In this paper, we propose an efficient method of technical structure analysis of FPGA development using network analysis. Recently, with the reform of the industrial structure called “Industry 4.0” and the explosive expansion of the application area of AI (Artificial Intelligence), the demand for computing power in edge devices is increasing. For these backgrounds, the acceleration by FPGA is focused on the industry. Hence, in this paper, we analyze the technology development trends of a significant FPGA supplier. As analytical data, we employ patents obtained by the company in the U.S. We focus on the classifiers in the patent information. We create graphs by classifiers and analyze their clusters. From the results of extracting graph features by the proposed method, key technology areas and their transitions are revealed in the technology development of FPGA suppliers.
