Can the public access the CPC system for patent searches?
Yes, the Cooperative Patent Classification (CPC) system is accessible to the public for patent searches and classification purposes. The MPEP 905 explicitly states:
“CPC is jointly managed and maintained by both offices and is available for public search for classification.”
This public availability enhances transparency in the patent process and allows inventors, researchers, and patent professionals to utilize the same classification system used by patent examiners, facilitating more effective prior art searches and patent analysis.
