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.
cpc
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,})$
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,})$
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.
