Operation Bluebird, Inc. has renamed its Twitter.now social platform Tweet.app after the U.S. District Court for the District of Delaware issued a split ruling in X Corp.'s trademark suit. Judge Colm F. Connolly granted X Corp.'s preliminary injunction covering eight Twitter-related marks, including the TWITTER brand, but denied relief over the TWEET mark and Twitter bird logo. The court found Operation Bluebird likely to succeed in showing that X discontinued bona fide use of those two marks and does not intend to resume using them. The company has launched Tweet.app to the public in early testing, charging $20 to reserve a handle and join. More than 172,000 people requested handles before launch or advertising spending, the company said. The case will continue to determine whether X retains rights to the disputed marks, while Operation Bluebird continues developing its VERA verification technology.
