Patentfig AI

Patentfig AI is an AI patent drawing software and patent figure generator for producing patent-compliant drawings.It generates line art, 3D renderings, cross-sections, flowcharts and block diagrams from sketches, photos or CAD screenshots using multi-modal input.

The workflow supports uploading references, describing the invention, selecting view angles, and producing office-ready figures with reference numerals and leader lines that follow USPTO, CNIPA, EPO, JPO, KIPO and PCT formatting.

Export options include PDF, PNG, SVG and TIFF formatted to patent office specifications, with batch export and multi-view set output.Editing features include natural-language “chat-to-modify” commands, version control with compare/revert, and slot-by-slot regeneration for iterative drafting.

Project management organizes figure sets, tracks versions and compliance status for inventors, patent agents, attorneys and IP operations teams.Security and data controls include encryption in transit and at rest, project deletion and retention controls, and contractual data processing options for business customers.

Use Cases

• Create office-ready patent figures from hand sketches, photos or CAD using Patentfig AI, generating patent-compliant line art, cross-sections and multi-view exports with automated reference numerals and leader lines for USPTO/EPO submissions
• Streamline patent prosecution and revision cycles by iteratively editing figures via Patentfig AI's chat-based editor, maintaining versioning and project controls while producing updated 3D renderings, annotated diagrams and examiner-ready visuals
• Batch-export complete sets of patent drawings—including 3D patent renderings, flowcharts and multi-view line art—with office-format numbering and export-ready layouts using Patentfig AI to share with counsel, drafters or global teams and eliminate manual redrawing and formatting
