AI, as a frontier technology, is attracting more and more attention in China. The CICS-CERT and the Electronic Intellectual Property Center of the MIIT have been releasing annual AI patent analysis reports since 2018. Of the reports released by them, the 2021 report “Analysis of China’s High-Value Patents and Innovation Drivers of Artificial Intelligence” takes the quality of AI patents as an important component of analysis to make a quantitative summary of the current development trend of AI technology patents in China. The report pointed out that with the iterative development of technology and the gradual improvement of the industrial ecology, China’s AI patents continued to maintain an explosive growth trend. As of September 2021, China's total number of AI patent applications amounted to 909,401 with 253,811 patents granted. Baidu, Tencent, China’s State Grid, Huawei, and Alibaba were found to be the top companies filing the most AI patent applications and achieving the best quality for their AI patents. Baidu, specifically, topped the list for the fourth consecutive year, with 13,007 patent applications filed and 3,652 patents granted.

The report also pointed out that AI technology was developing in an all-around way in China, with 14 technologies categorized into 4 modules, i.e. general-purpose technology (deep learning, knowledge graphs, smart chips, and quantum computing), key-field technology (natural language processing, intelligent speech, computer vision, and intelligent recommendation), applied technology (smart city, intelligent map, smart healthcare, and intelligent driving), and foundational technology (big data and cloud computing). Massive progress has been made in the 4 modules. General-purpose technology has been subject to biggest innovation. Applied technology, of all applied technologies, has seen the highest number of patents filed and granted. Intelligent driving patents figure predominantly in the module of AI applied technology. Deep learning, as a branch of the general-purpose technology module, is growing the fastest. Baidu has the highest number of patent applications in various fields, including deep learning, intelligent driving, natural language processing, intelligent speech, knowledge graphs, intelligent recommendation, intelligent map, computer vision, smart healthcare, and smart city, showcasing a full array of innovative capabilities. The report was highly assertive about the aggressive investment policy on basic, cutting-edge, and disruptive AI research and patent portfolios of Baidu and some other domestic companies.


At present, China is in a critical stage of transition from high-speed development to high-quality development. In such a context, the report “Analysis of China’s High-Value Patents and Innovation Drivers of Artificial Intelligence” focuses on the theme of the times, i.e. high-quality development, formulating an innovative evaluation system to identify high-value AI patents. A list of Chinese companies rated and ranked was formed with the application of the evaluation system in the report. Baidu topped the list again with a score of 92.24, followed closely by Tencent and Huawei. In addition, the report also provided a statistical analysis of the results of the AI category of the China Patent Awards, recognizing Baidu as China’s best AI company in terms of number and rank of the awards it received. In June 2021, Baidu won a Gold Medal for an AI patent, China’s first Gold Medal for AI interactive technology.


With such a scientifically sound patent evaluation system in place, each patent was evaluated individually and the competitiveness and impact a patent holder obtained with all the patents it owned was also measured. Its competitiveness and impact was measured in terms of technology, market, industry, society, and policy. The evaluation results showed that a large number of high-value AI patents that Baidu had meticulously created over the years not only improved the company’s own technical strength and industry status, but also produced an exemplary role in promoting the high-quality development of China’s entire AI industry and boosted the prosperity of related industries.
