Patent Drawing Software

Patent Drawing Software for Utility, Design, and Flowchart Figures

Generate patent figures from photos, sketches, screenshots, system descriptions, and method steps.

PatentFig AI is the end-to-end patent drawing software for IP attorneys, patent engineers, inventors, and in-house IP teams. Use one workspace for utility patent line art, design patent multi-view sets, patent block diagrams, software flowcharts, medical device figures, and filing-ready exports.

Trusted by patent teams filing in 6 major jurisdictions.

Everything you need to prepare patent drawings

One workspace for generation, refinement, compliance checking, and export.

AI Figure Generation

Turn product images, system descriptions, method claims, CAD views, screenshots, or rough sketches into clean black-and-white patent figures.

Utility and Block Diagram Workflows

Draft device structures, cross-sections, electrical system diagrams, software block diagrams, and AI/ML pipeline figures without starting from a blank canvas.

Chat-to-Modify

Refine any figure with natural language commands. Move components, adjust angles, or rename reference numerals without regenerating the entire drawing set.

Multi-View Consistency

Generate all six orthographic views (front, rear, left, right, top, bottom) from a single reference image, with guaranteed contour alignment across views.

Compliance Checker

Automatically check every figure for DPI, line weight, margins, color mode, and reference numeral legibility before you file.

Filing-Ready Export

Export to SVG, TIFF, PDF, or PNG with preset profiles for USPTO, EPO, CNIPA, JPO, KIPO, and PCT national-phase submissions.

Why IP teams switch to PatentFig AI

Compared to manual drafting or generic AI image tools, PatentFig AI cuts the time and cost of patent figure preparation.

Cut figure prep from days to minutes

Stop waiting days for external illustrators. Generate a complete, compliance-checked figure set in the same session you start it.

Avoid costly Office Actions

The built-in compliance checker catches 37 CFR 1.84 violations — margins, line weights, numeral legibility — before they become a Notice to File Corrected Application Papers.

Keep figures consistent across jurisdictions

Generate one conservative, portable figure set that works across USPTO, EPO, CNIPA, JPO, KIPO, and PCT with no per-office rework.

Iterate without losing prior work

Chat-driven surgical edits preserve the validated parts of your drawing set. No more full regeneration every time a claim changes.

Built for every major patent office

Office-specific drafting guidance is built in. Read the full rules for your jurisdiction:

Frequently Asked Questions

Common questions about patent drawing software.

What is patent drawing software?

Patent drawing software helps IP teams create, refine, check, and export compliant patent figures without relying on external illustrators. Modern tools like PatentFig AI use generative models to produce 37 CFR 1.84-compliant drawings from product images or descriptions, then provide built-in compliance checking and multi-format export.

Is AI-generated patent drawing software compliant with USPTO requirements?

Yes, if the software enforces the formatting rules in 37 CFR 1.84: black-and-white line art, specific margins, minimum line thickness, and legible reference characters. PatentFig AI bakes these rules into the generation process and runs a final compliance check before export.

How does PatentFig AI compare to generic AI image generators?

Generic AI image generators produce realistic renders that almost always fail patent formatting requirements. PatentFig AI enforces black-and-white line art, reference numeral discipline, multi-view consistency, and office-specific rules, then exports in filing-ready formats like SVG, TIFF, and PDF.

Can PatentFig AI generate design patent drawings with multiple views?

Yes. PatentFig AI generates all six required orthographic views (front, rear, left, right, top, bottom) plus a perspective view from a single reference image, with guaranteed contour alignment across every view.

Which export formats does PatentFig AI support?

PatentFig AI exports to SVG, TIFF, PDF, and PNG with preset profiles tuned to USPTO, EPO, CNIPA, JPO, KIPO, and PCT submission requirements. SVG is recommended for archival and iteration, while TIFF or PDF is preferred for final filing.

Do I need to be a patent attorney to use PatentFig AI?

No. PatentFig AI is used by patent attorneys, patent engineers, in-house IP teams, and independent inventors. The compliance guardrails mean you do not need deep knowledge of 37 CFR 1.84 to produce filing-ready figures.

How much does patent drawing software cost?

PatentFig AI offers a free trial with no credit card required. Paid plans scale with the number of figures and advanced features like multi-format export and team seats. See the pricing page for current plans.

Can I use PatentFig AI for both utility and design patents?

Yes. PatentFig AI supports utility patent figures (flowcharts, system diagrams, mechanical views, cross-sections) and design patent figures (multi-view orthographic sets with broken-line strategies and surface shading).
