The purpose of this book is to explain from an economic and financial perspective, how to evaluate, calculate and present evidence on compensatory damages and other financial remedies related to the litigation involving infringement or misappropriation of intellectual property ("IP") assets. We intend the book to provide a useful resource to economists, accountants and other financial professionals who may serve as testifying experts or consultants to owners or users of intellectual property. It should also be useful to executives who manage intellectual property and intellectual property litigation attorneys. It shouldserve as a how-to primer for someone encountering intellectual property damages issues for the first time, as well as a refernce guide to those who are experienced practitioners. We hope that all will find the book clear and helpful.

           We are not attorneys and our book does not provide legal advice. We limit our explanations and discussions to the measurement and calculation of damages, avoiding any interpretation of the purely legal aspects of damages and the other financial remedies we deal with. However, in calculating damages and conducting financial and economic analysis in litigation, experts and consultants must apply their expertise within the context of case law and statutory instructions. Therefore, we necessarily discuss below our understanding of the legal rules, practices and requirements we face.

There are a number of fine books available that deal with the interpretation of patent and other IP law. We intend our work to complement those texts. Additionally, throughout our book we address and identify many texts and articles that we have found thoughful and useful.

Whenever we think it is reasonable to do so, we present alternative approaches to analyzing and computing damages. We attempt to evaluate these alternatives clearly and to present our opinions as to the relative strengths and weaknesses of the various approaches.
