Washington (CNN) The Washington Redskins football team lost a key battle in court on Wednesday over their trademark registration, as a federal judge ruled to cancel the NFL team's registration, stating that the logo might denigrate Native Americans.

This decision is a setback for the team's ongoing legal and public relations battle that has taken course over the past year, but a win for Native American activists who oppose the logo, including five individuals who were faced with a lawsuit last summer, according to The Washington Post.

The cancellation will not officially take place until the team has exhausted all appeals in the Federal Courts.

The Redskins filed a lawsuit in August 2014 against five Native American activists after the group convinced a trademark agency to void the team's registration earlier that summer, the Post reported.
