3. Important Points on Filing Application of AI-related Technologies in Japan
In view of recently added Cases 37-40 related to inventive step, it is likely that an invention in which a process usually performed by humans is replaced to be performed by an AI like in “Case 37” is not regarded to have an inventive step.
On the other hand, in order for an AI-related invention to be recognized to have an inventive step as in “Case 38,” “Case 39,” and “Case 40,” it is required that characteristic features of the AI such as processing steps, learning method, data configuration used, etc. were not publicly known or common general knowledge as of the filing, and that an advantageous effect over a cited reference is attained.
Further, also in the case examples previously added in 2019 (Cases 33-36), an invention which merely uses an AI for estimating output data from input data, an invention which merely systematizes human tasks by using an AI, and an invention in which a change of training data used in learning is a combination of known data and no significant effect is recognized are judged to lack inventive step.
Thus, in order to acquire patent right for AI-related technologies in Japan, it should be noted that an invention is required to have a novel feature, such as AI processing steps, learning method, data configuration used, etc., and to attain an advantageous effect over publicly-known techniques by the feature, not to merely use an AI to perform a publicly-known process or merely use publicly-known data in an AI.

3. Important Points on Filing Application of AI-related Technologies in Japan
In view of recently added Cases 37-40 related to inventive step, it is likely that an invention in which a process usually performed by humans is replaced to be performed by an AI like in “Case 37” is not regarded to have an inventive step.
On the other hand, in order for an AI-related invention to be recognized to have an inventive step as in “Case 38,” “Case 39,” and “Case 40,” it is required that characteristic features of the AI such as processing steps, learning method, data configuration used, etc. were not publicly known or common general knowledge as of the filing, and that an advantageous effect over a cited reference is attained.
Further, also in the case examples previously added in 2019 (Cases 33-36), an invention which merely uses an AI for estimating output data from input data, an invention which merely systematizes human tasks by using an AI, and an invention in which a change of training data used in learning is a combination of known data and no significant effect is recognized are judged to lack inventive step.
Thus, in order to acquire patent right for AI-related technologies in Japan, it should be noted that an invention is required to have a novel feature, such as AI processing steps, learning method, data configuration used, etc., and to attain an advantageous effect over publicly-known techniques by the feature, not to merely use an AI to perform a publicly-known process or merely use publicly-known data in an AI.
