Navitas Semiconductor experienced a one-day decline of 7% in its shares Wednesday morning after being named in a patent infringement action brought by Wolfspeed in the United States District Court for the District of Delaware.
The complaint asserts that a broad assortment of Navitas products infringe on several Wolfspeed patents. The filing singles out U.S. Patent Nos. 8,169,005; 10,998,418; 10,886,396; 10,749,443; and 11,888,392 as the intellectual property at issue.
Wolfspeed's allegation covers key Navitas product families. According to the lawsuit, the accused items include Navitas’ gallium nitride-based field-effect transistors (FETs) - specifically the GaNFast, GaNSlim, and GaNSafe lines - in addition to Navitas’s GeneSiC MOSFETs and SiCPAK module offerings.
In accompanying statements, Wolfspeed framed the action as a defense of long-standing technological work. The company said it has developed what it describes as a decades-long heritage in silicon carbide materials, gallium nitride-based transistors, and silicon carbide-based MOSFETs and modules.
"Wolfspeed’s foundational technology helped create this industry, and we are deeply committed to defending the intellectual property that represents decades of innovation and R&D investment," said Robert Feurle, Wolfspeed’s chief executive officer. "Protecting our patent portfolio is a strategic priority for the company and our shareholders. This action reflects our commitment to enforcing our rights and protecting continued investment in next-generation SiC and GaN technologies."
The lawsuit and Wolfspeed's public comments highlight the company’s intent to actively police and enforce its patent rights. Navitas’s product lines named in the complaint - its GaN-based FET families and its GeneSiC MOSFETs and SiCPAK modules - are presented in the suit as allegedly covered by the identified patents.
The filing formalizes Wolfspeed’s stated priority to protect intellectual property that the company says stems from decades of research and development. The legal action and the markets' immediate reaction to the news underscore how patent disputes can quickly influence investor sentiment around companies that develop and commercialize advanced semiconductor components.
Market reaction and context
Navitas shares dropped 7% in morning trading following the announcement of the legal action. The complaint was filed in the U.S. District Court for the District of Delaware and lists specific U.S. patent numbers as the basis for infringement claims. Wolfspeed’s statement accompanying the filing emphasizes a long-term technology position in silicon carbide and gallium nitride devices and reaffirms the company’s commitment to protect those technologies through enforcement.
With the complaint naming multiple product families at Navitas, the litigation could directly touch on lines the plaintiff identifies as GaN-based FETs and specific MOSFETs and module offerings.
