Reuters and Fashion Law report a complaint filed on September 15, 2026, in the U.S. District Court for the District of Massachusetts. The case is New Balance Athletics, Inc. v. Decathlon America LLC et al., No. 1:26-cv-14235. It is a new trademark suit. Those reports do not describe a judgment.

The complaint alleges that a KIPRUN logo is likely to be confused with New Balance's N mark, and it pleads Lanham Act claims. Do not read that as a holding. The public reports describe the filing, not a court finding that Decathlon infringed.
