Navitas Semiconductor has filed a patent infringement lawsuit against Renesas Electronics in the U.S. District Court for the Eastern District of Texas, escalating intellectual-property competition within the rapidly growing GaN power semiconductor market.
The lawsuit alleges that major Renesas GaN product lines, including its SuperGaN power semiconductors, infringe four Navitas U.S. patents: Nos. 9,929,079; 11,545,838; 11,770,010; and 11,862,996. Navitas said the patents form part of its broader GaN intellectual-property portfolio developed through its internal research and engineering activities.
Navitas has built a global IP portfolio of more than 300 issued and pending patents spanning its wide-bandgap semiconductor technologies. The company argues that protecting this intellectual property is increasingly important as GaN adoption expands beyond consumer power adapters into higher-power applications.
The legal action comes as Navitas shifts its growth strategy toward AI infrastructure, including AI data-center power systems and the energy and grid infrastructure supporting them. The company said momentum in these higher-power markets contributed to its second-quarter 2026 performance and that it expects revenue growth to accelerate in the third quarter as it executes its Navitas 2.0 strategy.
