Where possible historical gaps in the coverage of application and priority data have been filled using original data from DE, EP, US, PCT and JP sources. This additional data is available within the APTS and PRTS fields in combination with the application and priority information which has been recorded in DWPI over time (AP and PRN fields). AP and PRN do not contain this additionally sourced data.
