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…

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 …

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

Yamauchi, Isamu : Sadao Nagaoka
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…
