The Washington Redskins ''racist'' team name could cost the National Football League side millions of dollars.
The franchise is allowed to continue to use the name, but the US Patent and Trademark Office stripped the team of any legal protection from copyright infringement.
That means the franchise will not be able to block pirated merchandise from flooding the lucrative apparel market.
The Patent Office said five Native American petitioners had established ''the name was disparaging of Native Americans when used in relation to professional football services''.
Campaigners, who call the name a racist slur, hope the loss of revenue might persuade the team's owners to change the name.
