Abstract

This paper aims to contribute to estimating the value of a patent by explaining the unobservable attributes of patent quality using observable patent citation indices. The paper first constructs patent citation data and identifies firm, university, and research institute among assignees, and then tries to explain attributes of patent quality using backward citation indices. Backward citation indices carrying information about technological sources which a given patent is based on turn out to be good predictors of forward citation indices carrying information about attributes of patent quality. Finding the functional relationships between attributes of patent quality and backward citations will lead to the improved estimation and prediction of patent value. It is found out that backward citation indices are strongly correlated the technological diversity of a patent. The paper also suggests that with whom an organization chooses to collaborate affects the attributes of patent quality.

본 연구는 특허의 질적 특성을 관측 가능한 특허의 인용지표로 설명함으로써 특허가치 추정모형에 기여하는 것을 목표로 한다. 본 연구는 기업, 대학, 연구소가 한국특허청에 출원한 특허를 대상으로 전후방 인용자료를 구축하였다. 특허의 원천측면을 반영하는 후방인용 지표들이 후속특허에 의한 활용측면을 반영하는 전방인용 특성들을 잘 설명하는 것으로 나타났다. 전방인방 지표와 후방인용 지표 간에 존재하는 함수관계는 특허가치에 대한 추정, 예측모형을 더 정교화하는데 기여할 것이다. 후방인용 지표들은 특허 자체가 갖는 기술범위를 잘 설명하는 것으로 나타났다. 기술협력의 일방에게 기술협력의 상대방이 누구인지도 중요하였다.
