Analysis: Why Tiffany Won $15M from Costco

Attorneys Emily Miao and Daniel Organ dissect the jury’s verdict in Tiffany’s trademark lawsuit against wholesale club Costco.

Emily Miao, Ph.D., is a partner at the law firm of McDonnell Boehnen Hulbert & Berghoff LLP in Chicago. She has more than 20 years’ experience in all aspects of intellectual property practice. MBHB associate Daniel L. Organ has experience preparing and prosecuting U.S. and foreign patents in a variety of technical fields.

In a highly publicized decision last year1,  federal Judge Laura Taylor Swain of the Southern District of New York ruled in favor of the luxury retailer Tiffany & Co. (“Tiffany”), deciding that Costco Wholesale Corp. (“Costco”), the largest U.S. warehouse club chain, willfully infringed Tiffany’s trademark.

According to the court, Costco sold counterfeit diamond engagement rings bearing the Tiffany name and confused relevant consumers by using the word “Tiffany” in display case signage.  Judge Swain’s initial ruling against Costco allowed Tiffany to take Costco before a jury to seek damages, including profits from Costco’s sale of diamond rings, statutory damages, and punitive damages.

After several delays, the jury met in September for “Phase I” of the trial to decide (1) the amount of Costco’s profits and statutory damages under the Federal Lanham Act, and (2) whether Tiffany was entitled to punitive damages under New York General Business Law §349 and New York Common Law. “Phase II” was triggered when the jury found Costco liable for punitive damages. In their Phase I verdict, the Jury determined that Costco profited by $3.7 million from the infringing sales, and added an additional $1.8 million to fully compensate Tiffany, bringing the total award for profits to $5.5 million.2 The jury also awarded $2 million for statutory damages.3 The jury further held that Tiffany was entitled to punitive damages, and in the Phase II verdict awarded Tiffany another $8.25 million.4 

Analysis of Costco’s Profits
Tiffany sought an accounting of profits based on the sale of both “non-subject goods” (e.g., Costco memberships and goods other than diamond rings) and “subject goods” (e.g., diamond rings). Under Second Circuit law, in calculating “defendant’s profits,” a court should base its analysis on “infringing sales,” or sales that can be tied to the Lanham Act violation alleged.5 The court held that Tiffany presented no evidence tying the “non-subject goods” to Costco’s alleged infringement, and therefore removed the “non-subject goods” from the analysis. Regarding the “subject goods,” however, the court held that Costco did not act in good faith and therefore Tiffany was allowed to seek an accounting for profits from their sale.6 The court’s decision allowed the jury to decide, in the damages phase of the trial, how much Tiffany was entitled to for damages from Costco’s unlawful use of Tiffany’s mark.

During the damages trial, Tiffany argued that it was entitled to millions in damages from
profits realized by Costco, while Costco asserted the amount based on actual sales would be no more than $382,000.7 The jury disagreed with Costco, and awarded Tiffany $5.5 million based on Costco’s profits.

Analysis of Statutory Damages
In addition to awarding Tiffany Costco’s profits, the jury awarded Tiffany $2 million in statutory damages. The Federal Lanham Act states that when a counterfeit mark is used, up to $2 million may be awarded for a willful violation.8 In Judge Swain’s initial ruling, the court held that, as a matter of law, Costco used a counterfeit mark and that Tiffany satisfied the willfulness requirement.9 Then, to decide the exact amount of damages, the jury was instructed to consider factors such as Costco’s profits, Tiffany’s lost revenue, and the value of the mark.10 As a result, the jury determined that the maximum $2 million in statutory damages was justified.

Analysis of Punitive Damage
Tiffany sought punitive damages under both federal and state law. Under federal law, the court held that the Lanham Act prevents the collection of punitive damages.11  Under state law, however, the court noted that New York General Business Law §349 and New York Common Law allow punitive damages, albeit with an exceptionally high bar.12 Under these laws, “punitive damages are available where a defendant’s conduct has constituted gross, wanton or willful fraud or other morally culpable conduct to an extreme degree.”13 The court listed evidence in Tiffany’s favor, including emails from Costco jewelry buyers asking vendors to copy Tiffany designs and testimony that Costco employees were aware of customer confusion but did nothing to remedy it.14  

The jury ultimately agreed with Tiffany and in “Phase II” of the damages trial awarded Tiffany $8.25 million.

Conclusion
After the initial ruling, Judge Swain directed Tiffany and Costco to attempt to settle the outstanding issues. But since no settlement occurred, the damages phase proceeded and the jury handed Tiffany a sweeping victory, awarding nearly $16 million in damages.

Tiffany has been involved for many years in lawsuits regarding its intellectual property. A recent PACER search (PACER is a service for publically accessing court records electronically) returned 28 lawsuits since 1991 involving Tiffany copyrights, patents and trademarks. While the award of nearly $16 million against Costco is one of Tiffany’s largest, Tiffany previously won a default judgment of $26.5 million against numerous defendants for infringing on Tiffany trademarks and using infringing domain names.  

Costco is also no stranger to lawsuits regarding intellectual property issues, both as a plaintiff and (more often) as a defendant. A recent PACER search returned 190 lawsuits over intellectual property issues since 1991, comprising 47 trademark suits of which Costco was a defendant in 36; 119 patent suits of which Costco was a defendant in 102; and 24 copyright suits of which Costco was a defendant in 22.    

Tiffany has a history of policing its trademarks,15 in particular regarding goods such as its jewelry16,  blue gift boxes, cufflinks, and money clips17. But Tiffany has not policed its marks with respect to engagement rings--until now. The facts here were straight forward and favorable to Tiffany, so it is unsurprising that Tiffany won. Had Tiffany lost, there would have been inherent confusion around the use of the “TIFFANY” mark as applied to diamond rings and ring settings. Such a result would have been contrary to one of the purposes of trademark protection, which is to avoid consumer confusion.18  

With the conclusion of the damages trial, and assuming Judge Swain accepts the jury’s findings, Costco will likely file an appeal against Judge Swain’s ruling and the damages award. Stay tuned for further developments.
