The Federal Circuit has closed the courthouse doors on the second wave of challenges to the USPTO's restrictive new IPR institution policies. In four orders issued December 8-9, 2025, the same three-judge panel (Judges Prost, Chen, and Hughes) denied mandamus petitions from Cambridge Industries, SanDisk, Western Digital, HighLevel, and Inari Agriculture, each seeking to challenge discretionary denials of inter partes review institution.

This week, U.S. Patent and Trademark Office (USPTO) Acting Director Coke Morgan Stewart posted another round of Director Discretionary Denial decisions to the PTAB Decisions page, almost all of which denied institution to America Invents Acts (AIA) patent validity trials. Stewart's recent rulings generally confirm the trend so far that a patent owner's settled expectations with respect to patents that have been in force for six years or more hold significant weight, although in two cases this trend was bucked.
