Patent Figure Generator

Patent Figure Generator — Generate USPTO Patent Drawings Online

Turn product photos, hand sketches, or short prompts into filing-ready patent figures. Free tier, no credit card.

Built for searches like "patent figure generator", "patent figures generator", "create patent figures", and "ai patent figure". Produce utility patent line art, design patent multi-view sets, and process flowcharts with consistent reference numerals — all in your browser.

Photo, sketch, 3D screenshot, or short text prompt as input

Utility patent figures, design patent multi-view sets, and flowcharts

Consistent reference numerals carried across every figure in the set

Built-in USPTO / CNIPA / EPO / JPO / KIPO compliance checking

What a real patent figure generator should do

Generic image tools draw "a patent-looking diagram." A patent figure generator has to handle the constraints that get applications rejected.

Hold reference numerals consistent
Element 12 in FIG. 1 must still be element 12 in FIG. 5. PatentFig tracks numerals across the whole set, not per image.
Apply the right line discipline
Uniform line weight, no fragmented strokes, broken lines exactly where claim scope requires them — generic AI tools cannot enforce this.
Export at filing DPI
Direct 300 / 600 DPI export so the same figure works for online filing portals and reproduction in published patents.

Three workflows users hit most often

These match the highest-converting search intents we see: photo→figure, sketch→figure, and 3D-model→figure.

Photo → patent figure
Upload a product photo. The generator extracts contours, cleans glare and background, and proposes a labeled patent-style line drawing.
Sketch → patent figure
Hand-drawn napkin sketches and tablet whiteboards become consistent line art with proper margins and reference numerals.
3D model → multi-view set
For design patents, generate the full set of orthographic views (front, rear, left, right, top, bottom) plus a perspective view from a single 3D screenshot.

Real outputs from the patent figure generator

Same workflows as your filings: utility, design, and CNIPA cross-jurisdiction cleanup.

Utility patent line drawing with USPTO-compliant margins
Sketch → utility patent figure with USPTO-compliant margins.
Design patent multi-view set with broken lines and shading
Photo → design patent multi-view set with broken lines and shading.
Cross-jurisdiction CNIPA-clean line work
Cleanup pass for CNIPA cross-jurisdiction filing.

Patent Figure Generator FAQ

What is a patent figure generator?
A patent figure generator is a tool that produces filing-ready patent drawings — utility line art, design patent multi-view sets, and flowcharts — from photos, sketches, 3D models, or text descriptions, with patent-specific constraints like uniform line weight and consistent reference numerals built in.
Is there a free patent figure generator?
PatentFig has a free tier you can use without a credit card. Paid plans start at $50/month (Basic) for higher-volume use, $100/month (Pro), and $1,999 lifetime.
Can I generate patent figures from a photo?
Yes. Upload a product photo and the generator extracts the silhouette, applies patent-style line work, and proposes reference numerals. This is one of the most common workflows users run.
Will the generated figures pass USPTO formal review?
The generator produces output that targets 37 CFR §1.84 (margin, line, numeral, view requirements). The built-in Figure Checker validates each figure before you file, catching issues that would otherwise trigger a Notice to File Corrected Application Papers.
How is this different from drawing in Visio, Illustrator, or CorelDRAW?
Visio, Illustrator, and CorelDRAW are general drawing tools. PatentFig is purpose-built for patent figures: numeral tracking across figures, broken-line conventions for design patents, multi-jurisdiction compliance checks, and 300/600 DPI filing export.
Does PatentFig work for design patent drawings too?
Yes. From a single product photo or 3D screenshot, the generator produces the full set of required views — front, rear, left side, right side, top, bottom, and a perspective view — with broken-line conventions for unclaimed environment.
