What Happened
The U.S. International Trade Commission (US ITC) has finalized its determination that Innoscience infringes an Infineon patent on gallium nitride (GaN) technology. This ruling, confirmed after the conclusion of the Presidential Review Period on July 7, 2026, bans Innoscience from importing and selling their GaN products in the United States. The decision adds to a series of favorable rulings for Infineon in Germany, where courts have also found Innoscience in violation of multiple patents.
“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.”

industry's broadest IP portfolio
Gallium nitride is a semiconductor material that enables higher power density, faster switching speeds, and lower power losses, making it critical for applications such as renewable energy systems, AI data centers, industrial automation, and electric vehicles. Infineon is a leader in power systems, mastering silicon, silicon carbide, and gallium nitride. The company had about 57,000 employees and revenue of €14.7 billion in fiscal year 2025.
Why this matters
This patent ruling blocks a competitor's products from the U.S. market, reinforcing the value of Infineon's intellectual property. For buyers of GaN components—used in everything from EVs to data centers—the ban may limit supply options. It also signals the importance of patent protection in the fast-growing GaN industry.
