Products recently need better and more complex technologies than they used to. In addition, companies can not afford to research and develop new technologies or scientific theories because companies face fierce competition. Therefore they need to collaborate with other organizations, including not only other companies but research institutes. However, the collaborations have costs to take over boundaries of organizations. This paper reveals which categories of technologies Japanese companies tend to collaborate in, and the productivity of inventors in organizations. The following facts were obtained. (1) The highest ratios of joint applications between companiess and research institutes are in "chemistry and metallurgy", "commodities" and "physics" in that order. (2) Companies tends to choose research institutes as joint-applicants instead of other companies over collaborating with other companies. (3) The experience of inventors' joint-applications between companies does not affect inventors' productivity, but the experience between companies and research institutes does affect their productivity. (4) In a field where inter-organizational joint-inventions provide some advantages to inventors, inventors' experience of inter-organizational joint-inventions tends to their acquisition of experience.
