Court Rules X Preserves 'Twitter' Name but Forfeits 'Tweet' and Bird Logo Rights

A federal court in Delaware has issued a mixed ruling in X Corp.'s trademark conflict with startup Operation Bluebird, permitting X Corp. to temporarily safeguard the "Twitter" name while ruling that the company has likely relinquished its rights to the word "tweet" and its blue bird logo. Chief Judge Colm Connolly of the U.S. District Court for the District of Delaware issued the 31-page opinion, relying heavily on public declarations made by X owner Elon Musk as evidence that the company intended to discard those original brand elements.

The legal dispute originated in December 2025, when X Corp. initiated a lawsuit against Operation Bluebird, an entity launched by two attorneys—including a former Twitter trademark lawyer—specifically to claim rights to marks discarded by X Corp. Days before X Corp. filed its complaint, Operation Bluebird submitted applications with the U.S. Patent and Trademark Office on December 2, 2025, seeking ownership of both "TWITTER" and "TWEET."

Judge Connolly issued a preliminary injunction protecting eight "Twitter"-related marks for X Corp., citing text from the platform's official Apple App Store listing. The listing opens with "Welcome to X (formerly known as Twitter), your trusted digital town square." Naser Baseer, a legal director at X, testified that this phrasing was maintained specifically so users searching for Twitter would find X and understand it was the same service. The court concluded X Corp. continues to trade on Twitter's legacy goodwill, blocking Operation Bluebird from using the "Twitter" name until the lawsuit is resolved.

However, the court determined X Corp. failed to demonstrate active commercial use of the word "tweet" or the bird symbol as mandated under the Lanham Act. Judge Connolly emphasized that Musk's public posts on July 22, 2023—stating X would "bid adieu to the twitter brand and, gradually, all the birds," followed by comments about taking blow torches to the building's sign—carried significant evidentiary weight regarding brand abandonment. Although X Corp. obtained trademark registrations for "TWITTER FLIGHT" in August 2023 and "TWEET" on April 30, 2024, the judge noted that registration alone without ongoing commercial use cannot maintain trademark rights, as reported by The Next Web.

X Corp.'s attempts to prove ongoing commercial use of the bird logo and "tweet" mark were rejected by the court. Connolly dismissed 12 web pages submitted by X as outdated remnants of past operations rather than active branding. The court also disregarded X's unverified claim that more than 200,000 users still retain the legacy Twitter mobile app. During depositions, Baseer admitted he did not know how software push updates worked, could not specify when X last distributed an app version featuring the bird icon, and acknowledged X had never licensed the Twitter marks to third parties.

To enforce the temporary injunction preventing Operation Bluebird from using the "Twitter" name, X Corp. must post a $500,000 bond. Operation Bluebird had argued for a significantly higher bond based on projections of 10 million users in its first year, but Connolly dismissed that forecast as speculative. Instead, the judge calculated potential lost revenue using an industry average revenue per user benchmark of $0.84 applied to Bluebird's 150,000 registered users between December 2025 and May 2026, setting the bond at nearly four times that $126,000 figure. Both parties jointly requested a trial date set for November 2027.

Following the court's decision, Operation Bluebird transitioned its service to Tweet.app using the two marks it secured. In a statement to Ars Technica, Operation Bluebird President Stephen Coates said, "They kept the word. They let go of the bird, and they let go of the tweet." The startup, which charges $20 for early handle reservations and has recorded over 172,000 requests, has adopted a platform governance slogan derived from Musk's earlier statements: "freedom of speech, protected. Freedom of reach, earned."
