On September 5, 2026, the U.S. federal court ruled in the Twitter trademark case that the “Twitter” trademark is protected, but allowed others to use the generic term “tweet” and the bird-shaped logo. This decision was seen as a double-edged sword; it clarified the legal boundaries of the core logo and provided a basis for brand rebranding. As a result, Twitter officially renamed its brand to “Tweet.app”. This adjustment aimed to preserve existing user habits while avoiding legal risks. Previously, Twitter had attempted to prevent users from using its name through legal means, but this decision finally clarified the boundaries between trademarks and generic terms.
The federal court ruled that the “Twitter” trademark is protected, but allowed the use of “tweet” and the bird symbol. This decision was seen as a “double-edged sword,” prompting Twitter to officially rename its brand to Tweet.app. Previously, Twitter had attempted to prevent users from using its name through legal means; this ruling clarified the boundaries of the trademark: the core symbol “Twitter” cannot be used, while the general term “tweet” and the visual symbol (bird) can continue to be used. This decision directly affected Twitter’s brand rebranding efforts, allowing it to maintain existing user habits while avoiding legal risks.
