While the United States has held the lead in the percentage of AI repository publications in the world since 2011, China is catching up while the European Union plus the United Kingdom’s share continues to drop (Figure 1.1.20). In 2021, the United States accounted for 32.5% of the world’s AI repository publications—a higher percentage compared to journal and conference publications, followed by the European Union plus the United Kingdom (23.9%) and China (16.6%).

This section draws on data from CSET and 1790 Analytics on patents relevant to AI development and applications— indicated by Cooperative Patent Classification (CPC)/ International Patent Classification (IPC) codes and keywords. Patents were grouped by country and year and then counted at the “patent family” level, before CSET extracted year values from the most recent publication date within a family. Overview Figure 1.1.22 captures the number of AI patents filed from 2010 to 2021. The number of patents filed in 2021 is more than 30 times higher than in 2015, showing a compound annual growth rate of 76.9%.
