DELAWARE — U.S. District Court Judge Colm F. Connolly issued a ruling on a trademark dispute between X and Operation Bluebird. The court granted X's motion for a preliminary injunction preventing Operation Bluebird from using eight Twitter-related trademarks, including the name "Twitter."

Connolly stated that Operation Bluebird was unlikely to prove that X had entirely abandoned the Twitter name. The court ruled that Operation Bluebird is blocked from using the Twitter name until litigation is resolved because X could be irreparably harmed if Operation Bluebird benefits from using the name at X’s expense.

X argued that it still uses the Twitter name in the current listing for the X app in Apple’s App Store. The first sentence of the X app listing in Apple’s App Store states, "Welcome to X (formerly known as Twitter)." Naser Baseer testified that X "deliberately" added the clause "to ensure that people who were searching for the Twitter app within the App Store, as well as people who were searching for the Twitter app outside of the App Store, would find the Apple app link and have an understanding that this is one and the same app, same platform."

He stated that by virtue of the parenthetical, the listing is telling customers that what they knew as Twitter is now X and can be accessed by downloading the X app from the Apple App Store. Survey evidence presented to the court showed that people still consider Twitter a famous brand. He wrote that X takes advantage of the goodwill that the commercially strong initial brand maintains by associating X with Twitter in the App Store.

Why It Matters

The ruling establishes a legal boundary for the use of legacy social media branding as companies rebrand. By blocking the use of the Twitter name, the court acknowledged the continued commercial value and public recognition of the former platform identity. This decision prevents other entities from capitalizing on the established reputation of the Twitter brand while allowing X to maintain its connection to that history through specific disclosures.

The partial denial of the injunction regarding the "Tweet" mark and bird logo indicates the court found different levels of ongoing use and abandonment for those specific assets. This split decision shows the complexity of trademark protection when a company actively discontinues certain marks while retaining others. The litigation will continue toward a final resolution, with procedural steps already scheduled.

What's New

He wrote that Operation Bluebird was "likely to succeed in proving both that X Corp. discontinued the bona fide use of the Tweet mark and Bird logo and that it intends not to resume the use of the marks." The court denied X's motion for a preliminary injunction regarding the "Tweet" mark and the Twitter bird logo. Operation Bluebird originally launched under the name Twitter.now. Operation Bluebird has rebranded its website as Tweet.app.

Operation Bluebird is headed by founder Michael Peroff, a lawyer based in Illinois, and Stephen Coates, a former trademark lawyer at Twitter. Operation Bluebird charges users $20 to reserve their handle and join the social network. Operation Bluebird told TechCrunch that more than 172,000 people requested a handle on the site before launch. A Final Pretrial Conference is set for 11/15/2027 at 09:00 AM in Courtroom 4B before Judge Colm F. Connolly.
