The U.S. Patent and Trademark Office issued new guidance on November 26, 2025, providing crucial clarity on AI and intellectual property. The key ruling: inventions developed with AI assistance are eligible for patent protection, but only if a human qualifies as the inventor.
The Core Principle
The USPTO's position is clear: generative AI systems should be treated as tools, not inventors. Just as a computer-aided design system doesn't become an inventor by helping an engineer design a part, an AI system doesn't become an inventor by helping generate solutions.
What This Means in Practice
For companies using AI in R&D, the guidance provides a framework:
- AI-assisted brainstorming: Patentable if a human selects and refines the concepts
- AI-generated solutions: Patentable if a human provides significant creative input
- AI-only invention: Not patentable—no human inventor exists
Documentation Requirements
The guidance emphasizes that patent applicants must be able to demonstrate human contribution. This means companies should:
- Document the human's role in the inventive process
- Record prompts, iterations, and selection decisions
- Maintain logs of how AI outputs were refined
- Clearly identify which aspects came from human insight
The Broader Implications
This ruling has significant implications for AI-forward companies:
For R&D Teams: Continue using AI tools aggressively—they're legal and the outputs are protectable. Just ensure human inventors are genuinely contributing.
For Legal Teams: Update invention disclosure processes to capture AI involvement and human contribution.
For Strategy: Companies can't rely on AI alone to generate patentable IP. Human expertise remains essential for building defensible patent portfolios.
What Remains Unclear
The guidance doesn't resolve every question. How much human contribution is "significant"? What happens when AI contribution far outweighs human input? These boundaries will likely be defined through case law over the coming years.
For now, the message is: AI is a tool. Use it. But keep humans in the loop—literally, for legal reasons.
