NBA files for rights to six OKC nicknames

The NBA has filed for trademark rights to six nicknames for the league's new Oklahoma City franchise: Barons, Bison, Energy, Marshalls, Thunder and Wind.

An attorney for the league made the filing with the U.S. Patent and Trademark Office.

The filing is listed on the patent office's website.

The NBA and the team have refused to discuss possible new names for the team formerly known as the Seattle Supersonics ahead of an official announcement, which has not yet been scheduled.
