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.

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.

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.”

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 — this 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.

“Effectively streamlines patent drafting for India by intelligently analyzing invention disclosures to generate drafts, figure descriptions, and claims.”
