Trolls, also known as nonpracticing entities (NPEs), typically do not produce products or services but are in the business of litigation. They lie in wait for someone to create a process or product that has some relationship to the patent held by the troll, and then they pounce with threats and lawsuits. The cost to the economy is staggering. In <I>Patent Trolls: Predatory Litigation and the Smothering of Innovation</I>, William J. Watkins, Jr., calls attention to this problem and the challenges it poses to maintaining a robust rate of technological progress. After describing recent trends and efforts to “tame the trolls,” Watkins focuses on ground zero in patent litigation—the Eastern District of Texas, where a combination of factors makes this the lawsuit venue of choice for strategically minded patent trolls. He also examines a more fundamental problem: an outmoded patent system that is wholly ill suited for the modern economy. Finally, he examines proposals for reforming the U.S. patent system, which was created to spur innovation but today is having the opposite effect. If legal reformers heed the analyses and proposals presented in this book, the prospects for crafting a legal environment that promotes innovation are favorable.
