In July 2023, Elon Musk’s X Corp. rebranded the social media platform Twitter to “X,” replacing the iconic blue bird logo and transitioning the domain from twitter.com to x.com. This transformation included phasing out terms like “tweet” and “retweet” from the platform’s vernacular. Musk signaled this shift with a post stating, “And soon we shall bid adieu to the Twitter brand and, gradually, all the birds.”
In December 2025, Operation Bluebird, a Virginia-based startup, filed a petition with the U.S. Patent and Trademark Office (USPTO) to cancel X Corp.’s trademarks for “Twitter” and “tweet.” The startup argued that X Corp. had abandoned these trademarks by eliminating the Twitter brand from its products, services, and marketing, with no intention to resume their use. Operation Bluebird, led by former Twitter trademark lawyer Stephen Coates, aims to launch a rival social media platform under the name “twitter.new.” ([arstechnica.com](https://arstechnica.com/information-technology/2025/12/can-twitter-fly-again-startup-wants-to-pry-iconic-trademark-from-musks-x/?utm_source=openai))
In response, X Corp. updated its Terms of Service to assert ownership of both the X and Twitter trademarks, stating that users may not use these names or associated trademarks without express written consent. Additionally, X Corp. filed a countersuit against Operation Bluebird, emphasizing that the Twitter brand remains one of the world’s most recognized and continues to persist in various ways. The company highlighted that millions of users still access the platform through twitter.com and that the terms “Twitter” and “tweet” are still widely used by the public and businesses.

Legal experts suggest that Operation Bluebird faces significant challenges in proving that X Corp. has abandoned the Twitter trademarks. Trademark attorney Josh Gerben noted that popular recognition still associates the “Twitter” brand with X Corp., and there are no similar precedents of a company dissociating itself from such a significant brand.

The outcome of this legal dispute will have implications for trademark law, particularly concerning brand abandonment and rebranding strategies. As the case progresses, it will provide insights into how companies can protect their intellectual property rights during significant brand transformations.
