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 patent applications until 2021 as follows.

  • In addition to AI Core Invention (FI: G06N), we defined "AI-related Invention" as an AI-applied invention in which AI is applied to various technical fields. Since new FIs began to be assigned in January 2023, the figures may differ from those published until last fiscal year.
  • The number of domestic applications for AI-related inventions has been increasing since 2014, with approximately 9,000 applications filed in 2021. The number of applications for AI-related inventions characterized by AI core technology (those classified into G06N as FI) was approximately 2,700 in 2021, and is still increasing, although the growth has slowed somewhat (Figure 1).
  • In recent years, among deep learning techniques, especially generative AI such as ChatGPT has not only been the subject of evaluation on various tasks in academia, but also been the subject of social discussion, and is expected to have an impact on future AI-related inventions.
  • As the main classification of AI-related inventions, G06T (image processing) is the most common, other than G06N (AI core technology). The number of technical fields that can be grouped under "Others" is also on the rise, suggesting that the application of AI technology is expanding (Figure 2).
  • The number of applications for AI-related inventions referring to CNNs, RNNs, or LSTMs has been increasing since 2014. On the other hand, the number of applications for AI-related inventions referring to deep reinforcement learning has remained flat in recent years. In addition, the number of applications for AI-related inventions referring to transformers has been on the rise, surpassing that of deep reinforcement learning in 2020 (Figure 3).
  • Applications for IPC: G06N (AI core technology) are on the rise in all five IP offices. In particular, the numbers in the US and China are outstanding. Therefore, it can be said that the US and China are the major application destinations in five IP offices (Figure 4).
