The paper presents a study of the problem of protection and protection of copyright rights in international private law. It is noted that the issue of protection and protection of copyright in the modern world is very relevant and currently not fully resolved. An analysis of international treaties, to which Ukraine is a party, has been carried out. In particular, the norms of the Berne Convention, the World Geneva Convention on Copyright of 1952, the Treaty of the World Intellectual Property Organization on Copyright (BOIB Treaty), the Agreement on Trade Aspects of Intellectual Property Rights (TRIPS Agreement) were studied. The main attention in this paper is devoted to copyright objects. It was determined that the objects of copyright include international treaties to which Ukraine is a party. It was also analyzed what differences exist in the basic conventions regarding the list of objects of copyright protection. The following criteria for the classification of copyright objects were studied: by scope of protection; by the level of accessibility for the public; by the degree of detail of their legal regulation; according to the term of legal protection. It is indicated that they are protected, unprotected, and limited copyright objects.
