What Recent Case Law Tells Us About the Importance of Consumer Surveys in Trademark Cases

On August 3, 2021, the U.S. District Court for the Southern District of Florida ruled against plaintiff Vital Pharmaceuticals, Inc.’s claim of trade dress infringement against defendant Monster Energy Co. due in part to plaintiff’s failure to demonstrate secondary meaning or likelihood of confusion. On June 7, 2021, the U.S. District Court for the Central District of California granted defendant lululemon’s motion for summary judgment regarding allegations of trademark infringement, basing its decision in part on plaintiff’s failure to show likelihood of confusion. Similarly, in May 2021, the U.S. District Court for the Southern District of New York ruled against plaintiff Christophe Roberts’ request for preliminary injunction against defendant Puma’s alleged trademark infringement due in part to his inability to show consumer confusion. In each of these opinions, the court noted the absence of survey evidence (or, in the Vital Pharmaceuticals case, the inadequacy of an “almost comically flawed” survey). These recent rulings underscore the increasingly important role well-designed surveys play in courts’ consideration of evidence of consumer confusion and/or secondary meaning in trademark and trade dress cases.
