Abstract: Brain-computer interface and artificial intelligence are key research fields that countries are competing to lay out, and to a certain extent, they represent a country’s scientific and technological innovation and comprehensive strength. To explore the impact of the application of artificial intelligence in the field of brain-computer interface, this paper conducts patent retrieval and analysis based on the IncoPat patent database, and conducts a comparative study on brain-computer interface patents (BCI patents) and artificial intelligence + brain-computer interface fusion patents (AI + BCI patents).Research shows that BCI patents as a whole are developing in an intelligent direction. The integration of artificial intelligence has injected vitality into the development of brain-computer interfaces and is conducive to the future development of the industry. China leads the industry in both BCI patents and AI+BCI patents, but there is still a considerable gap compared with the United States in terms of international market layout, technological influence and some specific technical fields. Research in our country is more concentrated in universities and research institutes, with relatively low participation of technology companies. In contrast, many foreign technology companies rank among the top in terms of the number of patents. India’s rapid development in AI+BCI patents deserves attention. Therefore, China should deepen the integrated development of artificial intelligence and brain-computer interfaces, strengthen patent monitoring and early warning in key regions and directions of brain-computer interface, increase support for key and weak technologies such as implantable electrodes, and further improve the quality and international influence of BCI patents.
