Usually EXPAND is recommended.<br />
The numbering of publications is done separately for each document type. This means that:<br />
Documents of different publication levels, although being members of the same patent family, are likely <strong>to</strong><br />
have different publication numbers and<br />
Documents of different publication levels having the same publication number are rather unlikely <strong>to</strong><br />
belong <strong>to</strong> the same patent family.<br />
For a clear distinction of document types the document kind code must be specified in addition <strong>to</strong> the publication<br />
number.<br />
Due <strong>to</strong> the publication system having changed from a publication of the examined application (with a three<br />
- ost-grant opposition<br />
period) numbering has been changed for these documents <strong>to</strong> consecutive numbers starting from 2 500 001 with<br />
the publication kind code B from May 1996.<br />
JAPIO only contains unexamined applications. In World <strong>Patent</strong>s Index all publications of the national patent family<br />
are included in the PI field. The ADT field gives information on which publication relates <strong>to</strong> which application<br />
number. In INPADOCDB the members of the national family are entered in<strong>to</strong> new publication segments. The<br />
application number can also be used <strong>to</strong> identify documents based on the same application.<br />
JP documents show the publication number (as illustrated in the above format) and the publication date (including<br />
Emperor and Western years, in Roman characters), B documents show the relevant data of an earlier publication<br />
additionally (code A, T).<br />
21.5.3 Note on KR document numbers<br />
Current Korean publication and patent numbers on the printed documents include a code for the type of<br />
publication (10 = patent, 20 = utility model, 30 = design); this code is not included in the document number format<br />
on <strong>STN</strong>. The number of digits is different, <strong>to</strong>o.<br />
Example:<br />
Printed Korean number: 10- 2004- 0009844<br />
<strong>STN</strong> publication number: KR 2004009844 A<br />
