One workspace, from first notes to a file you can send

A disclosure, a search report, claims and a complete specification come to 25 credits. The 7-day trial includes 300.

  1. Step 1

    Disclosure

    Upload a PDF or Word file and let autofill structure it, or answer the guided invention disclosure questions yourself.

    10 credits to autofill

  2. Step 2

    Search

    An AI agent searches USPTO, EPO and IP India records. Pick the closest hits and get an editable patentability report.

    3 credits per report

  3. Step 3

    Draft

    Claims come first. The complete specification and abstract are then written around them, in the office format you chose.

    6 credits each for claims and specification

  4. Step 4

    Claims review

    Edit the claims in the editor, or ask the copilot to narrow, broaden or reword one, before you generate the specification.

    5 credits per copilot message

  5. Step 5

    Export

    Download .docx or PDF, then have a registered patent attorney or agent check it before it is filed.

    No credits

Need figures too? Build a figure plan with reference numerals and render patent drawings (Beta) in the same workspace.

Watch a sample invention go from disclosure to specification

A wireless charging invention, step by step: autofilled disclosure, annotated figures, claims with the copilot, then the specification and export.

AI Drafting Platform

Not just faster drafts. Better ones.

Paste your invention disclosure. The AI writes the claims first, then builds the specification around them, the way experienced patent attorneys and agents draft. See how our AI patent drafting software works, or try it free for 7 days.

Start Free Trial
AI Prior Art Search

Describe your invention. Get a search report.

Enter your invention description and select patent offices. An AI agent searches the USPTO, EPO and IP India in parallel. You pick the relevant patents, and it writes a structured prior art report you can edit and export as .docx.

Mid-draft assistance

Stuck on a claim? Ask the AI copilot.

Select any claim or section. The copilot sees your full invention context and responds inline. Broaden scope, restructure dependents, or refine language.

Claims-first drafting

Complete specifications, ready for review

Provisional drafts and complete applications: claims, description, abstract and brief description of the drawings, in the section structure of the office you file at. DPMA drafts come out in German.

End-to-end workflow

From Disclosure to Draft

Generate claims from your disclosure, build the complete specification around them, and export the application as .docx, laid out for the USPTO, EPO, DPMA or IP India.

Why not just use ChatGPT?

ChatGPT is a capable general assistant, and for explaining a technology or rewording a paragraph it is often enough. A patent application needs a fixed structure, claims the description supports, and an unfiled invention kept out of training data.

Office format
General AI chat: You describe the USPTO or EPO structure in your prompt, then check the headings, claim numbering and sections yourself.
PatentAssist: USPTO, EPO, DPMA (in German) and IP India formats are built in. Pick the office when you create the draft.
Claim support
General AI chat: Claims and description are written in whatever order you ask, often across a long chat. You check that each claim is supported.
PatentAssist: Claims are drafted first, then the specification, abstract and figure descriptions are written around them, from one disclosure.
Prior art
General AI chat: Searches the web with cited sources. Useful background, but it is not a patent database.
PatentAssist: AI agentic search and patentability reports over USPTO, EPO and IP India records, in the same workspace as the draft.
Confidentiality
General AI chat: On Free, Plus and Pro, chats can be used to train OpenAI's models unless you turn that setting off. Business and Enterprise plans don't train by default.
PatentAssist: Never trains on your content. AI runs on Azure OpenAI in the EU, and a GDPR Article 28 DPA covers every account.
Figures
General AI chat: Generates images, but not to patent drawing conventions.
PatentAssist: Figure plans with reference numerals and rendered patent drawings (Beta), plus the brief description of the drawings.

ChatGPT plan terms as checked on 26 October 2026. Whichever tool you use, the attorney or agent who signs the filing still checks the draft. Read the full PatentAssist vs ChatGPT comparison or our honest answer to can AI write a patent application.

Data Protection Active

Your inventions are trade secrets. We engineered it that way.

Until it is filed, an invention disclosure is confidential, and a leaked draft can cost you novelty. Every account is covered by an Article 28 GDPR data processing agreement, and we publish every sub-processor we use.

What we are not: PatentAssist itself holds no SOC 2 or ISO 27001 certification. Our infrastructure providers, Microsoft Azure and Amazon Web Services, hold those for the layer they run.

AES-256 Encryption

Databases, backups and uploads are encrypted at rest, and every connection uses TLS 1.2 or later. Encryption is always on.

Zero AI Training on Your Data

Your invention disclosures and drafts never train any AI model. Azure OpenAI's enterprise terms rule it out, and we don't train on them either.

EU AI Processing

The AI models that draft and search run on Azure OpenAI in Sweden Central and Italy North. The app and its database are hosted in Azure Central India, and the patent index on AWS in Mumbai.

Patent agents draft faster with PatentAssist

Here's what practitioners say after drafting their first specification.

“The autofill function is particularly impressive. It allows users with limited information to create comprehensive provisional specifications efficiently.”
Read full review

I recently discovered PatentAssist.ai while conducting an online search for patent drafting tools. My experience with the platform has been quite positive, showcasing several strengths that make it a valuable resource for patent practitioners.

One notable strength is the platform's ability to generate a solid first draft. The autofill function is particularly impressive; it allows users with limited information to create comprehensive provisional specifications efficiently. Additionally, the tool is capable of producing a decent independent claim that is not tied to any specific system, which enhances its versatility.

Despite some challenges, I believe PatentAssist.ai offers valuable features that can significantly aid in the patent drafting process. Overall, it is a commendable tool for those navigating the complexities of patent applications.

“Even without edits, the output is 60-70% complete, cutting down the time and effort needed to finalize a patent application.”

AI in patent drafting is evolving fast, and I recently had the chance to try PatentAssist.ai for drafting. Getting started was easy, and the platform feels intuitive right from the beginning.

One of the standout features is the auto-fill for IDF, which saves time by pulling in details automatically. For full specification drafting, I like that it starts with claim generation first, allowing users to refine them before moving forward, which is a thoughtful approach. When it comes to provisional applications, the tool is among the best I've seen.

The Co-pilot feature lets you ask questions and make modifications on the go. It's a real time-saver. You can either edit directly on the platform or download an editable document, already formatted as per Indian Patent Office requirements. Security also seems robust, and the pricing is competitive.

All in all, PatentAssist.ai is a solid starting point for patent drafting. Even without edits, the output is 60-70% complete. For professionals, this means higher efficiency and productivity.
