Section 6.1.3 of BCP 79 discusses "IPR of Others", and says: 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@xxxxxxxx. Such a notice should be sent as soon as reasonably possible after the person realizes the connection. And the referenced section 6.6 says: 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. Encouraged != required. The wrinkle here - and why I think you're getting some odd answers to your questions - is that you're not being clear about what role the "someone else" you're talking about has in the IETF. If the "someone else" is not participating in the IETF, then there's no problem, other than possibly your own conscience. If the "someone else" is participating while meeting the disclosure requirements, then once again there's no problem since the disclosure has already been done and there's no need for you to repeat it. But if they are participating and not disclosing, then there's a big problem, and in that case it may indeed suck to be you. My advice in such cases would be to consult an attorney with substantive expertise in IP law as to what your obligations are. I do expect such cases to be quite rare though. Ned
