In May 2023, Efficient Power Conversion (EPC) initiated a Section 337 complaint against Innoscience Suzhou Technology Holding Co., Ltd. regarding four patents associated with gallium nitride (GaN) technology before the United States International Trade Commission (USITC). However, EPC subsequently withdrew two patents. By July of the same year, Administrative Law Judge Clark Cheney determined that while one patent had been infringed, the other had not. Following this ruling, Innoscience appealed the ITC's decision regarding the validity of the remaining patent to the U.S. Court of Appeals for the Federal Circuit. In a significant turn of events, Innoscience announced an "ultimate victory" after the United States Patent and Trademark Office (USPTO) invalidated the last patent involved in the ITC case, concluding that EPC’s claims were entirely baseless. This development represents a considerable setback for EPC, although they retain the option to appeal the ruling. Concurrently, Innoscience contends with another significant GaN-related legal battle initiated by Infineon, having filed a countersuit in a Chinese court earlier this year. In its recent communication, Innoscience asserted its commitment to moving past the disputes instigated by EPC and concentrating efforts on delivering high-quality GaN power solutions globally. The patent in question, U.S. Patent No. 8,350,294, concerning a "Compensated gate MISFET and method for fabricating the same," has had all its contested claims declared invalid by the USPTO, effectively dismantling the basis of EPC’s infringement allegations. The ruling marks a decisive conclusion to a two-year-long patent dispute. Innoscience's legal team, which included members from Finnegan, successfully secured this favorable outcome as they continue to navigate ongoing litigations involving GaN technology.
