Taco John's has held the trademark for the phrase for over 30 years. But Taco Bell argues to the U.S. Patent and Trademark Office that it has become too common a phrase to belong to a single entity.
On Tuesday, Taco Bell filed a petition to cancel Taco John’s “Taco Tuesday” trademark. Who invented Taco Tuesday? Is the phrase Taco Tuesday trademarked?
Taco Bell's attorneys challenged the US Patent and Trademark Office, saying that the "Taco Tuesday" trademark should belong to everyone, not just a certain fast food chain.
