First Solar Withdraws ITC Patent Complaint, Redirects Patent Fight to Federal Court Suits
First Solar has dropped its patent complaint before the U.S. International Trade Commission (ITC), opting instead to continue pursuing its claims against competing solar module makers through separate lawsuits, according to a report from Westlaw Today.
The ITC route is a common venue for U.S. manufacturers alleging unfair import practices, because the commission can order exclusion of infringing products from the U.S. market. By withdrawing the ITC case, the Tempe, Arizona–based module maker is consolidating its legal effort in the district-court litigation against rivals, where remedies typically center on damages rather than import bans.
First Solar manufactures thin-film photovoltaic (PV) modules — panels built with a semiconductor layer applied to glass, in contrast to the crystalline silicon technology used by most of its competitors — and has been an active participant in trade and patent disputes tied to solar imports. The company sells its modules across the United States, France, India, Chile, and other international markets.
Shares of First Solar fell 4.85% in today’s trading to $203.10, down from the prior close of $213.45, valuing the company at roughly $23.11 billion. The broader solar industry has been navigating shifting demand dynamics, tariff policy uncertainty, and intensifying competition from low-cost imported panels, factors that frequently shape how — and where — manufacturers choose to defend their intellectual property.
The pivot from the ITC to civil litigation keeps the patent dispute alive but changes the potential outcomes available to the company. ITC cases are often favored for their speed and the prospect of blocking imports at the border; district-court cases generally move more slowly but can yield monetary awards and injunctions against specific products.
The move comes amid continued scrutiny of supply chains and intellectual property across the U.S. solar manufacturing base, where domestic module producers have increasingly turned to legal and trade mechanisms to protect their technology portfolios.
What to watch
- Next procedural milestones and rulings in First Solar’s remaining district-court patent lawsuits against rival module makers.
- The company’s next quarterly earnings report and any updated guidance that addresses manufacturing output or litigation costs.
- Further developments in U.S. trade policy affecting solar module imports, which may influence competitive conditions in the domestic market.
