DENVER - "Rocktober," the new shorthand for the Colorado Rockies' amazing playoff run, is showing up everywhere from newspaper headlines to handmade ballpark signs. But now the team wants a trademark to keep anyone else from selling keepsakes bearing the word.

The Rockies filed applications with the U.S. Patent and Trademark Office on Oct. 4 asking for exclusive rights to the name on stuffed animals, Christmas stockings, baby booties, T-shirts, bobble-head dolls and the like.

The filing came two days after Gov. Bill Ritter declared October would be known as "Rocktober" after the Rockies beat the San Diego Padres in 13 innings to win the wild card.

The Rocky Mountain News and The Denver Post both used the word in front-page headlines. It has also shown up in car commercials and department store ads.
