In recent years, there have been rapid AI technological advances which have resulted in significant increases in related patent applications. The China National Intellectual Property Administration (CNIPA) and the Japan Patent Office (JPO) have jointly conducted a comparative study on patent examination cases in the field of AI and formed a study report, with the aim of providing applicants insights into AI-related patent examination criteria and practices.
The report comprises two parts, examination rules and case studies. The part of examination rules elaborately introduces the two offices' examination criteria on subject matter for which patent right shall be granted, novelty, inventive step, sufficient disclosure of the description, and support for claims by the description. The part of case studies selects a total of 16 typical cases, comparing and analyzing the two offices' examination processes and outcomes.
