For decades, patent law operated on a simple assumption that if someone built something, the person gets to be credited for the idea. However, AI systems started generating ideas that humans had not thought of on their own, and that assumption quickly cracked.
The World Intellectual Property Organization has now looked at how countries around the world responded to that crack and the answer is nearly unanimous. An AI cannot be listed as the inventor on a patent. But understanding why that answer matters requires looking at what actually happened that got us here.
The Case That Forced the Question
Back in 2021, a researcher named Dr. Stephen Thaler built an AI system called DABUS and filed patent applications in multiple countries, including the United States, the United Kingdom, Germany, Japan, South Korea, and Australia, listing DABUS as the inventor. His argument was that the AI had independently come up with the ideas in those applications.
However, his applications were rejected on the same grounds that the inventor slot on a patent can only be filled by a human being.
The European Patent Office ruled that an inventor must be a natural person under its governing rules. In the United States, a federal appeals court ruled the same way, finding that the word “individual” in U.S. patent law refers to a human being.
What WIPO Did
In November 2025, WIPO held its 37th Standing Committee on the Law of Patents session in Geneva, where it presented an updated study tracking how countries around the world have handled the AI inventor question through their laws, court decisions, and patent office practices. The study pulled together responses from member states and regional patent offices, and it confirmed that the human-only rule is now the dominant standard globally.
Three weeks after the WIPO session, the USPTO released updated and replaced guidance replacing it had issued in February 2024. The new guidance removed uncertainty about how to handle inventions where both a human and an AI tool contributed. It confirmed that only humans can be named as inventors and that the standard for deciding who qualifies has not changed just because AI tools were used in the process.
What This Means for Anyone Using AI to Develop Products
Using AI in your research and development process is allowed. The rules are about who gets credited and not about whether AI can be used at all.
What the guidance now requires is that you’re able to explain, specifically and clearly, what you as the human contributed to each claimed part of the invention, and what the AI did as a tool in that process, such as generating draft outputs, suggesting options, or checking for errors.
Getting inventorship wrong can make a patent unenforceable or invalid entirely. Companies that use AI in their research pipelines should keep records showing how human inventors engaged with, modified, and directed the AI outputs used in each invention.
Why the Numbers Make This Urgent
WIPO data have shown that patent applications involving generative AI more than doubled between recently, with China filing more than 60% of all AI-related patents globally. This volume means that this is not a theoretical issue for a handful of researchers, as it affects companies across every industry that uses AI to build, test, and/or improve products.
This global position that AI is a tool that can only help you invent and cannot standalone as an inventor is now settled enough to act on. The practical question for any business filing patents today is to determine whether its internal processes clearly show that a human was in the driver’s seat throughout.
