Revisiting incremental product innovations in the food manufacturing industry: An empirical study on the effect of intellectual property rights

Yoshioka-Kobayashi, Tohru: Tomofumi Miyanoshita: Daisuke Kanama
『Journal of Economic Structures』 （2020/04/20）

The highly competitive and mature food industry has long been process innovation-oriented while largely neglecting product/technological innovation.

Okada, Yoshimi : Yusuke Naito : Sadao Nagaoka
『Journal of Economics & Management Strategy』 Vol. 27 Issue 3 pp. 607-625 （2018/07/31）

It is a crucial function of patent examination to make the patent scope consistent with the contribution of the invention to the state of the art. We assess this function using newly developed data on the scope of Japanese patent applications and grants. We find that the scope was narrowed in two thirds of the grants, both the incidenc…

Contribution of Patent Examination to Making the Patent Scope Consistent with the Invention: Evidence from Japan

Okada, Yoshimi : Yusuke Naito : Sadao Nagaoka
RIETI Discussion Paper 16-E-092 Research Institute of Economy, Trade and Industry (RIETI) （2016/11/29）

Delineating the patent scope consistently with the contribution of the disclosed invention is one of the most crucial requirements for a patent system to promote innovation effectively. Given the incentive of an applicant to set a scope for the patent as broad as possible, an important task of the Patent Office is to narrow it so that …

Global spread of pharmaceutical patent protections: micro evidence from the international equivalents of the drug patents in Japan

Okada, Yoshimi : Sadao Nagaoka
WP#16-07 一橋大学イノベーション研究センター （2016/07/13）

We investigate the global spread of pharmaceutical patent protections as acquired by firms, based on a novel global patent database for all significant medical drugs introduced in Japan. It gives us the propensity of filing and grant rate for each country for the granted patents in Japan. Major findings are the following. Both the fili…

Claim Length as a Value Predictor of a Patent

Okada, Yoshimi : Yusuke Naito : Sadao Nagaoka
WP#16-04 一橋大学イノベーション研究センター （2016/04/07）

The claim of a patent defines the scope of patent right and provides crucial information on patent value. However, most empirical research uses only the number of claims as an indicator of patent value. We show that the breadth of a claim of Japanese patents, measured by the inverse of claim length, has significant explanatory power fo…
