This moves the dispute into trial phase, raising significant stakes in semiconductor technology licensing.
Monolithic Power Systems, Inc. v.Greenthread, LLC
Monolithic Power Systems, Inc. challenged U.S. Patent No. 10,510,842 in an IPR proceeding based on obviousness (35 U.S.C. § 103). The petitioner argued that the claimed semiconductor device features were rendered obvious by prior art references including Kawagoe and Onoda. The Board subsequently instituted the petition for trial.
Monolithic Power Systems, Inc. v.Greenthread, LLC
Monolithic Power Systems challenges U.S. Patent No. 10,734,481 in an IPR based on obviousness (103). The petitioner argues that the semiconductor device claims are anticipated or rendered obvious by prior art references including Kawagoe, Onoda, and Nishizawa. The Board has instituted the case, finding compelling evidence of unpatentability.
Monolithic Power Systems, Inc. v.Greenthread, LLC
Monolithic Power Systems challenged Greenthread's semiconductor patent in an IPR proceeding, arguing that key claims are obvious under 35 U.S.C. § 103. The Board instituted the challenge after finding compelling evidence of unpatentability based on prior art references including Kawagoe and Onoda.
Texas Instruments Incorporated v.Greenthread, LLC
Texas Instruments Incorporated filed a Petition challenging U.S. Patent No. 10,510,842, asserting that the claims are obvious under 35 U.S.C. § 103. The petitioner argues that various combinations of prior art references render the patented technology predictable and non-novel in advanced CMOS fabrication.
Texas Instruments Incorporated v.Greenthread, LLC
Texas Instruments challenged the '11121222 patent on multiple grounds of obviousness (§103), arguing that prior art references like Kawagoe, Wieczorek, and Wolf render the semiconductor device claims unpatentable. The PTAB found the merits strong and determined that institution was warranted for review.
MediaTek Inc. et al. v.MOSAID Technologies Inc.:
MediaTek Inc. initiated this Petition challenging the patentability of MOSAID Technologies Inc.'s claims related to Power Management/DVFS technology. The petitioner asserts multiple grounds of obviousness (Section 103) based on combinations of prior art references like Nowka, Borkar, Nicol, and Iyengar.
Texas Instruments Incorporated v.Greenthread, LLC
Texas Instruments Incorporated filed a petition challenging U.S. Patent No. 8,421,195 regarding CMOS fabrication/doping profiles. The petitioner asserts that the claims are anticipated or obvious based on numerous prior art references including Onoda and Payne. This challenges the patent's validity in semiconductor device technology.
Texas Instruments Incorporated v.Greenthread, LLC
Texas Instruments challenged Greenthread's '502 patent, arguing that claims related to CMOS/Flash Memory Fabrication are unpatentable under 102 and 103. The petition relies on prior art references like Onoda and Payne to demonstrate anticipation and obviousness in semiconductor device technology.
Texas Instruments Incorporated v.Greenthread, LLC
Texas Instruments (Petitioner) filed an opening petition challenging U.S. Patent No. 11,316,014 for obviousness under 35 U.S.C. § 103. The challenge targets numerous claims related to CMOS/VLSI fabrication and memory technology using various prior art combinations.
Aptiv Services US, LLC et al. v.Microchip Technology Inc.
Aptiv challenges Microchip's '665 patent on grounds of obviousness (103) related to ESD protection circuits. The challenger argues that the claimed circuit, which uses pad capacitance for energy storage, is taught or rendered obvious by prior art references like Verhaege and Miller. This initial petition sets the stage for a detailed technical battle over semiconductor device design practices.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron Technology initiated an Inter Partes Review against Yangtze Memory Technologies regarding 3D NAND Flash Memory claims.
