The National Law Journal introduces its first Intellectual Property Hot List. These 20 firms excel in providing patent, copyright and trademark legal services. They have demonstrated creative strategies for litigation, patent prosecution, licensing and other transactional work. Wilmer Cutler Pickering Hale and Dorr, for instance, stood out from the crowd by scoring two major patent wins at the U.S. Supreme Court. Cleary Gottlieb Steen & Hamilton distinguished itself by developing a unique bankruptcy auction system for roughly 6,000 Nortel patents. Each firm has shown itself to be an innovator in applying legal principles to fast-changing technology.
