All kinds of documents can be searched with truncation, e.g.:

Usually EXPAND is recommended.
The numbering of publications is done separately for each document type. This means that:
Documents of different publication levels, although being members of the same patent family, are likely to
have different publication numbers and
Documents of different publication levels having the same publication number are rather unlikely to
belong to the same patent family.
For a clear distinction of document types the document kind code must be specified in addition to the publication
number.
Due to the publication system having changed from a publication of the examined application (with a three
- -grant opposition
period) numbering has been changed for these documents to consecutive numbers starting from 2 500 001 with
the publication kind code B from May 1996.
JAPIO only contains unexamined applications. In World Patents Index all publications of the national patent family
are included in the PI field. The ADT field gives information on which publication relates to which application
number. In INPADOCDB the members of the national family are entered into new publication segments. The
application number can also be used to identify documents based on the same application.
JP documents show the publication number (as illustrated in the above format) and the publication date (including
Emperor and Western years, in Roman characters), B documents show the relevant data of an earlier publication
additionally (code A, T).
20.5.3 Note on KR document numbers
Current Korean publication and patent numbers on the printed documents include a code for the type of
publication (10 = patent, 20 = utility model, 30 = design); this code is not included in the document number format
on STN. The number of digits is different, too.
Example:
Printed Korean number: 10- 2004- 0009844
STN publication number: KR 2004009844 A
20.6 Search by patent kind code
Often it is necessary to use a document kind code together with a patent number, e.g. in legal status searches, or to
restrict the scope of the search to certain types of documents in a subject or SDI search strategy. To do this, the
publication kind codes must be entered in this format:
CCnn
CC Country (Two-letter code)
