How much is the patent agent's affiliation for one year?

Patent agents are affiliated with 1500 yuan to 2000 yuan a year. According to relevant information, the state cracked down on illegal affiliation, and patent agency is a technical service related to patent law. Because patent application requires sufficient knowledge of patent law, most small and medium-sized enterprises and individual inventors do not have the professional knowledge of patent application and need to entrust patent agencies to write and apply for patents.
