These are the international classifications at the time of publication for documents published before IPCR went into effect (pre-2006).
Element | INID | Description |
|---|---|---|
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. |
further-classification | 51 | Further/secondary classification. Same format as |
additional-info | 51 | Additional information |
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. |

country | Indicates whether the classification code is based on the USPTO classification (US) or on JAPIO FIndex (JP). |
Element | INID | Description |
|---|---|---|
| edition | 52 | Edition of the classification schedule |
main-classification | 52 | The format for all US classes is zero-filled to a 3-character class and 3-character subclass. Characters following those 6 numbers are not zero-filled, and non-significant trailing zeros are removed. There is no punctuation present. Slashes and decimal points can be easily inferred for display purposes. |

| additional-info | 52 | Additional information |
| linked-indexing-code-group | 52 | 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. |

text | 52 | In certain data parsing errors, the structure of the classification as delivered in the raw data cannot be established. In these cases, the raw classification data is output in the child: text. |
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.
