Wolfspeed challenges Navitas over GaN and SiC patent boundaries - digitimes

Wolfspeed's patent lawsuit against Navitas marks a new phase in the wide-bandgap power chip competition, with the legal battle spanning both gallium nitride and silicon carbide technologies at a time ... Read original →

Wolfspeed’s lawsuit against Navitas isn’t merely about patent boundaries—it’s a strategic move to dominate wide-bandgap semiconductor leadership. Technically, while GaN and SiC follow divergent paths, their convergence in AI data center power delivery and EV fast-charging creates overlapping infringement risks, potentially delaying 800V architecture adoption. Regulatory scrutiny—possibly via the U.S. ITC—will fragment global supply chains, exposing foundries in Taiwan, China and Southeast Asia to re-licensing liabilities. Competitors like Infineon and STMicroelectronics will likely accelerate in-house GaN/SiC IP development to sidestep litigation traps. If Navitas loses, its fabless model becomes untenable in high-power segments. Over the next 18 months, expect consolidation into defensive patent pools, marginalizing smaller players and concentrating standard-setting power among IDMs—ultimately inflating BOM costs across energy infrastructure and data centers.
