PatentFig AI

Patent attorneys, agents, and IP teams currently mark up screenshots and redraw invention figures manually, a slow process especially for multi-view figure sets. Rough client materials like photos are often deemed unusable, halting progress until cleaner drawings can be produced through a separate drafting cycle. Small edit requests, like adjusting a line weight or adding a sectional view, traditionally require restarting the drafting process. Coordinating figure versions across inventors, counsel, and operations, and standardizing packages before they go to outside counsel, creates avoidable back-and-forth. Filing across multiple patent offices (USPTO, CNIPA, EPO, JPO, KIPO, PCT) adds further formatting complexity.

PatentFig AI generates patent-compliant figures, including line art, 3D renderings, and flowcharts/block diagrams, from text descriptions, sketches, CAD screenshots, or reference photos in a three-step workflow: describe or upload, choose view angles, and export. AI automatically adds reference numerals and leader lines following patent office conventions. A chat-to-modify feature lets users edit figures with natural language commands like 'make the arrow thicker,' applying changes instantly. The platform tracks version history (V1, V2, with sub-versions like V1.1), supports professional export formats (PDF, PNG, SVG, TIFF) with batch export, organizes figures by project, and supports formatting workflows for USPTO, EPO, CNIPA, JPO, KIPO, and PCT/WIPO from one set of source figures.
