US ITC issues final ruling on Section 337

The U.S. International Trade Commission (ITC) issued a final Section 337 determination regarding certain photovoltaic trunk bus cable assemblies and components thereof (Investigation No. 337-TA-1438).

The ITC issued a final Section 337 determination regarding certain photovoltaic trunk bus cable assemblies and components thereof (Investigation No. 337-TA-1438). The ITC denied review of the Administrative Law Judge's initial determination (No. 19) issued on July 21, 2025, partially granting the applicant's motion to determine that the patents were not unenforceable because the disputed concealed information lacked but-for materiality. The ITC found that material issues of fact existed with respect to other aspects of unenforceability (including serious misconduct) and the allegations of unclean hands, but rejected those allegations.

On February 11, 2025, the U.S. International Trade Commission (ITC) voted to initiate a Section 337 investigation (Investigation No. 337-TA-1438) into certain photovoltaic trunk bus cable assemblies and components thereof.

On January 10, 2025, Shoals Technologies Group, LLC of Portland, Tennessee, filed a Section 337 investigation with the ITC, alleging that the export, import, and sale of these products into the United States violate Section 337 (infringing U.S. Patent Nos. 12,015,375 and 12,015,376) and requesting a limited exclusion order and a cease and desist order.

Voltage, LLC of Chapel Hill, N.C., and Ningbo Voltage Smart Production Co., Ningbo, China, are named as defendants.
