Elon Musk keeps the 'Twitter' trademark, but the iconic bird logo and the term 'Tweet' are ruled as abandoned On September 3, the Chief Judge of the Delaware Federal Court issued a preliminary ruling on the 'Twitter' trademark dispute: on one hand, the startup Operation Bluebird is prohibited from using the 'Twitter' name to launch a competing social platform, marking a win for X Corp on this claim. However, on the other hand, the court determined that X has likely abandoned the trademark rights to the term 'tweet' and the classic blue bird logo. This decision was based on Musk's public statements in 2023, such as declaring 'goodbye to the Twitter brand and all the birds,' which the court viewed as strong evidence of intent to discontinue use of the related trademarks. Following the ruling, Operation Bluebird has renamed its test platform from 'http://Twitter.now' to 'http://Tweet.app.' According to some community discussions, the court also required X Corp to pay a $500,000 bond as a condition for the injunction to take effect. Both parties are scheduled for a formal trial in November 2027.
