Technology management is important to both companies and nations. Recently, economic competitiveness for both depends on technological prowess. Patents are a representative index of technological competitiveness because a patent document has diverse and detailed information about developed technologies. Hence, patent analysis is an efficient tool for technology management activities such as R&D planning and technology marketing. In this paper, the authors propose a patent analysis method using Bayesian network models. A Bayesian network is a graphical model representing the relationships between variables.
