Company takes decisive action to protect its foundational GaN and SiC intellectual property portfolio

Wolfspeed (NYSE:WOLF), a U.S.-based pioneer in wide bandgap compound semiconductor technology, today announced that it 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.
