Luxury shoe maker Christian Louboutin lost a round in its court battle against a rival it claims unfairly copied its line of women's shoes with red soles.

The French shoe company filed the lawsuit in U.S. District Court in Manhattan in April against Yves Saint Laurent S.A.S., another French company based in Paris.

A federal judge denied Louboutin's request for a preliminary injunction. The parties have been ordered back to court next week.

The lawsuit states designer Christian Louboutin originated the concept of red soles in its shoes as a trademark nearly 20 years ago. It says he created the idea when he painted red nail polish on the black soles of a pair of women's shoes.

YSL did not comment on the suit.
