Since publication of the prior edition of this casebook, Congress has enacted the Leahy-Smith America Invents Act (AIA), as well as a first ever federal law for trade secret misappropriation. The AIA includes the most sweeping changes to U.S. patent law since 1952 and the casebook has been revised to focus on the new novelty and post grant proceedings contained in this Act. Additionally, the U.S. Supreme Court and the Court of Appeals for the Federal Circuit have issued dozens of significant, precedent setting opinions in areas such as patent eligibility of software and biotechnology innovations. This 7th Edition of our casebook covers each of these developments with over 400 pages of new material. Because copyright and trademark law are most often treated in separate law school courses, chapters covering these topics have been deleted.
