Wolfspeed Inc.

Wolfspeed Inc., a publicly traded company (NYSE: WOLF), is a developer and manufacturer of wide-bandgap semiconductors, primarily focusing on silicon carbide (SiC) materials and devices, as well as gallium nitride (GaN) materials and radiofrequency (RF) devices. Founded in 1987 as Cree, Inc., the company rebranded to Wolfspeed in October 2021 and is headquartered in Durham, North Carolina. As of March 29, 2026, Wolfspeed reported a trailing twelve-month revenue of approximately $712.5 million, with its third-quarter fiscal 2026 revenue at around $150 million. The company had approximately 3,434 employees as of June 2025. Wolfspeed recently underwent Chapter 11 bankruptcy protection, filing in June 2025 and emerging by September 2025.

Wolfspeed specializes in silicon carbide wafers (bare and epitaxial), discrete power devices like MOSFETs and diodes, and power modules, alongside GaN-based RF devices such as HEMTs and MMICs. These products are critical for high-efficiency applications across various sectors, including electric vehicle powertrains, fast charging infrastructure, renewable energy systems, energy storage, industrial motor drives, 5G technology, AI data centers, aerospace, and defense. The company emphasizes its position as a vertically integrated pure-play SiC manufacturer, including the production of 200mm SiC wafers.

In terms of patent litigation, Wolfspeed Inc. currently holds a posture as an active plaintiff. The company is involved in four tracked cases, all initiated by Wolfspeed Inc. as the plaintiff and zero as a defendant. All these cases were filed on July 7, 2026, in the United States District Court for the District of Delaware.

The most prominent tracked cases involve Wolfspeed Inc. as the plaintiff against Navitas Semiconductor Corp. These four recent patent infringement lawsuits against Navitas Semiconductor Corp. in the District of Delaware highlight Wolfspeed's strategy to assert its intellectual property rights in the semiconductor industry.
