If invention is the engine of the U.S. economy, driving the start of new companiesÂ—then intellectual property law is the fuel, helping to spur or impede the innovation that a well-designed patent system should produce. And at the center of it all is Mark Lemley. An expert on patent, trade-secret, antitrust, and constitutional law matters, he is one of the true thought leaders in the field of intellectual property, with the vantage point of multiple worlds. He is a practicing IP attorney and a founding partner of Durie Tangri LLP, one of the nation's top IP firms. He is also a legal scholar and teacher, inspiring the next generation of IP lawyers and publishing some of the most important papers on the subject.
