First Solar has filed a lawsuit against Corning subsidiary American Panel Solutions and Chinese competitor JA Solar, alleging patent infringement. The case centers on the alleged misuse of First Solar's patents in the solar energy sector. According to the company, the legal action was initiated late Thursday.

First Solar (FSLR) sued JA Solar and Corning's (GLW) subsidiary, American Panel Solutions, for patent infringement related to TOPCon solar cell technology. The case was filed in Delaware court on October 1. First Solar acquired the patents in 2013 and has filed similar lawsuits against other solar companies this year.

First Solar filed a patent infringement lawsuit against JA Solar and Corning's subsidiary American Panel Solutions in U.S. District Court on October 1, alleging infringement of its solar PV technology patents.

First Solar (FSLR) sued JA Solar and affiliates for patent infringement over Tunnel Oxide Passivated Contact tech, filed in Delaware court. FSLR acquired the patents in 2013, valid globally until 2030. The company plans to defend its IP rights actively. In July, FSLR launched infringement probes against other solar cell makers.

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.
