Summary

X Corp. filed a trademark infringement lawsuit against Operation Bluebird.
Operation Bluebird seeks to claim the Twitter trademark and cancel X's.
X claims the Twitter brand is still valuable and in active use.

X Corp., formerly known as Twitter, has initiated a lawsuit against a startup named Operation Bluebird for alleged trademark infringement. The company is contesting Operation Bluebird's attempts to claim and revive the 'Twitter' brand, asserting that the brand, despite the rebrand to X in 2023, is still actively owned and utilized by X Corp.

Operation Bluebird recently announced its intention to launch a new social media platform at Twitter.new and claimed nearly 150,000 sign-ups. This move followed their petition to the U.S. Patent and Trademark Office to cancel X's trademarks for 'Twitter' and 'Tweet,' based on Elon Musk's public statements indicating the " Twitter brand" would be phased out.

In its legal filing, X highlighted ongoing daily usage of the Twitter.com domain, continued public references to the platform as Twitter, and the persistent use of Twitter marks on webpages and by third-party licensees. The company views Operation Bluebird's actions as an attempt to improperly acquire the goodwill associated with the substantial investment made in the Twitter brand.
