It's a battle between taco chain restaurants.

Taco John's, which has about 400 locations in 23 states, trademarked "Taco Tuesday" back in 1989.

Now, Taco Bell argues it should be able to get in on using the popular phrase – with no legal ramifications. It filed a petition with the U.S. Patent and Trademark Office on Tuesday asking for the trademark to be reversed.

"The Registration potentially subjects Taco Bell and anyone else who wants to share tacos with the world to the possibility of legal action or angry letters if they say 'Taco Tuesday' without express permission from Registrant – simply for pursuing happiness on a Tuesday," the company said in the filing. "This violates an American ideal: 'the pursuit of happiness.'"
