Canadian Solar ‍CSIQ-Q said on Thursday it has won a U.S. patent dispute against ‍Maxeon MAXN-Q over its ​solar-cell technology.
U.S.-listed shares of Canadian Solar rose 5.2 per cent, and those of Maxeon Solar Technologies fell 2.3 per cent.
The ⁠U.S. Patent Trial and Appeal Board invalidated all claims asserted by Singapore-based Maxeon relating to alleged infringement of patents ‌at issue ‍in the federal court litigation, ‍the company said.

In 2024, Maxeon ‌had filed a patent ⁠infringement lawsuit related to Canadian’s solar-cell technology, TOPCon.
A Maxeon spokesperson told Reuters in a statement that it is evaluating the ruling and the option ​to appeal.
“We believe we have credible legal grounds to seek reversal of the decision, and of note is the fact that the USPTO’s ⁠ruling upheld the validity of ⁠one of our TOPCon patent claims.”
Maxeon, which designs ‌and manufactures solar panels, added that it will continue to defend its intellectual property rights.
