maybe it IS over?
I first encountered the ‘547 patent, “UTP based video and data conferencing” in 2004, when Avistar was challenging Polycom, and I asserted then that ‘547 should not have been granted. Three years ago, Microsoft filed for ex parte re-examination of ‘547. I speculated that ‘547 would not survive re-examination.
Last week, the U.S. PTO Board of Patent Appeals and Interferences issued a decision on appeal, affirming in part the examiner’s final rejection of all claims of ‘547.
Intellectual Ventures can appeal further, but maybe they will not.
From the decision’s conclusion:
“The Examiner established that the combination of Ensor, Ahuja ’88, Ahuja ’90, and known prior art renders obvious:
1. separate data and video paths arranged over unshielded twisted pair (UTP) wires as required by claim 1;
2. the limitations as required by claims 4 and 5; and
3. a combined mosaic video image as required by claim 10.
“The Examiner did not establish that the combination renders obvious:
4. a system capable of the transporting audio and visual (AV) signals over a UPT (sic) AV path and reproducing spoken audio and visual images based on the AV signals, as required by claim 11.”
