The private international law of intellectual property is currently much debated both in Europe and abroad. Art. 8 of the Rome II Regulation of 2007, which codifies a territorial approach for the infringement of intellectual property, has provoked an intensive discussion in Europe as to whether the lex loci protectionis is still appropriate in the age of worldwide networks. A condensed outcome of this debate is summarized in the CLIP Principles drafted by the European Max Planck Group on Conflict of Laws in Intellectual Property. On an international scale, the American Law Institute's "Intellectual Property: Principles Governing Jurisdiction, Choice of Law, and Judgments in Transnational Disputes" of 2007 (ALI Principles) are the focal point of the debate. A Japanese project ("Transparency proposal") was finalized in 2009. This volume provides a comparative analysis of the three proposals.
