介绍了一个新的基于向日本专利局提交的专利申请的综合专利数据库。我们介绍了该数据库的建设方法,IIP专利数据库,它的基本特征,我们讨论了日本专利的最近历史。我们还使用OECD专利族信息来识别美国同行,将该数据库中日本专利的引用模式与在美国注册的相同专利的引用模式进行比较。我们在这两个国家发现了类似的模式,尽管在日本,引用是由专利审查员提供的,而在美国,很大一部分引用是由发明人提供的。
A new comprehensive patent database based on patent applications filed with the Japanese Patent Office is described. We present the methodology for the construction of this database, the IIP Patent Database, its basic features and we discuss the recent history of patenting in Japan. 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.
