Based on the incoPat patent index database, a study was conducted on the global competition landscape of AI chips and lithography technology, focusing on four key dimensions: year, region, applicant, and patent value. The results indicate that from 1990 to 2023, patent applications for global AI chips and lithography technologies have been rising annually. China plays a significant role in terms of patent applications and the sources of patent inventors for AI chips and lithography technology. However, in terms of applicant distribution and patent value, it has not yet ranked among the leaders. There is a gap between China and the international advanced level in patent concentration and core technological competitiveness. In order to improve its position in global competition, it is suggested to strengthen its patent strategy and technological innovation.
