On December 16th, Mark Longo (@Squirrel_Dad12), owner of Internet celebrity squirrel Peanut, wrote that he has issued a cease-and-desist letter to Binance through his law firm. The lawyer's letter pointed out that Binance has used a number of intellectual property rights including the PNUT trademark and the image of squirrel wearing a cowboy hat without authorization. According to the lawyer's letter, Longo has been using PNUT-related trademarks in the United States since April 2017, mainly for educational and public welfare projects such as animal protection, wildlife and nature conservation. If the infringement is proven to be intentional infringement, the maximum compensation amount can be up to $150,000 per infringement. The lawyer asked Binance to respond and stop all infringement by December 31.
