A federal judge upheld a decision by the United States Patent and Trademark Office’s appeal board to cancel six trademarks held by the Washington Redskins, another victory for Native American groups that have been urging the team for decades to scrap its name.

The ruling was also a blow to the team, which has vociferously claimed that its name is not racist as some Native American groups contend. It is also another headache for N.F.L. Commissioner Roger Goodell, who grew up rooting for the team and has stood by owner Dan Snyder’s decision to resist calls to change the name and logo.

In a 70-page ruling, Judge Gerald Bruce Lee of the United States District Court in Northern Virginia said that the Trademark Trial and Appeal Board was correct in canceling six of the team’s trademark registrations that contain the word redskin. The board, which ruled on decisions made by the Patent and Trademark Office, agreed that the word “may disparage” Native Americans.

In August, the team went to federal court to try to overturn the decision. The team said it plans to appeal Judge Lee’s ruling.
