As intellectual property (IP) has continued to grow in importance, the interaction between antitrust law and IP has developed into a crucial part of the legal landscape. This newly updated text is expressly designed for a course on the intersection of IP and antitrust law or for an advanced seminar on IP misuse. It may also be suitable for supplemental use in a course on advanced IP, licensing, or IP litigation. Written by a professor who has worked in both the antitrust and intellectual property fields for over three decades, the casebook addresses both the rights of authors/inventors and the interest of society in promoting competition, expanding its base of knowledge, improving technology, and protecting consumer welfare. The book includes important recent cases and the 2017 DOJ-FTC guidelines.
