San Diego – (Businesswire): Haeggquist & Eck, LLP a shareholder rights litigation firm, announces an investigation of potential corporate misconduct at Costco Wholesale Corporation (“Costco” or the “Company”) (NASDAQ: COST), a warehouse store offering merchandise for sale to its members. Costco has recently been the subject of a $19.4 million judgment (the “Tiffany Judgment”) in an action filed by Tiffany & Co. (NYSE: TIF) alleging, among other things, that the Company marketed rings for sale in its membership warehouses as “Tiffany” rings in such a manner as to mislead consumers into purchasing the merchandise and causing harm to Tiffany & Co.

In addition to the litigation with Tiffany & Co., the Company has also recently been in litigation with Acushnet Company (the operating subsidiary of Acushnet Holdings Corp. (NASDAQ: GOLF)), represented to be the holder of certain Titleist golf ball patents, concerning allegations that Costco has committed patent infringement and false advertising in connection with the sale of certain golf balls in its membership warehouses.

The investigation focuses on the underlying facts surrounding the claims asserted in the above actions against Costco, including the involvement of the Company’s officers and directors in relation thereto, and the potential marketing, offer and sale of products at Costco warehouse locations in a manner that may mislead consumers and infringe the intellectual property rights of third parties.
