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.

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. Furthermore, inventions related to deep learning are rapidly increasing, and in 2017, nearly half of AI-related inventions refer to deep learning in the application documents(Figure 2).
  • As for AI-applied area, the numbers of applications in the image processing and information retrieval fields are particularly high (Figure 3), and the growth rate in control / robotics fields is high.
  • According to filing trends by patent applicants, each of them is using AI for technical fields closely related to their own business (Figure 4).
  • Applications for IPC: G06N are on the rise in the world, with the number in the US and China outstanding (Figure 5).
