Outline of Final Research Achievements

We study joint-applications on patent data of Japan and the United States. Inventor teams show better performance than solo inventors. Repetition of collaboration by the same teams show degradation of performance. Firm teams show worse performance in repetition than inventor teams. If a team publishes a patent with high impact, the team tend to have a lot of consecutive works. If a member who repeated a lot of works in the same team moves to a new team, the inventor shows better performance than the other members who stay in the team with a lot of works. We find establishments that apply for patents aggregate in 80 km and joint applications between establishments aggregate in 100 km.
