Micron’s attempt to overturn a DRAM‑related patent is rebuffed as the PTAB finds its Director Review requests introduce prohibited new evidence and deceptive arguments. Patent Owner urges denial of the requests.
Micron Technology Inc. et al. v.Palisade Technologies, LLP
Micron has filed a petition for Director Review after the PTAB denied institution of its IPR against Palisade’s DRAM patent. The petition stresses examiner error, misuse of settled‑expectations doctrine, and critical national‑security implications of Micron’s domestic memory‑chip expansion.
Micron Technology Inc. et al. v.Palisade Technologies, LLP
An email informs Micron and Palisade that a Director Review has been requested for IPR2025-01008 (and 01009). The patent owner may file a limited response within five business days, with no new evidence allowed, and the Director will decide on the request.
GLOBALFOUNDRIES Inc. et al. v.OAK IP LLC
The PTAB held that Samsung Electronics’ challenge to Acorn Semi’s ’261 patent succeeded, finding all nine challenged claims unpatentable based on anticipation by Grupp ’483 and obviousness over Jammy.
GLOBALFOUNDRIES Inc. et al. v.OAK IP LLC
GlobalFoundries and Oak IP filed a joint motion to terminate IPR2025-00889 after reaching a settlement, citing that the Board has not yet instituted the review and all disputes are resolved.
GLOBALFOUNDRIES Inc. et al. v.OAK IP LLC
Globalfoundries and Oak IP settled their IPR dispute before the Board instituted a trial. The Board granted the joint motion to terminate and treated the settlement agreement as confidential.
Samsung Electronics Co., Ltd. et al. v.Radian Memory Systems LLC
Samsung Electronics and Radian Memory Systems settled their IPR dispute (IPR2025-01378) before trial. The Board granted the joint motion to terminate and kept the settlement documents confidential.
Intel Corporation et al. v.Advanced Cluster Systems, Inc.
AMD and Intel jointly request that their settlement with Advanced Cluster Systems be kept confidential under 35 U.S.C. §317(b). The motion cites statutory authority to treat the agreement as business confidential information.
Intel Corporation et al. v.Advanced Cluster Systems, Inc.
Intel and AMD have filed a joint motion to terminate IPR2025-00916 after reaching a settlement with patent owner Advanced Cluster Systems. The motion cites statutory authority and argues that termination conserves resources and supports settlement policy.
uPI Semiconductor Inc. v.Force MOS Technology Co. Ltd.
Force MOS Technology seeks Director review of a PTAB decision that found claims 1 and 3‑5 of its power MOSFET patent unpatentable. The Patent Owner contends the Board created new arguments, misapplied Fintiv guidance, and violated due‑process rights, urging reversal.
Taiwan Semiconductor Manufacturing Company, Ltd. et al. v.Marlin Semiconductor Ltd. et al.
TSMC seeks Director review of a denied institution decision, arguing that the ’747 patent was erroneously issued and threatens U.S. national‑security‑critical chip production. The petition highlights material examiner errors, lack of settled expectations by the patent owner, and the impact of the 2025 government shutdown on the Fintiv analysis.
Taiwan Semiconductor Manufacturing Company Limited et al. v.Marlin Semiconductor Ltd. et al.
The USPTO denied Director Review requests for four IPR institution decisions, including the challenge to Patent 9,093,473 owned by Marlin Semiconductor. Petitioners Taiwan Semiconductor and Apple’s bid to overturn the institution denial was rejected.
Taiwan Semiconductor Manufacturing Company Limited et al. v.Marlin Semiconductor Ltd. et al.

TSMC seeks PTAB reversal of a Director’s discretionary denial of an IPR against its 28nm‑3nm process patents, arguing national‑security stakes, settled expectations, and material examiner errors. The petition cites extensive prior art to show lack of patentability under §§102 and 103.
Taiwan Semiconductor Manufacturing Company Ltd. v.Advanced Integrated Circuit Process LLC
Advanced Integrated Circuit Process LLC opposes Taiwan Semiconductor Manufacturing Co.'s request for a Director review of U.S. Patent 7,579,227, arguing the Board correctly exercised discretionary denial.
