IETF TRUST
Legal Provisions Relating to IETF Documents
Effective Date: December 28, 2009
1. Background
The IETF Trust was formed on December 15, 2005, for, among other things, the purpose of acquiring, holding, maintaining and licensing certain existing and future intellectual property used in connection with the Internet standards process and its administration, for the advancement of science and technology associated with the Internet and related technology. Accordingly, pursuant to RFC 5378, Contributors grant the IETF Trust certain licenses with respect to their IETF Contributions. In RFC 5377, the IETF Community has provided the IETF Trust with guidance regarding licenses that the IETF Trust should grant to others with respect to such IETF Contributions and IETF Documents. These Legal Provisions describe the rights and licenses that the IETF Trust grants to others with respect to such IETF Contributions and IETF Documents; as well as certain restrictions, limitations and notices relating to IETF Documents. These Legal Provisions also apply to other document streams that have requested that the IETF Trust act as licensing administrator, as described in Section 8 below. Capitalized terms used in these Legal Provisions that are not otherwise defined have the meanings set forth in RFC 5378.
2. Applicability of these Legal Provisions.
a. These Legal Provisions are effective as of December 28, 2009 (the "Effective Date").
b. The licenses granted by the IETF Trust pursuant to these Legal Provisions apply only with respect to (i) IETF Contributions (including Internet-Drafts) that are submitted to the IETF following the Effective Date, and (ii) IETF RFCs and other IETF Documents that are published after the Effective Date.
c. IETF Contributions made, and IETF Documents published, prior to the Effective Date ("Pre-Existing IETF Documents") remain subject to the licensing provisions of the IETF copyright policy document in effect at the time of their contribution or publication, as applicable, including RFCs 1310, 1602, 2026, 3978 and 4748 and previous versions of these Legal Provisions.
d. In most cases, rights to Pre-Existing IETF Documents that are not expressly granted under these RFCs can only be obtained by requesting such rights directly from the document authors. The IETF Trust and the Internet Society do not become involved in making such requests to document authors.
e. These Legal Provisions may be amended from time to time by the IETF Trust in a manner consistent with the guidance provided by the IETF community and its own operating procedures. Any amendment to these Legal Provisions shall be posted for review at http://trustee.ietf.org/policyandprocedures.html and shall become effective on a date specified by the IETF Trust, but no earlier than thirty (30) days following its posting. Such amendment shall apply with respect to all IETF Contributions made and IETF Documents published following the effective date of such amendment. All prior versions of these Legal Provisions shall continue to be posted at http://trustee.ietf.org/policyandprocedures.html for reference with respect to IETF Contributions and IETF Documents as to which they may apply.
3. Licenses to IETF Documents and IETF Contributions.a. License For Use Within the IETF Standards Process. The IETF Trust hereby grants to each participant in the IETF Standards Process, to the greatest extent that it is permitted to do so, a non-exclusive, royalty-free, worldwide right and license under all copyrights and rights of authors granted to the IETF Trust:
i. to copy, publish, display and distribute IETF Contributions and IETF Documents, in whole or in part, as part of the IETF Standards Process, and
ii. to translate IETF Contributions and IETF Documents, in whole or part, into languages other than English as part of the IETF Standards Process, and
iii. unless explicitly disallowed in the notices contained in an IETF Contribution or IETF Document (as specified in Section 6.c below), to modify or prepare derivative works of such IETF Contributions or IETF Documents, in whole or in part, as part of the IETF Standards Process.
b. IETF Standards Process. The term IETF Standards Process has the meaning assigned to it in RFC 5378. In addition, the IETF Trust interprets the IETF Standards Process to include the archiving of IETF Documents in perpetuity for reference in support of IETF activities and the implementation of IETF standards and specifications.
c. Licenses For Use Outside the IETF Standards Process. In addition to the rights granted with respect to Code Components described in Section 4 below, the IETF Trust hereby grants to each person who wishes to exercise such rights, to the greatest extent that it is permitted to do so, a non-exclusive, royalty-free, worldwide right and license under all copyrights and rights of authors:
i. to copy, publish, display and distribute IETF Contributions and IETF Documents in full and without modification,
ii. to translate IETF Contributions and IETF Documents into languages otherthan English, and to copy, publish, display and distribute such translated IETF Contributions and IETF Documents in full and without modification,
iii. to copy, publish, display and distribute unmodified portions of IETF Contributions and IETF Documents and translations thereof, provided that: (x) each such portion is clearly attributed to IETF and identifies the RFC or other IETF Document or IETF Contribution from which it is taken, (y) all IETF legends, legal notices and indications of authorship IETF Trust Legal Provisions Relating to IETF Documents Effective Date: December 28, 2009 3 contained in the original IETF RFC must also be included where any substantial portion of the text of an IETF RFC, and in any event where more than one-fifth of such text, is reproduced in a single document or series of related documents.
d. Licenses that are not Granted. The following licenses are not granted pursuant to these Legal Provisions:
i. any license to modify IETF Contributions or IETF Documents, or portions thereof (other than to make translations or to extract, use and modify Code Components as permitted under the licenses granted under Section 4 of these Legal Provisions) in any context outside the IETF Standards Process, or
ii. any license to publish, display or distribute IETF Contributions or IETF Documents, or portions thereof, without the required legends and notices described in these Legal Provisions.
e. Requesting Additional Rights. Anyone who wishes to request license rights from the IETF Trust in addition to those granted under these Legal Provisions may submit such request to trustees@ietf.org. Such request will be considered by the IETF Trust, which will make a decision regarding the request in its sole discretion and inform the requester of its disposition. In addition, individual Contributors may be contacted regarding licenses to their IETF Contributions. The IETF Trust does not limit the ability of IETF Contributors to license their Contributions, so long as those licenses do not affect the rights granted to the IETF Trust under RFC 5378.
4. License to Code Components.
a. Definition. IETF Contributions and IETF Documents often include components intended to be directly processed by a computer ("Code Components"). A list of common Code Components can be found at http://trustee.ietf.org/license-info/.
b. Identification. Text in IETF Contributions and IETF Documents of the types identified in Section 4.a above shall constitute "Code Components". In addition, any text found between the markers <CODE BEGINS> and <CODE ENDS>, or otherwise clearly labeled as a Code Component, shall be considered a "Code Component".
c. License. In addition to the licenses granted under Section 3, unless one of the legends contained in Section 6.c.i or 6.c.ii is included in an IETF Document containing Code Components, such Code Components are also licensed to each person who wishes to receive such a license on the terms of the "Simplified BSD License", as described below. If a licensee elects to apply the BSD License to a Code Component, then the additional licenses and restrictions set forth in Section 3 and elsewhere in these Legal Provisions shall not apply thereto. Note that this license is specifically offered for IETF Documents and may not be available for Alternate Stream documents. See Section 8 for licensing information for the appropriate stream.

right.
b. Supersedure. The terms of any license granted under these Legal Provisions may be
superseded by a written agreement between the IETF Trust and the licensee that specifically
references and supersedes the relevant provisions of these Legal Provisions, except that (i) the
IETF Trust shall in no event be authorized to grant rights with respect to any Contribution in
excess of those which it has been granted by the Contributor, and (ii) the rights granted shall not
be less than those otherwise granted under these Legal Provisions.
c. Pre-5378 Material. In some cases, IETF Contributions or IETF Documents may
contain material from IETF Contributions or IETF Documents published or made publicly
available before November 10, 2008 as to which the persons controlling the copyright in such
material have not granted rights to the IETF Trust under the terms of RFC 5378 ("Pre-5378
Material"). If a Contributor includes the legend contained in Section 6.c.iii of these Legal
Provisions on such IETF Contributions or IETF Documents containing Pre-5378 Materials, the
IETF Trust agrees that it shall not grant any third party the right to use such Pre-5378 Material
outside the IETF Standards Process unless and until it has obtained sufficient rights to do so from
the persons controlling the copyright in such Pre-5378 Material. Where practical, Contributors
are encouraged to identify which portions of such IETF Contributions and IETF Documents
contain Pre-5378 Material, including the source (by RFC number or otherwise) of the Pre-5378
Material.
6. Text To Be Included in IETF Documents.
The following text must be included in each IETF Document as specified below.
The IESG shall specify the manner and location of such text for Internet-Drafts.

with respect to this document.
c. Derivative Works and Publication Limitations. If a Contributor chooses to limit
the right to make modifications and derivative works of an IETF Contribution, then one of the
notices in clause (i) or (ii) below must be included. Note that an IETF Contribution with such a
notice cannot become a Standards Track document or, in most cases, a working group document.
If an IETF Contribution contains pre-5378 Material as to which the IETF Trust has not been
granted, or may not have been granted, the necessary permissions to allow modification of such
pre-5378 Material outside the IETF Standards Process, then the notice in clause (iii) may be
included by the Contributor of such IETF Contribution to limit the right to make modifications to
such pre-5378 Material outside the IETF Standards Process.
i. If the Contributor does not wish to allow modifications, but does wish to allow publication as an RFC:

format it for publication as an RFC or to translate it into languages other than English.
ii. If the Contributor does not wish to allow modifications nor to allow publication as an RFC:
This document may not be modified, and derivative works of it may not be created, and it may not
be published except as an Internet-Draft.
iii. If an IETF Contribution contains pre-5378 Material as to which the IETF Trust has not been granted, or may not have been granted, the necessary permissions to allow modification of such pre-5378 Material outside the IETF Standards Process:
This document may contain material from IETF Documents or IETF Contributions published or
made publicly available before November 10, 2008. The person(s) controlling the copyright in
some of this material may not have granted the IETF Trust the right to allow modifications of such
material outside the IETF Standards Process. Without obtaining an adequate license from the
person(s) controlling the copyright in such materials, this document may not be modified outside
the IETF Standards Process, and derivative works of it may not be created outside the IETF
Standards Process, except to format it for publication as an RFC or to translate it into languages
other than English.
d. BSD License Notification. In lieu of the complete text of the Simplified BSD
License set forth in Section 4.c, a person who elects to license a Code Component under the
Simplified BSD License as described in Section 4.c may use the following notification in the
program or other file that includes the Code Component:
Copyright (c) <insert year> IETF Trust and the persons identified as authors of the code.
All rights reserved.
Redistribution and use in source and binary forms, with or without modification, is permitted pursuant to,
and subject to the license terms contained in, the Simplified BSD License set forth in Section 4.c of the
IETF Trust’s Legal Provisions Relating to IETF Documents (http://trustee.ietf.org/license-info).
7. Terms Applicable to All IETF Documents.
The following legal terms apply to all IETF Documents:
a. ALL DOCUMENTS AND THE INFORMATION CONTAINED THEREIN
ARE PROVIDED ON AN "AS IS" BASIS AND THE CONTRIBUTOR, THE
ORGANIZATION HE/SHE REPRESENTS OR IS SPONSORED BY (IF ANY), THE
INTERNET SOCIETY, THE IETF TRUST, THE INTERNET ENGINEERING TASK FORCE
AND ANY APPLICABLE MANAGERS OF ALTERNATE STREAM DOCUMENTS, AS
DEFINED IN SECTION 8 BELOW, DISCLAIM ALL WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTY THAT THE USE OF
THE INFORMATION THEREIN WILL NOT INFRINGE ANY RIGHTS OR ANY IMPLIED
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
b. The IETF Trust takes no position regarding the validity or scope of any
Intellectual Property Rights or other rights that might be claimed to pertain to the implementation
or use of the technology described in any IETF Document or the extent to which any license
under such rights might or might not be available; nor does it represent that it has made any
independent effort to identify any such rights.
c. Copies of Intellectual Property disclosures made to the IETF Secretariat and
any assurances of licenses to be made available, or the result of an attempt made to obtain a
general license or permission for the use of such proprietary rights by implementers or users of
this specification can be obtained from the IETF on-line IPR repository at
http://www.ietf.org/ipr.
d. The IETF invites any interested party to bring to its attention any copyrights,
patents or patent applications, or other proprietary rights that may cover technology that may be
required to implement any standard or specification contained in an IETF Document. Please
address the information to the IETF at ietf-ipr@ietf.org.
e. The definitive version of an IETF Document is that published by, or under the
auspices of, the IETF. Versions of IETF Documents that are published by third parties,
including those that are translated into other languages, should not be considered to be definitive
versions of IETF Documents. The definitive version of these Legal Provisions is that published
by, or under the auspices of, the IETF. Versions of these Legal Provisions that are published by
third parties, including those that are translated into other languages, should not be considered to
be definitive versions of these Legal Provisions.
f. For the avoidance of doubt, each Contributor licenses each Contribution that
he or she makes to the IETF Trust pursuant to the provisions of RFC 5378. No language to the
contrary, or terms, conditions or rights that differ from or are inconsistent with the rights and
licenses granted under RFC 5378, shall have any effect and shall be null and void, whether
published or posted by such Contributor, or included with or in such Contribution.
8. Application to non-IETF Stream Documents
a. General. These Legal Provisions have been developed by the IETF Trust for the
benefit and use of the IETF community in accordance with the guidance provided in RFC 5377.
As such, these Legal Provisions apply to all IETF Contributions and IETF Documents that are in
the "IETF Document Stream" as defined in Section 5.1.1 of RFC 4844 (i.e., those that are
contributed, developed, edited and published as part of the IETF Standards Process). As
indicated in Section 4 of RFC 5378, the IETF rules regarding copyrights (which are embodied in
these Legal Provisions) do not by their terms cover documents or materials contributed or
published outside of the IETF Document Stream, even if they are referred to as Internet-Drafts or
RFCs and/or published by the RFC Editor. The IAB Document Stream, the IRTF Document
Stream and the Independent Submission Stream, each as defined in Section 5.1 of RFC 4844 are
referred to collectively herein as "Alternate Streams".
b. Adoption by Alternate Streams. The legal rules that apply to documents in
Alternate Streams are established by the managers of those Alternate Streams as defined in RFC
4844. (i.e., the Internet Architecture Board (IAB), Internet Research Steering Group (IRSG) and
Independent Submission Editor). These managers may elect, through their own internal
processes, to cause these Legal Provisions 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 these Legal Provisions and to utilize the IETF Trust as the
licensing administrator for such Alternate Stream, the IETF Trust will update these Legal
Provisions to reflect the specific manner in which it will so act, and shall do so consistently with
the stated wishes of the Alternate Stream manager to the extent consistent with the IETF Trust’s
legal obligations and the instructions of the IETF community embodied in RFC 5377 and
elsewhere.
c. Alternate Stream License.
i. Unless otherwise specified below, for each Alternate Stream for which the
IETF Trust acts as licensing administrator, from the date on which these Legal Provisions are
effective with respect to such Alternate Stream (as specified below) the IETF Trust shall accept
licenses of copyrights in documents granted to the IETF Trust by contributors to Alternate
Stream as though granted pursuant to RFC 5378, and shall grant licenses to others on the terms
of these Legal Provisions.
ii. Each occurrence of the term "IETF Contribution" and "IETF Document"
in these Legal Provisions shall be read to mean a Contribution or document in such Alternate
Stream, as the case may be. The disclaimer in Section 7.a of these Legal Provisions shall apply
to the manager of such Alternate Stream as defined in RFC 4844 as though such manager were
expressly listed in Section 7.a.
iii. The license grant in Section 3.a of these Legal Provisions with respect to
Alternate Stream documents shall not be limited to the IETF Standards Process, and all
references to the IETF Standards Process in Section 3.a shall be omitted with respect to licenses
of Alternate Stream documents, and correspondingly Section 3.c hereof shall not apply with
respect to Alternate Stream documents.
iv. Alternate Stream contributions made, and Alternate Stream documents
published, prior to the application of these Legal Provisions to such Alternate Stream remain
subject to the licensing provisions in effect for such Alternate Stream at the time of their
contribution or publication, as applicable.
d. Responsibility of Alternate Stream Contributors. Sections 5.c and 6.c.iii of these
Legal Provisions shall not apply to Alternate Stream documents, thus contributors of
Contribution to Alternate Streams must assure themselves that they comply with the
representations and warranties required under RFC 5378, including under Section 5.6 of RFC
5378, with respect to the entirety of their Alternate Stream Contributions prior to making the
contribution.
e. IAB Document Stream. Pursuant to Section 11 of RFC 5378, the IAB requested,
as of April 4, 2008, that the IETF Trust act as licensing administrator for the IAB Document
Stream and that these Legal Provisions be applied to documents submitted and published in the
IAB Document Stream following the Effective Date of RFC 5378. Section 4 of these Legal
Provisions shall not apply to documents in the IAB Document Stream, and all references to
Section 4 hereof shall be disregarded with respect to documents in the IAB Document Stream
pursuant to RFC 5745 published on December 21, 2009.
f. Independent Submission Stream. Pursuant to RFC 5744 published on December
17, 2009, the manager of the Independent Submission Stream has requested that the IETF Trust
act as licensing administrator for the Independent Submission Stream and that these Legal
Provisions be applied to documents submitted and published in the Independent Submission
Stream following December 28, 2009. Section 4 of these Legal Provisions shall not apply to
documents in the Independent Submission Stream, and all references to Section 4 hereof shall be
disregarded with respect to documents in the Independent Submission Stream.
g. IRTF Document Stream. Pursuant to RFC 5743 published on December 24,
2009, the manager of the IRTF Document Stream has requested that the IETF Trust act as
licensing administrator for the IRTF Document Stream and that these Legal Provisions be
applied to documents submitted and published in the IRTF Document Stream following
December 28, 2009. Section 4 of these Legal Provisions shall not apply to documents in the
IRTF Document Stream, and all references to Section 4 hereof shall be disregarded with respect
to documents in the IRTF Document Stream.
