The U.S. International Trade Commission (ITC) found the violation of one patent owned by Infineon Technologies AG concerning gallium nitride (GaN) technology by Innoscience. In addition, in this preliminary decision, the ITC confirmed that both patents asserted by Infineon in the proceedings before the ITC are legally valid. The case centers on the unauthorized use of Infineon's patented GaN technologies by Innoscience.
The Commission's final determination is expected to be issued on April 2, 2026. If this preliminary decision will be confirmed, it will lead to an import ban of Innoscience's allegedly infringing products into the United States of America. The ruling is yet another positive decision which underscores the value of Infineon's contributions to GaN technology.
In a parallel dispute in Germany, the German patent office recently confirmed the validity of a patent of Infineon and upheld it in slightly amended form. Infineon is asserting infringement of this patent in the Munich District Court. Already in August 2025, the Munich District Court I (Landgericht München I) found infringement of another Infineon patent by Innoscience.
