Wolfspeed Files Patent Infringement Lawsuit Against Navitas Semiconductor

Key Terms

patent infringement regulatory

Patent infringement occurs when someone makes, uses, sells or imports a product or process that is covered by another party’s patent without permission — like copying a chef’s secret recipe and selling the dish without consent. For investors it matters because alleged infringement can trigger costly lawsuits, damage awards, sales bans or forced licensing, any of which can reduce revenue, increase expenses and hurt a company’s stock value.

mosfet technical

A MOSFET is a tiny electronic switch used to control the flow of electricity in chips and circuits, functioning like a faucet that turns current on or off and adjusts how much passes through. Investors watch MOSFETs because their performance, cost and availability affect product power efficiency, manufacturing yields and supply chains for industries from consumer electronics to electric vehicles, which in turn can influence companies’ margins and growth prospects.

intellectual property regulatory

Intellectual property are legal rights that protect creations of the mind—such as inventions, brand names, designs, software, or secret formulas—giving the owner control over who can use, copy or sell them. For investors, IP is like owning a blueprint or recipe: it can generate steady income through exclusive sales or licensing, boost a company’s competitive edge and valuation, and also create costs or risks if rights must be defended or challenged in court.

gallium nitride technical

Gallium nitride is a durable semiconductor material used to make electronic components that switch faster, handle higher voltages, and waste less energy than older silicon parts. Think of it as a lighter, more efficient motor in an appliance: it lets devices shrink, run cooler and save power, which can lower manufacturing costs, enable new products and boost sales or margins for companies that adopt it—key factors investors watch.

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

DURHAM, N.C.--(BUSINESS WIRE)-- 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.

"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. We respect the IP rights of others, and we expect the same respect in return," 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."
