patent denied

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

· IPR2024-00718

The PTAB denied MediaTek's IPR challenge against MOSAID regarding power management technology. Despite a dissenting judge arguing for reasonable likelihood based on Nowka and Borkar, the Board found Petitioner failed to demonstrate sufficient motivation or intrinsic support for its obviousness theories.

patent denied

Infineon Technologies Americas Corp. et al. v.MOSAID Technologies Inc.

· IPR2025-01171

The Director denied institution of an IPR against MOSAID's patent, ruling that Infineon failed to adequately explain conflicting claim construction positions taken in district court litigation.

patent instituted

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

· IPR2024-00599

MediaTek Inc. successfully petitioned to challenge MOSAID Technologies Inc.'s patent (7,224,563) at the PTAB, arguing that multiple claims are unpatentable over various combinations of prior art references. The Board found that discretionary denial was unwarranted, allowing the IPR proceeding to move forward.

patent instituted

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

· IPR2024-00600

MediaTek successfully petitioned to challenge 18 claims of MOSAID's patent (8854077) based on obviousness. The PTAB ruled in favor of institution, finding multiple grounds combining prior art references like Takahashi and Mizuno render the claims unpatentable.

patent null

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

· IPR2024-00720

MediaTek Inc. challenges MOSAID Technologies Inc.'s '438 Patent, asserting that the claims are obvious under 35 U.S.C. § 103. The petition relies on combining multiple prior art references (Takahashi, Mizuno, Notani) to demonstrate predictability in leakage reduction circuitry.

patent instituted

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

· IPR2024-00721

MediaTek Inc. successfully petitioned PTAB to institute an IPR against MOSAID Technologies Inc.'s patent, challenging claims related to power management in integrated circuits. The petition asserts that the challenged claims are obvious over various prior art references under 35 U.S.C. § 103.

patent instituted

Taiwan Semiconductor Manufacturing Company Ltd. v.Advanced Integrated Circuit Process LLC

· IPR2025-01302

The PTAB granted institution for IPR2025-01302, allowing Taiwan Semiconductor Manufacturing Company Ltd. to challenge the patent held by Advanced Integrated Circuit Process LLC.

patent denied

Aptiv Services US, LLC et al. v.Microchip Technology Inc.

· IPR2024-00803

The PTAB denied Aptiv Services' IPR challenges against Microchip Technology regarding ESD protection circuits (Patent No. 7564665). The Board found the Petitioner failed to overcome obviousness grounds, rejecting claims based on impermissible hindsight and insufficient explanation of prior art combinations.

patent denied

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

· IPR2024-00721

The PTAB denied MediaTek's IPR against MOSAID, finding that the Petitioner failed to demonstrate a reasonable likelihood of unpatentability over prior art references related to integrated circuit power management.

patent denied

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

· IPR2024-00720

The PTAB denied MediaTek's IPR against MOSAID's patent 8253438. The Board found that the Petitioner failed to demonstrate a reasonable likelihood of showing obviousness over prior art references like Takahashi and Mizuno, particularly regarding the 'plurality of power islands' limitation.

patent instituted

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

· IPR2024-00719

MediaTek Inc. successfully petitioned to institute an IPR against MOSAID Technologies Inc.'s patent, challenging all 64 claims based on obviousness (103). The Board found that MediaTek demonstrated a reasonable likelihood of prevailing by combining prior art references Nowka and Borkar in the field of integrated circuit power management.

patent instituted

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

· IPR2024-00600

MediaTek successfully secured institution at the PTAB against MOSAID Technologies regarding integrated circuit patents related to power management. The Board accepted Petitioner's showing of reasonable likelihood that claims are unpatentable over prior art references, including Takahashi and Mizuno.

patent instituted

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

· IPR2024-00598

MediaTek successfully petitioned to challenge MOSAID's '306 Patent, leading the PTAB to institute proceedings on 51 claims. The Board applied plain and ordinary meaning to key claim terms despite patent owner arguments, setting the stage for a full trial.

patent instituted

Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.

· IPR2025-00118

Micron Technology successfully petitioned the PTAB to challenge Yangtze Memory Technologies' patent, securing institution on multiple grounds of obviousness (103) and novelty (102). The Board found sufficient evidence that combinations of prior art references would render the claims unpatentable.
