Book excerpt: A broad introduction to the changing roles of intellectual property within society Intellectual property is one of the most confusing--and widely used--dimensions of the law. By granting exclusive rights to publish, manufacture, copy, or distribute information and technology, IP laws shape our cultures, our industries, and our politics in countless ways, with consequences for everyone, including artists, inventors, entrepreneurs, and citizens at large. In this engaging, accessible study, Aram Sinnreich uncovers what's behind current debates and what the future holds for copyrights, patents, and trademarks.
