PatentFig
Patent Figures, Powered by AI
PatentFig is an AI-powered patent figure generation platform that turns text descriptions and reference images into patent-compliant technical drawings in minutes. Supporting USPTO, CNIPA, EPO, and JPO formatting standards, it eliminates the manual drafting bottleneck for inventors, attorneys, and patent firms.
Features
Patent Line Art Generation — Convert product photos or sketches into clean, labeled line drawings with reference numerals and leader lines following patent office conventions
3D Rendering & Multi-View — Generate front, side, top, and perspective views from a single reference input
Flowchart & Block Diagrams — Auto-create method/process flowcharts compliant with patent office requirements
Chat-to-Modify — Edit figures using natural language (e.g. "add a cross-section view", "make the arrow thicker")
Version Control — Every generation is versioned (V1, V1.1, V1.2…) with full history and revert support
Multi-Office Compliance — Switch between USPTO, CNIPA, EPO, and JPO formatting rules from one source file
Professional Export — PDF, PNG, SVG, TIFF at exact patent office resolution specs; batch export all views in one click
Project Management — Organize figure sets by patent application with compliance status tracking
Use Cases
Individual inventors preparing patent applications without expensive draftspersons
Patent attorneys and agents speeding up figure preparation for client filings
IP firms managing high-volume patent portfolios across multiple jurisdictions
Startups and R&D teams filing provisional patents quickly and affordably
Patent agents handling cross-border filings requiring USPTO + CNIPA dual compliance

I built PatentFig after noticing a frustrating gap in the patent filing process — the figures. Most patent tools focus on claims drafting or prior art search, but nobody had seriously tackled the illustration step. Patent drawings have strict formatting rules (line weight, reference numerals, multi-view requirements), and hiring a professional draftsperson costs hundreds of dollars per application and takes days. For independent inventors and early-stage startups, that's a real barrier. I started by asking: what if you could just upload a photo of your product or a rough sketch, describe what you need, and get a compliant patent figure in minutes? PatentFig is the answer to that question. It supports USPTO, CNIPA, EPO, and JPO standards, handles line art, 3D renderings, and flowcharts, and lets you iterate with natural language commands like "add a cross-section view" or "label part 3 as the housing." It's still early days — I'm a solo founder shipping fast — and I'd love to hear from anyone in the patent space: attorneys, inventors, IP professionals. What would make this indispensable for your workflow? Happy to answer any questions. Let's talk! 🚀
