Japan’s Top Court Says AI Cannot Be Named as a Patent Inventor

Japan’s Supreme Court ruled that artificial intelligence cannot be listed as an inventor on patent applications, reaffirming that only humans can hold that legal status under Japanese patent law. The decision adds to the global debate over whether patent systems should adapt to AI-driven innovation or preserve human inventorship as the standard.

The ruling is significant for major technology markets because it reinforces a legal boundary that affects multinational patent filing strategies, especially in AI, software, and automation-related inventions. It is also likely to influence future policy discussions in other countries weighing similar questions about AI-created inventions.
