Yangtze Memory Technologies Company, Ltd. et al. v.Micron Technology, Inc. et al.
Micron successfully opposes Yangtze Memory’s request for Director Review of a PTAB decision denying institution of an IPR on its 3D NAND patent. The Board finds Yangtze’s arguments unsubstantiated and denies the review.
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.
NXP Semiconductors N .V. et al. v.Harbor Island Dynamic, LLC
NXP Semiconductors has filed an IPR petition seeking cancellation of all 19 claims of Harbor Island Dynamic’s ’886 patent, asserting anticipation and obviousness over Okashita, Yu, and Burgener references.

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.
NXP USA, INC. et al. v.Redstone Logics LLC
