Sources: 3. Developments: 2. 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. ## Timeline ### 2026-08-10: Navitas Semiconductor sues Renesas Electronics over patent infringement Navitas Semiconductor has sued Renesas Electronics in a Texas federal court, alleging that Renesas’ SuperGaN product lines infringe on four of Navitas’ gallium nitride patent holdings. 3 sources. https://clstr.news/cluster/navitas-semiconductor-sues-renesas-electronics-over-patent-infringement ### 2026-07-30: Renesas sues US Navitas over GaN chip trade‑secret theft Renesas sues US Navitas in California, alleging stolen confidential GaN chip plans and seeking damages and an injunction. 2 sources. https://clstr.news/cluster/renesas-sues-us-navitas-over-gan-chip-tradesecret-theft --- Cite as: Renesas and Navitas semiconductor legal dispute.
