China’s Supreme People’s Court confirms Innoscience’s China GaN injunctions against Infineon are interim relief

Context:

• Innoscience and Infineon have been embroiled in a multi-jurisdictional gallium nitride (GaN) patent infringement dispute since March 2024. In the Chinese prong, local company Innoscience sued Infineon in the Suzhou Intermediate People’s Court over patent infringement, while Infineon challenged the patents’ validity and tried (May 7, 2026 ip fray article), unsuccessfully, to move the dispute away from Suzhou (December 4, 2025 ip fray article).
• ip fray previously reported on the competing characterizations of Innoscience’s China win over Infineon earlier this month (June 16, 2026 ip fray article) and Infineon’s German win over Innoscience (June 19, 2026 ip fray article) a few days later. Innoscience presented the Supreme People’s Court’s (SPC) outcome as a final Chinese victory and said China’s top court had upheld a sales injunction against certain Infineon gallium nitride (GaN) products. However, in a statement to ip fray, Infineon pushed back, saying that the SPC decision concerned preliminary-injunction-style relief, not a final merits ruling. ip fray’s earlier reports considered Infineon’s procedural reading more persuasive: the timeline and China’s reconsideration mechanism for behavior-preservation orders both pointed to PI relief rather than a final SPC merits decision.
