'The second edition brings the marvelous first edition up to date and adds a number of new and useful chapters. It is essential reading for student and practitioners of comparative patent law. Moreover, its comparative focus is illuminating for those who specialize in a single country's patent law by providing an enlarged perspective.'--Martin J. Adelman, George Washington University Law School, US'Professor Takenaka's Research Handbook on Patent Law and Theory is out in its second edition. It is a solid piece of work, sketching not only patent law's doctrinal bases, but also its practice. Highly recommended for patent attorneys, patent litigators, and policy makers alike!'--Christoph Ann, TUM School of Management, Germany
