PatentFig AI

PatentFig AI is an AI-native patent drawing platform that generates compliant figures (line art, 3D renderings, flowcharts) from text descriptions and reference images, ready for USPTO, CNIPA, EPO, JPO, KIPO, and PCT filing workflows.

What is PatentFig AI?

PatentFig AI is a web-based tool that converts text descriptions or uploaded reference images (photos, sketches, CAD screenshots) into patent-compliant drawings. It produces line art with reference numerals and leader lines, 3D renderings with multi-view options, and flowchart/block diagrams. The platform is developed by the PatentFig team and requires no local installation.

Key Features

• Patent Line Art Generation — Automatically generates clean, labeled line drawings from product photos or 3D models, adding reference numerals and leader lines following patent office conventions.
• Chat-to-Modify — Edit any figure using natural language commands (e.g., "make the arrow thicker" or "add a cross-section view") without restarting the generation process.
• Multi-Modal Input — Accepts reference photos, sketches, CAD screenshots, or plain text descriptions of inventions.
• Version Control — Every generation creates a new version (V1, V2...) with sub-versions for edits (V1.1, V1.2); users can compare and revert at any time.
• Professional Export — Exports in PDF, PNG, SVG, or TIFF at exact patent office specifications; batch export all views of a figure set with one click.
• Project Management — Organizes figures by patent application, tracking all figure sets, versions, and compliance status in one place.
• Multi-Office Support — Switches between USPTO, CNIPA, EPO, JPO, KIPO, and PCT/WIPO formatting workflows from a single set of source figures.
• Confidentiality — User prompts, uploads, and generated figures are never used for model training; encryption in transit and at rest; user-controlled retention with account deletion within 30 days.

Who is it for?

• Patent attorneys and agents — Quickly create reviewable first drafts for multi-view figure sets, then iterate via chat edits.
• Individual inventors — Turn rough sketches or product photos into filing-ready drawings without specialized illustration skills.
• IP law firms — Standardize figure packages for internal handoff and outside counsel, reducing back-and-forth.
• Corporate patent departments — Manage high-volume figure pipelines with project organization and version control across multiple applications.

What can you do with PatentFig AI?

• Generate line art from product photos — Upload a photo of a consumer electronics device and receive USPTO-compliant line art with reference numerals in minutes.
• Create flowchart diagrams from text — Describe a system logic in plain language (e.g., "data flow from sensor to processor to actuator") and receive a clean block diagram ready for filing.
• Produce multi-view design patent drawings — Select front, rear, top, bottom, left, right, and perspective views from a single 3D model input, ensuring consistency across all views.

How does PatentFig AI work?

1. Describe or upload a sketch: Enter a text description of the invention or upload a reference image (photo, sketch, CAD screenshot).
2. Choose view angles: Select the views and figure types (line art, 3D rendering, flowchart) you need.
3. Export and use: Download the generated figures in PDF, PNG, SVG, or TIFF at exact patent office specifications.

Pricing

PatentFig AI offers a freemium model with four tiers: Free (20 credits/month, ~2 figures), Basic ($20/month, 500 credits), Pro ($40/month, 1500 credits), and Enterprise ($80/month, 4000 credits). Yearly billing provides a 60% discount.

FAQ

What types of patent figures can PatentFig AI generate?

It generates patent line art (with reference numerals and leader lines), 3D renderings (multi-view), and flowchart/block diagrams. All output is formatted for patent office compliance.

Which patent offices are supported?

USPTO, CNIPA, EPO, JPO, KIPO, and PCT/WIPO workflows are available. Users can switch between office-specific formatting without regenerating source figures.

How does the credit system work?

Each generation or edit consumes credits. One figure typically costs around 10 credits. Free tier includes 20 credits/month; paid tiers scale up to 4000 credits/month.

Is my data secure?

User prompts, uploads, and generated figures are never used to train AI models. Customer content is encrypted in transit and at rest. Accounts can be deleted anytime, with removal within 30 days. DPA and NDA terms are available for business customers.

Can I edit the generated figures?

Yes, via the Chat-to-Modify feature. Users can issue natural language commands (e.g., "change line weight to 0.5mm") and the AI applies the change to the current version, creating a sub-version for tracking.
