Patents 

Wolfspeed has invested significant resources in developing new technologies to lead the transformation from silicon semiconductor devices to semiconductor devices based on silicon carbide (SiC) and gallium nitride (GaN). Our efforts are shaping the future of semiconductor markets: the transition to electric vehicles, the evolution of renewable energy and energy storage, and the advancement of industrial applications that benefit from the advanced properties of these wide bandgap semiconductor materials. Wolfspeed continues to invest in research and development to enable new products and facilitate market growth. Wolfspeed chooses to protect many of its innovations by obtaining patents.  Accordingly, Wolfspeed has one of the most significant patent portfolios in the SiC and GaN materials and device market.  We respect the intellectual property rights of others as we expect Wolfspeed’s intellectual property rights to be respected.  We diligently and vigorously defend our intellectual property, and we have both the resources and expertise to effectively enforce our intellectual property against its unauthorized use.  As of March 2026, Wolfspeed’s global patent portfolio totals over 2,300, including issued patents and pending patent applications.  Patent marking lists directed to particular Wolfspeed product groups can be found here. 

Wolfspeed may choose to partner with other parties and promote the use of its proprietary technology through intellectual property licensing. A license to Wolfspeed's patents can enable other companies to improve existing products, enter new markets or speed time-to-market of new products.
