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.
The U.S. Court of Appeals for the Federal Circuit (CAFC) ruled in a precedential decision today that Medtronic, Inc. failed to show the challenged claims of five patents covering catheter technology unpatentable. The CAFC specifically upheld the Patent Trial and Appeal Board’s (PTAB’s) finding that the primary prior art reference cited by Medtronic did not qualify as prior art under pre-America Invents Act (AIA) first-to-invent provisions. Judge Dyk dissented, arguing that the prior art reference had been shown to qualify as prior art, and thus could support a determination of anticipation or obviousness.
Standard-documentation from online sources maintained by standard setting organizations (SSOs) is usually an important source of relevant prior art. Such prior art can include technical specifications, technical reports, change requests, liasioning statements, work item descriptions, study documents, recommendations and RFCs. However, accessing this documentation available in SSO websites is often not easy.
The Patent Trial and Appeal Board (PTAB) has the discretion to deny institution of an inter partes review (IPR) proceeding under 35 U.S.C. § 325(d) if “the same or substantially the same prior art or arguments previously were presented to the Office.” In Advanced Bionics, LLC v. Med-El Elektromedizinische Geräte GmbH (“Advanced Bionics”), the PTAB established a two-part framework for determining whether a PTAB panel should exercise discretion under Section 325(d). This article surveys recent PTAB decisions having the common fact that the IPR challenges rely upon prior art that is the same or substantially the same as prior art submitted in an IDS during prosecution to glean insights as to how parties and the Board are addressing Advanced Bionics in this scenario.
In Part I of this series, we discussed the importance of identifying and avoiding patentability-blocking ambiguities in a patent application. It is equally important that the patent application drafter bring a sensibility to the drafting of the application that recognizes that conceptually the application must not simply be seen as a document whose job is to describe an invention but must also be understood to be a document that must have a descriptive capability that enables it to distinguish patent worthy subject matter from prior art. Thus, when the patentability of patent worthy subject matter disclosed by the application is challenged, the application can speak—it is able to defend its patentability. This capability is essential in both pre and post grant forums.
