X Wins Temporary Block on Twitter Name, But Tweet.app Can Use “Tweet” for Now

A federal court in Delaware issued a split preliminary ruling in X’s trademark fight with Operation Bluebird, a startup that tried to launch a rival social network under the name Twitter.now. The judge temporarily barred the startup from using the Twitter name, siding with X on the core “Twitter” trademark. But the court found X was likely to have abandoned the “Tweet” trademark and the Twitter bird logo, allowing Operation Bluebird to relaunch publicly as Tweet.app for now.

The dispute highlights how much value can remain in retired brand assets after a major rebrand. TechCrunch reports that Operation Bluebird’s effort is centered on picking up trademarks X allegedly relinquished when Twitter became X. For founders, brand teams, and platform operators, the takeaway is direct: unused marks can become vulnerable if a company discontinues bona fide use and appears not to intend to resume use.

Tweet.app has opened to users in early testing, and the company told TechCrunch that more than 172,000 people requested a handle before launch. The startup is charging $20 to reserve a handle and join the social network. That early interest may reflect continuing public affinity for the Twitter brand, even though the startup can no longer use the Twitter name under the preliminary order.

The court’s decision is not final, and the case will continue to determine whether X ultimately retains rights to any of the Twitter-related marks at issue. U.S. District Court Judge Colm F. Connolly granted X’s preliminary injunction request for eight Twitter-related marks, but denied it for the Tweet mark and bird logo. The next phase will be important for companies weighing whether old product language, icons, or user habits can outlive a corporate rebrand.
