摘要

Japanese companies obtain numerous patents in Japan. However, half of these patents are not used according to the survey of Japan Patent Office. The survey shows 30% of patents are blocking patents which are included in unused patents. In this study, we conducted an investigation through documentary analysis and questionnaires to determine the reason for the behaviour of Japanese companies. The result of our research showed that Japanese companies register patents to thwart competition as an R&D strategy and get a first mover advantage.
