The NCAA has filed a complaint in federal court seeking an emergency restraining order against online sportsbook DraftKings. The NCAA wants DraftKings to stop using registered trademarks associated with its men’s and women’s basketball tournaments. The complaint for trademark infringement was filed in the Southern District of Indiana and requests that DraftKings refrain from using terms such as “March Madness,” “Final Four,” “Elite Eight” and “Sweet Sixteen” or variations of them in sports wagering products, promotional campaigns and marketing. DraftKings says in a statement that it is not engaging in trademark infringement.
