Rock disintegration is one of the most important technological operations in the production of crushed stone, which is widely used in the construction of roads and railways, buildings, structures, hydraulic engineering facilities, bridges, tunnels, the production of concrete, asphalt, dry building mixes, and other objects and products. In recent years, research has been actively conducted to improve the processes of rock disintegration by reducing energy intensity and improving the quality of disintegrating technologies and equipment. Moreover, developers and inventors are actively patenting the results of their intellectual activities in the field of promising types of new intellectual property for high-potential technologies and equipment for producing high-quality crushed stone. This fact indicates that the problems of improving the quality and efficiency of technologies and disintegrating equipment, in particular crushers for obtaining crushed stone, have not been solved yet. All this necessitates the synthesis and patenting of new market-competitive technologies and equipment for obtaining crushed stone by disintegrating rocks. In this regard, the authors of this work carried out research aimed at building a knowledge base in the field of patenting technologies and crushers that ensure the production of crushed stone for the construction of roads and railways, buildings, structures, hydraulic engineering facilities, bridges, tunnels, the production of concrete, asphalt, dry mixes, and other objects and products. The research also included the categorization of the main areas of patenting in this field. This involved using the method of system analysis performed based on the results of patent information search, collecting and systematizing the information. The current state and trends of patenting in the field of rock disintegration are identified, the main goals (effects) of patented intellectual property are defined. The article presents the most noteworthy patents collected during the building the knowledge base.
