Blunt preface: I do not recommend using AI to draft anything patent-related. It’s risky. But I know people will do it to save money, so here’s a careful, step-by-step playbook to minimize harm if you insist. I’m not endorsing this route, and human review still matters.

How to use ChatGPT to draft a provisional patent (safest-possible DIY version)

0) Before you type a word: protect yourself.

1) Gather the facts you’ll feed the model.

Make a “facts pack” you can paste in chunks: problem addressed, prior solutions, what’s new, components with labels, step-by-step operation, materials/options, manufacturing/assembly paths, performance targets, failure modes, and at least 3–5 design variations (“embodiments”). A prototype isn’t required, but your write-up must enable a skilled person to build it.

2) Use prompts that force structure and completeness.

Paste your facts, then run these in order:

Prompt A — Section skeleton
“Act as a technical scribe. Using only my facts (no outside info), draft:
Title; Field; Background (problems with prior art); Summary; Brief Description of Drawings;
Detailed Description with labeled parts and numbered steps; Embodiments/Variants; Advantages; Definitions.
Keep marketing out. Flag gaps with TODOs.”
Prompt B — Figures list
“Create a figure list (FIG. 1…N) with each view and the part numbers referenced.
Ensure consistent labels across text and figures.”
Prompt C — Embodiments expansion
“List at least 5 alternative embodiments that still achieve the core result.
For each, describe changes to parts, sequences, or materials.”
Prompt D — Enablement check
“Run an enablement audit: what can’t a skilled person build from this?
List missing dimensions, tolerances, interfaces, control logic, ranges, and manufacturing steps to add.”

3) Red-team the draft.

4) Drawings matter.

You can hand-sketch; just label parts to match the draft. Add block diagrams, flowcharts, and exploded views. The text must explicitly tie each figure to the description and part numbers.

5) Assemble the provisional package.

6) After filing: reality check.

“Patent pending” markets seriousness but gives no right to stop copycats. Use the 12 months to test, refine, and expand embodiments before you file the utility application. Filing too early with thin disclosure — or waiting too long — are both costly mistakes.

Safe-use tips for AI in this workflow

Bottom line

If you’re going DIY, structure your prompts to force completeness, obsess over embodiments, tie every figure to labeled parts, and file early enough to win “first-to-file” without sacrificing substance. Then use your 12 months wisely.
