A study on the technology convergence of artificial intelligence through patent analysis

Abstract

Since the patents contain original information on technology, it can investigate changes in technology and the convergence phenomenon with co-classification analysis of IPC (International Patent Classification) code indicating the technology group of the patents. In this research, we analyzed the changes of technological convergence for artificial intelligence (AI) technology, which was recently studied actively. We collected Korean patent documents using KIPRIS (Korea Intellectual Property Rights Information Service) and analyzed social networks of IPC codes of the patents. Additionally, the convergence types could be reviewed using network centrality and clique analysis. AI technology mainly focuses on data processing systems (G06F, G06Q). Although there were many technologies that utilized telecommunication services (H04) in the past, technologies related to computing, calculating and counting (G06) have been mainly used in recent years. We also could find that there was a change in the technology area where AI mainly focused
