Viral Stanley Tumbler’s Copycat Battle Lands in Federal Court

Stanley tumblers have become a social media sensation, inspiring everything from viral trends to long lines at retailers. However, in November 2025, the company behind the iconic drinkware—Pacific Market International (PMI)—filed a high-profile lawsuit against discount retailer Five Below, accusing it of parasitic and intentional copying by selling knockoff tumblers that allegedly infringe on Stanley’s protected design patents, trademarks, and trade dress.
