What are those patent classification systems
Patent classification systems categorize inventions based on their technology. Some older systems include the Canadian (OCPC) and US (USPC) classifications. Most countries now use the International Patent Classification (IPC) system, with some adopting the even more detailed Cooperative Patent Classification (CPC) system. These systems contain hundreds of thousands of entries with definitions to precisely categorize patents.
