  • PTAB to Adjust Attorney Client Privilege Rule Privilege Expanded to Cover Communications with Foreign Agents  Tomorrow's Federal Register will include a NPRM to amend the rules of practice before the Patent Trial and Appeal Board (PTAB).

  • New PTAB Evidence Option Not Moving the Needle So Far Preliminary Responses Accompanied by Declaration Evidence: Early Results   Back on May 1st, the Patent Trial & Appeal Board (PTAB) began to accept new testimonial evidence with patentee preliminary responses.  The PTAB implemented this change to address complaints that patentees were disadvantaged by previous rules precluding such evidence from accompanying a preliminary response to the petition.

On the other hand, 93% of... More
  • PTAB Clarifies Weight of Claimed Condition Precedent Common USPTO Debate Clarified by New Precedential Decision Ex parte Schulhauser  A common debate at the PTO in recent years at both the examination and Board level has been the appropriate treatment of a claimed condition precedent.  That is, if a claim recites that certain functionality only occurs on certain conditions, does that alternate functionality constrain the broadest reasonable scope of the claim?    In Ex parte Schulhauser (here) the Board makes clear that the answer to this question may depend on...
