Using case studies, case notes, examples, and problems to illustrate points under consideration, Principles of Patent Law presents the patent law process sequentially, highlighting the legal history and discussing the intricacies of law and technology. 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 the Festo decision at both the U.S. Supreme Court and Federal Circuit levels. It also includes many more patent drawings in principal cases, provides extensive textual revisions to statutory subject matter and remedies, and offers greater comparative coverage of patent laws of U.S., Europe, and Japan, particularly related to novelty, nonobviousness, patentable subject matter, and infringement. The third edition is supplemented by a Web site, http://law.case.edu/ppl, which is organized by chapter and principal case; the Web site also includes Adobe Acrobat Portable Document Format (PDF) files of patent(s)-in-suite and prior art, as well as links to relevant patent law sites.
