U.S. International Trade Commission Rules in Favor of Infineon in Patent Case Against Innoscience
December 3, 2025 — Munich, Germany
The U.S. International Trade Commission (ITC) has issued a ruling confirming that Innoscience infringed one of Infineon Technologies AG’s patented gallium nitride (GaN) technologies. This follows an earlier initial determination in which the ITC upheld the validity of two Infineon patents. According to the latest decision, Innoscience was found to have used Infineon's protected GaN technology without authorization. A final ruling is expected on April 2, 2026, which may result in a ban on the import of the infringing products into the United States.
A senior spokesperson from Infineon’s GaN business stated:
“This decision reinforces our strong intellectual property foundation and reflects our commitment to protecting innovation and ensuring fair market competition. We remain dedicated to advancing semiconductor technologies that support global transitions toward decarbonization and digitalization.”

With this ruling, Infineon further solidifies its leadership in the GaN power semiconductor field. As one of the world’s leading integrated device manufacturers (IDMs), the company holds a broad IP portfolio containing approximately 450 GaN-related patent families. GaN technology continues to play a critical role in high-performance and high-efficiency power systems, ranging from renewable energy and AI data centers to industrial automation and electric vehicles (EVs).
Compared with traditional silicon-based solutions, GaN enables higher power density, faster switching speeds, improved energy efficiency, and more compact system designs—making it an increasingly important material for next-generation power electronics.
