Abstract: Today's society is entering the era of information big data, and scientific research such as artificial intelligence and human-computer interaction has become a research hotspot in the field of information technology innovation. Among them, brain-computer interface technology is the focus of interdisciplinary research in medicine, science and engineering. In order to comprehensively explore the technological development of global BCI in the medical field, this study carried out patent analysis of BCI in the medical field based on PatSnap patent database analysis platform. Based on the patent data, the relevant patent documents of brain-computer interface applications in the medical field from 2003 to 2023 are mined, and the application trend, application region, technical field and main applicants are visually analyzed. The results show that brain-computer interface has gone from scientific theoretical research to the stage of technological explosion; The United States has the largest number of patent applications for brain-computer interfaces in the medical field, and China still needs to enhance the research and development and innovation capabilities of core technologies in this field. A large number of companies around the world have increased their investment in technology research and development in the field of brain-computer interface, and universities and scientific research institutions have also actively carried out research and application of key technologies. However, issues such as ethics and safety, high research and development costs, have a certain impact on the development trend of patents. By systematically analyzing the patent information of global BCI technology in the medical field, this paper reveals key information such as its technological development trend, core technology layout, industry leaders and competitive situation in the medical field, providing reference for solving the problems to be faced in the development and application of BCI technology. New programs have been contributed to the promotion of key technology innovation and the development of high-quality talent training strategies.
