A federal appeals court on Monday overturned Tiffany’s $21 million judgment against Costco over the warehouse club chain’s sale of unbranded diamond engagement rings bearing the “Tiffany” name.
In a 3-0 decision, the 2nd US Circuit Court of Appeals in Manhattan said it agreed with Costco that its use of the word “Tiffany” was unlikely to confuse customers, and that Costco was entitled in good faith to describe the style of its rings even if confusion were likely.
Tiffany had sued Costco on Valentine’s Day in 2013 for trademark infringement, accusing the chain of counterfeiting.
Costco countered that “Tiffany” had become a generic term, and that it had removed “Tiffany” from store signage within one week of being contacted by that company.
The appeals court returned the case to a federal district court for a new trial.
Lawyers for Tiffany and Costco did not immediately respond to requests for comment.
Tiffany sued to protect its brand and cachet as one of the world’s best-known luxury retailers.
An estimated 3,349 customers bought Tiffany-set rings at Costco during the relevant period.
The $21 million award included $8.25 million in punitive damages, $11.1 million representing triple Tiffany’s lost profit from Costco’s alleged infringement, and interest.
