In light of a federal court ruling in the well-publicized trademark fight between Tiffany & Co. and Costco Wholesale Corp. over Cosco’s use of the Tiffany name in marketing materials, Tiffany is now at risk of losing its trademark on the term “Tiffany setting.”

Southern District Judge Laura Taylor Swain (See Profile) in Manhattan on Jan. 17 held that a jury could reasonably find that the term is generic and the trademark invalid. The ruling denied Tiffany’s request for summary judgment on the trademark’s validity.
