I am aware that the last call period has ended, but maybe this comment will aid IESG processing of the document. After having talked to the SFLC and the FSF about the patent threat on this document, I no longer oppose publication of the tls-extractor document on the standards track. It appears as if the patent threat on the document (as I perceived it) was resolved when Certicom's agent clarified their intentions on the mailing list. Thanks to Pasi for nudging me to escalate the issue, and also thanks to the SFLC for giving me advice on the matter. Generally, it appears sub-optimal that implementers needs to review not only the patent disclosure page but also review mailing list archives to be able to evaluate the patent status on a document. Finally, I note that the time period a document is in IETF Last Call, even if the time window is extended as it was for tls-extractor, is too short to allow matters to be resolved that requires coordination between multiple organizations and feedback from legal people.
