20.2 Search by country
Types of search
When searching by country (Priority Country /PRC, Application Country /AC, Publication Country /PC, Designated
State in the international or European procedure /DS, Related Document Country /RLC, Referenced Patent Country
/RPC) one should always use the two-letter country code. The query should be linked directly with a further query
(e.g. limit of period), otherwise, the system limits will be reached very fast in some databases
(INPADOCDB/INPAFAMDB) and frequently cited countries such as Japan (JP).

L12 24 L11 AND DE/AC
The fully spelled name of the country is also available in the databases, but, depending on the individual databases,
various languages are used (English, German).
To cover the patents of a particular country in addition to the Publication Country, /PC, the Designated State of the
international and European procedure, /DS, must also be searched. There is a Super-Search-Field, /PCS, covering just
these fields.

Note that the applicant of a PCT or EP application does not have to make his final decision about the designated
states at the time of application. If the designated states are changed later this information can be found for
example in the legal status in INPADOCDB/INPAFAMDB.
In INPADOCDB/INPAFAMDB the fields AC.WO and PRC.WO can be used to get the number of applications of a
particular country.

20.2.1 Note on Designated States
The Designated States in PCT applications are entered in different sections RW and W. The countries after the code
W (World) are PCT designations to national offices. The countries after the code RW (Regional World) are
designations to a country via a regional office (EPO, EAPO, ARIPO, OAPI). For EP applications there is only the code R
(Regional).
