Operation Bluebird was founded by Stephen Coates, Twitter's former intellectual property counsel, to reclaim the 'Twitter' and 'Tweet' trademarks from X, which had abandoned them, and restore the Twitter of its past. Operation Bluebird filed a complaint with the U.S. Patent and Trademark Office seeking the cancellation of the 'Twitter' trademark, alleging that X had abandoned the trademark.

On December 16, 2025, local time, Elon Musk's X filed a lawsuit against Operation Bluebird. In the complaint filed in federal court in Delaware, X argued that 'the Twitter brand is still alive and well and is not in a position to be seized by anyone' and 'continues to exist in various forms.'

In fact, more than two years after the name change, millions of users still access the platform through 'twitter.com' at the time of writing, and there are several users and companies who refer to X as 'Twitter.' The lawsuit also claims that Operation Bluebird's efforts are an 'attempt to steal' and constitute trademark infringement.

'Twitter is one of the most recognized brands in the world, and its rights belong to X,' X wrote in its complaint. 'In short, the rebranding does not constitute a waiver of any trademark rights.' X also argued that Operation Bluebird's use of the 'Twitter' trademark would cause consumer confusion.

In response to the lawsuit, Michael Perov, one of the founders of Operation Bluebird, issued a statement saying, 'Our trademark cancellation claim is based on established trademark law and we believe we will be successful. We are prepared to fight this case vigorously if necessary to achieve our goals.'

In response to the lawsuit, X's public relations officer and attorney have not commented on the comments made by Operation Bluebird at the time of writing.
