Taiwan Semiconductor Manufacturing Company Limited v.Advanced Integrated Circuit Process LLC
An email notifies the parties that Director Review requests have been filed for two IPRs involving a semiconductor process patent. The patent owner is limited to a 15‑page response with no new evidence, and the Director will decide on the review.
Innoscience America, Inc. et al. v.Infineon Technologies Austria AG
The PTAB denied Innoscience's petition to institute IPR against Infineon's 9,899,481 B2 patent covering compound semiconductor power components, finding no reasonable likelihood of success on any of the 17 challenged claims.

SanDisk and Longitude Flash have settled their dispute over U.S. Patent No. 11,456,365 and jointly moved to dismiss the pending IPR. The Board has not yet instituted the review, and the parties rely on statutory authority to terminate the proceeding pre‑institution.
Yangtze Memory Technologies Company, Ltd. et al. v.Micron Technology, Inc. et al.
Micron opposes Yangtze Memory’s request for Director Review of the PTAB’s denial to institute an IPR on a 3D NAND patent. The response argues the petitioner offers no statutory grounds, misstates parallel litigation, and has waived procedural challenges.
GLOBALFOUNDRIES Inc. et al. v.OAK IP LLC
The PTAB held that Samsung’s IPR against OAK IP’s 9,905,691 patent succeeded on five claims – claims 1‑4 and 13 were found unpatentable – while the remaining claims survived.
GLOBALFOUNDRIES Inc. et al. v.OAK IP LLC
Globalfoundries and OAK IP settled their IPR dispute over U.S. Patent 9,905,691 before the Board instituted a trial. The settlement agreement was treated as confidential business information, and the proceeding was terminated.
GLOBALFOUNDRIES Inc. et al. v.OAK IP LLC
GlobalFoundries and patent owner Oak IP have filed a joint motion to terminate IPR2025-01052 after reaching a settlement. The Board has not yet instituted the review, and the parties argue termination is appropriate under 35 U.S.C. §317.
Analog Devices, Inc. et al. v.Number 14 B.V.
Analog Devices has filed a petition to cancel Number 14 B.V.’s 7,812,665 op‑amp offset‑calibration patent, asserting that the claims are obvious over multiple prior‑art references. The petition also argues that discretionary denial is improper.
NXP USA, INC. et al. v.Redstone Logics LLC
NXP and Redstone Logics filed a joint motion to dismiss NXP as a co‑petitioner in IPR2025‑00485, citing an agreement in principle and statutory bars on further petitions. The Board’s authority to dismiss a co‑petitioner pre‑institution is argued, with no settlement‑agreement requirement.
Advanced Micro Devices, Inc. et al. v.XtreamEdge, Inc. et al.
AMD and Pensando have filed a petition for rehearing after the PTAB denied institution of an IPR on their FPGA patent. They contend that recent court delays and the cancellation of a Markman hearing render the Board's discretionary denial inappropriate.
Advanced Micro Devices, Inc. et al. v.XtreamEdge, Inc. et al.
AMD and Pensando have filed an IPR petition challenging 18 claims of U.S. Patent 10,985,943, which covers FPGA‑based programmable logic devices for data‑flow processing in servers. The petition asserts obviousness over six prior‑art references and argues against discretionary denial.
Arm Ltd et al. v.DAEDALUS PRIME LLC
MediaTek and Daedalus Prime have settled their IPR dispute and jointly filed a motion to keep the settlement agreement confidential under 35 U.S.C. §317(b). The Board is asked to restrict access to the agreement to federal agencies or parties with good cause.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
The PTAB denied Micron's IPR petition against Yangtze Memory because the patent owner had successfully filed a statutory disclaimer covering all challenged claims related to 3D memory devices.
Entegris, Inc. v.Inpria Corporation
Entegris and Inpria filed a joint request to keep their settlement agreement confidential under 35 U.S.C. § 317(b) and related regulations, arguing that disclosure would harm their business interests.

Micron's request for Director Review of IPR2024-00794 was dismissed after Yangtze Memory appealed the PTAB's Final Written Decision, leaving the Board without jurisdiction.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
The USPTO denied Micron Technology’s request for Director Review of the Final Written Decisions in three IPRs, including the case involving Yangtze Memory Technologies’ patent 10,950,623. The order affirms that the Director will not intervene.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron seeks a PTAB Director Review of Yangtze Memory’s patent (IPR2024-00794). The Director will decide on the request, and Yangtze may file a limited response within five business days.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
The PTAB issued a Final Written Decision finding that Claims 1 and 6 were unpatentable over prior art (Park), while the remaining claims were patentable. The Board clarified claim terms like 'formed in the BSG' to encompass both gate-first and gate-last embodiments, rejecting Petitioner’s obviousness arguments based on hindsight bias.
Texas Instruments Incorporated v.Greenthread, LLC
The PTAB granted Director Review of the Final Written Decisions in three IPRs involving Texas Instruments and Greenthread, vacated those decisions, and remanded the cases for further proceedings, citing abuse of discretion in denying discovery and striking claim‑construction orders.
Samsung Electronics Co., Ltd. et al. v.SiOnyx, LLC
Samsung has filed an IPR petition to cancel 79 claims of SiOnyx’s 10,224,359 image‑sensor patent, asserting that the claims are anticipated or obvious over Iida and other prior art. The petition also argues that a discretionary denial would be improper.
Mundra Solar PV Ltd. et al. v.Trina Solar Co. Ltd.
The PTAB issued a Final Written Decision finding that all 11 challenged claims of the solar cell patent were obvious over prior art references. The Board credited the petitioner's evidence, concluding that an ordinary artisan would have combined Chang and Jin to achieve the claimed isolation features with reasonable success.
Yangtze Memory Technologies Company, Ltd. v.Micron Technology, Inc. et al.
The PTAB granted a Director Review of the institution decision in Micron's IPR against Yangtze Memory, staying the proceedings while the Board reconsidered challenges related to foreign sovereign control and RPI disclosure.
Innoscience America, Inc. et al. v.Infineon Technologies Americas Corp.
Innoscience has filed an IPR petition seeking cancellation of all 16 claims of Infineon’s 8,264,003 GaN cascode patent, arguing that each claim is obvious over known prior‑art combinations. The petition also argues that discretionary denial is improper.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron submits an authorized response defending the PTAB's institution decision for its memory‑chip etching patent, arguing the Board properly evaluated the Nakajima, Tessariol, and Mushiga references. The Patent Owner's objections are portrayed as mischaracterizations of the prior art.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
The PTAB denied institution of an IPR for Micron against Yangtze Memory Technologies because the petitioner failed to show a reasonable likelihood of success on any remaining claims after several key claims were disclaimed.
Samsung Electronics Co., Ltd. et al. v.Netlist, Inc.
Netlist seeks Director Review to overturn the PTAB’s decision to institute an IPR against its memory‑controller patent, arguing a faulty claim construction and insufficient particularity in Samsung’s grounds.
MediaTek, Inc. et al. v.Redstone Logics LLC
MediaTek has filed an IPR petition seeking to invalidate 12 claims of Redstone Logics’ ’339 patent covering multi‑core processor voltage and clock management, arguing obviousness over several prior‑art references and urging the Board to institute the review.
