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 this resource with 2 unique external prefixes.

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier A01M1/026 is used to demonstrate the providers available for Cooperative Patent Classification. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.
