X Corp. is suing Operation Bluebird for trademark infringement, claiming the startup is attempting to steal Twitter's trademarks. Operation Bluebird had petitioned the USPTO to cancel X Corp.'s ownership of "Twitter" and "Tweet" trademarks, alleging abandonment. X Corp. asserts that Twitter remains exclusively owned by them.
