edition | 51 | Effective dates: |
main-classification | 51 | Format for all IPC is space-filled to 4-characters at main group: ANNA^^nn/n[...]. See XML example above. |

linked-indexing-code-group | 51 | Indexing codes are used in association with classification symbols to provide technical information. Their format is similar to classification symbols, but they employ a colon in place of the slash. For example: ANNAnnnn:n[...]. Linked indexing codes show which classification symbols the indexing code is associated with. See Review of the Hybrid Systems in the IPC for more information. |
unlinked-indexing-code | 51 | Unlinked indexing codes are similar to linked indexing codes, but are not linked to an associated classification symbol. |

As of 2015, the USPTO has transitioned from using the over 100-year-old U.S. Patent Classification (USPC) system to the Cooperative Patent Classification (CPC), a new classification system jointly developed with the European Patent Office (EPO). The USPTO currently only uses CPC for classifying new utility patent documents; however, it will continue to use U.S. Patent Classification for classifying design and plant patents. |

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 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:
| 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.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:
