This book discusses the problems of applicable law in international copyright infringement cases and examines the solutions proposed to them in the recent projects by the American Law Institute (ALI) and the European Max Planck Group for Conflict of Laws and Intellectual Property (CLIP). In particular, the book analyzes how the territoriality principle and the lex loci protectionis rule are applied in traditional, broadcasting and online cases in selected European and US jurisdictions. It then evaluates whether the rules on ubiquitous infringement, de minimis, initial ownership and party autonomy rule, as proposed by the ALI and CLIP Group, address the identified problems. This detailed and thorough study will appeal to academics, researchers, postgraduate and doctorate students in intellectual property and international private law, as well as EU and international policy makers in the field of intellectual property and international private law.
