Objective: to study features of intellectual property protection mechanisms on the example of drugs for the treatment of rare (orphan) diseases.Material and methods. Analysis of pharmaceutical market data was performed with the DSM Group analytical database. The approach proposed by the Russian Federal Industrial Property Service was used for creating patent landscape. The method supposes conducting a patent search and analysis of the documents found for date of filing, office (country) of filing, applicant, as well as analysis of the patent activity (dynamics) for the subject, in this case, for orphan drugs having a defined structure.Results. We proposed the complex conclusions to increase national drug safety. Intellectual property limitations for importing countries such as data exclusivity, do not allow to reproduce clinical trials, which leads to non-disclosure of medical data to all parties – medical society and patients, all other market participants, including local pharmaceutical producers. Current intellectual property restrictions conceal crucial data from medical and patient society and other market players and affect accuracy of diagnosis and treatment. Along with outstanding cost of new therapies it causes enormous budget burden for the healthcare system and prevents the introduction of objective criteria in the appointment and use of medicines. Prior to the approval and submission of the registration certificate by the regulatory authority, it is necessary to establish reasonable marginal prices, to form a sufficient set and volume of clinical guidelines and to determine in advance the sources of financing and mechanisms of integration into the national system of drug provision.Conclusion. The introduction of drugs for the treatment of rare diseases into circulation leads to a sharp increase in the burden on the budgets of the healthcare system at all levels. Current restrictions and obligations in the field of intellectual property rights protection, the degree of disclosure of medical data in the process of registration and admission to the market require significant changes to the traditional system of drug provision and the system of placing state orders, as well as the introduction of new regulatory mechanisms (for example, compulsory licensing or producing individual dosage forms in pharmacy organizations), contributing to the development of the local pharmaceutical industry and providing the national health system with the necessary volume of drugs with a sufficient level of quality and safety.
