The complaint filed by Wolfspeed asserts that Navitas’s product lines, specifically its GaN-based FETs and the GenerSiC MOSFETs and SiCPak modules, infringe on several of its established patents. These technologies are critical to high-power electronic applications, placing the core of Navitas’s hardware business under direct legal scrutiny.

Navitas has yet to issue a formal response regarding the allegations or the potential impact on its current product distribution. The lawsuit marks a sharp escalation in the ongoing rivalry between the two semiconductor developers as they compete for dominance in the high-efficiency power market.
