Can You Use AI to Draft a Provisional Patent Application?

What a US provisional is, and what it needs

A provisional application is a filing that secures a date for your invention without starting examination. According to the USPTO:

• It lasts 12 months and cannot be extended. If you miss the deadline, you may restore the benefit by petition within 14 months.
• It is not examined. No claim, oath or declaration and no information disclosure statement is required.
• The written description must still meet the requirements of 35 U.S.C. 112(a), and drawings are advised.
• A later non-provisional application can only claim the benefit of the provisional for what the provisional supports.
• It lets you say "patent pending" and starts the Paris Convention priority year.
• It is not available for design patents.

The filing fee is listed on the USPTO fee schedule as $325 for a large entity, $130 for a small entity and $65 for a micro entity, with no search or examination fee. Check the schedule on the day you file, as the USPTO revises it.

The point to take from that list is the third and fourth bullet. A provisional has no claims for an examiner to read, so the description is the whole asset. Whatever your later claims need must already be written down in it.

What AI is good at here

• Turning scattered notes into a structure. Technical field, problem, summary, detailed description, embodiments. A structured draft saves the first billable hours with an attorney. My article on writing a patent disclosure lists what the underlying material needs.
• Prompting you for missing detail. A good tool asks about alternatives, ranges and variants, which matter because an embodiment missing from the description generally cannot be added after filing.
• Producing a clean first draft quickly, which you then correct.
• Writing in a consistent format, including figure descriptions once you supply the figures.

Where AI drafts go wrong

1. The description does not support what you later want to claim. This is the one that matters most. A thin or generic description quietly limits how far your later claims can reach. A provisional that reads well but does not describe the specific mechanism, the ranges or the alternatives gives you a date for something narrower than your invention. See my guide to the patent specification for what a good description includes.

2. Invented content. General chatbots can cite prior art that does not exist or describe test results nobody measured. Anything in an application that you did not supply, and that is untrue, is your problem rather than the chatbot's. Invention Village's drafting page makes the same point: it lists the statements you must verify and the gaps left blank, and states that patent numbers can only come from the search results or from the material you gave it.

3. Confidentiality. What you type into a tool can leave your control. Before pasting anything about an unfiled invention, read the tool's terms for retention and training use. Invention Village states that your data is never used for AI training; whatever tool you use, get that statement in writing from the vendor. Also keep in mind that a description you enter into a tool is not protected by privilege the way a conversation with your own lawyer is.

4. Inventorship. Only natural persons can be inventors. The USPTO's revised guidance of 28 November 2025 rescinded its February 2024 approach and states that AI systems are tools used by human inventors, like laboratory equipment or software; the same standard of conception applies whether or not AI was used. In practice: the people who conceived the invention are the inventors, and the application must name them. If you used AI to generate the core idea, think carefully about whether any human actually conceived the claimed invention. My article Can AI Write a Patent? 2026 Legal Status goes through the DABUS cases and how the offices treat this.

5. Foreign filing rules. If your invention was completed in China, Article 19 of China's Patent Law requires you to obtain a confidentiality review from CNIPA before applying for a patent abroad. Under Article 8 of the Implementing Rules, that includes any filing in a foreign office, and the review is a separate step. If that applies, a US provisional filed first without that review may leave you in breach. Ask an attorney before you file.

6. Public disclosure. The USPTO says a pre-filing public disclosure may preclude foreign patenting, even though the US allows a 12-month window. If you plan to file abroad, do not show the invention in public first.

What the USPTO says about AI use in practice

In April 2024 the USPTO published guidance for practitioners and parties using AI tools. It states that AI use is not prohibited and creates no new duties. It reminds people that existing rules still apply: a person must sign the paper personally, certifying under 37 CFR 11.18(b) after reasonable inquiry that the statements are true and warranted; the duty of candor and good faith still applies; and practitioners must protect confidential client information (37 CFR 11.106). The USPTO's own webinar slides add that there is no obligation to disclose the use of specific tools to the USPTO unless the USPTO asks.

If you file without a lawyer, you are still the person certifying the paper. An AI-written statement you did not check is your statement.

A safe workflow

1. Write the invention down yourself first. Problem, solution, difference, effect. Include alternatives and ranges.
2. Use AI to structure and expand, not to invent. Mark anything it adds beyond your material.
3. Check every statement. Numbers, test results, references, names of materials.
4. Test the support. Write the claims you would want in the future, and for each element, point to the paragraph that supports it.
5. Add figures. Flowcharts, structure diagrams, anything that carries detail.
6. Check publication and foreign-filing issues (steps 5 and 6 above) before you file.
7. Have a qualified patent attorney or agent review. Especially if the invention is the basis of your company.
8. Diarize the 12 months. The date cannot be extended; plan the non-provisional or PCT filing before then.

Where Invention Village fits

If you want a structured first draft to take to your attorney, the Patent Drafting tool says that you describe your invention or upload your disclosure and get a complete draft application (specification, claims and abstract) in a few minutes, with prior art from a real search and a list of points only you can verify. It costs 50 credits per draft, with revisions to sections at no charge, and new users get 25 free credits. It states that a qualified patent attorney or agent still has to review the draft before you file, and that it does not file for you.

Two things the page does not say: it does not say the output is formatted specifically as a US provisional, and it does not say the result is ready to file. If you want a provisional, ask your attorney whether to trim the draft or keep the full specification, since a fuller description generally gives you more to rely on later.

If you are not sure that your idea is ready, first run the Patentability Assessment (1 credit per run; it checks whether the idea can be written up as a patent, and does not include a prior-art search) or read Is My Idea Patentable?. If you are not sure a patent is worth it at all, read When Not to File a Patent.
