This paper presents a method for analyzing innovation trends through the detection and analysis of patent activity, the identification of new technological capabilities, key modern technologies and inventions. As part of this study, it is proposed to use a method based on structures extracted from the SAO patent corpus. A five-step method has been developed for identifying SAO structures, expanding them, clustering, and also building flow sheets. This approach can be applied to the analysis of technological trends (trend mapping). This map visualizes the development of subclasses of patents identified through cluster analysis and technology over time. In addition to identifying technological capabilities, the described approach can be applied to construct maps to study the trends of competitors. Unlike a trend map developed using all applicants’ patents, this competitor card limits its attention to a single organization. A map for each company visualizes the focus of technology development in the company, allowing for a comparative analysis between companies. Based on this map, the company can identify competitors with additional technologies and understand the technological advantages and disadvantages of the target area.
