PatentScope Has JP Data

Japanese patent documents are now available in PatentScope. The JP national collection is the 29th added to the system and includes more than 3 million records from January 2004 through July 2012. New data will be added weekly.

JP documents can be searched by number or IPC classification. But in order to search by name or keyword, one has to use PatentScope's Cross Lingual Expansion search mode.
