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 Director Review order grants Texas Instruments a remand, vacating the PTAB’s final decision. The Board is instructed to allow narrow discovery on privity and to consider previously excluded claim‑construction orders.
Texas Instruments Incorporated v.Greenthread, LLC
The PTAB granted Director Review of the Final Written Decisions in Texas Instruments’ IPRs against Greenthread, vacated those decisions, and remanded the cases for further proceedings, ordering new discovery on the privity issue.
Texas Instruments Incorporated v.Greenthread, LLC
Texas Instruments petitioned to challenge Greenthread’s semiconductor patent and sought joinder with a related IPR. The PTAB found a reasonable likelihood of unpatentability and granted both institution and joinder, merging the proceeding into IPR2023-01242.
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.
Samsung Electronics Co., Ltd. et al. v.SiOnyx, LLC
Samsung has filed an IPR petition seeking cancellation of all 18 claims of SiOnyx’s ’714 image‑sensor patent, alleging anticipation or obviousness over a suite of prior‑art references. The petition argues that the Board should not deny institution under §314(a).
Mundra Solar PV Ltd. et al. v.Trina Solar Co. Ltd.
The PTAB found all 17 challenged claims unpatentable under 35 U.S.C. § 103, concluding that the combination of prior art references was sufficient to teach the claimed solar cell structure. This decision validates the Petitioner's arguments regarding obviousness in photovoltaic technology.
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.
Micron has filed a Director Review request to overturn the PTAB’s institution of an IPR against its 3D NAND patent, arguing YMTC lacks standing and the Board should have exercised discretionary denial.
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.
Micron has filed an IPR petition challenging Yangtze Memory’s 3D NAND patent, asserting that the Nakajima reference makes the claims obvious under §103. The petition argues no discretionary denial applies and seeks institution of the review.
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.
Silicon Motion Inc. et al. v.K.Mizra Inc.
Silicon Motion and K.Mizra settled their IPR dispute over patent 10,331,379 before trial, leading the PTAB to terminate the proceeding and keep the settlement confidential.
Silicon Motion Inc. et al. v.K.Mizra Inc.
Silicon Motion and K.Mizra have settled their dispute over U.S. Patent 10,313,379 and jointly moved to terminate the inter partes review. The Board is expected to grant the termination.
Texas Instruments Incorporated v.Greenthread, LLC
The USPTO denied Texas Instruments' request for Director Review of the Final Written Decisions in two IPRs involving Greenthread's image‑sensor patent, leaving the original rulings intact.
Texas Instruments Incorporated v.Greenthread, LLC
The PTAB denied Texas Instruments' request for Director Review of the Final Written Decision in IPR2024-00774, upholding the earlier ruling against Greenthread's patent.
Texas Instruments Incorporated v.Greenthread, LLC
Texas Instruments challenges the validity of a patent covering CMOS device fabrication methods on grounds of obviousness (35 U.S.C. § 103). The petition asserts that the claimed graded dopant structures are anticipated or rendered obvious by various prior art combinations, including Kawagoe and Wieczorek.
Micron Technology, Inc. et al. v.Netlist, Inc.
Micron filed a petition for rehearing after the PTAB denied institution of its IPR against Netlist’s ’608 patent. The petitioner asserts the Board missed critical explanations of how the Osanai reference satisfies the claimed data‑path and delay‑circuit limitations.
Micron Technology, Inc. et al. v.Netlist, Inc.
Micron filed a Director Review request challenging the PTAB’s denial to institute its IPR against Netlist’s memory‑interface patent. The petition argues the Board misapplied General Plastic discretionary denial factors to a me‑too petition.
Micron Technology, Inc. et al. v.Netlist, Inc.
The USPTO denied Micron's request for Director Review of the decision that had previously denied institution of its IPR against Netlist's patent. The original institution denial therefore stands.
Micron Technology, Inc. et al. v.Netlist, Inc.
Micron Technology filed a Petition challenging 10268608's claims on grounds of obviousness (103). The petition asserts that the claimed memory module features are anticipated by combinations of prior art, including Hiraishi, Butt, Tokuhiro, Ellsberry, and Kim.
Western Digital Technologies, Inc. et al. v.Godo Kaisha IP Bridge 1
Western Digital Technologies successfully convinced the PTAB to institute review on 16 claims against Godo Kaisha IP Bridge 1's patent (11968909). The Board found sufficient support for obviousness over Bowen and Soukup, particularly regarding Claim 5.
Western Digital Technologies, Inc. et al. v.Godo Kaisha IP Bridge 1
Western Digital Technologies successfully convinced the PTAB that its claims against Godo Kaisha IP Bridge 1 were non-obvious, leading to the institution of trial on all claims. The Board found a reasonable likelihood of prevailing on Claim 1 based on combinations of Bowen and Sunai prior art.
