All Rights Reserved.Abstract   The IETF policies about rights in Contributions to the IETF are   designed to ensure that such Contributions can be made available to   the IETF and Internet communities while permitting the authors to   retain as many rights as possible.  This memo details the IETF   policies on rights in Contributions to the IETF.  It also describes   the objectives that the policies are designed to meet.  This memo   updatesRFC 2026, and, withRFC 3668, replaces Section 10 ofRFC2026.Table of Contents1.  Definitions. . . . . . . . . . . . . . . . . . . . . . . . . .22.

Other terms, including "IESG," "ISOC," "IAB" and "RFC   Editor," are defined in [RFC 2028].   a. "IETF":  In the context of this document, the IETF includes all      individuals who participate in meetings, working groups, mailing      lists, functions and other activities which are organized or      initiated by ISOC, the IESG or the IAB under the general      designation of the Internet Engineering Task Force or IETF, but      solely to the extent of such participation.   b. "IETF Standards Process": the activities undertaken by the IETF in      any of the settings described in 1(c) below.   c. "IETF Contribution": any submission to the IETF intended by the      Contributor for publication as all or part of an Internet-Draft or      RFC (except for RFC Editor Contributions described below) and any      statement made within the context of an IETF activity.  Such      statements include oral statements in IETF sessions, as well as      written and electronic communications made at any time or place,      which are addressed to:      o  the IETF plenary session,      o  any IETF working group or portion thereof,      o  the IESG, or any member thereof on behalf of the IESG,      o  the IAB or any member thereof on behalf of the IAB,Bradner                  Best Current Practice                  [Page 2]

RFC 3667               IETF Rights in Submissions          February 2004      o  any IETF mailing list, including the IETF list itself, any         working group or design team list, or any other list         functioning under IETF auspices,      o  the RFC Editor or the Internet-Drafts function (except for RFC         Editor Contributions described below).      Statements made outside of an IETF session, mailing list or other      function, that are clearly not intended to be input to an IETF      activity, group or function, are not IETF Contributions in the      context of this document.   d. "Internet-Draft": temporary documents used in the IETF and RFC      Editor processes.  Internet-Drafts are posted on the IETF web site      by the IETF Secretariat and have a nominal maximum lifetime in the      Secretariat's public directory of 6 months, after which they are      removed.  Note that Internet-Drafts are archived many places on      the Internet, and not all of these places remove expired      Internet-Drafts.  Internet-Drafts that are under active      consideration by the IESG are not removed from the Secretariat's      public directory until that consideration is complete.  In      addition, the author of an Internet-Draft can request that the      lifetime in the Secretariat's public directory be extended before      the expiration.   e. "RFC": the basic publication series for the IETF.  RFCs are      published by the RFC Editor and once published are never modified.      (See[RFC 2026] Section 2.1)   f. "RFC Editor Contribution": An Internet-Draft intended by the      Contributor to be submitted to the RFC Editor for publication as      an Informational or Experimental RFC but not intended to be part      of the IETF Standards Process.   g. "IETF Internet-Drafts": Internet-Drafts other than RFC Editor      Contributions.  Note that underSection 3.3(a) the grant of rights      in regards to IETF Internet-Drafts as specified in this document      is perpetual and irrevocable and thus survives the Secretariat's      removal of an Internet-Draft from the public directory, except as      limited bySection 3.3(a)(C).  (See [RFC 2026] Sections2.2 and8)   h. "IETF Documents":  RFCs and Internet-Drafts except for Internet-      Drafts that are RFC Editor Contributions and the RFCs that are      published from them.   i. "RFC Editor Documents":  RFCs and Internet-Drafts that are RFC      Editor Contributions and the RFCs that may be published from them.   j. "Contribution": IETF Contributions and RFC Editor Contributions.Bradner                  Best Current Practice                  [Page 3]

RFC 3667               IETF Rights in Submissions          February 2004   k. "Contributor": an individual submitting a Contribution.   l. "Reasonably and personally known": means 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.2. Introduction   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.)   This document details the rights that the IETF requires in IETF   Contributions and rights the IETF, as publisher of Internet-Drafts,   requires in all such Drafts including RFC Editor Contributions.  The   RFC Editor may also define additional rights required for RFC Editor   Contributions.   In order for works to be used within the IETF Standards Process or to   be published as Internet-Drafts, certain limited rights in all   Contributions must be granted to the IETF and Internet Society   (ISOC). In addition, Contributors must make representations to IETF   and ISOC regarding their ability to grant these rights.  These   necessary rights and representations have until now been laid out inSection 10 of [RFC 2026].  In the years since [RFC 2026] was   published there have been a number of times when the exact intent ofSection 10 has been the subject of vigorous debate within the IETF   community.  The aim of this document is to clarify various   ambiguities inSection 10 of [RFC 2026] that led to these debates and   to amplify the policy in order to clarify what the IETF is currently   doing.Section 1 gives definitions used in describing these policies.   Sections3,4,5 and6 of this document address the rights in   Contributions previously covered bySection 10 of [RFC 2026] and theBradner                  Best Current Practice                  [Page 4]

RFC 3667               IETF Rights in Submissions          February 2004   "Note Well" explanatory text presented at many IETF activities.   Sections7 and8 then explain the rationale for these provisions,   including some of the clarifications that have become understood   since the adoption of [RFC 2026].  The rules and procedures set out   in this document are not intended to substantially modify or alter   the IETF's current policy toward Contributions.   A companion document [RFC 3668] deals with rights in technologies   developed or specified as part of the IETF Standards Process.  This   document is not intended to address those issues.   The rights addressed in this document fall into the following   categories:   o  rights to make use of contributed material   o  copyrights in IETF documents   o  rights to produce derivative works   o  rights to use trademarks   This document 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 in any   Contributions they make.3. Rights in IETF Contributions   The following are the rights the IETF requires in all IETF   Contributions:3.1.  General Policy   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.3.2.  Confidentiality Obligations   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.Bradner                  Best Current Practice                  [Page 5]

RFC 3667               IETF Rights in Submissions          February 20043.3.  Granting of Rights and Permissions   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, and to grant the following   rights, on his or her own behalf and on behalf of the organization   the Contributor represents or is sponsored by (if any) when   submitting the Contribution.   a. To the extent that a Contribution or any portion thereof is      protected by copyright and other rights of authorship, the      Contributor, and each named co-Contributor, and the organization      he or she represents or is sponsored by (if any) grant a      perpetual, irrevocable, non-exclusive, royalty-free, world-wide      right and license to the ISOC and the IETF under all intellectual      property rights in the Contribution:      (A)  to copy, publish, display and distribute the Contribution as           part of the IETF Standards Process or in an Internet-Draft,      (B)  to prepare or allow the preparation of translations of the           Contribution into languages other than English,      (C)  unless explicitly disallowed in the notices contained in a           Contribution [as perSection 5.2 below], to prepare           derivative works (other than translations) that are based on           or incorporate all or part of the Contribution, or comment           upon it, within the IETF Standards Process.

When reproducing Contributions, the IETF           will preserve trademark and service mark identifiers used by           the Contributor of the Contribution, including (TM) and (R)           where appropriate, and      (E)  to extract, copy, publish, display, distribute, modify and           incorporate into other works, for any purpose (and not           limited to use within the IETF Standards Process) any           executable code or code fragments that are included in any           IETF Document (such as MIB and PIB modules), subject to the           requirements ofSection 5 (it also being understood that the           licenses granted under this paragraph (E) shall not be deemed           to grant any right under any patent, patent application orBradner                  Best Current Practice                  [Page 6]

The Contributor grants the IETF and ISOC permission to reference      the name(s) and address(es) of the Contributor(s) and of the      organization(s) s/he represents or is sponsored by (if any).3.4.  Representations and Warranties   With respect to each Contribution, each Contributor represents that   to the best of his or her knowledge and ability:   a. The Contribution properly acknowledges all major Contributors.  A      major Contributor is any person who has materially or      substantially contributed to the IETF Contribution.   b. No information in the Contribution is confidential and the IETF,      ISOC, and its affiliated organizations may freely disclose any      information in the Contribution.   c. 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.   d. The Contributor has not intentionally included in the Contribution      any material which 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.   e. 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.3.5.  No Duty to Publish   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 ofSection 3.4 andSection 3.3 or 4.2.3.6.  Trademarks   Contributors, and each named co-Contributor, who claim trademark   rights in terms used in their IETF Contributions are requested to   state specifically what conditions apply to implementers ofBradner                  Best Current Practice                  [Page 7]

Such   statements should be submitted in the same way as is done for other   intellectual property claims.  (See[RFC 3668] Section 6.)4. Rights in RFC Editor Contributions   The following are the rights the IETF, as the publisher of Internet-   Drafts, requires in all RFC Editor Contributions:4.1.  Requirements fromSection 3   All RFC Editor Contributions must meet the requirements of Sections   3.1, 3.2, 3.4, 3.5 and 3.6.4.2.  Granting of Rights and Permissions   By submission of an RFC Editor Contribution, each person actually   submitting the RFC Editor Contribution, and each named co-   Contributor, is deemed to agree to the following terms and   conditions, and to grant the following rights, on his or her own   behalf and on behalf of the organization the Contributor represents   or is sponsored by (if any) when submitting the RFC Editor   Contribution.   a. To the extent that an RFC Editor Contribution or any portion      thereof is protected by copyright and other rights of authorship,      the Contributor, and each named co-Contributor, and the      organization he or she represents or is sponsored by (if any)      grant a perpetual, irrevocable, non-exclusive, royalty-free,      world-wide right and license to the ISOC and the IETF under all      intellectual property rights in the RFC Editor Contribution for at      least the life of the Internet-Draft:      (A) to copy, publish, display and distribute the RFC Editor          Contribution as an RFC, and      (B) to prepare or allow the preparation of translations of the RFC          into languages other than English.      (C) unless explicitly disallowed in the notices contained in an          RFC Editor Contribution (as perSection 5.2 below), to prepare          derivative works (other than translations) that are based on          or incorporate all or part of the RFC Editor Contribution, or          comment upon it.  The license to such derivative works not          granting the ISOC and the IETF any more rights than the          license to the original RFC Editor Contribution, andBradner                  Best Current Practice                  [Page 8]

RFC 3667               IETF Rights in Submissions          February 2004      (D) to reproduce any trademarks, service marks or trade names          which are included in the RFC Editor Contribution solely in          connection with the reproduction, distribution or publication          of the RFC Editor Contribution and derivative works thereof as          permitted by this paragraph.  When reproducing RFC Editor          Contributions, the IETF will preserve trademark and service          mark identifiers used by the Contributor of the RFC Editor          Contribution, including (TM) and (R) where appropriate.   b. The Contributor grants the IETF and ISOC permission to reference      the name(s) and address(es) of the Contributor(s) and of the      organization(s) s/he represents or is sponsored by (if any).5.  Notices Required in IETF Documents   The IETF requires that certain notices and disclaimers described in   thisSection 5 be reproduced verbatim in all IETF Documents   (including copies, derivative works and translations of IETF   Documents, but subject to the limited exceptions noted inSection5.2).  This requirement protects IETF and its participants from   liabilities connected with these documents.  The copyright notice   also alerts readers that the document is an IETF Document, and that   ISOC claims copyright rights to certain aspects of the document, such   as its layout, the RFC numbering convention and the prefatory   language of the document.  This legend is not intended to imply that   ISOC has obtained ownership of the IETF Contribution itself, which is   retained by the author(s) or remains in the public domain, as   applicable.   Each IETF Document must include the required notices described in   thisSection 5.  The required notices are the following:   a. The IPR Disclosure Acknowledgement described inSection 5.1      (required in all Internet-Drafts).   b. The Derivative Works Limitation described inSection 5.2 (for      specific IETF Documents only).   c. The Publication Limitation described inSection 5.3 (for specific      types of Internet-Drafts only).   d. The Copyright Notice described inSection 5.4 (for all IETF      Documents).   e. The Disclaimer described inSection 5.5 (for all IETF Documents).Bradner                  Best Current Practice                  [Page 9]

RFC 3667               IETF Rights in Submissions          February 20045.1.  IPR Disclosure Acknowledgement (required in all Internet-Drafts      only)   "By submitting this Internet-Draft, I certify that any applicable   patent or other IPR claims of which I am aware have been disclosed,   and any of which I become aware will be disclosed, in accordance withRFC 3668."5.2.  Derivative Works Limitation   If the Contributor desires to eliminate the IETF's right to make   modifications and derivative works of an IETF Contribution (other   than translations), one of the two of the following notices may be   included in the Status of Memo section of an Internet-Draft and   included in a published RFC:   a. "This document may not be modified, and derivative works of it may      not be created, except to publish it as an RFC and to translate it      into languages other than English."   b. "This document may not be modified, and derivative works of it may      not be created."   In the cases of MIB or PIB modules and in other cases where the   Contribution includes material that is meant to be extracted in order   to be used, the following should be appended to statement 5.2 (a) or   5.2 (b):      "other than to extract section XX as-is for separate use."   Notice 5.2(a) is used if the Contributor intends for the IETF   Contribution to be published as an RFC.  Notice 5.2(b) is used along   with the Publication Limitation inSection 5.3 when the Contributor   does not intend for the IETF Contribution to be published as an RFC.   These notices may not be used with any standards-track document or   with most working group documents, except as discussed inSection 7.3   below, since the IETF must retain change control over its documents   and the ability to augment, clarify and enhance the original IETF   Contribution in accordance with the IETF Standards Process.   Notice 5.2(a) may be appropriate when republishing standards produced   by other (non-IETF) standards organizations, industry consortia or   companies.  These are typically published as Informational RFCs, and   do not require that change control be ceded to the IETF.  Basically,   documents of this type convey information for the Internet community.Bradner                  Best Current Practice                 [Page 10]

RFC 3667               IETF Rights in Submissions          February 2004   A fuller discussion of the rationale behind these requirements is   contained inSection 7.3 below.5.3.  Publication Limitation   If the Contributor only wants the IETF Contribution to be made   available in an Internet-Draft (i.e., does not want the IETF   Contribution to be published as an RFC) then the Contributor may   include the following notice in the Status of Memo section of the   Internet-Draft.      "This document may only be posted in an Internet-Draft."   This notice can be used on IETF Contributions that are intended to   provide background information to educate and to facilitate   discussions within IETF working groups but are not intended to be   published as an RFCs.5.4.  Copyright Notice (required for all IETF Documents)   (Normally placed at the end of the IETF Document.)      "Copyright (C) The Internet Society (year).  This document is      subject to the rights, licenses and restrictions contained inBCP78, and except as set forth therein, the authors retain all their      rights."   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 the document is a republication of the work of   another standards organization.  Such exceptions must be approved on   an individual basis by the IAB.5.5.

RFC 3667               IETF Rights in Submissions          February 20045.6 Exceptions   Notwithstanding the provisions of thisSection 5, in certain limited   cases an abbreviated notice may be placed on certain types of   derivative works of IETF Documents in accordance with thisSection5.6.   a. in MIB modules, PIB modules and similar material commonly      extracted from IETF Documents, except for material that is being      placed under IANA maintenance, the following abbreviated notice      shall be included in the body of the material that will be      extracted in lieu of the notices otherwise required bySection 5:         "Copyright (C) The Internet Society <year> .  This version of         this MIB module is part of RFC XXXX; see the RFC itself for         full legal notices."      When the MIB or PIB module is the initial version of a module that      is to be maintained by the IANA, the following abbreviated notice      shall be included:         "Copyright (C) The Internet Society <year>.  The initial         version of this MIB module was published in RFC XXXX; for full         legal notices see the RFC itself.  Supplementary information         may be available onhttp://www.ietf.org/copyrights/ianamib.html."      For other types of components than "MIB", substitute "MIB module"      with an appropriate identifier.  In the case of MIB and PIB      modules this statement should be placed in the DESCRIPTION clause      of the MODULE-IDENTITY macro.      Variations of these abbreviated notices are not permitted except      in cases where the material to be extracted 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 organization.  Such variations must be approved      on an individual basis by the IAB.   b. short excerpts of IETF Documents presented in electronic help      systems, for example, the DESCRIPTION clauses for MIB variables,      do not need to include a copyright notice.Bradner                  Best Current Practice                 [Page 12]

RFC 3667               IETF Rights in Submissions          February 20046.  Notices and Rights Required in RFC Editor Contributions   Since the IETF acts as publisher of Internet Drafts, even for   Internet Drafts that are not intended to become part of the Standards   Process, the following are required in all such drafts to protect the   IETF and its processes.  The RFC Editor may require additional   notices.   a. An IPR Disclosure Acknowledgement, identical to that specified inSection 5.1.   b. One of the following two copyright release statements:      A. "By submitting this Internet-Draft, I accept the provisions ofSection 3 of RFC 3667."      B. "By submitting this Internet-Draft, I accept the provisions ofSection 4 of RFC 3667."7.  Exposition of Why These Procedures Are the Way They Are7.1.  Rights Granted in IETF Contributions   The IETF/ISOC 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 the IETF Contributions in the IETF   Standards Process while leaving all other rights with the authors.   The non-exclusive rights that the IETF needs are:   a. the right to publish the document   b. the right to let the document be freely reproduced in the formats      that the IETF publishes it in   c. the right to let third parties translate it into languages other      than English   d. except where explicitly excluded (seeSection 5.2), the right to      make derivative works within the IETF process.   e. the right to let third parties extract some logical parts, for      example MIB modules   The authors retain all other rights, but cannot withdraw the above   rights from the IETF/ISOC.Bradner                  Best Current Practice                 [Page 13]

RFC 3667               IETF Rights in Submissions          February 20047.2.  Rights to use Contributed Material   Because, under the laws of most countries and applicable   international treaties, copyright rights come into existence whenever   a work of authorship is created (but seeSection 8 below regarding   public domain documents), and IETF cannot make use of IETF   Contributions if it does not have sufficient rights with respect to   these copyright rights, 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.  Without this   assurance, IETF and its participants would run a greater risk of   liability to the owners of these rights.   To this end, IETF asks Contributors to give the assurances inSection3.4 above.  These assurances are requested, however, only to the   extent of the Contributor's reasonable and personal knowledge.  (SeeSection 1(l))7.3.  Right to Produce Derivative Works   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.   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 though that the IETF only requires   this right for the production of derivative works within the IETF   Standards Process.  The IETF does not need, nor does it obtain, the   right to let derivative works be created outside of the IETF   Standards Process other than as noted inSection 3.3 (E).   The right to produce derivative works 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 an IETF Contribution as a working group   document or otherwise work on it.  For non-working group IETF   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 IETF Contributions, before the   IESG will consider the Internet-Draft for publication.Bradner                  Best Current Practice                 [Page 14]

RFC 3667               IETF Rights in Submissions          February 2004   Occasionally a Contributor may not want to grant publication rights   or the right to produce derivative works before finding out if an   IETF Contribution has been accepted for development in the IETF   Standards Process.  In these cases the Contributor may include the   Derivative Works Limitation described inSection 5.2 and the   Publication Limitation described inSection 5.3 in their IETF   Contribution.  A working group can discuss the Internet-Draft 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 IETF   Contribution as an RFC has not yet been granted.  If the IETF   Contribution is accepted for development the Contributor must then   resubmit the IETF Contribution without the limitation notices before   a working group can formally adopt the IETF Contribution as a working   group document.   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 claim   that the IETF version is the "new version" of the organization's   technology. Organizations that feel this way can specify that an IETF   Contribution can be published with the other rights granted under   this document but may withhold the right to produce derivative works   other than translations.  The right to produce translations is   required before any IETF Contribution can be published as an RFC to   ensure the widest possible distribution of the material in RFCs.   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 IETF Contribution, as specified inSection 5.2, in order to   notify IETF participants about this restriction.Bradner                  Best Current Practice                 [Page 15]

RFC 3667               IETF Rights in Submissions          February 20047.4.  Rights to Use Trademarks   Contributors may wish to seek trademark or service mark protection on   any terms that are coined or used in their IETF Contributions.  IETF   makes no judgment about the validity of any such trademark rights.   However, the IETF requires each Contributor, under the licenses   described inSection 3.3 above, to grant IETF a perpetual license to   use any such trademarks or service marks solely in exercising its   rights to reproduce, publish and modify the IETF Contribution.  This   license does not authorize any IETF participant to use any trademark   or service mark in connection with any product or service offering,   but only in the context of IETF Documents and discussions.7.5.  Who Does This Apply To?   Rights and licenses granted to the IETF under this document are   granted to all individuals noted inSection 1(a), irrespective of   their employment or institutional affiliation.  However, these   licenses do not extend broadly to the employers, sponsors or   institutions of such individuals, nor do they authorize the   individuals to exercise any rights outside the specific context of   the IETF Standards Process.8.  Contributions Not Subject to Copyright   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 as 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, the IETF Standards Process and all IETF participants, and   also 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.9. Security Considerations   This memo relates to IETF process, not any particular technology.   There are security considerations when adopting any technology, but   there are no known issues of security with IETF Contribution rights   policies.Bradner                  Best Current Practice                 [Page 16]
