Who can legally use the word Tiffany?
In February 2013 Tiffany & Co. filed a trademark infringement lawsuit against Costco Wholesale Corp. over Costco's promotion of four and six prong solitaire engagement rings described as "Tiffany setting" rings. The case: Tiffany & Co. et al vs. Costco Wholesale Corp, 2nd U.S. Circuit Court of Appeals, No. 17-2798. TCO alleged that Costco was unlawfully using the "Tiffany" trademark to describe products that were not made or licensed by Tiffany & Co. Image Credit: The Fashi
