CPC Thesaurus based on official CPC Scheme

21. October 2014

The CPC thesaurus feature available in STN patent databases is now based on the official CPC scheme, known as “the interleaved presentation of the CPC”. This presentation is the official and only presentation of the CPC scheme since September 2014. The major difference to the original scheme is that CPC codes of the 2000 series (e.g. A61K2039/505) are now integrated in the context of existing IPC main groups:

. A61K0039-0001/CPC
. A61K0039-0002/CPC
. A61K0039-0003/CPC
. A61K2039-505/CPC
. A61K2039-51/CPC
. A61K2039-54/CPC

Search tip for broad CPC searches:
Users who would like to include CPC codes of the 2000 series in a main group search should use the thesaurus functionality +NT to search the complete hierarchy, e.g.

=> S A61K0039-00+NT/CPC

The search statement A61K0039/CPC alone does not include the CPC codes of the 2000 series.
