Since the Berne Convention of 1886 the copyright law governs the international protection of intellectual property of literary and artistic works. It distinguishes between works that are capable of being protected and works that cannot be protected. Consequently it has a profound effect on the value of artistic works. The internationally prevailing criterion for this differentiation is the originality of a work. My following works deal with this differentiation and the question at what point the originality is sufficient for the protection under the copyright law.
