A federal judge Friday barred Quality Inns International from using "McSleep" as the name for a budget hotel chain, saying the move was a deliberate attempt to "benefit by the good will and reputation" of the McDonald's fast food chain.

U.S. District Judge Paul Niemeyer, in a 65-page opinion, said the "Mc" prefix would cause consumers to associate the budget motel chain with the fast food operation."Therefore, the court will find trademark infringement, unfair competition and dilution," Niemeyer wrote, adding the court "will enter a permanent injunction in this case."

In September 1987, Quality Inns, a firm based in Silver Spring, Md., and the nation's third largest hotel franchiser, announced a new chain of economy hotels to be marketed under the name "McSleep Inn."
