Takeaways from PTAB’s Precedential Decision on Prior Art Analysis for Post-AIA Patents
In March 2023, the Patent Trial and Appeal Board (Board) addressed in Penumbra, Inc. v. Rapidpulse, Inc., IPR2021-01466, Paper 34 (Mar. 10, 2023), a key issue in inter partes reviews: how to establish a reference patent as prior art based on the filing date of an earlier-filed application, such as a provisional. The Board held that the requirements of the Federal Circuit’s decision in Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375 (Fed. Cir. 2015), do not apply for post-America Invents Act (AIA) patents. Penumbra, IPR2021-01466, Paper 34 at 29-35. On November 15, 2023, U.S Patent and Trademark Office (USPTO) Director Kathi Vidal designated the Penumbra decision precedential. This article explores the evolution of the law on this issue.
