On the heels of the rescission of the Fintiv guidance memorandum, the U.S. Patent and Trademark Office has again reshaped the PTAB’s approach to discretionary denials. On March 26, 2025, the Acting Director issued a new memorandum that fundamentally changes how the PTAB will handle inter partes review and post grant review petitions

For anyone following the evolving admissibility standards for expert opinions relating to patent damages, the EcoFactor v. Google case is one to watch. In December 2024, the Federal Circuit granted Google’s petition for rehearing en banc to address the effect of amended Federal Rule of Evidence 702 and Daubert v. Merrell Dow Pharmaceuticals as they relate to admissibility of damages expert testimony—particularly when a per-unit royalty rate is derived from three allegedly comparable lump-sum licenses.

On February 28, 2025, the U.S. Patent and Trademark Office announced that it was rescinding a 2022 memorandum that provided guidance regarding the application of the Apple v. Fintiv decision to the Patent Trial and Appeal Board’s discretion to deny patent challenges with pending parallel district court litigation. The PTO has referred parties back to precedent for guidance including Apple Inc. v. Fintiv, Inc. Rescinding the 2022 memorandum also has the effect of effectively removing the proposed rules related to discretionary denial that were under consideration as recently as last year.
