X and Operation Bluebird face off over the old Twitter trademark
X (formerly Twitter) just hit back at Operation Bluebird with a countersuit, after Bluebird tried to cancel X's "Twitter"-related trademarks.
The fight centers on whether X truly gave up the Twitter name and bird branding after rebranding to "X," or if those rights still stick around even after such a big change.
Why is this happening?
Operation Bluebird says X abandoned the "Twitter" brand—pointing to Elon Musk's public goodbye to the Twitter name, ditching the bluebird logo, and swapping out words like "tweet."
They argue all these moves show X left its old identity behind.
What does X say?
X disagrees and has updated its Terms of Service (effective January 15, 2026) to make it clear they still own all things "Twitter"—the trademarks for both the name and logo.
In their countersuit, they claim Bluebird is actually infringing on their rights and confusing users.
Why should you care?
This case could set a new standard for what happens when companies do major rebrands—like, can you really leave an old brand behind just by changing your name?
