Is it useful to review the examination results of patent agents?

It's no use reviewing your grades. The reexamination of patent agent's examination results can't guarantee that it can change the examination results, and the result of reexamination will be affected by many factors such as marking standards and examination difficulty, so reexamination is useless. Patent Agent Examination is a professional qualification examination sponsored by China National Intellectual Property Administration, which aims to select professionals with the necessary knowledge and skills for practicing.
