This wide-ranging Research Handbook is the first to offer a stimulating and systematic review of the framework for criminal enforcement of intellectual property rights. If counterfeiting constitutes an ever-growing international phenomenon with major economic and social repercussions, potentially affecting consumer safety and public health, the question of which are the appropriate instruments to enforce IP rights is a complex and sensitive one. Although criminal penalties can constitute strong and effective means of enforcement, serious doubts exist as to whether criminal sanctions are appropriate in every infringement situation. Drawing on legal, economic, historical and judicial perspectives, this book provides a differentiated sector-by-sector approach to the question of enforcement, and draws useful conclusions for future legislative initiatives at European, international and national levels.
