BMW has filed a petition to institute an IPR against Foras Technologies’ fault‑tolerant multiprocessor patent, arguing that the claims are obvious over Fox, Safford, Arai and related references.
BMW of North America, LLC et al. v.Foras Technologies Limited
The PTAB issued a Final Written Decision rejecting all claims of the '781 patent based on obviousness (35 U.S.C. § 103). The Board found that while prior art references describe processor swapping or task management, they fail to teach the specific transfer of the 'role' of boot processor during runtime as claimed.
Samsung Electronics Co., Ltd. et al. v.Netlist, Inc.
The PTAB held that Samsung’s challenge to Netlist’s ’595 memory‑module patent succeeded; all 24 claims were found obvious over a combination of prior‑art references and thus unpatentable.
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 11,386,024 patent, arguing Samsung’s record is overly voluminous and its six grounds lack particularity. The petition urges denial of institution and referral to district court.
Samsung Electronics Co., Ltd. et al. v.Netlist, Inc.
The PTAB held that Samsung Electronics' IPR against Netlist’s 8,489,837 B1 patent succeeded, finding claims 1‑3,5,6 unpatentable as obvious over prior‑art references LeClerg, Lee, and Kim. The Board adopted the petitioner’s claim constructions and rejected the patent owner’s arguments.
Samsung Electronics Co., Ltd. et al. v.Netlist, Inc.
The PTAB found all 29 claims of Netlist's ’623 memory module patent unpatentable, deeming them obvious over a combination of prior art references including Hazelzet, Buchmann, and Talbot. Samsung, as petitioner, secured a complete cancellation of the patent claims.
Samsung Electronics Co., Ltd. et al. v.Netlist, Inc.
Samsung successfully challenged Netlist’s 9,858,218 patent covering memory‑module handshaking. The PTAB found all 22 claims obvious over prior‑art combinations of Hazelzet and Buchmann. The decision also rejected the parties’ proposed claim constructions.

The PTAB denied Samsung’s request for Director Review of the institution decision in Netlist’s memory‑module patent case, leaving the institution in place.
Thermaltake Technology Co., Ltd. et al. v.Chen, Chien-Hao et al.
Thermaltake has filed an IPR petition seeking cancellation of all five claims of Lian Li’s illumination‑fan patent, arguing they are obvious over multiple prior‑art references. The petition also argues that the Board should not deny institution under discretionary statutes.
Thermaltake Technology Co., Ltd. et al. v.Chen, Chien-Hao et al.
Thermaltake seeks Director Review to overturn a PTAB decision that found its LED fan patent unpatentable. The request centers on inconsistent claim‑construction positions between the IPR and parallel district‑court litigation.
Thermaltake Technology Co., Ltd. et al. v.Chen, Chien-Hao et al.
The PTAB instituted the IPR, finding a reasonable likelihood of unpatentability for at least one claim based on obviousness. The Board specifically found evidence supporting Claim 1 over Lai and Hasegawa, while also noting inconclusive findings regarding Tsuji/Huang combinations.
Thermaltake Technology Co., Ltd. et al. v.Chen, Chien-Hao et al.
The Board found that all originally challenged claims (1-5) were unpatentable under 35 U.S.C. § 103 based on prior art combinations. Furthermore, the Patent Owner's Revised Motion to Amend was denied because proposed substitute claims lacked written description support for a key limitation.
MediaTek Inc. v.DAEDALUS PRIME LLC
MediaTek has filed an IPR petition seeking to invalidate all 21 claims of Daedalus Prime’s ‘281 patent on the ground of obviousness over multiple prior‑art references, and asks the PTAB to institute the review.
Phison Electronics Corporation v.Vervain, LLC
The PTAB denied Phison Electronics' petition for post‑grant review of Vervain's NAND‑flash storage patent, finding no sufficient evidence of unpatentability under §§ 101, 103, and 112. No claim constructions were required, and the petition was dismissed without instituting a trial.
MediaTek Inc. et al. v.MOSAID Technologies Inc.
MediaTek challenged MOSAID's patent (7051306) in an IPR, arguing that numerous claims are obvious over prior art references like Nowka and Nicol. The PTAB ultimately instituted the case after finding the petitioner satisfied Becton factors and overcame discretionary denial hurdles.
HL Klemove Corporation v.Foras Technologies Limited
HL Klemove and Foras Technologies have jointly moved to terminate the IPR over U.S. Patent 7,502,958, citing settlement and the lack of any merits decision. The Board is expected to grant the motion under 35 U.S.C. §317(a).
Phison Electronics Corporation v.Vervain, LLC
The PTAB denied Phison's post‑grant review petition against Vervain’s NAND‑flash storage patent, finding the challenger had not shown a more‑likely‑than‑not chance of unpatentability for any of the seven claims.
Microchip Technology, Inc. v.Aptiv Technologies AG et al.
Microchip Technology has filed a Director Review petition challenging the PTAB’s denial of institution in two IPRs that target Aptiv’s USB‑hub patent. The petitioner alleges the Board abused its discretion by omitting claim construction and prior‑art analysis. The request seeks reversal of the denial.
Microchip Technology, Inc. v.Aptiv Technologies AG et al.
The PTAB issued a Final Written Decision finding claims 13 and 14 unpatentable over prior art references Chang and Chang II based on obviousness (35 U.S.C. § 103). The Board adopted the Patent Owner's definition of POSITA and corrected a scrivener's error in claim 13, replacing 'hub' with 'host'.
TCL Electronics Holdings Ltd. et al. v.Intellectual Ventures I LLC
