As intellectual property has grown in importance, the interaction between antitrust law and intellectual property has developed into a crucial part of the legal landscape. This new text is the first casebook expressly designed for a course on the intersection of intellectual property and antitrust law or for an advanced seminar on intellectual property misuse. It may also suitable for supplemental use in a course on intellectual property, licensing or litigation. Written by a professor who has worked in both the antitrust and intellectual property fields for over two decades, the casebook addresses both the rights of authors and inventors and the interest of society in promoting competition, expanding its base of knowledge, improving technology, and protecting consumer welfare.
