What is the Cooperative Patent Classification (CPC) system?
The Cooperative Patent Classification (CPC) system is a joint classification system developed by the USPTO and the EPO. As mentioned in MPEP 901.07:
“The Cooperative Patent Classification (CPC) is a bilateral system jointly developed by the USPTO and the EPO, which has been jointly managed since January 1, 2013.”
Key features of the CPC system include:
- A harmonized classification approach between the USPTO and EPO
- More detailed and comprehensive classification than previous systems
- Regular updates to reflect technological advancements
- Improved searchability and accessibility of patent documents
The CPC system helps patent examiners and researchers more effectively search and categorize patent documents across different patent offices.
