Abstract: This research compares and discusses in-house R&D and joint R&D, focusing on the ratio of patent granting and the level of inventive step of the inventions described in patent applications and patents, by using patent information analysis. The result of the R&D study shows that the level of inventive step of in-house inventions increases along with the progress of R&D activities, while the level of inventive step of joint R&D does not increase, but satisfies the company's demand to absorb outside technologies with higher ratio of patent registration, etc. Companies are expected not only to create their own core technologies without joint R&D, but also to define the targeted technologies which can be absorbed efficiently from external partners.

Keywords: joint R&D; in-house R&D; research and development; patent analysis; co-owned patents; patent applications; inventive steps; external technology; external partners; Japan; granting patents; intellectual property.
