Twenty One Pilots have accused Temu of marketing and selling counterfeit merch in a trademark infringement lawsuit. The band's lawyers called the China-based online retailer a "veritable swamp of infringing and otherwise illegal products", adding that it "manufactures and sells a myriad of items that are counterfeit or blatant copies of (Twenty One Pilots) artwork, trademarks and intellectual property". The suit, obtained by Rolling Stone, is filled with screenshots of what appear to be listings on Temu for an array of allegedly fake merch, including posters, shirts, mugs and socks. As the suit notes, some of the items available on Temu appear to be identical to items currently for sale on the Stressed Out artists' website. The complaint alleges that Twenty One Pilots' trademarks "have been damaged and put at risk by Temu's knowing and systematic marketing and sale of counterfeit versions", which they describe as "confusingly and/or virtually identical to" their own trademarked materials. The lawsuit opens with a pointed swipe at Temu, saying the retailer is "widely understood to be one of the most unethical companies operating in today's global marketplace." It goes on to cite a complaint recently filed by the State of Nebraska, which alleges that Temu has "flooded the United States with cheap products" and "fuels a whole host of other harms", including its alleged sale of copyright-protected materials.
