Legal status information of applications filed in January 1964 onwards can be searched on the J-PlatPat by using document numbers such as application numbers, publication numbers and registration numbers. In addition, since September 2023, J-PlatPat has enabled users to check the legal status of a patent (in accordance with WIPO standard ST.27) at a glance from the search result list screen and document display screen without searching the progress information.
Alert Service (RSS distribution) to notify of the status information update of designated applications is also available. RSS distribution has been expanded to cover all patent applications from 2021.
