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.
Produce utility patent line art, design patent multi-view sets, and process flowcharts with consistent reference numerals from photos, sketches, 3D references, or short prompts.
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
Real outputs from the patent figure generator
Same workflows as your filings: utility, design, and CNIPA cross-jurisdiction cleanup.
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
Most teams start from one of three inputs: a product photo, a rough sketch, or a 3D model screenshot.
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.
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.
