According to the documents shared by the on-chain detective @zachxbt, Nyanify, Inc. and Christopher Orlando Torres, the brand owners of the internet celebrity Grumpy Cat, have sent a lawyer's letter to the two Meme coin projects "Nyan Meme Coin" and "GrumpyCat Coin", notifying them of suspected trademark infringement and requiring them to stop the infringement.

The lawyer's letter wrote: "This infringing use creates actual confusion among consumers about the source of the goods, leading them to believe that the coin is somehow related to our client." It is reported that Grumpy Cat became popular in 2012 with 14 million fans, but died in 2019. (Planet Daily)
