O'Melveny & Meyers is an international Los Angeles-based full-service firm with more than 50 IP lawyers. The firm's five California offices contain the vast majority of IP lawyers, however, the firm does have a presence in New York and Washington, D.C. Copyright and trademark law are central to the firm's work in intellectual property. In recent years the firm has represented a host of the nation's largest media and entertainment companies including Sony Pictures, Walt Disney and Time Warner. In 2012, representing Time Warner and its subsidiary DC Comics, the firm scored a major victory in a copyright battle with heirs to the creators of Superman who were attempting to regain rights to the iconic comic book character. A ruling in U.S. District Court in California found that a prior agreement between Time Warner and a relative of Superman creator, Joe Shuster, prevented the family's bid to reclaim the copyrights in question.
