We use forward citations to measure the value of the patents. Adjusting the heterogeneity of propensity to cite by subsequent patents in 19 major biomedical fields per year, we employ panel regressions controlling a fixed effect of the first assignee. Our main findings are as follows: (1) patents filed by a corporation and joint applications by corporations are highly valued; (2) if a corporation is the first assignee, a patent with a government co-assignee is highly valued; (3) although the value of government patents is not very impressive, it has risen since the pro-patent policies; and (4) there is no significant change in the value of university patents before and after the Japanese Bayh-Dole Act.

This paper examines the value of Japanese biomedical patents filed for 1991.2002, both before and after the introduction of the TLO Act in 1998 and the Japanese Bayh-Dole Act in 1999. We use forward citations to measure the value of the patents. Adjusting the heterogeneity of propensity to cite by subsequent patents in 19 major biomedical fields per year, we employ panel regressions controlling a fixed effect of the first assignee. Our main findings are as follows: (1) patents filed by a corporation and joint applications by corporations are highly valued; (2) if a corporation is the first assignee, a patent with a government co-assignee is highly valued; (3) although the value of government patents is not very impressive, it has risen since the pro-patent policies; and (4) there is no significant change in the value of university patents before and after the Japanese Bayh-Dole Act.
