IPNews® - Tiffany & Co. filed a lawsuit claiming that Costco Wholesalers Corp. infringed its trademarks by marketing and selling unauthorized engagement rings using the Tiffany name.

Though Costco agreed in December to cease all use of the Tiffany’s name, Tiffany is still suing Costco for its profits and treble damages.  In addition, Tiffany wants the judge to require Costco to make a public statement that it infringed Tiffany’s trademarks and to notify all customers that purchased the unauthorized rings that they did not purchase an authentic Tiffany’s engagement ring.
