Art, Technology and Intellectual Property. This article explores the reception of the
theory of property rights by the European directive on copyright and related rights in the
information society. It addresses the problem of the legal nature of copyright and other intellectual
property rights, having in consideration the traditional dichotomy of copyright protection for arts
and literature and industrial property protection for technical and utilitarian creations and
distinctive signs. Moreover, it is also questioned the existence of an open system of intellectual
property rights reinforced by the protection of unfair competition, covering namely trade-secrets
and companies’s good-will. Another issue addressed in this paper is the relationship between the
protection of personality rights in Civil Law systems and intellectual property rights, considering
the so-called Right of publicity. Furthermore, it is essayed to attach the protection of neighbouring
rights to the protection of the constitutional freedom of cultural creation. Finally, it is argued that
the two branches of intellectual property of the Civil Code proprietary tree do not exhaust all the
forms of intellectual property rights, since a tertium genus of IP rights is emerging, although it
implies a conceptual fragmentation of property1. O acolhimento da teoria dos property rights na directiva sobre direitos de autor na
