First Solar Steps Back from Trade Commission Case on TOPCon Patents, Keeps Court Battles Alive
First Solar (NASDAQ: FSLR) said it will withdraw its Section 337 complaint filed with the U.S. International Trade Commission over intellectual property related to TOPCon solar technology, according to reporting by PV Tech. The company, however, intends to press ahead with separate lawsuits pending in U.S. District Court covering the same patent claims.
Section 337 cases allow companies to ask the ITC to block imports of products that allegedly infringe U.S. patents — a remedy that can result in exclusion orders rather than monetary damages. TOPCon, short for tunnel oxide passivated contact, is a cell architecture that has become widely adopted across the solar manufacturing industry, making related patent disputes closely watched by module makers and buyers alike.
The decision to drop the trade case while continuing district court litigation suggests the company is narrowing the venue strategy for its intellectual property claims, though it retains the ability to seek damages and injunctions through the courts. District court patent cases typically take longer to resolve but can yield financial awards in addition to restrictions on infringing products.
First Solar, which manufactures thin-film photovoltaic modules rather than TOPCon-based crystalline silicon panels, is one of the largest U.S.-headquartered solar module producers, with operations spanning the United States, India, and other international markets. Its legal posture in crystalline silicon technology disputes has been viewed as part of a broader effort by American manufacturers to assert patent rights amid intense competition from imported solar products.
Shares of First Solar closed at $203.10, down 4.85% from the previous close of $213.45, giving the company a market capitalization of roughly $23.1 billion. The decline came as the solar sector continues to digest a mix of policy, trade, and technology developments.
For project developers and utilities sourcing modules, the outcome of ongoing patent litigation could influence the long-term availability and pricing of TOPCon-based products in the U.S. market. For now, the withdrawal of the ITC complaint removes one near-term risk of an import exclusion order, while the district court cases remain the primary forum for resolving the disputed claims.
