Wolfspeed files patent infringement lawsuit in US against Navitas
Wolfspeed Inc of Durham, NC, USA — which makes silicon carbide (SiC) materials and power semiconductor devices — has filed a patent infringement lawsuit in the United States District Court for the District of Delaware asserting that multiple patents (including US Patent Nos. 8,169,005, 10,998,418, 10,886,396, 10,749,443, and 11,888,392) are infringed by a broad range of products of Navitas Semiconductor Corp of Torrance, CA, USA.
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 GeneSiC MOSFETs and SiCPAK modules.
Wolfspeed says that it 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 has culminated in a broad and fundamental patent portfolio that underpins the modern wide-bandgap semiconductor industry, it adds.
“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,” says CEO Robert Feurle. “We respect the IP rights of others, and we expect the same respect in return,” he adds. “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.”
