Advanced Micro Devices, Inc. et al. v.Concurrent Ventures, LLC et al.
Patent owners seek rehearing to overturn the PTAB's denial of discretionary denial, arguing that a June 2026 trial in the parallel district court precedes the PTAB's final decision deadline, invoking Fintiv factors. They reference a prior Director decision in a related IPR that denied institution under similar circumstances.
Advanced Micro Devices, Inc. et al. v.Concurrent Ventures, LLC et al.
The USPTO Director has initiated a sua sponte review of three IPR institution decisions after the Patent Owner claimed the Petitioners violated a Sotera stipulation by litigating the same invalidity issues in district court. The parties may file brief arguments, and the proceedings are stayed pending the Director’s opinion.
Infineon Technologies Americas Corp. et al. v.MOSAID Technologies Inc.
MOSAID Technologies has filed a Director review request challenging the PTAB’s decision to institute an IPR against its 7,051,306 patent. The request contends that Infineon’s petition inconsistently handles claim constructions already litigated in district court, violating Board guidance and warranting reversal of the institution.
Infineon Technologies Americas Corp. et al. v.MOSAID Technologies Inc.
Infineon contests MOSAID’s late Director Review request, asserting that claim‑construction issues were disclosed before the IPR petition and can be reconciled with district‑court constructions. The petitioner offers stipulations to avoid any inconsistent outcomes.
Infineon Technologies Americas Corp. et al. v.MOSAID Technologies Inc.
Infineon has filed an IPR petition challenging all 51 claims of MOSAID’s ’306 power‑management patent. The challenger argues the claims are obvious over a suite of prior‑art references covering power islands and dynamic voltage/frequency scaling. The petition follows a prior IPR that was instituted and later terminated.
United Microelectronics Corporation et al. v.Advanced Integrated Circuit Process LLC
United Microelectronics Corp. (UMC) has filed an IPR petition challenging six claims of Advanced Integrated Circuit Process LLC's 8,198,686 patent, asserting obviousness over Aoyama, Akasaka, and Hsu823 prior art.
Western Digital Technologies et al. v.Godo Kaisha IP Bridge 1
Western Digital Technologies, Inc.'s IPR petition against patent number 10367138 was denied by the PTAB. The Board found that Petitioner failed to establish a reasonable likelihood of success on the merits under Section 103 grounds.

The USPTO denied Micron's request for Director Review of the institution denial in IPR2025-01008, leaving the original denial in place.
Micron Technology Inc. et al. v.Palisade Technologies, LLP
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.
