Recent Trends in AI-related Inventions

(banner) Recent Trends in AI-related Inventions

August 2021
Patent Examination department (Electronic Technology),
Japan Patent Office

In recent years, Artificial Intelligence (AI) -related technology has shown remarkable development centering on deep learning. Accordingly, AI-related patent applications are increasing across technological fields. As growth of AI-related technology developments and patent applications is expected to continue in the future, the JPO researched the current status of AI related applications in Japan and overseas, and reported the result in July 2019.

This time, the JPO updates the result based on published patent applications until April 2021 as follows.

Summary of the report (See body of the report for details.)

  • We define 1; AI core invention (FI: G06N) and 2; AI-applied Invention as "AI-related invention".
  • The number of domestic applications for AI-related inventions has increased rapidly since 2014 due to the impact of the third AI boom (Figure 1). In that boom, machine learning including neural networks plays its leading role. The number of inventions related to machine learning or neural network is increasing (Figure 2).
  • As for AI-applied area, the numbers of applications in the image processing and business fields are particularly high (Figure 3), and the growth rate in control / robotics fields is high.
  • Applications for IPC: G06N are on the rise in the world, with the number in the US and China outstanding. Especially in China, the number of applications is doubled again in this year (Figure 5). The rate of increase in the number of application filed in Korea is also high.
