For two centuries, inventorship was a formality. You signed a declaration. The patent issued. Nobody looked back.
That era is over. Generative AI, distributed co-invention, and increasingly complex chains of title have transformed a once-routine question into a potential litigation event: who, and what, actually invented this?
Key Takeaways
- AI-assisted invention requires a defensible record of meaningful human contribution to patent claims.
- Distributed teams, contractors, consultants, and collaborators can create significant inventorship and ownership risk.
- Weak assignment language and incomplete chain-of-title records often surface at the worst possible time.
- Contemporaneous provenance records can strengthen diligence, financing, acquisition, and enforcement positions.
Three forces converged to end it: generative AI in the invention process, distributed co-invention across contractors and collaborators, and an ownership-dispute docket that keeps growing because chain of title keeps failing. Each one turns the same question into a litigation event: who — and what — actually invented this?
The law did not move. Your workflow did.
Start with the statute. 35 U.S.C. § 100(f) defines an inventor as an “individual.” The Federal Circuit confirmed in Thaler v. Vidal (2022) that an AI system cannot be a named inventor. The Supreme Court declined to hear it. That question is closed.
What is not closed is the harder question: when a human uses AI to invent, which human contribution counts? The USPTO answered in its February 2024 guidance on AI-assisted inventions. AI-assisted inventions are patentable — but only where a natural person made a significant contribution to each claim, measured under the Pannu factors. Recognizing a problem is not enough. Reducing an AI's output to practice is not enough. Prompting, selecting, and materially shaping the claimed invention can be enough.
Notice what this guidance quietly demands: a claim-by-claim record of who contributed what, and how. Almost no R&D organization keeps one.
Every Engineer With a Chatbot Is a Provenance Problem
Your scientists are using generative AI today, whether your policy acknowledges it or not. When a claim element originates in a model's output and no human made a significant contribution to it, that claim is vulnerable. When your inventors sign the § 115 declaration anyway, you have compounded a validity problem with a candor problem — and inequitable conduct kills entire patents, not single claims.
Which tools, which prompts, which outputs, which human decisions transformed output into invention. Provenance is not a compliance tax. It is what makes AI-assisted invention patentable at all.
Co-Inventors: The Cheapest License Your Competitor Will Ever Get
Joint inventorship is brutally generous. Under Ethicon v. U.S. Surgical (Fed. Cir. 1998), a person who contributed to a single claim is a co-inventor of the patent — and absent an agreement, a co-owner who can license the whole patent to anyone, including your competitor, without your consent and without sharing a dollar.
Modern invention is distributed. Contract engineers. University collaborators. Consultants on Slack. A CRO's scientist who suggested the modification that became claim 7. If your records cannot establish who contributed each element, you cannot keep improper inventors off the patent — and you cannot keep proper ones on it.
Both errors are exploitable. Derivation proceedings under AIA § 135 and inventorship-correction fights under § 256 are provenance contests. The better record wins.
Ownership Disputes Are Lost in the Hiring Paperwork
Stanford v. Roche (2011) turned on verb tense. “Agree to assign” lost to “do hereby assign.” Stanford — with the federal government behind it — lost rights in HIV diagnostic patents because of the wording of an assignment signed years earlier.
Every diligence review I run finds the same defects: employment agreements with promissory assignment language, consultants with no IP terms at all, founders who invented before incorporation and never assigned, AI vendors whose terms of service claim rights in outputs.
During financing, acquisition, or enforcement, the record is fixed and the leverage belongs to the other side.
Provenance Is Now a Diligence Question With a Price Attached
Acquirers and underwriters have learned to ask: show me the origin of each material asset. Who invented it, under what agreement, with what tools, assigned through what chain.
Companies that can answer close faster and keep their valuation. Companies that cannot answer fund the discount, the escrow, or the walked deal.
What a Defensible Provenance Record Looks Like
The discipline is not complicated. It is merely unforgiving of retrofitting.
- Contemporaneous invention records that tie each claim element to a named human contributor.
- AI-use logs preserved alongside lab notebooks and design history.
- Present-tense assignment language executed on day one of every employment and consulting relationship, audited annually, not at exit.
- Claim-level inventorship analysis before filing, not after a dispute.
- A provenance audit before any financing or transaction, run by your side, on your timeline.
The record you build today is the case you win later. The record you skip is the case you settle.
Build the Record Before Someone Else Tests It
That's the audit we run at PatentVest, claim-level, before a financing, acquisition, or enforcement action, on your timeline, not the other side's.
If it raises questions about your own portfolio, you can always contact the PatentVest team.
