A Delaware judge has preliminarily split one of the most closely watched trademark fights in social media — and the Twitter revival at its center already has a new name: Tweet.app.
Key Takeaways
- On September 3, 2026, Chief Judge Colm Connolly issued a preliminary ruling in X Corp. v. Operation Bluebird — not a final judgment.
- X won on the name, for now: Bluebird is preliminarily barred from using Twitter and eight related word marks.
- Bluebird won on the other two marks: the court refused to block Tweet and the bird logo, finding Bluebird likely to prove X abandoned them.
- Within hours, the service launched on August 26 as Twitter.now became Tweet.app, restoring the bird — nicknamed the Tweenix.
- Both sides have appealed to the U.S. Court of Appeals for the Third Circuit; the main Delaware case is expected to run into late 2027.
Key Details & Core Impact
What changed
Twitter.now became Tweet.app within hours of the September 3 preliminary ruling, with the bird logo restored.
What X kept — for now
The word Twitter and eight related word marks remain off-limits to Bluebird under the preliminary order.
What Bluebird kept
Tweet and the bird logo were not blocked, after the court found Bluebird likely to prove abandonment.
What is next
Appeals were docketed October 13, 2026, and the main Delaware case is expected to run into late 2027.
Operation Bluebird is a Virginia startup co-founded by trademark attorneys Michael Peroff and Stephen Coates. Coates was Twitter’s own trademark counsel from 2014 to 2016, so this is not an outsider’s challenge to the brand — it comes from a lawyer who once defended it.
Bluebird argues that X Corp abandoned the Twitter brand when Elon Musk rebranded it to X in July 2023. In December 2025, it filed a petition with the U.S. Patent and Trademark Office to cancel X’s Twitter and Tweet trademark registrations. X countersued in Delaware federal court on December 16, 2025, in X Corp. v. Operation Bluebird, before Chief Judge Colm Connolly, saying a rebrand is not an abandonment and that Twitter never left.
At an April 2026 hearing, Judge Connolly said from the bench that X appeared to have abandoned the word tweet and the bird logo, while he was undecided on the word Twitter itself. That split in his thinking foreshadowed the written ruling that followed.
The September 3 Split Ruling
On September 3, 2026, the judge issued a written preliminary ruling that split the case down the middle. TechCrunch reported the split ruling: X won on the name, and Bluebird won on the other two marks.
| Mark | Preliminary outcome | Why it matters |
|---|---|---|
| Twitter and eight related word marks | Bluebird is preliminarily barred from using them | X still points twitter.com at X and uses the name in app-store listings. |
| Tweet | Not blocked — Bluebird was found likely to prove X abandoned it | Tweet.app can use the word that defined old Twitter. |
| Bird logo | Not blocked — Bluebird was found likely to prove X abandoned it | The restored bird, nicknamed the Tweenix, is back as the service’s mark. |
That distinction is the heart of the story, and it needs to be stated carefully. The September ruling is preliminary, not a final judgment. The court did not rule that X abandoned Twitter — on the name itself, the court sided with X for now. The abandonment finding for Tweet and the bird is a likely to succeed assessment at this stage, not a final finding that abandonment is proved.
Context & Background
Bluebird launched its social network on August 26, 2026, as Twitter.now. Ars Technica reported the launch, noting that only hundreds of users had joined at launch. The service aimed for an old-Twitter feel, with the blue bird logo, replies and retweets, and paid early access: a $20 Founding Member tier, and a $40 tier that helps fund the legal fight.
Its standout feature is Vera, a Gemini-powered automated fact-checker that scores posts for trust. That puts an AI trust layer at the center of the revival, rather than treating it as an add-on. X’s own AI assistant is Grok — see our explainer on Grok 4.5, xAI’s newest chat upgrade — so the two services are now competing on AI as well as on the old Twitter identity.
Get over your X
Coates announced the launch on LinkedIn with a message aimed squarely at X users: Get over your X. Within hours of the September 3 ruling, Bluebird acted on the other half of that message, renaming the service Tweet.app and restoring the bird.
Rival networks are also chasing former Twitter users. Meta’s Threads, for example, keeps adding features for creators — Threads is testing an in-stream podcast transcription feature — while Tweet.app is betting that the old name, word and bird still carry the strongest pull.

Industry Reaction & Consumer Next Steps
Both sides have appealed to the U.S. Court of Appeals for the Third Circuit, with the appeals docketed October 13, 2026. That means the preliminary split is now being tested from both directions: X wants the Tweet and bird wins reversed, and Bluebird wants the Twitter name back.
Reports on November 9, 2026, said the startup is readying mobile apps, with Android planned for early November. For now, the practical question for readers is not whether the old Twitter is back in full, but whether a small, paid, early-access service called Tweet.app can grow beyond the hundreds of users it had at launch while its trademark case runs on.
- Watch the Third Circuit appeals, docketed October 13, 2026.
- Watch the main Delaware case, expected to run into late 2027.
- Watch the mobile apps — reports on November 9 said Android was planned for early November.
- Watch Vera: whether a Gemini-powered trust score changes how posts are read on Tweet.app.
- Remember the guardrails: the September ruling was preliminary, and the name Twitter itself remains with X for now.
Conclusion
Tweet.app is the Twitter revival, renamed by a court order it only half lost. It kept the word Tweet and the bird, it lost the word Twitter for now, and both sides are appealing. Until the Third Circuit and then the Delaware court have their say, the bird is back — but the name is not.
