Jump to navigation Jump to search
CPC stands for the Cooperative Patent Classification, an international standard for technology categorization of patent documents.
The items begin with a letter, followed by a digit, then other letters and numbers and usually a / in there.
- The Cooperative Patent Classification (CPC) is a patent classification system, which has been jointly developed by the European Patent Office (EPO) and the United States Patent and Trademark Office (USPTO). The CPC is substantially based on the previous European classification system (ECLA), which itself was a more specific and detailed version of the International Patent Classification (IPC) system."
