AVSR vs. MSFT: unpublicized activity

14 months ago I said “6,212,547 is likely more important than any of the other numbers above.”  It looks to me from http://portal.uspto.gov/external/portal/pair that June 5 of this year the U.S. PTO declared that patent invalid, i.e., mailed a final rejection to Avistar. However, this event seems to have gone unpublicized, and it looks like Avistar filed an appeal last week, so the story is not yet over. Avistar has reported other news, e.g., the appointing of a new CEO last month, but has been uncharacteristically silent on the Microsoft re-examination requests.
