external specifications play an important role in the Internet, it is desirable to reach common agreements on their usage -- i.e., to establish Internet Standards relating to these external specifications.¶
There are two categories of external specifications:¶
Open Standards: Various national and international standards bodies, such as ANSI, ISO, IEEE, and ITU-T, develop a variety of protocol and service specifications that are similar to Technical Specifications defined here. National and international groups also publish "implementors' agreements" that are analogous to Applicability Statements, capturing a body of implementation-specific detail concerned with the practical application of their standards. All of these are considered to be "open external standards" for the purposes of the Internet Standards Process.¶
Other Specifications: Other proprietary specifications that have come to be widely used in the Internet may be treated by the Internet community as if they were a "standards". Such a specification is not generally developed in an open fashion, is typically proprietary, and is controlled by the vendor, vendors, or organization that produced it.¶
To avoid conflict between competing versions of a specification, the Internet community will not standardize a specification that is simply an "Internet version" of an existing external specification unless an explicit cooperative arrangement to do so has been made. However, there are several ways in which an external specification that is important for the operation and/or evolution of the Internet may be adopted for Internet use.¶
An Internet Standard TS or AS may incorporate an open external standard by reference. For example, many Internet Standards incorporate by reference the ANSI standard character set "US-ASCII" [US-ASCII]. Whenever possible, the referenced specification shall be available without restriction or undue fee using standard Internet applications such as the WWW.¶
Other proprietary specifications may be incorporated by reference to a version of the specification as long as the proprietor meets the requirements of Section 12. If the other proprietary specification is not widely and readily available, the IESG may request that it be published as an Informational RFC.¶
The IESG generally should not favor a particular proprietary specification over technically equivalent and competing specification(s) by making any incorporated vendor specification "required" or "recommended".¶
An IETF Working Group may start from an external specification and develop it into an Internet specification. This is acceptable if (1) the specification is provided to the Working Group in compliance with the requirements of Section 12, and (2) change control has been conveyed to IETF by the original developer of the specification for the specification or for specifications derived from the original specification.¶
Each of the organizations involved in the development and approval of Internet Standards shall publicly announce, and shall maintain a publicly accessible record of, every activity in which it engages, to the extent that the activity represents the prosecution of any part of the Internet Standards Process. For purposes of this section, the organizations involved in the development and approval of Internet Standards includes the IETF, the IESG, the IAB, all IETF Working Groups, and the Internet Society Board of Trustees.¶
For IETF and Working Group meetings announcements shall be made by electronic mail to the IETF Announce mailing list and shall be made sufficiently far in advance of the activity to permit all interested parties to effectively participate. The announcement shall contain (or provide pointers to) all of the information that is necessary to support the participation of any interested individual. In the case of a meeting, for example, the announcement shall include an agenda that specifies the standards- related issues that will be discussed.¶
The formal record of an organization's standards-related activity shall include at least the following:¶
The charter of the organization (or a defining document equivalent to a charter);¶
Complete and accurate minutes of meetings;¶
The archives of Working Group electronic mail mailing lists; and¶
All written contributions from participants that pertain to the organization's standards-related activity.¶
As a practical matter, the formal record of all Internet Standards Process activities is maintained by the IETF Secretariat, and is the responsibility of the IETF Secretariat except that each IETF Working Group is expected to maintain their own email list archive and must make a best effort to ensure that all traffic is captured and included in the archives. Also, the Working Group chair is responsible for providing the IETF Secretariat with complete and accurate minutes of all Working Group meetings. Internet-Drafts that have been removed (for any reason) from the Internet-Drafts directories shall be archived by the IETF Secretariat for the sole purpose of preserving an historical record of Internet standards activity and thus are not retrievable except in special circumstances.¶
This document, which sets out the rules and procedures by which Internet Standards and related documents are made is itself a product of the Internet Standards Process (as a BCP, as described in Section 7.) It replaces a previous version, and in time, is likely itself to be replaced.¶
While, when published, this document represents the community's view of the proper and correct process to follow, and requirements to be met, to allow for the best possible Internet Standards and BCPs, it cannot be assumed that this will always remain the case. From time to time there may be a desire to update it, by replacing it with a new version. Updating this document uses the same open procedures as are used for any other BCP.¶
In addition, there may be situations where following the procedures leads to a deadlock about a specific specification, or there may be situations where the procedures provide no guidance. In these cases it may be appropriate to invoke the variance procedure described below.¶
Upon the recommendation of the responsible IETF Working Group (or, if no Working Group is constituted, upon the recommendation of an ad hoc committee), the IESG may enter a particular specification into, or advance it within, the standards track even though some of the requirements of this document have not or will not be met. The IESG may approve such a variance, however, only if it first determines that the likely benefits to the Internet community are likely to outweigh any costs to the Internet community that result from noncompliance with the requirements in this document. In exercising this discretion, the IESG shall at least consider (a) the technical merit of the specification, (b) the possibility of achieving the goals of the Internet Standards Process without granting a variance, (c) alternatives to the granting of a variance, (d) the collateral and precedential effects of granting a variance, and (e) the IESG's ability to craft a variance that is as narrow as possible. In determining whether to approve a variance, the IESG has discretion to limit the scope of the variance to particular parts of this document and to impose such additional restrictions or limitations as it determines appropriate to protect the interests of the Internet community.¶
The proposed variance must detail the problem perceived, explain the precise provision of this document which is causing the need for a variance, and the results of the IESG's considerations including consideration of points (a) through (d) in the previous paragraph. The proposed variance shall be issued as an Internet Draft. The IESG shall then issue an extended Last-Call, of no less than 4 weeks, to allow for community comment upon the proposal.¶
In a timely fashion after the expiration of the Last-Call period, the IESG shall make its final determination of whether or not to approve the proposed variance, and shall notify the IETF of its decision via electronic mail to the IETF Announce mailing list. If the variance is approved it shall be forwarded to the RFC Editor with a request that it be published as a BCP.¶
This variance procedure is for use when a one-time waving of some provision of this document is felt to be required. Permanent changes to this document shall be accomplished through the normal BCP process.¶
The appeals process in Section 8.5 applies to this process.¶
No use of this procedure may lower any specified delays, nor exempt any proposal from the requirements of openness, fairness, or consensus, nor from the need to keep proper records of the meetings and mailing list discussions.¶
Specifically, the following sections of this document must not be subject of a variance: Section 7.1, Section 8.1, Section 8.1.1 (first paragraph), Section 8.1.2, Section 8.3 (first sentence), Section 8.5 and Section 11.¶
This section is not intended as legal advice. Readers are advised to consult their own legal advisors if they would like a legal interpretation of their rights or the rights of the IETF Trust [RFC8714] in any Contributions they make.¶
The IETF policies about Intellectual Property Rights (IPR), such as patent rights, relative to technologies developed in the IETF are designed to ensure that IETF working groups and Participants have as much information as possible about any IPR constraints on a technical proposal as early as possible in the development process. The policies are intended to benefit the Internet community and the public at large, while respecting the legitimate rights of IPR holders. This document details the IETF policies concerning IPR related to technology worked on within the IETF. It also describes the objectives that the policies are designed to meet.¶
There are three basic principles regarding how the IETF deals with claims of Intellectual Property Rights:¶
The IETF will make no determination about the validity of any particular IPR claim.¶
The IETF, following normal processes, can decide to use technology for which IPR disclosures have been made if it decides that such a use is warranted.¶
In order for a working group and the rest of the IETF to have the information needed to make an informed decision about the use of a particular technology, all those contributing to the working group's discussions must disclose the existence of any IPR the Contributor or any other IETF Participant believes Covers or may ultimately Cover the technology under discussion. This applies to both Contributors and other Participants, and applies whether they contribute in person, via email, or by other means. The requirement applies to all IPR of the Participant, the Participant's employer, sponsor, or others represented by the Participant that are reasonably and personally known to the Participant. No patent search is required.¶
In all matters relating to Intellectual Property Rights, the intent is to benefit the Internet community and the public at large, while respecting the legitimate rights of others. The disclosures required by this policy are intended to help IETF working groups define superior technical solutions with the benefit of as much information as reasonably possible about potential IPR claims relating to technologies under consideration.¶
By submission of a Contribution, each person actually submitting the Contribution, and each named co-Contributor, is deemed to agree to the following terms and conditions on his or her own behalf and on behalf of the organizations the Contributor represents or is sponsored by (if any) when submitting the Contribution.¶
By Participating in the IETF, each Participant is deemed to agree to comply with all requirements of this RFC that relate to Participation in IETF activities. Without limiting the foregoing, each Participant that is a Contributor makes the following representations to the IETF:¶
Such Contributor represents that he or she has made or will promptly make all disclosures required by Section 12.5.2.1 of this document.¶
Such Contributor represents that there are no limits to the Contributor's ability to make the grants, acknowledgments, and agreements herein that are reasonably and personally known to the Contributor.¶
This document has been developed for the benefit and use of the IETF community. As such, the rules set forth herein apply to all Contributions and IETF Documents that are in the "IETF Document Stream" as defined in [RFC8729], Section 5.1.1 (i.e., those that are contributed, developed, edited, and published as part of the IETF Standards Process).¶
The rules that apply to documents in Alternate Streams are established by the managers of those Alternate Streams (currently the Internet Architecture Board (IAB), Internet Research Steering Group (IRSG), and Independent Submission Editor, as specified in [RFC8729]). These managers may elect, through their own internal processes, to cause this document to be applied to documents contributed to them for development, editing, and publication in their respective Alternate Streams. If an Alternate Stream manager elects to adopt this document, they must do so in a manner that is public and notifies their respective document Contributors that this document applies to their respective Alternate Streams. In such case, each occurrence of the term "Contribution" and "IETF Document" in this document shall be read to mean a contribution or document in such Alternate Stream, as the case may be. It would be advisable for such Alternate Stream managers to consider adapting the definitions of "Contribution" and other provisions in this document to suit their¶
In all matters of copyright and document procedures, the intent is to benefit the Internet community and the public at large, while respecting the legitimate rights of others.¶
Under the laws of most countries and current international treaties (for example the "Berne Convention for the Protection of Literary and Artistic Work" [BERNE]), authors obtain numerous rights in the works they produce automatically upon producing them. These rights include copyrights, moral rights, and other rights. In many cases, if the author produces a work within the scope of his or her employment, most of those rights are usually assigned to the employer, either by operation of law or, in many cases, under contract. (The Berne Convention names some rights as "inalienable", which means that the author retains them in all cases.)¶
In order for Contributions to be used within the IETF Standards Process, including when they are published as Internet-Drafts or RFCs, certain limited rights must be granted to the IETF Trust, which then grants the necessary rights to the IETF. In addition, Contributors must make representations to the IETF Trust and the IETF regarding their ability to grant these rights.¶
The IETF Trust and the IETF must obtain the right to publish an IETF Contribution as an RFC or an Internet-Draft from the Contributors.¶
A primary objective of this policy is to obtain from the document authors only the non-exclusive rights that are needed to develop and publish IETF Documents and to use IETF Contributions in the IETF Standards Process and potentially elsewhere.¶
The authors retain all other rights, but cannot withdraw the above rights from the IETF Trust and the IETF.¶
It is important to note that under this document, Contributors are required to grant certain rights to the IETF Trust (see Section 12.4.2.3), which holds all IETF-related intellectual property on behalf of the IETF community. The IETF Trust will, in turn, grant a sublicense of these rights to all IETF participants for use in the IETF Standards Process (see Section 5.4.). This sublicense is necessary for the standards development work of the IETF to continue. In addition, the IETF Trust may grant certain other sublicenses of the rights that it is granted under this document. In granting such other sublicenses, the IETF Trust will be guided and bound by documents such as [RFC5377].¶
It is important that the IETF receive assurances from all Contributors that they have the authority to grant the IETF the rights that they claim to grant because, under the laws of most countries and applicable international treaties, copyright rights come into existence when a work of authorship is created (but see Section 12.4.1.5 regarding public domain documents), and the IETF cannot make use of IETF Contributions if it does not have sufficient rights with respect to these copyright rights. The IETF and its participants would run a greater risk of liability to the owners of these rights without this assurance. To this end, the IETF asks Contributors to give the assurances in Section 12.4.2.6. These assurances are requested, however, only to the extent of the Contributor's reasonable and personal knowledge as defined above.¶
The IETF needs to be able to evolve IETF Documents in response to experience gained in the deployment of the technologies described in such IETF Documents, to incorporate developments in research, and to react to changing conditions on the Internet and other IP networks. The IETF may also decide to permit others to develop derivative works based on Contributions. In order to do this, the IETF must be able to produce derivatives of its documents; thus, the IETF must obtain the right from Contributors to produce derivative works. Note that the right to produce translations is required before any Contribution can be published as an RFC, to ensure the widest possible distribution of the material in RFCs. The right to produce derivative works, in addition to translations, is required for all IETF Standards Track documents and for most IETF non-Standards Track documents. There are two exceptions to this requirement: documents describing proprietary technologies and documents that are republications of the work of other standards organizations.¶
The right to produce derivative works must be granted in order for an IETF working group to accept a Contribution as a working group document or otherwise work on it. For non-working group Contributions where the Contributor requests publication as a Standards Track RFC, the right to produce derivative works must be granted before the IESG will issue an IETF Last Call and, for most non-Standards Track, non-working group Contributions, before the IESG will consider the Internet-Draft for publication. Occasionally a Contributor may not want to grant publication rights or the right to produce derivative works before finding out if a Contribution has been accepted for development in the IETF Standards Process. In these cases, the Contributor may include a limitation on the right to make derivative works in the form specified in the Legend Instructions. A working group can discuss the Contribution with the aim to decide if it should become a working group document, even though the right to produce derivative works or to publish the Contribution as an RFC has not yet been granted. However, if the Contribution is accepted for development, the Contributor must resubmit the Contribution without the limitation notices before a working group can formally adopt the Contribution as a working group document. The IETF Trust may establish different policies for granting sublicenses with respect to different types of Contributions and content within Contributions (such as executable code versus descriptive text or references to third-party materials). The IETF Trust's policies concerning the granting of sublicenses to make derivative works will be guided by [RFC5377].¶
The IETF has historically encouraged organizations to publish details of their technologies, even when the technologies are proprietary, because understanding how existing technology is being used helps when developing new technology. But organizations that publish information about proprietary technologies are frequently not willing to have the IETF produce revisions of the technologies and then possibly claim that the IETF version is the "new version" of the organization's technology. Organizations that feel this way can specify that a Contribution be published with the other rights granted under this document but may withhold the right to produce derivative works other than translations.¶
In addition, IETF Documents frequently make normative references to standards or recommendations developed by other standards organizations. Since the publications of some standards organizations are not public documents, it can be quite helpful to the IETF to republish, with the permission of the other standards organization, some of these documents as RFCs so that the IETF community can have open access to them to better understand what they are referring to. In these cases, the RFCs can be published without the right for the IETF to produce derivative works. In both of the above cases, in which the production of derivative works is excluded, the Contributor must include a special legend in the Contribution, as specified in the Legend Instructions, in order to notify IETF participants about this restriction.¶
Contributors may wish to seek trademark or service mark protection on any terms that are coined or used in their Contributions. The IETF makes no judgment about the validity of any such trademark rights. However, the IETF requires each Contributor, under the licenses described in Section 12.4.2.3 below, to grant the IETF Trust a perpetual license to use any such trademarks or service marks solely in exercising rights to reproduce, publish, discuss, and modify the IETF Contribution. This license does not authorize the IETF or others to use any trademark or service mark in connection with any product or service offering.¶
Certain documents, including those produced by the U.S. government and those which are in the public domain, may not be protected by the same copyright and other legal rights as other documents. Nevertheless, we ask each Contributor to grant to the IETF the same rights he or she would grant, and to make the same representations, as though the IETF Contribution were protected by the same legal rights as other documents, and as though the Contributor could be able to grant these rights. We ask for these grants and representations only to the extent that the Contribution may be protected. We believe they are necessary to protect the ISOC, the IETF Trust, the IETF, the IETF Standards Process, and all IETF participants, and because the IETF does not have the resources or wherewithal to make any independent investigation as to the actual proprietary status of any document submitted to it.¶
As noted above, Contributors to the IETF (or their employers) retain ownership of the copyright in their Contributions. This includes Internet-Drafts and all other Contributions made within the IETF Standards Process (e.g., via e-mail, oral comment, and otherwise). However, it is important that the IETF (through the IETF Trust) own the copyright in documents that are published as RFCs (other than Informational RFCs and RFCs that are submitted as RFC Editor Contributions). Ownership of the copyright in an RFC does not diminish the Contributors' rights in their underlying contributions, but it does prevent anyone other than the IETF Trust (and its licensees) from republishing or modifying an RFC in RFC format. In this respect, Contributors are treated the same as anybody else: though they may extract and republish their own Contributions without limitation, they may not do so in the RFC format used by the IETF. And while this principle (which is included in Section 12.4.2.9 below) may appear to be new to the IETF, it actually reflects historical practice and has been observed for many years through the inclusion of an ISOC or IETF Trust copyright notice on all RFC documents since the publication of [RFC2026].¶
By submission of a Contribution, each person actually submitting the Contribution and each named co-Contributor is deemed to have read and understood the rules and requirements set forth in this document. Each Contributor is deemed, by the act of submitting a Contribution, to enter into a legally-binding agreement to comply with the terms and conditions set forth in this document.¶
The Contributor is further deemed to have agreed that he/she has obtained the necessary permissions to enter into such an agreement from any party that the Contributor reasonably and personally knows may have rights in the Contribution, including, but not limited to, the Contributor's sponsor or employer.¶
No further acknowledgment, signature, or other action is required to bind a Contributor to these terms and conditions. The operation of the IETF and the work conducted by its many participants is dependent on such agreement by each Contributor, and each IETF participant expressly relies on the agreement of each Contributor to the terms and conditions set forth in this document.¶
No information or document that is subject to any requirement of confidentiality or any restriction on its dissemination may be submitted as a Contribution or otherwise considered in any part of the IETF Standards Process, and there must be no assumption of any confidentiality obligation with respect to any Contribution. Each Contributor agrees that any statement in a Contribution, whether generated automatically or otherwise, that states or implies that the Contribution is confidential or subject to any privilege, can be disregarded for all purposes, and will be of no force or effect.¶
To the extent that a Contribution or any portion thereof is protected by copyright or other rights of authorship, the Contributor and each named co-Contributor grant a perpetual, irrevocable, non-exclusive, royalty-free, world-wide, sublicensable right and license to the IETF Trust under all such copyrights and other rights in the Contribution:¶
To copy, publish, display, and distribute the Contribution, in whole or in part,¶
To prepare translations of the Contribution into languages other than English, in whole or in part, and to copy, publish, display, and distribute such translations or portions thereof,¶
To modify or prepare derivative works (in addition to translations) that are based on or incorporate all or part of the Contribution, and to copy, publish, display, and distribute such derivative works, or portions thereof unless explicitly disallowed in the notices contained in a Contribution (in the form specified by the Legend Instructions), and¶
To reproduce any trademarks, service marks, or trade names which are included in the Contribution solely in connection with the reproduction, distribution, or publication of the Contribution and derivative works thereof as permitted by this section, provided that when reproducing Contributions, trademark and service mark identifiers used in the Contribution, including TM and (R), will be preserved.¶
The IETF Trust will sublicense the rights granted to it under Section 12.4.2.3 to all IETF participants for use within the IETF Standards Process. This license is expressly granted under a license agreement issued by the IETF Trust, which can be found at Trust Legal Provisions.¶
This license is expressly granted under a license agreement issued by the IETF Trust and must contain a pointer to the full IETF Trust agreement.¶
In addition, the IETF Trust may grant additional sublicenses of the licenses granted to it hereunder. In doing so, the IETF Trust will comply with the guidance provided under [RFC5377].¶
The licenses granted in Section 12.4.2.3 shall not be deemed to grant any right under any patent, patent application, or other similar intellectual property right disclosed by the Contributor under Section 12 or otherwise.¶
With respect to each Contribution, each Contributor represents that, to the best of his or her knowledge and ability:¶
The Contribution properly acknowledges all Contributors, including Indirect Contributors.¶
No information in the Contribution is confidential, and the IETF, IETF Trust, ISOC, and its affiliated organizations may freely disclose any information in the Contribution.¶
There are no limits to the Contributor's ability to make the grants, acknowledgments, and agreements herein that are reasonably and personally known to the Contributor.¶
The Contributor has not intentionally included in the Contribution any material that is defamatory or untrue or which is illegal under the laws of the jurisdiction in which the Contributor has his or her principal place of business or residence.¶
All trademarks, trade names, service marks, and other proprietary names used in the Contribution that are reasonably and personally known to the Contributor are clearly designated as such where reasonable.¶
The Contributor, and each named co-Contributor, acknowledges that the IETF has no duty to publish or otherwise use or disseminate any Contribution. The IETF reserves the right to withdraw or cease using any Contribution that does not comply with the requirements of this section.¶
Contributors who claim trademark rights in terms used in their IETF Contributions are requested to state specifically what conditions apply to implementers of the technology relative to the use of such trademarks. Such statements should be submitted in the same way as is done for other intellectual property claims. (See Section 7.)¶
Subject to each Contributor's (or its sponsor's) ownership of its underlying Contributions as described in Section 12.4.2.6 (which ownership is qualified by the irrevocable licenses granted under Section 12.4.2.3), each Contributor hereby acknowledges that the copyright in any RFC in which such Contribution is included, other than an RFC that is an RFC Editor Contribution, shall be owned by the IETF Trust. Such Contributor shall be deemed to assign to the IETF Trust such Contributor's copyright interest in the collective work constituting such RFC upon the submission of such RFC for publication, and acknowledges that a copyright notice acknowledging the IETF Trust's ownership of the copyright in such RFC will be included in the published RFC.¶
Although Contributors provide specific rights to the IETF, it is not intended that this should deprive them of their right to exploit their Contributions. To underscore this principle, the IETF Trust is directed to issue a license or assurance to Contributors, which confirms that they may each make use of their Contributions as published in an RFC in any way they wish, subject only to the restriction that no Contributor has the right to represent any document as an RFC, or equivalent of an RFC, if it is not a full and complete copy or translation of the published RFC.¶
The IETF requires that certain standardized text be reproduced verbatim in certain IETF Documents (including copies, derivative works, and translations of IETF Documents). Some of this standardized text may be mandatory (e.g., copyright notices and disclaimers that must be included in all RFCs) and some may be optional (e.g., limitations on the right to make derivative works). The text itself, as well as the rules that explain when and how it must be used, is contained in the Legend Instructions. The Legend Instructions may be updated from time to time, and the version of the standardized text that must be included in IETF Documents is that which was posted in the Legend Instructions on the date of publication.¶
The IETF reserves the right to refuse to publish Contributions that do not include the legends and notices required by the Legend Instructions.¶
It is important to note that each Contributor grants the IETF Trust rights pursuant to this document and the policies described herein. The legends and notices included in certain written Contributions such as Internet-Drafts do not themselves convey any rights. They are simply included to inform the reader (whether or not part of the IETF) about certain legal rights and limitations associated with such documents.¶
It is also important to note that additional copyright notices are not permitted in IETF Documents except in the case where such document is the product of a joint development effort between the IETF and another standards development organization or is a republication of the work of another standards development organization. Such exceptions must be approved on an individual basis by the IAB.¶
This document refers to the IETF Participant making disclosures, consistent with the general IETF philosophy that Participants in the IETF act as individuals. A Participant's obligation to make a disclosure is also considered satisfied if the IPR owner, which may be the Participant's employer or sponsor, makes an appropriate disclosure in place of the Participant doing so.¶
The IESG, IAB, ISOC, and IETF Trust disclaim any responsibility for identifying the existence of or for evaluating the applicability of any IPR, disclosed or otherwise, to any IETF technology, specification, or standard, and will take no position on the validity or scope of any such IPR.¶
When the IETF Secretariat has received a notification under Section 12.5.2.3 of the existence of non-participant IPR that potentially Covers a technology under discussion at IETF or which is the subject of an IETF Document, the IETF Secretariat shall promptly publish such notification and will request that the identified third party make an IPR disclosure in accordance with the provisions of Section 12.5.¶
When an IPR disclosure has been made as provided in Section 12.5 of this document, the IETF Secretariat may request from the purported holder of such IPR a written assurance that upon approval by the IESG for publication of the relevant IETF specification(s) as one or more RFCs, all persons will be able to obtain the right to implement, use, distribute, and exercise other rights with respect to Implementing Technology under one of the licensing options specified in Section 12.5.6 item 1 below unless a statement identifying one of the licensing options described in Section 12.5.6 item 1 has already been received by the IETF Secretariat. The working group proposing the use of the technology with respect to which the Intellectual Property Rights are disclosed may assist the IETF Secretariat in this effort. The results of this procedure shall not, in themselves, block publication of an IETF Document or advancement of an IETF Document along the Standards Track. A working group may take into consideration the results of this procedure in evaluating the technology, and the IESG may defer approval when a delay may facilitate obtaining such assurances. The results will, however, be recorded by the IETF Secretariat and be made available online.¶
The IESG will not make any determination that any terms for the use of an Implementing Technology (e.g., the assurance of reasonable and non-discriminatory terms) have been fulfilled in practice. It will instead apply the normal requirements for the advancement of Internet Standards (see Section 2). If the two unrelated implementations of the specification that are required to advance from Proposed Standard to Internet Standard have been produced by different organizations or individuals, or if the "significant implementation and successful operational experience" required to advance from Proposed Standard to Internet Standard has been achieved, the IESG will presume that the terms are reasonable and to some degree non-discriminatory. Note that this also applies to the case where multiple implementers have concluded that no licensing is required. This presumption may be challenged at any time, including during the Last Call period by sending email to the IESG.¶
Any Contributor who reasonably and personally knows of IPR meeting the conditions of Section 12.5.7 which the Contributor believes Covers or may ultimately Cover his or her written Contribution that is intended to be used as an input into the IETF Standards Process, or which the Contributor reasonably and personally knows his or her employer or sponsor may assert against Implementing Technologies based on such written Contribution, must make a disclosure in accordance with Section 12.5.¶
If an individual's Participation relates to a written Contribution made by somebody else that is intended to be used as an input into the IETF Standards Process, and such Participant reasonably and personally knows of IPR meeting the conditions of Section 12.5.7 which the Participant believes Covers or may ultimately Cover that Contribution, or which the Participant reasonably and personally knows his or her employer or sponsor may assert against Implementing Technologies based on such written Contribution, then such Participant must make a disclosure in accordance with Section 12.5.¶
If any person has information about IPR that may Cover a technology relevant to the IETF Standards Process, but such person is not required to disclose such IPR under Section 12.5.2.1 or Section 12.5.2.2 above, such person is nevertheless encouraged to file an IPR disclosure as described in Section 12.5.4 below. Such an IPR disclosure should be filed as soon as reasonably possible after the person realizes that such IPR may Cover a Contribution. Situations in which such voluntary IPR disclosures may be made include when (a) IPR does not meet the criteria in Section 12.5.7 because it is not owned or controlled by an IETF Participant or his or her sponsor or employer (referred to as third party IPR), (b) an individual is not required to disclose IPR meeting the requirements of Section 12.5.7 because that individual is not Participating in the relevant IETF activity, or (c) the IPR Covers technology that does not yet meet the criteria for a Contribution hereunder (e.g., it is disclosed in an informal or other non-IETF setting).¶
Timely IPR disclosure is important because working groups need to have as much information as they can while they are evaluating alternative solutions.¶
The IPR disclosure required pursuant to Section 12.5.2.1 must be made as soon as reasonably possible after the Contribution is submitted or made unless the required disclosure is already on file. See Section 12.5.5.2 for a discussion of when updates need to be made for an existing disclosure.¶
If a Contributor first learns of IPR in its Contribution that meets the conditions of Section 12.5.7, for example a new patent application or the discovery of a relevant patent in a patent portfolio, after the Contribution is published in an Internet- Draft, a disclosure must be made as soon as reasonably possible after the IPR becomes reasonably and personally known to the Contributor.¶
The IPR disclosure required pursuant to Section 12.5.2.2 must be made as soon as reasonably possible after the Contribution is made, unless the required disclosure is already on file.¶
Participants who realize that IPR meeting the conditions of Section 12.5.7 may Cover technology that will be or has been incorporated into a Contribution, or is seriously being discussed in a working group, are strongly encouraged to make a preliminary IPR disclosure. That IPR disclosure should be made as soon after coming to the realization as reasonably possible, not waiting until the Contribution is actually made.¶
If an IETF Participant first learns of IPR that meets the conditions of Section 12.5.7 that may Cover a Contribution by another party, for example a new patent application or the discovery of a relevant patent in a patent portfolio, after the Contribution is made, an IPR disclosure must be made as soon as reasonably possible after the Contribution or IPR becomes reasonably and personally known to the Participant.¶
By the nature of their office, IETF Area Directors or persons assisting them may become aware of Contributions late in the process (for example at IETF Last Call or during IESG review) and, therefore in such cases, cannot reasonably be expected to disclose IPR Covering those Contributions until they become aware of them.¶
IPR disclosures must be made by following the instructions at https://www.ietf.org/ipr-instructions. IPR disclosures and other IPR-related information, including licensing information, must not be included in RFCs or other IETF Contributions. The RFC Editor will remove any IPR-related information from Contributions prior to publication as an RFC.¶
An IPR disclosure must include the following information to the extent reasonably available to the discloser: (a) the numbers of any issued patents or published patent applications (or indicate that the disclosure is based on unpublished patent applications), (b) the name(s) of the inventor(s) (with respect to issued patents and published patent applications), (c) the specific IETF Document(s) or activity affected, and (d) if the IETF Document is an Internet-Draft, its specific version number. In addition, if it is not reasonably apparent which part of an IETF Document is allegedly Covered by disclosed IPR, then it is helpful if the discloser identifies the sections of the IETF Document that are allegedly Covered by such disclosed IPR.¶
Those who disclose IPR should be aware that as Internet-Drafts evolve, text may be added or removed, and it is recommended that they keep this in mind when composing text for disclosures.¶
Unless sufficient information to identify the issued patent was disclosed when the patent application was disclosed, an IPR disclosure must be updated or a new disclosure made promptly after any of the following has occurred: (1) the publication of a previously unpublished patent application, (2) the abandonment of a patent application, (3) the issuance of a patent on a previously disclosed patent application, or (4) a material change to the IETF Document covered by the Disclosure that causes the Disclosure to be covered by additional IPR. If the patent application was abandoned, then the new IPR disclosure must explicitly withdraw any earlier IPR disclosures based on the application. IPR disclosures against a particular Contribution are assumed to be inherited by revisions of the Contribution and by any RFCs that are published from the Contribution unless the disclosure has been updated or withdrawn.¶
If an IPR holder files patent applications in additional countries which refer to, and the claims of which are substantially identical to, the claims of a patent or patent application previously disclosed in an IPR disclosure, the IPR holder is not required to make a new or updated IPR disclosure as a result of filing such applications or the issuance of patents on such applications.¶
New or revised IPR disclosures may be made voluntarily at any other time, provided that licensing information may only be updated in accordance with Section 12.5.6 item 3.¶
Any person may submit an update to an existing IPR disclosure. If such update is submitted by a person other than the submitter of the original IPR disclosure (as identified by name and email address), then the IETF Secretariat shall attempt to contact the original submitter to verify the update. If the original submitter responds that the proposed update is valid, the Secretariat will update the IPR disclosure accordingly. If the original submitter responds that the proposed update is not valid, the IETF Secretariat will not update the IPR disclosure. If the original submitter fails to respond after the IETF Secretariat has made three separate inquiries and at least 30 days have elapsed since the initial inquiry was made, then the IETF Secretariat will inform the submitter of the proposed update that the update was not validated and that the updater must produce legally sufficient evidence that the submitter (or his/her employer) owns or has the legal right to exercise control over the IPR subject to the IPR disclosure. If such evidence is satisfactory to the IETF Secretariat, after consultation with the IETF legal counsel, then the IETF Secretariat will make the requested update. If such evidence is not satisfactory, then the IETF Secretariat will not make the requested update.¶
The requirement to make an IPR disclosure is not satisfied by the submission of a blanket statement that IPR may exist on every Contribution or a general category of Contributions. This is the case because the aim of the disclosure requirement is to provide information about specific IPR against specific technology under discussion in the IETF. The requirement is also not satisfied by a blanket statement of willingness or commitment to license all potential IPR Covering such technology under fair, reasonable, and non-discriminatory terms for the same reason. However, the requirement for an IPR disclosure is satisfied by a blanket statement of the IPR discloser's commitment to license all of its IPR meeting the requirements of Section 12.5.7 (and either Section 12.5.2.1 or Section 12.5.2.2) to implementers of an IETF specification on a royalty-free (and otherwise reasonable and non-discriminatory) basis as long as any other terms and conditions are disclosed in the IPR disclosure.¶
Since IPR disclosures will be used by IETF working groups during their evaluation of alternative technical solutions, it is helpful if an IPR disclosure includes information about licensing of the IPR in case Implementing Technologies require a license. Specifically, it is helpful to indicate whether, upon approval by the IESG for publication as an RFC of the relevant IETF specification(s), all persons will be able to obtain the right to implement, use, distribute, and exercise other rights with respect to an Implementing Technology a) under a royalty-free and otherwise reasonable and non-discriminatory license, or b) under a license that contains reasonable and non-discriminatory terms and conditions, including a reasonable royalty or other payment, or c) without the need to obtain a license from the IPR holder (e.g., a covenant not to sue with or without defensive suspension, as described in Section 12.5.11).¶
The inclusion of a licensing declaration is not mandatory, but it is encouraged so that the working groups will have as much information as they can during their deliberations. If the inclusion of a licensing declaration in an IPR disclosure would significantly delay its submission, then the discloser may submit an IPR disclosure without a licensing declaration and then submit a new IPR disclosure when the licensing declaration becomes available. IPR disclosures that voluntarily provide text that includes licensing information, comments, notes, or URLs for other information may also voluntarily include details regarding specific licensing terms that the IPR holder intends to offer to implementers of Implementing Technologies, including maximum royalties.¶
It is likely that IETF will rely on licensing declarations and other information that may be contained in an IPR disclosure and that implementers will make technical, legal, and commercial decisions on the basis of such commitments and information. Thus, when licensing declarations and other information, comments, notes, or URLs for further information are contained in an IPR disclosure, the persons making such disclosure agree and acknowledge that the commitments and information contained in such disclosure shall be irrevocable and will attach, to the extent permissible by law, to the associated IPR, and all implementers of Implementing Technologies will be justified and entitled to rely on such materials in relating to such IPR, whether or not such IPR is subsequently transferred to a third party by the IPR holder making the commitment or providing the information. IPR holders making IPR disclosures that contain licensing declarations or providing such information, comments, notes, or URLs for further information must ensure that such commitments are binding on any transferee of the relevant IPR, and that such transferee will use reasonable efforts to ensure that such commitments are binding on a subsequent transferee of the relevant IPR, and so on.¶
Licensing declarations must be made by people who are authorized to make such declarations as discussed in Section 12.5.7 of this document.¶
IPR disclosures under Section 12.5.2.1 and Section 12.5.2.2 are required with respect to IPR (a) that is owned, directly or indirectly, by the individual Contributor or his/her employer or sponsor (if any), or (b) that such persons otherwise have the right to license or assert, or (c) from which such persons derive a direct or indirect pecuniary benefit, or (d) as to which an individual Contributor is listed as an inventor on the relevant patent or patent application.¶
If a Contribution is oral and is not followed promptly by a written disclosure of the same material, and if such oral Contribution would be subject to a requirement that an IPR Disclosure be made (had such oral Contribution been written), then the Contributor must accompany such oral Contribution with an oral declaration that he/she is aware of relevant IPR in as much detail as reasonably possible or file an IPR Declaration with respect to such oral Contribution that otherwise complies with the provisions of Section 12.5.2 through Section 12.5.7 above.¶
As described in Section 12.5.4, the IETF will make available a public facility (e.g., a web page and associated database) for the posting of IPR disclosures conforming with the disclosure requirements of this policy. In addition, the IETF may make available a public facility for the posting of other IPR-related information and disclosures that do not satisfy the requirements of this policy but which may otherwise be informative and relevant to the IETF ("General Disclosures"). Such General Disclosures may include, among other things, "blanket disclosures" that do not contain a royalty-free licensing commitment as described in Section 12.5.5.3, disclosures of IPR that do not identify the specific IETF Documents Covered by the disclosed IPR, and licensing statements or commitments that are applicable generally and not to specific IPR disclosures. All of this information may be helpful to the IETF community, and its disclosure is encouraged. However, General Disclosures do not satisfy an IETF Participant's obligation to make IPR disclosures as required by this policy.¶
In some cases, if an IPR disclosure submitted by an IETF Participant does not meet the requirements of this policy, the IETF may elect to post the non-conforming IPR disclosure as a General Disclosure in order to provide the greatest amount of information to the IETF community. This action does not excuse the IETF Participant from submitting a new IPR disclosure that conforms with the requirements of Section 12.5.2 through Section 12.5.7. The IETF reserves the right to decline to publish General Disclosures that are not relevant to IETF activities, that are, or are suspected of being, defamatory, false, misleading, in violation of privacy or other applicable laws or regulations, or that are in a format that is not suitable for posting on the IETF facility that has been designated for General Disclosures.¶
There may be cases in which individuals are not permitted by their employers or by other factors to disclose the existence or substance of patent applications or other IPR. Since disclosure is required for anyone making a Contribution or Participating in IETF activities, a person who is not willing or able to disclose IPR for this reason, or any other reason, must not contribute to or participate in IETF activities with respect to technologies that he or she reasonably and personally knows may be Covered by IPR which he or she will not disclose, unless that person knows that his or her employer or sponsor will make the required disclosures on his or her behalf.¶
Contributing to or Participating in IETF activities about a technology without making required IPR disclosures is a violation of IETF policy.¶
In addition to any remedies or defenses that may be available to implementers and others under the law with respect to such a violation (e.g., rendering the relevant IPR unenforceable), sanctions are available through the normal IETF processes for handling disruptions to IETF work. See [RFC6701] for details regarding the sanctions defined in various existing Best Current Practice documents.¶
In general, IETF working groups prefer technologies with no known IPR claims or, for technologies with claims against them, an offer of royalty-free licensing. However, to solve a given technical problem, IETF working groups have the discretion to adopt a technology as to which IPR claims have been made if they feel that this technology is superior enough to alternatives with fewer IPR claims or free licensing to outweigh the potential cost of the licenses. To assist these working groups, it is helpful for the IPR claimants to declare, in their IPR Declarations, the terms, if any, on which they are willing to license their IPR Covering the relevant IETF Documents.¶
When adopting new technologies, the participants in an IETF working group are expected to evaluate all the relevant tradeoffs from their perspective. Most of the time these considerations are based purely on technical excellence, but IPR considerations may also affect the evaluation and specific licensing terms may affect the participants' opinion on the desirability of adopting a particular technology.¶
The IETF has no official preference among different licensing terms beyond what was stated at the beginning of this section. However, for information and to assist participants in understanding what license conditions may imply, what follows are some general observations about some common types of conditions. The following paragraphs are provided for information only:¶
When there is no commitment to license patents covering the technology, this creates uncertainty that obviously is concerning. These concerns do not exist when there is a commitment to license, but the license terms can still differ greatly. Some common conditions include 1) terms that are fair, reasonable, and non- discriminatory, and which may bear royalties or other financial obligations (FRAND or RAND); 2) royalty-free terms that are otherwise fair, reasonable, and non-discriminatory (RAND-z); and 3) commitments not to assert declared IPR, possibly conditional on reciprocity. Open source projects, for instance, often prefer the latter two. Note that licenses often come with complex terms that have to be evaluated in detail, and this crude classification may not be sufficient to make a proper evaluation. For instance, licenses may also include reciprocity and defensive suspension requirements that require careful evaluation.¶
The level of use of a technology against which IPR is disclosed is also an important factor in weighing IPR encumbrances and associated licensing conditions against technical merits. For example, if technologies are being considered for a mandatory-to-implement change to a widely deployed protocol, the hurdle should be very high for encumbered technologies, whereas a similar hurdle for a new protocol could conceivably be lower.¶
IETF working groups and IETF areas may, however, adopt stricter requirements in specific cases. For instance, the IETF Security Area has adopted stricter requirements for some security technologies. It has become common to have a mandatory-to-implement security technology in IETF technology specifications. This is to ensure that there will be at least one common security technology present in all implementations of such a specification that can be used in all cases. This does not limit the specification from including other security technologies, the use of which could be negotiated between implementations. An IETF consensus has developed that no mandatory-to-implement security technology can be specified in an IETF specification unless it has no known IPR claims against it or a royalty-free license is available to implementers of the specification. It is possible to specify such a technology in violation of this principle if there is a very good reason to do so and if that reason is documented and agreed to through IETF consensus. This limitation does not extend to other security technologies in the same specification if they are not listed as mandatory to implement.¶
It should also be noted that the absence of IPR disclosures at any given time is not the same thing as the knowledge that there will be no IPR disclosure in the future, or that no IPR Covers the relevant technology. People or organizations not currently involved in the IETF or people or organizations that discover IPR they feel to be relevant in their patent portfolios can make IPR disclosures at any time.¶
It should be noted that the validity and enforceability of any IPR may be challenged for legitimate reasons outside the IETF. The mere existence of an IPR disclosure should not be taken to mean that the disclosed IPR is valid or enforceable or actually Covers a particular Contribution. Although the IETF can make no actual determination of validity, enforceability, or applicability of any particular IPR, it is reasonable that individuals in a working group or the IESG will take into account their own views of the validity, enforceability, or applicability of IPR in their evaluation of alternative technologies.¶
The IETF must have change control over the technology described in any Standards Track IETF Documents in order to fix problems that may be discovered or to produce other derivative works.¶
In some cases, the developer of patented or otherwise controlled technology may decide to hand over to the IETF the right to evolve the technology (a.k.a., "change control"). The implementation of an agreement between the IETF and the developer of the technology can be complex. (See [RFC1790] and [RFC2339] for examples.)¶
Note that there is no inherent prohibition against a Standards Track IETF Document making a normative reference to proprietary technology. For example, a number of IETF standards support proprietary cryptographic transforms.¶
Section 8.1.1 states:¶
If the technology required to implement the specification requires patented or otherwise controlled technology, then the set of implementations must demonstrate at least two independent, separate and successful uses of the licensing process.¶
A key word in this text is "requires". The mere existence of disclosed IPR does not necessarily mean that licenses are actually required in order to implement the technology.¶
IETF Documents must not contain any mention of specific IPR. All specific IPR disclosures must be submitted as described in Section 12.5. Readers should always refer to the online web page https://www.ietf.org/ipr/ to get a full list of IPR disclosures received by the IETF concerning any Contribution.¶
