First Solar Moves to Withdraw TOPCon Patent Complaint at US Trade Commission
First Solar has decided to pull back from its Section 337 patent complaint concerning TOPCon solar cell technology, according to a report by TaiyangNews. The move ends a closely followed intellectual property dispute that had been pending before the US International Trade Commission (ITC), the federal body that handles Section 337 investigations into alleged unfair trade practices, including patent infringement by imported goods.
Section 337 cases are a common tool in the solar industry, where manufacturers frequently use the ITC to protect proprietary cell architectures. TOPCon — short for tunnel oxide passivated contact — has become the dominant high-efficiency cell design across the global solar manufacturing sector, making patents around the technology commercially significant.
First Solar, which takes a different technological path from most of the industry, manufactures thin-film cadmium telluride photovoltaic modules rather than the crystalline silicon cells used in TOPCon designs. The company sells its panels across the United States, France, India, Chile, and other international markets, and the case withdrawal comes as solar module makers worldwide compete on efficiency and cost.
Market reaction was negative on the session. Shares of First Solar traded at $203.10, down 4.85% from the previous close of $213.45, valuing the company at roughly $23.11 billion. The stock is listed in the technology sector within the solar industry.
Withdrawal of an ITC complaint can occur for several reasons, including settlement discussions, licensing arrangements, or a reassessment of litigation strategy. The report did not specify the terms or motivations behind First Solar’s decision to withdraw the case. Because the complaint involved TOPCon patents held by the thin-film specialist, its resolution removes one layer of legal uncertainty hanging over crystalline silicon module suppliers that sell into the US market.
Intellectual property disputes have become a recurring feature of the solar sector as manufacturers race to commercialize next-generation cell designs. Outcomes at the ITC can result in exclusion orders that block infringing imports, giving such complaints substantial commercial weight even before a ruling is issued.
What to watch
- Any formal filing or statement from First Solar or the ITC confirming the withdrawal and its terms.
- Possible disclosure of a settlement or licensing agreement in future company communications.
- First Solar’s next quarterly earnings report, which may address litigation costs and strategy.
- Further developments in other solar patent disputes involving TOPCon technology.
