Abstract: Studying the distribution of patents by country, combined with examining the strategy for international protection of intellectual property rights within a single patent portfolio, provides a wealth of information about the spatial distribution of patentable objects. For example, the country where the original application was filed usually represents the country where the invention was developed, while subsequent international applications indicate potentially commercially viable regions to market products or localize production. The most common way to analyze the regional affiliation of patents is to rank countries according to the number of registered patents. A comprehensive approach, including a comparison of the geographical coverage, rights holders and interrelated references between applications, makes it possible to identify the key competencies of scientific organizations and corporations in specific sectors of technology. The article provides an analysis of patent activity in the Russian Federation and worldwide, with the construction of a patent map in the area of developing technologies for pilot long holes to dispose of heavily polluted wastewater from coal plants.
