Mueller on Patent Law Volume II: Patent Enforcement is an authoritative legal treatise available electronically on Wolters Kluwer’s CHEETAH legal research platform as a standalone subscription or as part of the IP Virtual Library. The treatise is updated annually. Mueller on Patent Law deftly illustrates and explains the intricacies of U.S. patent law with a focus on critical decisions of the U.S. Court of Appeals for the Federal Circuit and the U.S. Supreme Court. Spanning the patent system’s genesis in the U.S. Constitution through significant reforms implemented by the Leahy-Smith America Invents Act of 2011 (AIA), Volume 2 investigates the substance and procedure of enforcing U.S. patents and challenging their validity. Examining key topics such as jurisdiction, venue, and pleading in patent cases; the centrality of claim interpretation, literal infringement and infringement under the doctrine of equivalents, liability under theories of direct and indirect infringement, defenses including inequitable conduct, remedies for patent infringement, new means for challenging patents in the USPTO via AIA-implemented post-grant procedures, and international patent systems, Volume 2 provides a comprehensive look at patent enforcement in the United States and abroad.
