Mattel and MGA Entertainment Inc. have spent years in court battling over ownership of the popular Bratz doll line.
Last week, a judge awarded MGA more than $309 million for copyright infringement, trade secret misappropriation and breach of contract.
Mattel released a statement saying, "Mattel remains committed to finding a resolution that allows us to conclude this litigation on terms that are reasonable and fair to Mattel."
Mattel first filed a lawsuit in 2004 alleging that Bratz designer Carter Bryant was employed at Mattel when he created the Bratz dolls. The dolls with pouty lips, hip hop-style clothing and oversized feet were aimed at "tweens," or girls ages 9 to 11, and flew off the shelves when they debuted in 2001.
In court, MGA attorneys accused Mattel of trying to crush Bratz because the doll line was giving the venerable Barbie doll a run for her money, while Mattel accused MGA of stealing its idea for Bratz and then working to cover up any hint the concept wasn't theirs.
