Certain Semiconductor Devices, Products Containing Same, and Components Thereof; Inv. No. 337-TA-1500 (Violation)

This amended complaint, filed under Order No. 8, has GlobalFoundries U.S. Inc. asking the Commission to find a Section 337 violation by Tower Semiconductor Ltd. and seven affiliated entities. It asserts six patents (the '235, '983, '425, '546, '748 and '167) against Tower-made semiconductor devices and products containing them. The document does not say what changed from the original complaint of March 26, 2026. The complaint targets Tower's RF, power management, BCD, SiGe and BiCMOS foundry processes and the products using them, including a Qorvo evaluation kit, a Qorvo power tracker in a smartphone, and a Denso radar sensor in a Toyota module. GlobalFoundries seeks a permanent limited exclusion order, cease and desist orders and a bond during Presidential review. The investigation could reach downstream consumer and automotive products that incorporate Tower chips. Complainant GlobalFoundries U.S. Inc. (Malta, NY) names Tower Semiconductor Ltd. (Israel), Tower Partners Semiconductor (Japan), Tower Semiconductor Italy, and U.S. Tower entities including Tower US Holdings, Tower Semiconductor San Antonio, Tower Semiconductor Newport Beach and Newport Fab LLC as respondents. Asserted patents are U.S. Patent Nos. 8,330,235; 8,507,983; 9,093,425; 9,865,546; 10,062,748; and 10,707,167. Claims asserted include 1-9 of the '425 patent and 1-6 of the '167 patent. Accused products are devices made using Tower's RF, BCD, SiGe and BiCMOS processes, represented by the Qorvo PAC22140 Evaluation Kit, the Qorvo QM81026 RF Power Tracker and the Denso DNSRR004 Blind Spot Monitor Sensor. Domestic industry is alleged through GlobalFoundries' U.S. manufacturing, R&D and engineering activities, with domestic industry products made using its 130CBIC, CMHV7SF and CSOI8SW processes. Relief sought is a permanent limited exclusion order, cease and desist orders, and a bond during the 60-day Presidential review period. A parallel civil action is pending in W.D. Texas.
