A US district court judge agreed that Mattel’s 1999 agreement with former employee and Bratz designer, Carter Bryant, wasn’t ambiguous and that it could claim rights to work he did while at the firm.
Mattel claims that the former employee secretly took drawings of the Bratz design to MGA in 2000.
A verdict in Mattel’s favour will allow the firm to seek damages at a later trail.
Judge Stephen Larson, said: "The inventions agreement explicitly conveys to Mattel an employee's interest in any copyrights or copyright applications."
A jury trial is scheduled to begin on May 29th, 2008.
