Infineon steps up battle with Innoscience
German chip maker Infineon has expanded its GaN patent battle with China’s Innoscience (Suzhou) Technology, adding three patents to infringement allegations.
The amended complaint (filed in the US District Court for the Northern District of California) alleges that as many as 88 of Innoscience's GaN-based chips infringe Infineon patents. These include US Patent numbers 8,686,562; 9,070,755; and 8,264,003.
Earlier this year, Infineon Technologies Austria sued Innoscience alleging that 30 of its products infringed US Patent No. 9,899,481. A subsequent injunction stopped Innoscience from showing its GaN devices at last month's PCIM trade exhibition, held in Nuremberg, Germany, June 11th-13th.
Innoscience has since challenged both the validity of the original patent and the injunction, saying it only applies to the tradeshow.
Meanwhile, EPC is involved in a US court case with Innoscience about the validity of another GaN patent, ‘294, which EPC describes as its foundational patent.
