The chapter “Applicable Law” of the International Law Association’s Guidelines on Intellectual Property and Private International Law (“Kyoto Guidelines”) provides principles on the choice of law in international intellectual property matters. The Guidelines confirm the traditional principle of the lex loci protectionis for the existence, transferability, scope and infringement of intellectual property rights. The law applicable to the initial ownership of registered rights is governed by the lex loci protectionis whereas the law of the closest connection is applied to determine the ownership of copyright. For contracts, freedom of choice is acknowledged. With regard to ubiquitous or multi-state infringement and collective rights management in the field of copyright, the Guidelines suggest innovative solutions. Finally, the chapter contains a Guideline on the law applicable to the arbitrability of disputes
