Agentic AI is generating patentable inventions faster than any examination system was built to handle. Human inventorship is now settled in most major jurisdictions. But how much human contribution is “enough,” and how to document it, remain unsettled in highly autonomous workflows.

PYMNTS published a timely piece this week on where the global patent system stands.

The numbers show increasing pressure: Per WIPO’s World Intellectual Property Indicators 2025, innovators filed a record 3.7M patent applications worldwide in 2024 — up 4.9%, the fastest growth since 2018 — with AI and computing as key drivers. The five largest offices (EPO, JPO, KIPO, CNIPA, USPTO), handling ~85% of filings, are revisiting their joint AI roadmap amid the surge.

Global Consensus on Human Inventorship

Major jurisdictions uniformly require at least one natural person as inventor; AI cannot be named. The USPTO’s November 2025 Revised Inventorship Guidance reaffirms this — AI is a tool, only humans “conceive” under 35 U.S.C. § 100(f). Europe (EPO), China, Japan, Korea, and the UK align: AI-assisted inventions are patentable with sufficient human input; purely autonomous AI output is not.

Where It Gets Uncertain

The doctrine was built for human-led invention. Agentic systems that autonomously search vast solution spaces strain the “conception” standard — which requires a definite, permanent idea formed in a human mind. As the Journal of Intellectual Property Law & Practice notes, frameworks have advanced, but fact-specific questions persist over what counts as sufficient human contribution in autonomous workflows. The practical risk: inconsistent outcomes across examination, the PTAB, and litigation.

U.S. Alignment

There’s no real divide between agency and courts. The USPTO guidance tracks Federal Circuit precedent (e.g., Thaler v. Vidal and established conception doctrine), treating AI as a tool under uniform standards. Courts still own the binding interpretation, and the guidance adds examination clarity. Inconsistent standards across jurisdictions can also put priority and foreign validity at risk.

What It Means for R&D Teams

Document the human contribution rigorously, including problem framing, hypothesis selection, evaluation of AI outputs, and iterative refinement. Well-documented portfolios are more likely to survive scrutiny. Applicants that skip this discipline invite rejections and invalidity challenges as agentic AI scales.

Jurisdictions will continue to diverge on how much and what kind of human input inventorship requires. As AI becomes more than “just a tool,” traditional concepts of inventorship will be tested.
