Wolfspeed Sues Navitas Over GaN and SiC Patents - Hoodline

Two leading players in the power semiconductor industry, Wolfspeed and Navitas, have entered a patent infringement lawsuit. Wolfspeed alleges that Navitas and its affiliates have copied core wide-band... Read original →

Wolfspeed’s lawsuit against Navitas marks a pivotal inflection in wide-bandgap commercialization, not merely a legal spat. Technically, an injunction could cripple Navitas’ design flexibility in high-growth segments like EV onboard chargers and fast adapters, forcing costly redesigns of GaNFast® and GeneSiC™ platforms. Regulatory risk looms large: if the ITC initiates a Section 337 probe and finds infringement, Navitas may face U.S. import bans, jeopardizing its foothold in North American EV supply chains. Competitors like Infineon and STMicroelectronics will likely accelerate internal IP development or push cross-licensing deals to fortify their moats. Over the next 12–24 months, expect a ‘patent arms race’ that marginalizes fabless startups lacking vertical integration, while substrate-to-device integrated players—Wolfspeed, ROHM—will dictate industry standards and reshape global power semiconductor dynamics.
