Infineon wins patent dispute
ITC orders US import, sales bans on Innoscience GaN
The US International Trade Commission ruled in favour of Infineon in the patent infringement case against Innoscience. The Commission has prohibited Innoscience from importing or selling gallium nitride products in the US.
The Full Commission of the U.S. International Trade Commission (ITC) affirmed the ITC’s initial determination from December 2025 that Innoscience infringed an Infineon patent concerning gallium nitride (GaN) technology and ordered import and sales bans against Innoscience. The ITC Commission’s final decision and the bans are subject to a 60-day review period of the US President.
»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 Vice President and Head of GaN Systems Business Line at Infineon. »With our industry-leading 300-millimeter 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 continues.
The ruling is yet another positive decision which underscores the value of Infineon's contributions to GaN technology. In a parallel dispute in Germany, Infineon is asserting infringement of three patents and one utility model in the Munich District Court I (Landgericht München I). Already in August 2024, the Munich court found infringement of the first Infineon patent by Innoscience. Trials for another patent and a utility model are scheduled in June 2026.
Infineon is a GaN IDM with an IP portfolio comprising around 450 GaN patent families.
