Innoscience wins ruling from China’s Supreme Court after appeal by Infineon
In January, InnoScience (Suzhou) Technology Holding Co Ltd — which manufactures gallium nitride (GaN) power chips on 8” silicon wafers — and its subsidiary Innoscience (Suzhou) Semiconductor Co Ltd filed complaints (2024) Su 05 Minchu No. 1430 and (2024) Su 05 Minchu No. 1431 (regarding patent numbers 202311774650.7s and 202211387983.X) to the Intermediate People’s Court of Suzhou City in Jiangsu Province against Infineon Technologies (China) Co Ltd, its subsidiary Infineon Technologies (Wuxi) Co Ltd, and Suzhou Chipswork Electronics Technologies Co Ltd.
Two objections to the jurisdiction raised by Infineon China and Infineon Wuxi were later rejected by the court in first-instance rulings.
Infineon China and Infineon Wuxi subsequently appealed to the Supreme People’s Court, requesting transfer of the cases to the Wuxi Intermediate People’s Court for trial. However, this appeal has now been dismissed, as Chipswork was found to be one of the proper defendants in the two Suzhou cases, and is domiciled in Suzhou, so the first-instance court has jurisdiction.
InnoScience says that victory at this stage by winning disputes over jurisdiction has provided solid ground for it to proceed further with the two Suzhou cases. The firm adds that it will continue to prepare evidence and fully promote the development of the cases to defend its rights and interests.
