In the context of promoting the high-quality development of intellectual property rights,it is of great significance to objectively and accurately evaluate the quality of patents to improve the quality of innovation and help China achieve self-reliance in high-level science and technology.Based on the patents in the field of medical devices in China from 2014 to 2023,this paper uses social network analysis to study the development trend of patents in the field of medical devices in China from three aspects of knowledge network,cooperation network and citation network,and evaluates the quality of patents based on the network structure.The study finds that the fields of medical imaging,surgical robots and rehabilitation devices have high innovation vitality and wide spread of technical knowledge.The results of patent quality evaluation show that the cooperation network index plays a major role in the quality evaluation,and the quality of patents in the field of medical devices in China is uneven,and there is a large space for progress.
