Statistical Analysis of Literature Number of Chinese Artificial Intelligence Patent
Objective:To analyze the Chinese patents related to artificial intelligence published in the China Patent Full-text Database(CNKI Edition)from 2011 to 2022,so as to provide a scientific basis for scientific research departments and research teams to carry out knowledge industrialization.Methods:Statistical analysis is carried out as per the annual distribution,subject distribution,category distribution,discipline distribution,literature classification and other aspects.Results:During these 12 years(from 2011 to 2022),a total of 18323 articles of Chinese patent related to artificial intelligence have been published,and the number of articles published is relatively slow in the first 5 years and increases rapidly in the subsequent 7 years,with the invention patent literature accounting for the highest proportion(65%)among the three categories of patents;and the computer software and computer application literature accounting for the highest proportion(23.75%)among the discipline categories involved.Conclusion:The research and development of Chinese artificial intelligence patents are rapid and interdisciplinary,and the achievements are substantial,and it is suggested to transform the invention patents into actual productivity and increase the patent industrialization rate,thus continuously promoting the scientific and technological innovation and social progress.
