X keeps Twitter name, loses Tweet mark and logo

A federal court has issued a split ruling in a trademark dispute between X, the social media company formerly known as Twitter, and a startup called Operation Bluebird. The court ruled that X is likely to retain the "Twitter" trademark, but found that X had likely abandoned the terms "tweet" and the iconic blue bird logo, making them available for use by the startup. The decision came from U.S. District Judge Colm F. Connolly in the District Court of Delaware. The ruling, issued on Thursday, September 3, 2026, granted X a preliminary injunction regarding eight Twitter-related marks but denied it for the "Tweet" mark and the bird logo. This partial preliminary injunction means Operation Bluebird cannot use the name "Twitter" for its services, as the court determined X's continued use of the name, including in its App Store listing, would likely lead to consumer confusion and infringement. In response to the ruling, Operation Bluebird has rebranded its social media platform from Twitter.now to Tweet.app. The company stated that the court declined to block its use of the "Tweet" mark and the bird logo, finding that X Corp. had likely abandoned both.
