The rulings follow a pattern of international legal setbacks for Innoscience, including a critical decision from the U.S. International Trade Commission in May 2025. Beyond the sales ban, the Munich court has ordered Innoscience to pay damages for the unauthorized use of Infineon’s proprietary GaN technology. These components are essential for high-performance power systems, ranging from electric vehicles to large-scale data centers and renewable energy infrastructure.

Johannes Schoiswohl, head of Infineon’s GaN business, stated that the decision reinforces the company’s commitment to protecting its portfolio, which currently encompasses approximately 450 patent families. With further litigation still pending in both Germany and the United States, the legal pressure on Innoscience continues to mount as Infineon seeks to maintain its market dominance in the semiconductor sector.
