Covering such topics as obtaining a patent, utility, infringement, and remedies, recognized authorities provide expert commentary and advice from the viewpoint of both attorney and judge. The updated edition covers important legislative, administrative, and judicial developments, including comparative analysis with patent systems outside of the US. The Fourth Edition also continues to be accompanied by a companion website: www.innovation.hoover.org/ppl. The website is broken down by chapter and principal case. For each principal case, the patent(s)-in-suit (and prior art, when relevant) is made available. The website also provides links to relevant patent law sites, such as those providing the complete texts of applicable statutes and rules including Title 35, 37 C.F.R., and TRIPS, as well as those for important organizations including the Federal Circuit and the PTO.

This new edition captures all of the recent and rapidly emerging changes in case law and legislation, yet retains its student- and professor-friendly approach to the policies and rules of patent law. This version teaches the far-reaching legal tenets of patent law that are as venerable as the Constitution itself and yet as current as the latest developments from the laboratory bench. Like its successful predecessors, this casebook draws on insights from other areas of US law and from aspects of foreign systems as well. Because patent law plays a vital role in the international marketplace, students must understand US law in the context of international patent systems to properly represent their clients. This casebook and its robust teacher's manual make this important area of law accessible to every student.
