Taking into consideration the legal nature of evidence, we analyze the main procedural features of evidence widely used by persons participating in the case when resolving civil cases related to the protection of intellectual rights, such as screenshots of materials posted on Internet sites, electronic messages. We define the general features that characterize the indicated sources of evidence in this category of disputes. We point out, in particular, the objective influence of the procedural rules governing the rules of jurisdiction over intellectual disputes, as well as the substantive rules of Part 4 of the Civil Code of the Russian Federation, on the features of the development and provide evidence for the protection of intellectual rights in court, sources of evidence. We describe the relationship between the concepts of electronic documents, written evidence, and evidence generated through the use of the Internet. When applying general scientific methods of comparative analysis (in relation to certain sources of evidence) and deduction (in relation to the analysis of special norms through the prism of general, basic, main procedural institutions that regulate relations in terms of the legal nature and characteristics of the evidence presentation in the category of cases under consideration), we form the main conclusions in terms of possible options for the development of these procedural institutions. We prove the necessity of the proposed changes for the purpose of the subsequent optimal functioning, action and application of the norms governing the evidence process in this category of cases, the concept of “electronic text evidence” is introduced.
