US ITC’s final determination on Infineon vs Innoscience upheld after review
Infineon Technologies AG of Munich, Germany says that the Final Determination issued by the Full Commission of the US International Trade Commission (US ITC) on 7 May has been upheld after the conclusion of the 60-day Presidential Review Period. This confirms that China-based Innoscience (Suzhou) Technology Holding Co Ltd (which manufactures GaN-on-silicon power chips on 8” silicon wafers) infringes an Infineon patent concerning GaN technology, resulting in import and sales bans against Innoscience.
“This decision once again highlights the robustness of Infineon's intellectual property. It reinforces our commitment to actively protect Infineon’s patent portfolio and uphold fair competition in the industry,” says Johannes Schoiswohl, senior VP & head of the GaN Systems business line at Infineon. “With our industry-leading 300mm GaN manufacturing, we are uniquely positioned to scale innovation and deliver the performance, quality and cost advantages that our customers need to accelerate decarbonization and digitalization,” he adds.
Infineon says that this final ITC decision adds to a series of rulings in its favor concerning its GaN intellectual property. In parallel disputes in Germany, the Munich District Court (Landgericht München I) found in August 2025, then in June 2026 and at the beginning of July that Innoscience had infringed three patents and one utility model. The rulings of the German court prohibit Innoscience from importing, selling and marketing patent-infringing products in Germany. Furthermore, the court has ordered Innoscience to pay damages to Infineon.
As an integrated device manufacturer (IDM) in the GaN market, Infineon claims to have the industry’s broadest IP portfolio, comprising about 450 GaN patent families.
