Renesas and Navitas semiconductor legal dispute

Overview

A legal dispute has emerged between Renesas Electronics Corp and Navitas Semiconductor regarding gallium-nitride (GaN) chip technology.

In late July 2026, Renesas filed a federal lawsuit in California alleging that Navitas misappropriated confidential trade secrets. Renesas claims that Navitas used stolen PowerPoint presentations detailing next-generation GaN chip designs for data-center applications to launch a mirrored strategy and target the same customers. Renesas is seeking monetary damages and a court order to prevent further use of the alleged secrets.

In August 2026, Navitas responded by filing a patent infringement lawsuit against Renesas in the U.S. District Court for the Eastern District of Texas. Navitas alleges that Renesas’s SuperGaN power semiconductor lines infringe upon four of its patents. Navitas CEO Chris Allexandre stated the company is acting to defend its intellectual property and R&D investments in GaN and high-voltage silicon carbide (SiC) technologies.
