Learned and pragmatic. The proposals advanced by the author to find the appropriate meaning and place for the proportionality defence in infringement actions go a long way to cure a number of dysfunctionalities which currently affect the patent system. * Marco Ricolfi, Professor of Commercial Law at the University of Turin, Italy * In a world of digitalized industrial interdependency the principle of proportionality in European patent law matters, more than ever. The role of the principle has been much debated. A reader of this book will, after absorbing its elegant analysis, come to at least this conclusion. This is the foundational treatment for which we have been waiting. * Peter Drahos, Professor, European University Institute, Italy * This insightful and thought-provoking book is essential reading for lawyers, judges, and scholars as they undertake to integrate the proportionality concept into European patent litigation. * Thomas F Cotter, Briggs and Morgan Professor of Law at the University of Minnesota Law School, USA * The book offers a modern and compelling way of looking at proportionality for injunctions in European patent law. It is a must-have for every serious patent library. * Martin Husovec, Associate Professor of Law at London School of Economics, UK * On the basis of a thorough analysis of the US four-factor test' and of EU IP enforcement law, Léon Dijkman presents a theory of bounded proportionality, governing the grant of injunctive relief in European patent law. * Ansgar Ohly, Chair for Civil Law, Intellectual Property and Competition Law at the University of Munich, Germany *
