Navitas Semiconductor filed a patent infringement lawsuit against Renesas in the U.S. District Court for the Eastern District of Texas on August 10, 2026. The complaint alleges that Renesas violated Navitas's intellectual property rights regarding next-generation power semiconductor innovations.
This legal action intensifies a dispute that began in July 2026 when Renesas sued Navitas for trade secret theft. The initial litigation involved gallium nitride (GaN) chip technology specifically developed for AI data centers.
Navitas specializes in GaN and silicon carbide (SiC) power semiconductors. These materials are increasingly replacing traditional silicon chips in several high-growth markets.
