PatentFig AI

PatentFig AI is a web-based tool that generates patent-compliant drawings from text descriptions, photos, sketches, or CAD screenshots. It produces line art, 3D renderings, flowcharts, and block diagrams formatted for USPTO, EPO, CNIPA, JPO, KIPO, and PCT filing. You describe your invention or upload a reference image, select the views you need, and get a ready-to-file figure set.

The tool takes a description or image and turns it into clean, labeled line drawings with reference numerals and leader lines following patent office conventions. You can generate multiple views (front, rear, top, perspective) that look consistent. A chat interface lets you modify figures using plain English — say "make the arrow thicker" and the AI updates the drawing. It supports version control (V1, V1.1, etc.) so you can track changes and revert. Export options include PDF, PNG, SVG, and TIFF at exact office specifications.

PatentFig AI is built for patent attorneys, agents, and inventors who need to produce figures quickly for filings. It speeds up early drafts, reduces manual redrawing, and helps standardize figure packages before sending to outside counsel. Real-world use cases include turning rough client photos into usable figure drafts, iterating on design patents with consistent multi-view sets, and converting CAD screenshots into clean line art for foreign office filings.
