Wolfspeed has filed a patent infringement lawsuit in the United States District Court for the District of Delaware against Navitas Semiconductor (“Navitas”).
The lawsuit asserts that a broad range of Navitas products infringes multiple Wolfspeed patents, including U.S. Patent Nos. 8,169,005, 10,998,418, 10,886,396, 10,749,443, and 11,888,392.
Products accused of infringement encompass major product lines of Navitas, including its GaN-based FETs — such as the GaNFast®, GaNSlim™, and GaNSafe® product families — as well as Navitas’s GeneSiC™ MOSFETs and SiCPAK® modules.
Wolfspeed has established a decades-long heritage of technological leadership in silicon carbide (SiC) materials, gallium nitride (GaN)-based transistors, and SiC-based MOSFETs and modules. That legacy of innovation has culminated in a broad and fundamental patent portfolio that underpins the modern wide bandgap semiconductor industry.
“Wolfspeed’s foundational technology helped create this industry, and we are deeply committed to defending the intellectual property that represents decades of innovation and R&D investment. We respect the IP rights of others, and we expect the same respect in return,” said Robert Feurle, Wolfspeed’s chief executive officer. “Protecting our patent portfolio is a strategic priority for the company and our shareholders. This action reflects our commitment to enforcing our rights and protecting continued investment in next-generation SiC and GaN technologies.”
