PTAB Ends IPR2025-01188 After Post-Institution Settlement

In IPR2025-01188, the Patent Trial and Appeal Board terminated the proceeding after the parties settled following institution. The decision applies the familiar framework of 35 U.S.C. § 317 and 37 C.F.R. § 42.74, which govern settlement and termination of inter partes review, but it is still a useful reminder of how the Board handles cases once trial is already underway.

The core ruling is straightforward: when the parties jointly request termination after institution and the Board has not yet decided the merits, the PTAB generally will terminate the review as to those parties.

PTAB Issues Scheduling Order in IPR2026-00094: Key Deadlines and Practice Implications

The Patent Trial and Appeal Board’s April 13, 2026 scheduling order in IPR2026-00094 is procedural rather than merits-driven, but it still deserves attention from PTAB practitioners.

At a high level, the Board’s order establishes the case schedule that will govern the parties through trial.
