Tiffany & Co. subsidiary filed a lawsuit against Costco Wholesale Corp on Thursday, claiming the wholesale operator has been selling engagement rings wrongly labeled "Tiffany" rings for years. Tiffany and Company alleges trademark infringement, counterfeiting, unfair competition, injury to business reputation, false advertising and deceptive business practices, according to Reuters. The company said the rings are not in fact Tiffany rings, nor are they in any way associated with Tiffany, though they have been carrying its names for years. Tiffany is seeking for Costco to forfeit profits from the ring sales, plus damages of $2 million per infringement.
