SCOTUS to Decide: Is PTAB Required to Determine Patentability of All Claims Challenged in an IPR Petition?

Authored by Brian S. Mudge and Clifford A. Ulrich

On May 22, 2017, the United States Supreme Court granted certiorari in SAS Institute, Inc. v.

The case may significantly affect how the PTAB handles IPR proceedings.

PTAB Nixes Reliance on Technical Report: Not Publication

Authored by Brian Mudge

We have previously written about disputes regarding whether a prior art reference qualifies as a publication in AIA trials.[1] In a recent decision, the Board ruled that a prior art reference did not qualify as a publication under §102(a). The case, Activision Blizzard v Acceleration Bay,[2] rejected petitioner’s attempt to rely on a 1999 technical report allegedly published by University of California / San Diego (“UCSD”).

Key Takeaway:  This case demonstrates that the PTAB will adhere to demanding requirements for petitioners to establish that a reference qualifies as a prior art publication. Petitioners should be prepared to provide detailed evidence showing a prior art reference was publicly accessible before the priority date of a challenged patent. Meanwhile, patent owners should take advantage of opportunities to challenge the public accessibility of references, particularly where the evidence and arguments in a petition are conclusory; such challenges can be effective in a preliminary response and may derail a case before trial is instituted.
