The following table shows the ranking of Applicants in Japan. The ranking is based on the following conditions.
- Technical field: AI (artificial intelligence, machine learning, deep learning, etc.)
- Status: Japanese granted patents in 2018 (registration date).
- Count: The number of patents filed by each applicant was counted.
In the patent search, it was confirmed that a high-accuracy population (i.e., a population not including non-relevant fields) of patents was obtained. Subsequently, the population was used to create the table.
