The 'possible royalty/fee' in some the of IPR disclosures is unacceptable for my applications. After a rather time consuming review my team has advised that I do not need to be concerned about the currently disclosed non-RF patents but we were unsure about undisclosed applications. Fortunately the majority of the codec components have been disclosed to the public for many years in earlier drafts and open source releases by the draft authors. I assume that the closed source usage of these components goes back even further. Can the authors of the draft please indicate when the major components of the codec were first offered to the public, in any form, so we can better gauge the risk of substantial components being covered by undisclosed applications? If there are any royalty bearing components in the codec they must be removed if the the codec is to be usable for me. Unfortunately, the Huawei disclosures are so vague that they can hardly be considered disclosures because they claim unpublished applications but do not specify the subject matter. These were only reported long after the last call on the draft which might complicate removing anything in response to them. With such late and non-specific disclosures how are we to express our preference to avoid non-RF encumbered technologies? I have audited the entire WG discussion archives, meeting minutes and source code repositories and was not able to find any technical contributions by anyone from Huawei. I assume that the IETF policy does not permit working group participants to follow the working group and secretly patent the working group's inventions as their own? It would be helpful if anyone here is aware that their specific technical contributions will be covered by currently undisclosed applications which may not have royalty free licensing if they would point them out to the group so that we can decide if we should remove those parts. I did notice one potentially important discrepancy. There are many more authors of the draft which are not are listed on it as authors. Are these people treated equally to the listed authors in terms of the IETF IPR disclosure requirements? I believe some of them have never posted to this list although I may have failed to match some of the names. +- Descriptive text ---------------------+ | Author Lines Pct Msg| +----------------------------------------+ |Timothy B.
