Wolfspeed has filed a patent infringement lawsuit against Navitas Semiconductor in the U.S. District Court for the District of Delaware, alleging that numerous GaN and SiC products infringe multiple Wolfspeed patents. The legal action underscores Wolfspeed’s strategy to protect its wide-bandgap semiconductor intellectual property as competition intensifies across the power electronics market.
According to the lawsuit, Wolfspeed alleges that several major Navitas product families infringe five U.S. patents:
- U.S. Patent No. 8,169,005
- U.S. Patent No. 10,998,418
- U.S. Patent No. 10,886,396
- U.S. Patent No. 10,749,443
- U.S. Patent No. 11,888,392
The complaint identifies a broad range of Navitas products, including:
- GaNFast® GaN power devices
- GaNSlim™ integrated GaN solutions
- GaNSafe® protected GaN devices
- GeneSiC™ silicon carbide MOSFETs
- SiCPAK® power modules
Wolfspeed stated that the lawsuit reflects its commitment to protecting the intellectual property developed through decades of research and development in silicon carbide and gallium nitride technologies.
Wolfspeed described its intellectual property as a strategic asset supporting continued investment in next-generation power semiconductor technologies.
According to CEO Robert Feurle, protecting the company’s patent portfolio is a priority for both Wolfspeed and its shareholders, emphasizing that while the company respects the intellectual property rights of others, it also expects its own innovations to receive similar protection.
