CPCNO indicates CPC Values include:
- CPC: symbols that have been allocated to a document by
- the EPO, discontinued as of week 2019/36
- CPCNO: symbols that have been allocated to a document by
- a national patent office, discontinued as of week 2019/36
- CPCI: CPC-International. CPCI is maintained at the family level. When there has been a change to the CPCI picture for a given family, every member in the simple patent family (i.e., all members with the same family ID) will be updated. When different authorities have allocated the same classification symbol, the CPCI picture for one publication will contain duplicate symbols. Duplicate symbols for one publication will be made unique by a two-letter authority-code, which can be found in positions 41-42 in the CPC.

classification-cpc | 52 | Cooperative Patent Classification. Format is according to WIPO ST. 8. For more information on CPC, see Cooperative Patent Classification in IFI CLAIMS Direct. The full list of CPC codes can be found on the CPC website or the USPTO website. When available, F and L symbols may indicate first and later classifications as in the following example:
The different elements of CPC codes are described in the following table:

combination-sets | Group of CPC symbols that have one base class and one or more subsequent ranked symbols that are linked together to convey special classification information. C-Sets classification is a special classification technique, providing a mechanism for searching combined features that are otherwise not easy to find by single symbols, resulting in more precise and efficient retrieval of technical information from CPC. A C-Set brings together symbols from different groups within the same subclass or from different subclasses, in a certain order.
Example of C-sets presentation in patent documents and in the CPC database:
