China’s Supreme Court upholds injunction against Infineon, says Innoscience
China-based Innoscience (Suzhou) Technology Holding Co Ltd, which manufactures GaN-on-silicon power chips on 8” silicon wafers, says that the Supreme People’s Court of China has officially issued a final review decision sustaining a sales injunction against Infineon Technologies AG of Munich, Germany. So, effective immediately, Infineon is prohibited from selling its relevant gallium nitride (GaN) products within mainland China.
The Supreme Court’s ruling bolsters a prior judgment, delivered on 27 May by the Suzhou Intermediate People’s Court, that Infineon had infringed upon two of Innoscience’s core invention patents related to GaN technology. The court ordered Infineon to immediately cease all infringing activities — including the sale, offer for sale, and importation of the contested products — and awarded Innoscience RMB10m (about US$1.38m) in damages, effective immediately.
Innoscience says that, with the final review decision, the Supreme People’s Court has explicitly upheld the lower court’s injunction, bringing a definitive conclusion to the patent battle between the two firms.
