Wolfspeed has filed a patent-infringement lawsuit against Navitas Semiconductor in the U.S. District Court for the District of Delaware, alleging that several of Navitas’s gallium nitride and silicon carbide power-semiconductor products infringe five Wolfspeed patents.
Per Wolfspeed’s July 7 announcement, the disputed portfolio covers U.S. patents 8,169,005; 10,998,418; 10,886,396; 10,749,443; and 11,888,392. The company names Navitas’s GaNFast, GaNSlim and GaNSafe gallium-nitride FET families, plus GeneSiC MOSFETs and SiCPAK silicon-carbide modules, as accused products.
The case, Wolfspeed v. Navitas Semiconductor Corporation et al., was filed July 7 with a jury demand. Court records listed Navitas Semiconductor Corporation, Navitas Semiconductor Ireland, Navitas Semiconductor USA and GeneSiC Semiconductor as defendants; summonses were served on July 8, with responses then due July 29.
Navitas responded the following day in a press release attached to an SEC Form 8-K. The company said it disputes Wolfspeed’s allegations, called them “baseless accusations of infringement,” and said it will defend its products vigorously and expects to prevail.
That matters because the lawsuit is not a finding of infringement. Wolfspeed must first establish that the asserted patents are valid, enforceable and cover the named products; Navitas can contest each of those points. The case could end in a settlement, licensing agreement, redesigns, invalidated claims, or a trial verdict—none of which is imminent.
Navitas sells such parts into markets including power adapters, data-center power equipment, solar and energy infrastructure, industrial systems, and electric vehicles. Wolfspeed has long been a major SiC supplier and has positioned its patent portfolio as foundational to the broader GaN and SiC power-device market.
For Windows users, this is not a PC compatibility issue and does not require any patching or configuration changes. The products at issue are power components rather than Windows software, processors, graphics cards, or motherboard chipsets. Any practical effect would be indirect: a protracted legal fight could eventually affect sourcing, product roadmaps, pricing, or component availability for hardware vendors using the disputed Navitas lines.
The next concrete milestone is Navitas’s court response, unless the parties seek an early extension or reach an agreement before then.

Navitas disputes the allegations

The company said it disputes Wolfspeed’s allegations, called them “baseless accusations of infringement,” and said it will defend its products vigorously and expects to prevail.That matters because the lawsuit is not a finding of infringement.

Why the chips matter
The dispute concerns “wide-bandgap” power technologies: gallium nitride (GaN) and silicon carbide (SiC). These materials can switch power more efficiently and at higher frequencies than conventional silicon in appropriate designs, enabling smaller or cooler power-conversion hardware.Navitas sells such parts into markets including power adapters, data-center power equipment, solar and energy infrastructure, industrial systems, and electric vehicles.

What IT buyers should do
There is no immediate action for most organizations. Enterprises specifying high-efficiency power gear, chargers, industrial PCs, edge systems, or data-center infrastructure that explicitly relies on Navitas GaN or SiC components should track supplier notices, but should not assume current products are unavailable or noncompliant.The next concrete milestone is Navitas’s court response, unless the parties seek an early extension or reach an agreement before then.
