Re: [rtcweb] Unified plan IPR

The chairs have asked us not to cross-post. As this pertains to an IETF 
IPR declaration, I'll speak to it here.

I'll note that your response is a vast overreaction at this juncture, as 
(1) these are merely applications, not granted patents; and (2) Ericsson 
has not yet indicated their intentions regarding the licensing terms of 
any patents that may result.

In terms of your two questions: I'm not a laywer, so I'm not able to 
speak to the applicability of the patents in any authoritative fashion. 
All that I can really say is that I have a reasonable belief that the 
claims of these applications, if granted, would apply to the draft in 
question.

I will make one factual observation, without any interpretation, from 
which you can draw your own conclusions: the independent claims of the 
patent applications in question do not mention SDP.
