Investigation Could Block TOPCon Imports
First Solar filed a complaint alleging that certain TOPCon solar products infringe U.S. Patent No. 9,130,074. The company asked the Commission to investigate and, after the investigation, issue a general exclusion order or a limited exclusion order and cease and desist orders that could stop those TOPCon cells, modules, and panels from being imported into or sold in the United States.
Respondents Must File Responses Within 20 Days
Named respondents must submit responses to the complaint and notice of investigation in accordance with Commission rules, and any such responses will be considered if received not later than 20 days after the date of service by the Commission. The notice warns that failure to file a timely response may be deemed a waiver and could lead to initial and final determinations and issuance of an exclusion order or a cease and desist order against the respondent.
Investigation Specifically Covers TOPCon Products
The Commission defined the scope of the investigation as 'Tunnel Oxide Passivated Contact ("TOPCon") solar cells, as well as solar modules and solar panels that include TOPCon solar cells.' This tells manufacturers, importers, and sellers which types of products are explicitly covered by the inquiry.
