Patent is a significant sign of modernizing a country. Protecting patents has been a problem since the Patent Law was conducted in 1949. At initial stage, inventors were unwilling to register patent because that they thought their inventions would not be protected by the Patent system. Until now, there are about 80,000 applications every year. It is clear that the patent system has developed more completely. However, it produced new proplems with us. For instance, the percentage of patent licensing is too law; the examining procedure is too long. Therefore, the patent system still need to be revised. In this research, the author reviewed the patent law and mechanisms on the basis of the five frameworks of administrative law, including Basic Principle, Administrative Organization, Administrative Competence, Administrative Remedy and Administrative Supervision, and literature review. For the purpose of improving Patent system, the researcher suggested that the Patent system should be revised.
