The chemicals, pharmaceuticals and biotechnology industries worldwide rely upon being able to patent inventions in order to protect investment in research and development, and to reap commercial rewards. An increasingly globalised sector requires a global perspective, and this highly acclaimed book guides the reader through the legal and procedural complexities of the British, European, Japanese and US patent systems, and explains in detail the role of patentpractitioners (both in-house and in private practice) in maximising the commercial potential of their client's or company's innovative products. This eagerly awaited fifth edition provides vital updating to take account of the latest legal developments, while retaining focus on the relevant technology and industry practices that sets it apart from more general book son patent law and procedure. Patents for Chemicals, Pharmaceuticals and Biotechnology provides the reader with a complete description of the techniques and industry know-how that underlie successful patent practice and portfolio management and will be invaluable to all patent agents and practitioners working in the area of patent law. With its lucid and accessible presentation and practical approach, this book will also be welcomed by scientists, researchers and managers without a legal background.
