What Happened
Stephen Thaler tried to patent inventions created by his AI system, DABUS. He listed the AI as the inventor. The courts said no—only humans can be inventors under current law.
Why It Matters
AI is getting better at generating novel solutions—designing drugs, creating circuits, writing code. If AI produces something genuinely new, who owns it? The courts say if no human contributed to the conception, there's no patent. The invention belongs to nobody, or maybe it's protectable only as a trade secret.
But AI-assisted invention is still patentable. If a human uses AI as a tool—defining the problem, selecting training data, evaluating outputs, recognizing the inventive concept—that human is the inventor. The AI is just a sophisticated calculator.
This distinction matters for companies developing AI systems. You can't just let AI run and patent whatever comes out. You need humans meaningfully involved in the inventive process.
What You Should Know
If you're using AI in R&D, document human contributions carefully. Show how humans defined problems, selected data, evaluated results, and recognized inventions. That documentation supports inventorship.
Don't try to list AI as an inventor—it will be rejected. Instead, identify the human contributors and claim their contributions.
For purely AI-generated innovations, consider trade secret protection. If the innovation can't be reverse-engineered and you can keep it secret, that might be better than patent anyway.
The law may evolve as AI capabilities grow. But for now, human inventors are required.
