A company has filed a lawsuit in federal court against Elon Musk’s X Corp. over its renaming of Twitter. The company in question is X Social Media LLC, an ad agency from Florida that alleges X Corp. is guilty of violating Florida common law because of “unfair competition and trademark and service mark infringement,” as well as the state’s Deceptive and Unfair Trade Practices Act. X Social Media (hereafter referred to as XSM to make this article easier to write) writes in the complaint that it has used its registered trademark, “X SOCIALMEDIA,” continuously since 2016. XSM claims it has “already suffered a loss in revenue that correlates with X Corp.’s rebranding and use of the mark ‘X.’” It's unclear, however, how strong X Social Media’s case will ultimately be. Law professor Alexandra Roberts said this year that the “crowded field” of “X” trademarks could make it hard for any individual X-branded service to enforce a claim against another.
