INPADOC Databases – Enhanced coverage of US citation data
30. Mai 2012
The coverage of US citation data has been extended to include examiner citations for US published applications (US A1 documents). This is a considerable advantage because citations of US documents are now available much earlier and more comprehensive than before. Previously, citations were only made available for US granted patents. Examiner citations of US A1 publications have the attribute PRS (pre-grant search) assigned indicating the source of citation.
