Relevance. The article considers the problems caused by the limited possibilities of legal registration of relations between investors and persons creating the results of intellectual activity or organizing the creation of RIA. It is noted that the obligatory rights based on contracts concluded by investors do not allow to fully take into account their interests and provide guarantees of their observance when disposing of exclusive rights to the intellectual property created with the attraction of investment funds. The conclusions are substantiated that taking into account the growing needs in attracting investment funds for the implementation of projects related to the creation and use of RIAs, it is necessary to provide investors with the opportunity to participate in the ownership of exclusive rights to RIAs created with their support, which will allow investors to control the subsequent disposal of exclusive rights to such RIAs, directly participate in the licensing processes and receive remuneration for their use.The purpose is to develop theoretical provisions that form the basis for the development of legal regulation ensuring the observance of investors' rights as participants in relations related to the creation and use of RIA.Objectives: to identify the peculiarities of registration of investors' rights when they participate in relations related to the creation and use of RIA with the attraction of investment funds; to develop proposals aimed at improving the legal regulation of relations between investors, persons organizing the creation and use of RIA, authors and right holders for various cases of organization of investment activity in the field under consideration.Methodology.
