The Cooperative Patent Classification (CPC) is a patent classification system, developed jointly by the European Patent Office (EPO) and the United States Patent and Trademark Office (USPTO). It is based on the previous European classification system (ECLA), which itself was a version of the International Patent Classification (IPC) system. The CPC patent classification system has been used by EPO and USPTO since 1st January, 2013.

Pattern for Local Unique Identifiers

Local identifiers in Cooperative Patent Classification should match this regular expression:
^([A-H,Y]|[A-H, Y]\d{2}|[A-H, Y]\d{2}[A-Z]|[A-H, Y]\d{2}[A-Z]\d{1,3}|[A-H, Y]\d{2}[A-Z]\d{1,3}(\/)?\d{2,})$

Example Local Unique Identifier

A01M1/026   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Cooperative Patent Classification should match this regular expression:
^cpc:([A-H,Y]|[A-H, Y]\d{2}|[A-H, Y]\d{2}[A-Z]|[A-H, Y]\d{2}[A-Z]\d{1,3}|[A-H, Y]\d{2}[A-Z]\d{1,3}(\/)?\d{2,})$

Example CURIE

cpc:A01M1/026

The metaregistry provides mappings between the Bioregistry and other registries. There are 4 mappings to external registries for cpc with 2 unique external prefixes.

Providers are various services that resolve CURIEs to URLs. The example CURIE cpc:A01M1/026 is used to demonstrate the provides available for cpc. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
