- Certain Graphics Systems, Components Thereof, and Consumer Products Containing the Same (337-TA-1044) – Represented Advanced Micro Devices (AMD) as complainant in the ITC asserting patents covering graphics processing technology employed by smart devices such as televisions and handsets. Respondents include LG Electronics, VIZIO, MediaTek, and Sigma Designs, Inc. (SDI). Achieved settlement with LG prior to the conclusion of expert discovery. Following the evidentiary hearing, the presiding ALJ issued an initial determination finding a violation of Section 337 and recommending the imposition of an exclusion order against the remaining Respondents’ accused products. The ITC affirmed the ALJ’s finding of a violation on August 22, 2018. As a result, the Commission issued orders banning the importation of products made by VIZIO, MediaTek, and SDI and cease and desist orders against VIZIO and SDI.
- Certain Computing or Graphics Systems, Components Thereof, and Vehicles Containing Same (337-TA-984) – Represented owner of portfolio of graphics processing and microprocessor patents, Advanced Silicon Technologies, LLC, as Complainant in an ITC investigation adverse to a number of automotive manufacturers, and infotainment system and chip suppliers. Respondents include Honda, Toyota, BMW, Audi, Volkswagen, NVIDIA, Texas Instruments, Renesas, Harman International, and Fujitsu-Ten. The investigation instituted in January of 2016 and resolved favorably prior to the conclusion of expert discovery in August of 2016.
- Certain Video Processing Devices, Components Thereof, and Digital Smart Televisions Containing the Same (337-TA-1222) – Represented DivX, a video codec company headquartered in San Diego, in enforcing patents before the ITC in the District of Delaware. The asserted patents involve innovations relating to digital rights management and streaming media. LG and Samsung settled after the Markman order was issued, leaving TCL as the sole remaining respondent. Shortly after the seven day evidentiary hearing held in July 2021, one of the two principal suppliers of the accused streaming technology to TCL, namely Roku, stepped in and took a license to DivX’s portfolio, thus partially resolving DivX’s claims against TCL. Prior to the court issuing a decision on the merits, DivX and TCL entered into a bilateral settlement agreement resolving DivX’s remaining claims against TCl and bringing an end to all pending litigation.
- Certain Semiconductor Devices, Products Containing the Same, and Components Thereof (II) (337-TA-1177) - Represented GlobalFoundries at the International Trade Commission and in multiple Western District of Texas actions, involving the direct and indirect infringement of four patents related to semiconductor devices, integrated circuits, and products containing the same. Additional defendants in these actions included Apple, Broadcom, Cisco, nVidia, Arista, Asus, and Lenovo. Within 2.5 months of filing at the ITC, the cases settled on favorable terms.
- Certain Semiconductor Devices, Integrated Circuits, and Consumer Products Containing the Same (337-TA-1149) – Mintz represented Innovative Foundry Technologies as part of a global enforcement strategy to protect 5 asserted patents relating to semiconductor fabrication and packaging. Respondents for the ITC matter included Taiwan Semiconductor Manufacturing Company, Qualcomm Incorporated, MediaTek, and Vizio. Cases were simultaneously filed in U.S. District Court and internationally in Germany and China. The investigation was instituted in March of 2019 and resolved favorably prior to the conclusion of discovery in August of 2019.
