· IPR2024-01104

patent Final Written Decision

Dr. Squatch, LLC v.The Procter & Gamble Company

· IPR2024-01173

· IPR2024-01469

The Final Written Decision found that most claims (1-7, 9-15, and 18-20) were unpatentable under § 103 based on prior art combinations. The Board affirmed the Petitioner's success in demonstrating obviousness over references like Chaimberg and Roberge for several claim groups. While some procedural issues regarding timeliness were resolved favorably for the Petitioner, the core finding was a rejection of broad claims due to anticipation and obviousness.

patent instituted
