The 2nd U.S. Circuit Court of Appeals on Wednesday ruled in favor of the French maker of luxury shoes worn by stars such as Sarah Jessica Parker, Scarlett Johansson and Halle Berry.
The court says Louboutin is entitled to protect its brand against red-soled shoes made by competitor Yves Saint Laurent S.A.S., which is also based in Paris.
The U.S. Patent and Trademark Office in 2008 had granted the trademark protection to Louboutin.
Louboutin has applied glossy vivid red to the outsoles of women's shoes since 1992. The shoes sell for up to $1,000 a pair.
