        Effects of early patent publication on knowledge dissemination: Evidence from U.S. patent law reform

        Okada, Yoshimi :Sadao Nagaoka
        『Information Economics and Policy』 (2020/01/25)

        In order to assess effects of early publication of patent applications on the dissemination of the disclosed technological knowledge, this study examines the impacts of the 18-month pre-grant publication system introduced in the United States in 2000. It focuses on the variations of the applicant non-self-citations driven by the actual…

              Making the patent scope consistent with the invention: Evidence from Japan

              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…

                特許権は、占有ができず目に見えない「発明」という技術情報を保護する排他権であって、独自創作でも他者の権利の侵害となる知的財産権であり、他者の権利の認知困難性という特殊性がある。電気製品や自動車などのように多数のハードウェアおよびソフトウェアを統合して構成される商品では特許侵害を避けることが難しく、硬直的な差止請求権制度の下では産業活動の…

                  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 …

                    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…

                        In order to assess the disclosure function of the patent system, this study examined the impact of the pre-grant publication system introduced in the United States in 2000. Unlike earlier studies, the applicant (inventor) non-self-citations (excluding examiner citations) were used to track knowledge flow. The causal effects of disclosu…

                          An Economic Analysis of Deferred Examination System: Evidence from Policy Reforms in Japan

                          WP#14-05 一橋大学イノベーション研究センター (2014/06/26)

                          We investigate how a deferred patent examination system promotes ex-ante screening of patent applications, which reduces both the number of granted patents and the use of economic resources for examinations, without reducing the return from R&D. Based on a real option theory, we develop a model of examination request behaviors. Exploit…
