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.
6.1. 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 of Section 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 this Section 6. 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 of Section 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 this Section 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 in Section 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.
6.2.1. Timing of disclosure under Section 6.1.1
The IPR disclosure required pursuant to section 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 of Section 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 under Section 6.1.2
The IPR disclosure required pursuant to section 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 of Section 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.
6.3. How must a disclosure be made?
IPR disclosures are made by following the instructions at http://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 of Section 6.6 (and either Section 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.6.5. 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 Sections 6.1.1. 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.
