This completely revised and up to date Second Edition of this well received work offers in one volume a comprehensive review of United States copyright, patent, and trademark laws. It provides thorough and sophisticated treatment of this complex material in a form both less cumbersome than a treatise and considerably deeper and more sophisticated than a study outline or "nutshell." With its detailed citations, and readily accessible and complete subject coverage, this book will be a useful quick reference or deskbook for intellectual property practitioners, students, law professors, and librarians, as well as for anyone interested in understanding American intellectual property law.
