Technological complementarity plays an increasingly important role in making strategic decisions regarding the choice of partners to work with as well as for expanding the diversity of innovation activities through the creation of alliances or mergers. Modern quantitative measurements of technology complementarity are largely based on research founded on patent classification codes. However, this approach ignores specific technologies in a particular field and, therefore, the results obtained are only general pointers. It is proposed to develop an approach to the quantitative measurement of the complementarity of enterprise technologies in reliance on statistical machine analysis of the patent array. The aim of the study is to develop a technology for clustering USPTO patent documents and identifying technological complementarity of enterprises based on the comparison of cluster information. The theoretical value lies in the following: the developed algorithms for patent parsing; clustering of the patent array based on the hLDA method; formation of "Enterprises – Clusters (Topics)" matrix; visualization of enterprise connections in a clustered patent space. The practical significance of the research lies in the developed software for identifying technological complementarity of enterprises, the effectiveness of which has been tested on a number of test examples.
