Business has always been driven by ingenuity and innovation. Now, more than ever, with an economy built on knowledge work and intangible value, developingâ€”and protectingâ€”intellectual property is vital for individuals and organizations alike. This book presents a brief but thorough survey of U.S. patent law, presented in the clearest possible terms for nonspecialistsâ€”including scientists, engineers, business managers, and entrepreneursâ€”as well as students and practitioners of patent and intellectual property law. Drawing from both practical and academic experience, Alan Durham explains the basis of patent law and covers such topics as the application process, claim interpretation, the requirements of novelty and non-obviousness, disclosure requirements (such as enablement and best mode), and infringementâ€”including infringement under the controversial doctrine of equivalents. Complex legal issues are explained through in-depth examples, many borrowed from actual cases, and feature such timely topics as patent protection of computer software, business methods, and biological materials. This revised and updated edition discusses recent developments in the law and draws from the most current case authority. Used as an introduction to the topic or a handy desk reference, this book will be an indispensable guide to the dynamics and mechanics of patent law.Durham illustrates complex legal issues through dozens of in-depth examples, many borrowed from actual cases.
