KITCHENER, ON, Jan. 15, 2026 /PRNewswire/ -- Canadian Solar Inc. (NASDAQ: CSIQ) (the "Company", or "Canadian Solar") today announced a decisive victory in litigation proceedings against Maxeon Solar Pte. Ltd. ("Maxeon") before the Patent Trial and Appeal Board ("PTAB") of the United States Patent and Trademark Office ("USPTO"). In Final Written Decisions, the PTAB ruled in Canadian Solar's favor, holding that all claims asserted by Maxeon against Canadian Solar relating to alleged infringement of patents at issue in the federal court litigation are invalid.

As a global leader in solar and energy storage technology, Canadian Solar has built its competitive position on proprietary R&D and sustained innovation. The Company has developed a robust global intellectual property portfolio spanning the entire value chain. This victory not only reflects the fairness and soundness of the international intellectual property protection framework, but also demonstrates Canadian Solar's solid technological foundation and its mature legal capabilities.

Colin Parkin, President of Canadian Solar, commented: "The final decision issued by the USPTO once again affirms that Canadian Solar's technology and legal teams have always respected and placed great importance on protecting both our own and our peers' intellectual property. At the same time, we firmly oppose the misuse or weaponization of patents—particularly those lacking patentability or practical value—which can distort competition and impede genuine innovation."

To date, Canadian Solar Group has filed more than 5,000 patent applications and has been granted more than 4,000 patents.
