Innoscience files lawsuits against Infineon in China
InnoScience (Suzhou) Technology Holding Co Ltd and its subsidiary InnoScience (Suzhou) Semiconductor Co Ltd have filed complaints regarding patent number 202311774650.7s and 202211387983.X with the Intermediate People’s Court of Suzhou City, Jiangsu Province, against Infineon Technologies (China) Co Ltd, its subsidiary Infineon Technologies (Wuxi) Co Ltd, and Suzhou Chipswork Electronics Technologies Co Ltd.
The patents relate to a gallium nitride (GaN) power device and preparation method, and a nitride-based semiconductor device and method for manufacturing it, respectively. According to the complaints, Infineon Technologies (Wuxi) Co Ltd is the filing entity of Infineon’s Chinese website, which displays, advertises and sells various models of GaN devices to potential customers in China. Infineon Technologies (China) Co Ltd is the importer and general distributor of the infringing products involved. According to Infineon’s Chinese website, Suzhou Chipswork Electronics Technologies Co Ltd is the value-added distributor of Infineon Technologies (China) Co Ltd and Infineon Technologies (Wuxi) Co Ltd in China.
After technical comparison, InnoScience believes that the infringing products fall within the scope of protection of the patents involved. The three defendants, without InnoScience’s permission, implemented the offer for sale, sale and import of the infringing products, constituting infringement of the patents, and should bear the corresponding legal responsibilities in accordance with the laws, including ceasing infringement and assuming liability for compensation, says InnoScience.
