Research on the Classification Evaluation of Patent Quality and Empirical Test

Patent quality has a decisive position in national intellectual property development strategy. Evaluating patent quality objectively and scientifically, is important to promote the transfer of patent technology and achievements, and enhance the country's independent innovation capability. According to our review of the literature on the evaluation standards of patent quality, we conclude that the current evaluation for the patent quality mainly takes "three characteristics of genetically patent" as the unified standard. However, because the evaluation standards ignore patent technology to some extent, which is the essential characteristics of a patent, the standard is difficult to accurately measure regarding the level of patent quality. In this study, based on patent technical perspective, combined with the classification methods in technology and a contemporary system of science and technology, we divide patent into three types,: basic-type patent, technological patent and applied-type patent. Next, we further analyze the different evaluation standards of patent quality under these three levels based on the characteristics of three types of patents. Next the scientific nature of the classification evaluation index of patent quality from the perspective of empirical research is investigated, which can provides a certain basis and reference to construct a scientific and reasonable evaluation index system and improve our country's evaluation standard of patent quality.
