Patent agency needs compound talents, who should know both technology and law. Especially for foreign agents, foreign language knowledge is also essential. I suggest that as the first step, you should learn these two languages well, and you should not only read them, but also speak them, because foreign agents often have to deal with foreign lawyers or clients. Then, we should study the relevant laws in depth. To master the laws of China's intellectual property system, we must also understand relevant laws, such as the general principles of civil law, contract law and so on. Then, if you are a foreign agent in Japan, you have to learn from Japan's intellectual property legal system, otherwise it will be difficult to do well. The United States and Europe basically need to understand.
With the above foundation, you can take the patent agent qualification examination, but undergraduates are not qualified to take the examination. Only postgraduates or undergraduates who have worked for two years can take the examination. The premise must be engineering students. If you are a liberal arts student, sorry, no.
