Taiwan Semiconductor Manufacturing Company, Ltd. et al. v.Marlin Semiconductor Ltd. et al.
TSMC and Apple have filed a petition to institute an IPR against Marlin Semiconductor’s ’747 patent covering FET manufacturing methods. They argue the claims are anticipated or obvious over multiple prior‑art references and that discretionary denial is unwarranted.
Advanced Micro Devices, Inc. v.Advanced Cluster Systems, Inc.
AMD filed a request for rehearing after the PTAB Deputy Director denied institution of its IPR, arguing that its Instinct™ AI chips are vital to U.S. national security and AI competitiveness. The petition seeks reversal of the denial and referral to a merits panel.
Advanced Micro Devices, Inc. v.Advanced Cluster Systems, Inc.
AMD’s petition for rehearing of the USPTO’s discretionary denial in IPR2025-00862 was denied. The Board upheld the original decision denying institution of the challenge against Advanced Cluster Systems’ patent.
Advanced Micro Devices, Inc. v.Advanced Cluster Systems, Inc.
AMD filed a request for rehearing after the PTAB Deputy Director denied institution of its IPR, arguing that its Instinct AI chips are vital to U.S. national security and public health. The petition seeks reversal of the denial and referral to a merits panel.
Taiwan Semiconductor Manufacturing Company Ltd. v.Advanced Integrated Circuit Process LLC
The USPTO Director denied TSMC's request for review of the office's refusal to institute five IPRs against Advanced Integrated Circuit Process patents, leaving the institution decisions unchanged.
Taiwan Semiconductor Manufacturing Company Ltd. v.Advanced Integrated Circuit Process LLC
TSMC’s request for a Director‑review of an inter‑ partes review was denied, leaving Advanced Integrated Circuit Process’s semiconductor process patent intact. The Board affirmed the Director’s discretionary denial based on lack of persuasive justification and potential duplication with district‑court litigation.
Taiwan Semiconductor Manufacturing Company Ltd. v.Advanced Integrated Circuit Process LLC
Exhibit 1106 compiles PTAB final decision outcomes for TSMC, highlighting that many of its IPRs resulted in all claims being deemed unpatentable.
