patent instituted

MediaTek Inc. et al. v.MOSAID Technologies Inc.

· IPR2024-00598

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.

patent final

Thermaltake Technology Co., Ltd. et al. v.Chen, Chien-Hao et al.

· IPR2024-01230

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.

patent Final Written Decision

BMW of North America, LLC et al. v.Foras Technologies Limited

· IPR2024-01346

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.

patent Final Written Decision

BMW of North America, LLC et al. v.Foras Technologies Limited

· IPR2024-01347

BMW challenged claims of Foras Technologies' patent related to switching the boot processor role in multi-processor systems. The PTAB issued a Final Written Decision finding that the petitioner failed to prove unpatentability over prior art references.

patent Final Written Decision

Microchip Technology, Inc. v.Aptiv Technologies AG et al.

· IPR2024-00495

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'.

patent denied

LENOVO (UNITED STATES) INC. et al. v.Intellectual Ventures II

· IPR2024-01226

LENOVO failed its IPR challenge against Intellectual Ventures II's patent covering integrated circuit calibration, as the Board found Petitioner could not overcome key limitations of the claims using prior art. The denial centered on insufficient accounting for a three-dimensional 'valid operation range.'

patent instituted

Thermaltake Technology Co., Ltd. et al. v.Chen, Chien-Hao et al.

· IPR2024-01230

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.

patent instituted

Silicon Motion Inc. et al. v.K. Mizra LLC

· IPR2024-01241

Silicon Motion Inc.'s petition against K. Mizra LLC was instituted by the PTAB on grounds of obviousness (§ 103). The Board found a reasonable likelihood of success regarding multiple claims related to DRAM interface circuitry, proceeding toward a full trial.

patent denied

TCL Electronics Holdings Ltd. et al. v.Intellectual Ventures I LLC

· IPR2024-01245

TCL Electronics Holdings Ltd. failed to overcome obviousness challenges in an IPR before the PTAB, resulting in the denial of its petition. The Board found that Petitioner did not present a compelling or meritorious challenge despite analyzing multiple grounds against various prior art references.

patent instituted

Samsung Electronics Co., Ltd. et al. v.Netlist, Inc.

· IPR2025-00001

The PTAB institution decision found that Samsung Electronics demonstrated a reasonable likelihood of prevailing on its IPR challenge against Netlist, Inc.'s memory module patents. The Board determined the Office erred in its prior evaluation and applied collateral estoppel to support the petitioner's obviousness arguments over Hazelzet and Buchmann.

patent denied

MediaTek, Inc. et al. v.Redstone Logics LLC

· IPR2025-00085

The PTAB denied institution for an IPR challenge against Redstone Logics LLC's patent, finding that the petitioner failed to demonstrate a reasonable likelihood of prevailing on obviousness grounds. The dispute centered on multi-core processor design and clock ratio controllers.

patent instituted

MediaTek Inc. v.DAEDALUS PRIME LLC

· IPR2025-00100

MediaTek Inc. successfully convinced the PTAB to institute an IPR against DAEDALUS PRIME LLC's patent (9887838). The Board found that MediaTek presented a reasonable likelihood of prevailing on grounds of obviousness (103) across all 24 claimed claims.

patent null

Microchip Technology, Inc. v.Aptiv Technologies AG et al.

· IPR2024-00494

Microchip Technology challenges Aptiv Technologies' patent (9460037) in an IPR petition, arguing the claimed USB hub technology is obvious. The petitioner relies heavily on combining prior art references like Chang II and Chutorash to demonstrate predictable design evolution for dual-role ports.

patent null

HL Klemove Corporation v.Foras Technologies Limited

· IPR2024-00813

HL Klemove Corporation filed an institution petition challenging U.S. Patent No. 7,502,958 on grounds of obviousness (35 U.S.C. § 103). The petitioner asserts that the patent claims are rendered obvious by combining prior art references Bigbee and Nguyen in the field of fault-tolerant processors.
