Except that the additional grant explicitly requires that: "redistributed modified works do not contain misleading author, version, name of work, or endorsement information." And my understanding is that the sort of misrepresentations which you suggest are already well protected against in established law. So I don't think that this would weaken the IETF's position in the event of such a thing happening, and I'm not aware of any such problem occurring with any of the RFCs that are already published containing such a grant. Similarly there exist other RFCs which already have external grants too, and there has been no hint of trouble or an inability to prevent it if it arose with those either, has there? If this clause becomes a blocker, then we should simply remove it, but in that case it would be good to have clear reasons why it became a blocker, since the things you say you fear here, I see as already being prohibited anyway. I agree with you that this is an entirely separate issue to the validity or other implications of any of the IPR claims though. But on that note, have you had any clarification from Huawei as to whether they believe their newly acquired patent actually does read on this technology? Last I had heard on that there was some doubt and they were still studying it? It would be nice to have them officially clear that up. Cheers, Ron
