20.6.4 PATDPA
Search is possible by the names of Inventors (/AU, /IN, /INC, /INO, /INA), Patent Assignees (/CS, /PA, /PAC, /PAO,
/PAA) and Agents (/AG). The individual fields are assigned like this (shown here for the Patent Assignee, basically the
same for the Inventor fields):
/CS, /PA: Super-field of /PAC and /PAO
/PAC: Name of the current assignee
/PAO: Name of a former assignee
/PAA: Country, postcode, place of the assignee
In PATDPA a mixed index is used for the Inventor fields and a mixed index with interpretation of the search query for
the Patent Assignee fields (implied (S) proximity). Additionally, every name is entered in a number of different variations,
one of which is normalized, i.e. special characters, such as comma, hyphen, etc., are removed:
=> E WIDER/IN
E1 4 WIDENT ALAIN/IN
E2 2 WIDENT PIERRE/IN
E3 19 --> WIDER/IN
E4 1 WIDER BERNHARD/IN
E5 1 WIDER CHARLES/IN
E6 1 WIDER CHARLES DIPL ING/IN
E7 1 WIDER GERHARD/IN
E8 2 WIDER GERHARD DR/IN
E9 1 WIDER GERHARD PD DR/IN
E10 5 WIDER HANS WILHELM/IN
E11 2 WIDER HANS WILHELM DIPL ING/IN
E12 1 WIDER HARMUT/IN
In the /INC and /PAC fields EXPAND shows all special characters, the country, postcode, and place:
=> E BOSCH/PAC 6
E1 1 BOSCAROL PRODUCTION S.R.L. (*IT 39100 BOLZANO)/PAC
E2 9 BOSCATO/PAC
E3 60800 --> BOSCH/PAC
E4 1 BOSCH & NOLTES APPARATEN BNA B.V. (*NL PURMEREND)/PAC
E5 1 BOSCH & SCHOERLE (*DE 7000 STUTTGART)/PAC
E6 2 BOSCH & SOHN FABRIK MEDIZINISCHER APPARATE (*DE 7455 JUNGING
EN)/PAC
E7 1 BOSCH + SOHN FABRIK MEDIZ. APPARATE GMBH & CO (*DE KG, 7455
JUNGINGEN)/PAC
The expression in brackets including the place can be searched together with the name as a phrase ("..."), or the
respective E number can be used. If single words from the name or place are to be searched then the place must be
searched in the /INA or /PAA field respectively, linking the search fields by (S) proximity:
=> S BOSCH/PA (S) STUTTGART/PAA
62591 BOSCH/PA
104144 STUTTGART/PAA
L22 53834 BOSCH/PA (S) STUTTGART/PAA
Postcodes or a range of postcodes can also be searched:
=> S DE70!!!/PAA
L23 58456 DE70!!!/PAA
A mixed index is also used in the /AG (Agent) field. If more than one part of the name is entered (S) proximity is used
automatically. To obtain a complete result it may be necessary to explicitly use AND to link parts of the name.
As the place name is entered in a number of different ways (see example below) a search with the place should be
done only with the E numbers obtained by EXPAND:
