Daniel Sokol, the volume collects chapters from an array of leading scholars who describe Patent Assertion Entities in the United States, Europe, Korea, Taiwan, Japan, and China, while offering empirical accounts of the entities' economic consequences and their use of litigation as a means of legal extortion against many of the most innovative companies in the world, from startups to multinationals.
