Patent Fig
What is Patent Fig ?
AI patent drawing software designed for USPTO, CNIPA, EPO, JPO, KIPO, and PCT patent applications. Automatically generates compliant patent illustrations from text descriptions or uploaded sketches/photos, supporting line art, 3D multi-view renderings, flowcharts, and block diagrams. Smartly adds reference numbers and guide lines according to patent office standards. The Chat-to-Modify feature supports natural language refinements, with a version control system managing iterations and bulk export to PDF/PNG/SVG/TIFF formats, saving 90% of patent drawing time.

FAQ from Patent Fig
What types of patent illustrations can PatentFig AI generate?
Supports all types of patent illustration generation: 1) Patent line art - Automatically generates clean, numbered line drawings from product photos or 3D models, with AI adding reference numbers and guide lines; 2) 3D renderings and multi-views - Generates the full set of views required for design patents, including front view, back view, top view, and perspective view; 3) Flowcharts and block diagrams - Transforms system logic and algorithm processes into standard block diagrams. All outputs meet the patent office's requirements for line quality, numbering standards, and view proportions.
Which patent offices are supported?
Fully supports major patent offices worldwide: United States Patent and Trademark Office (USPTO), China National Intellectual Property Administration (CNIPA), European Patent Office (EPO), Japan Patent Office (JPO), Korea Intellectual Property Office (KIPO), and PCT/WIPO international applications. You can switch format standards between different offices with one click, automatically generating compliant versions of the same source images for multiple offices without needing to redraw.
How does the point system work?
A point-based payment system based on generation volume: The Free version provides 20 points per month (suitable for trial), the Basic version at $20/month includes 500 points (about 100 images), the Pro version at $40/month includes 1500 points (firm-level), and the Enterprise version at $80/month includes 4000 points (enterprise-level). Each generated image or modification consumes 1 point, with a 60% discount for annual payment. Points reset each month and do not accumulate, fitting the cyclical demand characteristics of patent applications.
Can the generated illustrations be edited?
Yes, you can use the Chat-to-Modify conversational editing feature, where precise modifications can be made using natural language commands. For example, you can say 'thicken the lines', 'add a cross-section view', or 'adjust the arrow direction', and the AI will apply the changes immediately. Each edit generates a new version (V1.1, V1.2), maintaining a complete version history for easy comparison and rollback, avoiding the hassle of starting from scratch in traditional drawing software.
Is the data safe?
Absolutely secure. The platform uses enterprise-level encryption storage, and all uploaded invention sketches, technical descriptions, and generated diagrams are solely for your patent applications and will not be used for model training or external display. Supports project-level permission management, allowing different team members to have varying access levels. It meets the security standards for enterprise IP management, ensuring complete confidentiality before disclosure of inventions.
How to create patent illustrations that meet USPTO requirements?
After selecting the USPTO mode, the system automatically applies the format standards of the United States Patent and Trademark Office: 1) Line thickness compliant with 37 CFR 1.84 standards; 2) Reference number format standards; 3) Page margins and paper sizes in compliance; 4) Contrast optimization for black and white line drawings. Once generated, you can directly export to PDF or TIFF format, ready for submission without post-adjustments. It also supports generating shadow lines and surface texture representations required for design patents.
Can PatentFig AI replace Visio or AutoCAD?
Not exactly a replacement, but rather an acceleration layer for patent drawing processes. For specific types of illustrations required for patent applications (line art, multi-view, flowcharts), PatentFig AI can be 10 times faster than general CAD software while automatically conforming to patent office standards. However, for complex mechanical assembly drawings or engineering drawings requiring precise dimension markings, it is advisable to complete them in traditional CAD before importing for optimization. The best practice is to quickly generate drafts and iterations with PatentFig AI, which are then reviewed by professional draftsmen.
Can design patent illustrations with multiple views be generated?
Absolutely. After uploading product photos or sketches, you can generate the six orthographic views (front, back, left, right, top, bottom) and a perspective view required for design patents with one click. The AI ensures consistency in proportion and feature correspondence between views, automatically adding necessary break lines and section lines. It supports automatic addition of shadow lines required for US design patents, ensuring a one-time pass through USPTO's formal examination.
Alternative of Patent Fig
AI scientific illustration and data visualization platform, specifically designed for researchers.
