JPO – CNIPA Comparative Study on AI-related inventions

In recent years, there have been active research and development of Artificial Intelligence (AI)–related technologies which have resulted in significant increases in AI-related patent applications. This represents the importance of demonstrating the current examination practices for AI-related inventions at each office.

Based on these circumstances, the JPO and the China National Intellectual Property Administration (CNIPA) have jointly conducted a comparative study on AI-related inventions to illustrate the similarities and differences in examination practices to AI-related inventions at both patent offices.

The JPO and the CNIPA have published the report of this comparative study below.

Please note that the focus of this comparative study is on the examination practices for AI-related inventions.

Additionally, the results of this comparative study are not legally binding on either patent office.
