What is PatentFig AI?

PatentFig AI creates patent illustrations from written descriptions and visual references, including photos, sketches, and CAD screenshots. It generates line drawings, 3D renderings, multiple views, flowcharts, and block diagrams for inventors, patent professionals, and drafting teams. Users describe or upload an invention, select views, and refine the resulting figures.

Figures can be revised through natural-language instructions, such as changing line thickness or adding a cross-section. Reference numerals and leader lines are editable separately from the drawing, with checks for duplicate numbers, empty labels, and crossing leaders. Each generation and edit is saved as a version, and projects keep related figure sets together.

Paid plans and credit packs include filing-sheet exports formatted for USPTO, EPO, PCT, CNIPA, JPO, and KIPO workflows, with office-specific margins, labels, sheet numbers, and a compliance report. Individual figures can also be downloaded as PNG, SVG, PDF, or TIFF. A recurring free credit allowance supports evaluation. Customer prompts, uploads, and generated figures are excluded from model training, including training by third-party AI providers.
