Prior art of what exactly?

I didn't have the time to read all postings since the San Diego meeting, and I still don't know what exactly Microsoft claims to have a patent on.

If there is a precise description then we know what to look for in the archives.


That's the problem - there isn't a precise description and the Microsoft lawyers might even be right on this one - they don't know what they can claim until the Patent office actually gives them a decision. Although, they could let us know what they are trying to claim but then it would defeat the whole purpose of filing the patent application in secret?

The relevant question to us here, is whether the IPR issue will affect deployment. Part of it is whether we should ignore the IPR claims all together if they appear to be meaningless. In RFC 3669, section 4.6 examples are given of IPR claims that were choosen to be ignored by the WG because they were frivilous. The best quote is this part which in light of previous posting referencing the ASRG list might be relevant:

------------------------------------------------------------------------------
   In another case, patent claims were asserted that appeared to be
   derived from working group discussion, rather than vice versa (or
   independent discovery).  The claimants were known to be following the
   working group's work when the ideas were proposed, and their patent
   filing was considerably subsequent to that time.
