First Solar is pivoting its intellectual property enforcement model to leverage new trade protections for domestic solar manufacturing. The company announced its intent to voluntarily withdraw a Section 337 complaint and terminate its pending US International Trade Commission (USITC) investigation without prejudice. This strategic recalibration follows the Trump Administration’s Section 232 national security action regarding polysilicon imports. By shifting focus from the USITC to US District Court, First Solar aims to accelerate its existing patent litigation against several major crystalline silicon solar cell manufacturers while navigating a changing regulatory landscape.
Transitioning from USITC to US District Court Litigation
First Solar is moving its legal battles against TOPCon technology infringers from the USITC to the US District Court system. The company plans to resume existing lawsuits that were previously stayed pending the Section 337 investigation results. These active cases target affiliates of Canadian Solar, Jinko Solar, T1 Energy, and Trina Solar. Beyond these specific entities, First Solar intends to resume global enforcement of its patent portfolio, a process it had paused following the initial Section 337 filing. The company’s TOPCon patent assets, acquired through the 2013 purchase of TetraSun, Inc., include validities extending to 2030 and beyond across multiple jurisdictions, including the United States, the European Union, and several Asian markets. General Counsel Jason Dymbort characterized the move as a procedural decision designed to clear the path for pending and anticipated lawsuits against what the company describes as "bad actors" infringing on its proprietary technology.
Strengthening Domestic Manufacturing and Supply Chain Independence
The company is positioning its legal and manufacturing strategies to capitalize on the recent Section 232 action, which aims to reduce Chinese influence over critical polysilicon supply chains. First Solar is emphasizing its independence from Chinese crystalline silicon, forecasting approximately 17 gigawatts (GW) of US module manufacturing capacity by 2027. To support this scale, the company expects its total investment in American manufacturing and R&D infrastructure to exceed $5 billion by the end of 2026. Currently, First Solar operates five facilities in Alabama, Louisiana, and Ohio, with a sixth plant under construction in South Carolina. This facility is expected to begin its first phase of operations in the second half of 2026. This expansion is tied to significant projected economic contributions; a study by the University of Louisiana at Lafayette suggests the company could contribute approximately $7.8 billion to US GDP and support more than 39,000 jobs by 2027.
Key Takeaways
- First Solar is withdrawing its Section 337 complaint and terminating its USITC investigation without prejudice to refile at a later date.
- The company will proceed with US District Court lawsuits against affiliates of Canadian Solar, Jinko Solar, T1 Energy, and Trina Solar.
- First Solar forecasts reaching 17 GW of US module manufacturing capacity by 2027, utilizing a supply chain with no dependence on Chinese crystalline silicon.
EnergyInsyte's Take
In our view, First Solar is executing a sophisticated legal pivot to align its IP enforcement with shifting federal trade policy. By withdrawing the USITC complaint in favor of District Court litigation, the company is likely seeking a more direct path to damages and injunctions while the Section 232 action provides a protective regulatory backdrop. This move signals that First Solar is no longer just defending its technology; it is actively weaponizing its patent portfolio to protect its massive $5 billion domestic investment. For the broader solar market, this indicates a hardening of the divide between domestic thin-film producers and international crystalline silicon manufacturers.
