Five years after publication of the third edition, and reflecting the dynamic nature of the pharmaceutical and medical device industries (as well as the many different areas of law that pertain to the management of these medical technologies), the Fourth Edition incorporates the latest legislative, regulatory, and judicial developments, describes recent scientific advances, and excerpts or references new scholarly contributions to this broad field (the wealth of citations should facilitate use in a seminar setting). Measured by volume, more than 20% of the previous edition has been replaced with new material. The latest edition retains the same basic thematic approach and modular structure of the original, which allows instructors to pick and choose the materials to cover based on their own tastes and areas of expertise.
