Use tool ↗About PatentFig AI
PatentFig AI produces the line-art figures, flowcharts, and block diagrams that patent filings require, formatted to match USPTO, EPO, and several other patent offices' drawing rules. You describe what the drawing needs to show, or upload a rough sketch or reference photo, and edit the result with follow-up natural-language instructions rather than a traditional drawing tool. Files export as PDF, PNG, SVG, or TIFF with version history kept per project. It's built for inventors and patent professionals preparing a filing rather than general technical illustration work.

Pros & cons of PatentFig AI
PatentFig AI solves a specific, filing-related problem: getting drawings into the exact format a patent office expects without hiring a draftsperson for every figure. It's worth using for straightforward mechanical or flowchart-style figures; anyone with genuinely complex or unusual drawings should still expect a human draftsperson to review the output before filing.
Pros
- Formats output for multiple patent offices, not just USPTO
- Accepts sketches or reference photos as a starting point, not just text
- Keeps version history per project instead of overwriting each edit
Cons
- Entry paid plan is priced monthly and isn't cheap for a single filing's worth of figures
- No indication of legal review or accuracy guarantee for filing-critical drawings
- The operator, TopLocalAI, LLC, is named in the footer, but the terms give no governing jurisdiction or address
Best for
- Independent inventors preparing their own provisional filing
- Patent attorneys who need quick draft figures before a professional draftsperson pass
- Teams filing across multiple patent offices with different drawing standards
Not for
- Complex mechanical drawings needing an experienced patent draftsperson's judgment
- One-off users who only need a single figure and don't want a monthly plan
Watch out: Treat the output as a drafting aid, not a substitute for review by a patent professional before submission; an incorrectly formatted figure can delay a filing.
