Particulars of the priority fields in the various databases
The PRAI, /PRN field only has data if a foreign priority was actually claimed: USPATFULL, USPAT2,
USPATOLD, IFIPAT
The PRAI, /PRN field does not exist: RUSSIAPAT
The PRAI, /PRN field may contain non-standardized priority numbers: PATDPAFULL, PCTFULL
There is a PRAO, /PRNO field that contains the original (non-standardized) priority
numbers. This field is filled either in addition to the PRAI field or only this field is
the pre-defined display formats:
PATDPAFULL, EPFULL,
PCTFULL, FRANCEPAT,
KOREAPAT, RUSSIAPAT,
FRFULL, GBFULL
In some databases the original application numbers are recorded in the APO field (KOREAPAT, RUSSIAPAT).
These fields are not included in the pre-defined display formats. This may apply to document numbers in
the PNO field too.
20.5 Search by document number
Document numbers (Publication Numbers), just as Application Numbers, can have very varying formats depending
on the patent office, e.g. just a serial number, a number with preceding year, identical with the digit sequence of the
Application Number, etc. Often, to distinguish the publication status within the patent procedure, the Document
Kind Code is specified as well. Examples:
DE 19919951 A1
DE 10 2004 002 764 A1
DE 20 2004 000 023 U1
