Yeti has sued Costco for allegedly selling knockoff copies of its 36-ounce Rambler cups, Law360 reports.
Costco said the product violates trademark and design patents.
“Costco’s infringing products are confusingly similar imitations of Yeti’s products and are in the same size as Yeti’s products,” Yeti claims in the suit filed in Illinois federal court.
Yeti has sued a number companies for patent infringement over the last year.
