Wilson Sonsini Goodrich & Rosati is pleased to present our 2022 PTAB Year in Review.

We begin with a review of 2022 petition filings and outcomes at the Patent Trial and Appeal Board (PTAB), and examine the effect of the decrease in discretionary denials on case institutions.

We then provide a summary of notable developments at the PTAB, including recent precedential and director review decisions.

We then explore important appellate decisions relating to PTAB trials.

Finally, we provide an analysis of PTAB merits rationales for denying institution.
