To be a patent, you must know the law. As a science and engineering student, I suggest you get a master's degree in law when you graduate. The difference between LLM and LLM is that many students are non-law majors, and their admission scores are lower than those of LLM. Generally, schools with law majors recruit master of law. If recommended, the louder the school brand, the better. For example, Peking University, China Renmin University and China University of Political Science and Law all provide good legal education.
