The objective of this study is identifying prospective for international legal protection of information and communication systems including artificial intelligence on the universal and regional levels, and analysis of legal instruments for protection of artificial intelligence and Big Data in the context of regulation of relations in the global information society. A complex of general scientific and philosophical methods, including the logical, comparative-legal, formal-legal, systemic-structural, and problematic-theoretical methods, as well as methods of analysis and synthesis, generalization and description were used in the research. It was found that the existing international agreements in the field of intellectual property protection take no account of the particular features of protection of complex objects. Complex objects comprise information and communication systems including artificial intelligence and Big Data. There is an objective necessity to establish a legal regime for complex objects on the universal level. The findings can be used in activities of international organizations in execution of their functions of unification and harmonization of the international information law.
