In July, O’Melveny sued MGA in Los Angeles superior court for $10.2 million in unpaid legal fees related to the company’s long-running litigation against rival Mattel, Inc., over MGA’s Bratz doll line. MGA responded to O’Melveny’s fee demand the following month with a malpractice cross-complaint.

Now, in a spate of filings, the two sides are arguing over when the trial should take place. On October 29, O’Melveny filed its opposition to MGA’s motion to stay the proceedings. The firm’s move elicited a response on Thursday in which MGA describes O’Melveny’s arguments as “not persuasive.”
