Event Summary

Wolfspeed (NYSE: WOLF) filed a patent infringement lawsuit against Navitas Semiconductor (Nasdaq: NVTS) on July 7, 2026, alleging that Navitas' GaN and SiC products infringe multiple Wolfspeed patents. The suit was filed in the U.S. District Court for the Western District of North Carolina, though earlier reports mentioned the District of Delaware. Wolfspeed seeks a permanent injunction, damages, and legal fees. The dispute centers on foundational wide bandgap semiconductor IP, critical for electric vehicles and renewable energy. Wolfspeed's CEO Robert Feurle emphasized the strategic importance of protecting the patent portfolio. Navitas has not publicly responded. The lawsuit could force Navitas to redesign products, pay royalties, or enter a licensing agreement. Wolfspeed shares fell 8.79% on the day of the announcement, while Navitas shares dropped 8.14%.
