Detailed Summary
In IPR2025-00683, Taiwan Semiconductor Manufacturing Company Limited (TSMC) filed a Director Review request challenging the Patent Trial and Appeal Board’s discretionary denial to institute an inter partes review of U.S. Patent No. 8,907,425 owned by Advanced Integrated Circuit Process LLC. The patent owner submitted an authorized response asserting that the Director correctly exercised discretion under 37 C.F.R. § 42.71(c), that TSMC’s arguments on national security, settled expectations, and duplication lack evidentiary support, and that TSMC’s request fails to satisfy the procedural requirements of 37 C.F.R. § 42.71(d). The Board’s final decision on the review request has not yet been issued, leaving the matter unresolved.
