There’s no ‘Breakfast at Costco,’ says Tiffany’s

Tiffany & Co. and Costco will battle it out again in court over the wholesaler’s use of the word “Tiffany” to describe its diamond solitaire rings in a six-prong setting, according to the website The Fashion Law.

The dispute between the New York-based luxury jeweler and Issaquah, Washington-based Costco has played out in district and circuit courts, with one jury awarding Tiffany more than $8 million in punitive damages for willful trademark infringement and counterfeiting.

Tiffany is accusing Costco of trying to re-litigate the case and argued in court documents that multiple Costco “Tiffany” ring purchasers believed their diamond solitaires came from the 19th-century jeweler.

Costco needs to stick with samples.
