We also compare citing–cited patterns of Japanese patents in this database with the citing–cited patterns for the same patents registered in the US, using OECD patent family information to identify US counterparts. We found similar patterns in the two countries, although citation is provided by patent examiners in Japan, while in the US a large share of citations is made by inventors.
