Infineon and Innoscience are locked in a global legal battle over alleged infringement involving gallium nitride (GaN) technology, with courts across multiple jurisdictions becoming battlegrounds for the dispute. In China, Innoscience appears to have gained more favourable ground, helped by its home-market position. After China’s Supreme People’s Court recently rejected a reconsideration request, Innoscience issued a press release claiming victory and saying Infineon products would be banned from sale in China.
