Mattel Inc. on Monday asked a federal court judge in Riverside to issue an injunction against rival MGA Entertainment Inc. in the ongoing battle over the Bratz fashion doll empire.

In its motion, El Segundo-based Mattel is asking U.S. District Court Judge Stephen Larson to prevent MGA from manufacturing, distributing or selling Bratz dolls. The Barbie maker also is asking the court to stop MGA from using the Bratz name and trademark.

Larson earlier this month ordered chief executives Bob Eckert of Mattel and Isaac Larian of MGA to meet with a mediator and work out the amount of damages MGA owes Mattel and which company has the rights to the Bratz franchise. He had stayed the case until Sept. 19, preventing either side from filing motions such as the one Mattel made Monday.

A Riverside federal jury found last month that Mattel owned all but four of the original drawings upon which the Bratz dolls were based, and up to $100 million in damages and lost profits.

"Mattel owns the copyrights in the original drawings, prototypes and sculpts for the Bratz dolls," said Mattel attorney John Quinn in a statement. "And we are asking the judge to stop MGA's further infringement of Mattel's copyrights and finally put an end to its illegal conduct."

An MGA spokeswoman declined comment on the filing. Larson is scheduled to hear arguments on the injunction motion on Nov. 10.
