Lifang & Partners is delighted to announce that our firm client Efficient Power Conversion Corporation (“EPC”) has recently achieved another vital triumph against Innoscience (Suzhou) Technology Holding Co., Ltd. (“Innoscience”), obtaining a favorable decision from the Beijing Intellectual Property Court (Beijing IP Court) which denies Innoscience's appeal and upholds the Decision made by the China National Intellectual Property Administration (CNIPA). Case No.: (2024) Jing 73 Xing Chu No. 15061.

EPC's GaN patent No. 201080015425.X titled “COMPENSATED GATE MISFET AND METHOD FOR FABRICATING THE SAME” (Compensated Gate Patent) had been challenged by Innoscience in China, but later was validated in its entirety by the CNIPA in April, 2024 (No. 567338 Decision). Thereafter, Innoscience took an appeal to the Beijing IP Court and requested the court to overturn the CNIPA's decision. During the judicial review, the court specifically looked into the matters on whether the challenged claims comply with the Patent Law on the enablement and supporting issue, as well as whether they are obvious over the prior art, and ultimately upheld the CNIPA's decision. This judicial decision of Beijing IP Court reaffirms the validity of EPC's Compensated Gate Patent.

EPC's victories at the CNIPA and the Beijing IP Court demonstrate EPC's strength of intellectual property and its leading position in the research and development of GaN technology.

Lifang & Partners exclusively represented EPC in the related patent invalidation proceeding and administrative litigation. Throughout the proceedings, Lifang's team collaborated closely with EPC's scientists and engineers, conducting in-depth analysis of the complex technology, crafting precise yet flexible litigation strategies, and ultimately securing complete victory for EPC in both administrative and judicial proceedings through meticulous evidence preparation and rigorous legal analysis.

Lifang & Partners remains committed to providing robust protection for our clients’ intellectual property in China.
