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.
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.
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.
BMW of North America, LLC et al. v.Foras Technologies Limited
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.
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'.
LENOVO (UNITED STATES) INC. et al. v.Intellectual Ventures II
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.'
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.
Silicon Motion Inc. et al. v.K. Mizra LLC
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.
TCL Electronics Holdings Ltd. et al. v.Intellectual Ventures I LLC
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.
Samsung Electronics Co., Ltd. et al. v.Netlist, Inc.
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.
MediaTek, Inc. et al. v.Redstone Logics LLC
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.
MediaTek Inc. v.DAEDALUS PRIME LLC
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.
Microchip Technology, Inc. v.Aptiv Technologies AG et al.
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.
HL Klemove Corporation v.Foras Technologies Limited
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.
