    2Check what already exists

    AI plans your search and shows real US patents that look closest, so you know where your claims need to be specific.

    • Specification
    • Claims
    • Abstract
    • Drawings
    • Application Data Sheet

    3Draft and prepare to file

    Generate the specification and claims from one invention model, see what's still missing, then work through each office's filing checklist.

    The rest of the filing, in the same project.

    Drawings, reviews, examiner responses, deadlines and the AI agent all work from the application you already built.

    Generate figures from a description in the style you choose, check each one is numbered and titled, and download them.

    Work with your applications and deadlines over a REST API, or connect an AI agent through the built-in MCP server. Keys are read-only unless you say otherwise.

    Questions, answered.

    No. Obsidyan is software that helps you prepare a patent application. It doesn't give legal advice or replace a qualified patent attorney or agent, so have one review your application before you file.

    Your idea deserves a filing date.
