First Solar Recalibrates TOPCon IP Enforcement Strategy
First Solar is withdrawing its Section 337 complaint with the USITC but will continue patent lawsuits against Canadian Solar, Jinko Solar, T1 Energy, and Trina Solar in US District Court. The company plans to enforce its global TOPCon patent portfolio, pausing enforcement efforts after the Section 337 complaint. This follows a Trump Administration action under Section 232 aimed at polysilicon imports.
