Distribution of this memo is unlimited.Copyright Notice   Copyright (C) The Internet Society (2005).Abstract   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 about any IPR constraints on a technical proposal as   possible.  The policies are also intended to benefit the Internet   community and the public at large, while respecting the legitimate   rights of IPR holders.  This memo 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.   This memo updatesRFC 2026 and, withRFC 3978, replacesSection 10 of   RFC 2026.  This memo also updates paragraph 4 of Section 3.2 ofRFC2028, for all purposes, including reference [2] inRFC 2418.Table of Contents1.

Definitions   The following definitions are for terms used in the context of this   document.  Other terms, including "IESG," "ISOC," "IAB," and "RFC   Editor," are defined in [RFC2028].   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 3979                 IP in IETF Technology                March 2005      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[RFC2026] 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 [RFC2026] 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 or RFC Editor ContributionsBradner                  Best Current Practice                  [Page 3]

RFC 3979                 IP in IETF Technology                March 2005   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.   m. "Implementing Technology": means a technology that implements an      IETF specification or standard.   n. "Covers" or "Covered" mean that a valid claim of a patent or a      patent application in any jurisdiction or a protected claim, 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.   o. "IPR" or "Intellectual Property Rights": means patent, copyright,      utility model, invention registration, database and data rights      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.2.  Introduction   In the years sinceRFC 2026 was published there have been a number of   times when the exact intent ofSection 10, the section which deals   with IPR disclosures has been the subject of vigorous debate within   the IETF community.  This is because it is becoming increasingly   common for IETF working groups to have to deal with claims of   Intellectual Property Rights (IPR), such as patent rights, with   regards to technology under discussion in working groups.  The aim of   this document is to clarify various ambiguities inSection 10 of   [RFC2026] that led to these debates and to amplify the policy in   order to clarify what the IETF is, or should be, doing.Bradner                  Best Current Practice                  [Page 4]

RFC 3979                 IP in IETF Technology                March 2005   IPR disclosures can come at any point in the IETF Standards Process,   e.g., before the first Internet-Draft has been submitted, prior to   RFC publication, or after an RFC has been published and the working   group has been closed down; they can come from people submitting   technical proposals as Internet-Drafts, on mailing lists or at   meetings, from other people participating in the working group or   from third parties who find out that the work is going or has gone   on; and they can be based on granted patents or on patent   applications, and in some cases be disingenuous, i.e., made to affect   the IETF Standards Process rather than to inform.RFC 2026, Section 10 established three basic principles regarding the   IETF dealing with claims of Intellectual Property Rights:   (a) the IETF will make no determination about the validity of any       particular IPR claim   (b) 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   (c) in order for the 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 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       participants, that is reasonably and personally known to the       participant.  No patent search is required.Section 1 defines the terms used in this document.  Sections3,4 and   5 of this document address the intellectual property issues   previously addressed bySection 10 of RFC 2026.  Sections6 thru 12   then explain the rationale for these provisions, including some of   the clarifications that have been made since the adoption ofRFC2026.  The rules and procedures set out in this document are not   intended to modify or alter the IETF's current policy toward IPR in   the context of the IETF Standards Process.  They are intended to   clarify and fill in procedural gaps.   A companion document [RFC3978] deals with rights (such as copyrights   and trademarks) in Contributions, including the right of IETF and its   participants to publish and create derivative works of those   Contributions.  This document is not intended to address those   issues.Bradner                  Best Current Practice                  [Page 5]

RFC 3979                 IP in IETF Technology                March 2005   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.  Contributions to the IETF3.1.  General Policy   In all matters of Intellectual Property Rights, the intent is to   benefit the Internet community and the public at large, while   respecting the legitimate rights of others.3.2.  Rights and Permissions3.2.1.  All Contributions   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.   A. The Contributor represents that he or she has made or will      promptly make all disclosures required bySection 6.1.1 of this      document.   B. The 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.   C. If the Contribution is an Internet-Draft, this agreement must be      acknowledged, by including in the "Status of this Memo" section on      the first page of the Contribution, the appropriate notices      described inSection 5 of [RFC3978].4.  Actions for Documents for which IPR Disclosure(s) Have Been Received   (A) When any Intellectual Property Right is disclosed before       publication as an  RFC, with respect to any technology or       specification, described in a Contribution in the manner set       forth inSection 6 of this document, the RFC Editor shall ensure       that the document include a note indicating the existence of such       claimed Intellectual Property Rights in any RFC published from       the Contribution.  (SeeSection 5 below.)Bradner                  Best Current Practice                  [Page 6]

RFC 3979                 IP in IETF Technology                March 2005   (B) The IESG disclaims 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 claims.   (C) Where Intellectual Property Rights have been disclosed for IETF       Documents as provided inSection 6 of this document, the IETF       Executive Director shall request from the discloser of such IPR,       a written assurance that upon approval by the IESG for       publication as RFCs 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 Implementing       Technology under one of the licensing options specified inSection 6.5 below unless such a statement has already been       submitted.  The working group proposing the use of the technology       with respect to which the Intellectual Property Rights are       disclosed may assist the IETF Executive Director 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 Executive Director, and be made available       online.4.1.  No Determination of Reasonable and Non-discriminatory Terms   The IESG will not make any explicit determination that the assurance   of reasonable and non-discriminatory terms or any other terms for the   use of an Implementing Technology has been fulfilled in practice.  It   will instead apply the normal requirements for the advancement of   Internet Standards.  If the two unrelated implementations of the   specification that are required to advance from Proposed Standard to   Draft Standard have been produced by different organizations or   individuals, or if the "significant implementation and successful   operational experience" required to advance from Draft Standard to   Standard has been achieved, the IESG will presume that the terms are   reasonable and to some degree non-discriminatory.  (SeeRFC 2026,   Section 4.1.3.) 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.Bradner                  Best Current Practice                  [Page 7]

RFC 3979                 IP in IETF Technology                March 20055.  Notice to be Included in RFCs   The RFC Editor will ensure that the following notice is present in   all IETF RFCs and all other RFCs for which an IPR disclosure or   assertion has been received prior to publication.   Disclaimer of validity:      "The IETF 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 this 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.  Information on the procedures with respect to rights      in RFC documents can be found inBCP 78 andBCP 79.      Copies of IPR 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      athttp://www.ietf.org/ipr.      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 this standard.  Please address the information to the      IETF at ietf-ipr@ietf.org."6.  IPR Disclosures   This section discusses aspects of obligations associated with IPR   disclosure.   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 or the   participant's employer or sponsor makes an appropriate disclosure in   place of the participant doing so.Bradner                  Best Current Practice                  [Page 8]

RFC 3979                 IP in IETF Technology                March 20056.1.  Who Must Make an IPR Disclosure?6.1.1.  A Contributor's IPR in his or her Contribution   Any Contributor who reasonably and personally knows of IPR meeting   the conditions ofSection 6.6 which the Contributor believes Covers   or may ultimately Cover his or her Contribution, or which the   Contributor reasonably and personally knows his or her employer or   sponsor may assert against Implementing Technologies based on such   Contribution, must make a disclosure in accordance with thisSection6.   This requirement specifically includes Contributions that are made by   any means including electronic or spoken comments, unless the latter   are rejected from consideration before a disclosure could reasonably   be submitted.  An IPR discloser is requested to withdraw a previous   disclosure if a revised Contribution negates the previous IPR   disclosure, or to amend a previous disclosure if a revised   Contribution substantially alters the previous disclosure.   Contributors must disclose IPR meeting the description in this   section; there are no exceptions to this rule.6.1.2.  An IETF Participant's IPR in Contributions by Others   Any individual participating in an IETF discussion who reasonably and   personally knows of IPR meeting the conditions ofSection 6.6 which   the individual believes Covers or may ultimately Cover a Contribution   made by another person, or which such IETF participant reasonably and   personally knows his or her employer or sponsor may assert against   Implementing Technologies based on such Contribution, must make a   disclosure in accordance with thisSection 6.6.1.3.  IPR of Others   If a person has information about IPR that may Cover IETF   Contributions, but the participant is not required to disclose   because they do not meet the criteria inSection 6.6 (e.g., the IPR   is owned by some other company), such person is encouraged to notify   the IETF by sending an email message to ietf-ipr@ietf.org.  Such a   notice should be sent as soon as reasonably possible after the person   realizes the connection.6.2.  The Timing of Providing Disclosure   Timely IPR disclosure is important because working groups need to   have as much information as they can while they are evaluating   alternative solutions.Bradner                  Best Current Practice                  [Page 9]

RFC 3979                 IP in IETF Technology                March 20056.2.1.  Timing of Disclosure UnderSection 6.1.1   The IPR disclosure required pursuant tosection 6.1.1 must be made as   soon as reasonably possible after the Contribution is published in an   Internet Draft unless the required disclosure is already on file.   For example, if the Contribution is an update to a Contribution for   which an IPR disclosure has already been made and the applicability   of the disclosure is not changed by the new Contribution, then no new   disclosure is required.  But if the Contribution is a new one, or is   one that changes an existing Contribution such that the revised   Contribution is no longer Covered by the disclosed IPR or would be   Covered by new or different IPR, then a disclosure must be made.   If a Contributor first learns of IPR in its Contribution that meets   the conditions ofSection 6.6, 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.   Participants who realize that a Contribution will be or has been   incorporated into a submission to be published in an Internet Draft,   or is seriously being discussed in a working group, are strongly   encouraged to make at least a preliminary disclosure.  That   disclosure should be made as soon after coming to the realization as   reasonably possible, not waiting until the document is actually   posted or ready for posting.6.2.2.  Timing of Disclosure UnderSection 6.1.2   The IPR disclosure required pursuant tosection 6.1.2 must be made as   soon as reasonably possible after the Contribution is published in an   Internet Draft or RFC, unless the required disclosure is already on   file.  Participants who realize that the IPR will be or has been   incorporated into a submission to be published in an Internet Draft,   or is seriously being discussed in a working group, are strongly   encouraged to make at least a preliminary disclosure.  That   disclosure should be made as soon after coming to the realization as   reasonably possible, not waiting until the document is actually   posted or ready for posting.   If a participant first learns of IPR that meets the conditions ofSection 6.6 in 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 was published in an Internet-Draft   or RFC, a disclosure must be made as soon as reasonably possible   after the IPR becomes reasonably and personally known to the   participant.Bradner                  Best Current Practice                 [Page 10]

RFC 3979                 IP in IETF Technology                March 20056.3.  How Must a Disclosure be Made?   IPR disclosures are made by following the instructions athttp://www.ietf.org/ipr-instructions.6.4.  What Must be in a Disclosure?6.4.1.  The disclosure must list the numbers of any issued patents or   published patent applications or indicate that the claim is based on   unpublished patent applications.  The disclosure must also list the   specific IETF or RFC Editor Document(s) or activity affected.  If the   IETF Document is an Internet-Draft, it must be referenced by specific   version number.  In addition, if the IETF Document includes multiple   parts and it is not reasonably apparent which part of such IETF   Document is alleged to be Covered by the IPR in question, it is   helpful if the discloser identifies the sections of the IETF Document   that are alleged to be so Covered.6.4.2.  If a disclosure was made on the basis of a patent application   (either published or unpublished), then, if requested to do so by the   IESG or by a working group chair, the IETF Executive Director can   request a new disclosure indicating whether any of the following has   occurred: the publication of a previously unpublished patent   application, the abandonment of the application and/or the issuance   of a patent thereon.  If the patent has issued, then the new   disclosure must include the patent number and, if the claims of the   granted patent differ from those of the application in manner   material to the relevant Contribution, it is helpful if such a   disclosure describes any differences in applicability to the   Contribution.  If the patent application was abandoned, then the new   disclosure must explicitly withdraw any earlier disclosures based on   the application.   New or revised disclosures may be made voluntarily at any time.6.4.3.  The requirement for an IPR disclosure is not satisfied by the   submission of a blanket statement of possible IPR on every   Contribution.  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 to license   all potential IPR under fair 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 willingness   to license all of its potential IPR meeting the requirements ofSection 6.6 (and eitherSection 6.1.1 or 6.1.2) to implementers of an   IETF specification on a royalty-free basis as long as any other terms   and conditions are disclosed in the IPR disclosure statement.Bradner                  Best Current Practice                 [Page 11]

What Licensing Information to Detail in a 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 RFCs 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.   The inclusion of licensing information in IPR disclosures 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 licensing information in an IPR disclosure would   significantly delay its submission it is quite reasonable to submit a   disclosure without licensing information and then submit a new   disclosure when the licensing information becomes available.6.6.  When is a Disclosure Required?   IPR disclosures under Sections6.1.1. and 6.1.2 are required with   respect to IPR that is owned directly or indirectly, by the   individual or his/her employer or sponsor (if any) or that such   persons otherwise have the right to license or assert.7.  Failure to Disclose   There are cases where 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 submitting documents or participating in IETF discussions,   a person who does not 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 to be Covered by IPR which he or she will not disclose.   Contributing to or participating in IETF discussions about a   technology without making required IPR disclosures is a violation of   IETF process.Bradner                  Best Current Practice                 [Page 12]

RFC 3979                 IP in IETF Technology                March 20058.  Evaluating Alternative Technologies in IETF Working Groups   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.  But IETF working groups have the discretion   to adopt technology with a commitment of fair and non-discriminatory   terms, or even with no licensing commitment, 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.   Over the last few years the IETF 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 unless there is a very good reason   to do so.  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 is not   the same thing as the knowledge that there will be no IPR claims in   the future.  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 also be noted that the validity and enforceability of any   IPR may be challenged for legitimate reasons, and the mere existence   of an IPR disclosure should not automatically be taken to mean that   the disclosed IPR is valid or enforceable.  Although the IETF can   make no actual determination of validity, enforceability or   applicability of any particular IPR claim, it is reasonable that a   working group will take into account on their own opinions of the   validity, enforceability or applicability of Intellectual Property   Rights in their evaluation of alternative technologies.Bradner                  Best Current Practice                 [Page 13]

RFC 3979                 IP in IETF Technology                March 20059.  Change Control for 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.10.  Licensing Requirements to Advance Standards Track IETF DocumentsRFC 2026 Section 4.1.2 states: "If patented or otherwise controlled   technology is required for implementation, the separate   implementations must also have resulted from separate exercise of the   licensing process."  A key word in this text is "required."  The mere   existence of disclosed IPR does not necessarily mean that licenses   are actually required in order to implement the technology.Section4.1 of this document should be taken to apply to the case where there   are multiple implementations and none of the implementers have felt   that they needed to license the technology and they have no plausible   indications that any IPR holder(s) will try to enforce their IPR.11.  No IPR Disclosures in IETF Documents   IETF and RFC Editor Documents must not contain any mention of   specific IPR.  All specific IPR disclosures must be submitted as   described inSection 6.  Specific IPR disclosures must not be in the   affected IETF and RFC Editor Documents because the reader could be   misled.  The inclusion of a particular IPR disclosure in a document   could be interpreted to mean that the IETF, IESG, or RFC Editor has   formed an opinion on the validity, enforceability, or applicability   of the IPR.  The reader could also be misled to think that the   included IPR disclosures are the only IPR disclosures the IETF has   received concerning the IETF document.  Readers should always refer   to the on-line web page to get a full list of IPR disclosures   received by the IETF concerning any Contribution.

There are security considerations when adopting any technology,   whether IPR-protected or not.  A working group should take those   security considerations into account as one part of evaluating the   technology, just as IPR is one part, but there are no known issues of   security with IPR procedures.13.
