PatentDrawVariations per task
Generate several takes on one description and compare layouts side by side before committing to a direction.
AI patent figure generator
Describe your invention. Get a working patent figure.
Write what the figure should show — components, connections, steps, labels — and PatentDraw drafts it as a structured technical figure. Improve the prompt, regenerate, and compare until the layout is right.

Inside the workspace
A drawing workspace tuned for technical iteration.
Everything in the workspace exists to shorten the distance between a written description and a figure you trust enough to review.
Prompt-driven refinement
Rewrite the description — tighter labels, a different view, clearer relationships — and regenerate only what changed.
Reference image guidance
Attach an existing sketch or figure so layout and visual context carry over into the generated draft.
High-resolution downloads
Finished drafts are stored in your workspace as downloadable materials at up to 2880px output.
How it works
Three steps from description to downloadable draft.
The workspace keeps the loop tight: write, generate, compare — and keep technical review in your hands.
Write the description
Name the parts, describe how they connect or run, state the view you want, and mention labels that must appear.
Set model, size, variations
Pick high or standard resolution, output shape, an optional reference image, and how many takes to generate.
Compare, refine, download
Weigh the variations against each other, sharpen the prompt where needed, and download the keeper from your workspace.
Common use cases
Choose the visual language that fits the invention.
Start with a clear description and let the figure type guide the layout.
System architecture
Block diagrams
Process flowcharts
Electrical concepts
Mechanical assemblies
Structural views
Method sequences
Component relationships
Prompt lab
The description is half the drawing.
Compare these weak and strong prompts — copy a strong one into your next task as a starting point.
“Draw a patent diagram of my weather station invention.”
“Block diagram of a weather station: outdoor sensor unit (102) sends radio data (110) to indoor console (104), which connects to a cloud server (106) through a Wi-Fi module (108). Show every connection path.”
Why it works: named parts, reference numerals, explicit connections, and a stated figure type.“Make a flowchart for my method.”
“Method flowchart with decision points: receive user input at S102; validate credentials at S104; if valid, load dashboard at S106; otherwise display error at S108; end at S110.”
Why it works: numbered steps in order, an explicit decision branch, and defined start and end.“Draw the parts of my handheld scanner.”
“Perspective view of handheld scanner (100) showing trigger (112), scan window (114), and battery compartment (116), with lead lines from each numeral to its part.”
Why it works: one stated view, numerals for every part, and lead-line instructions.Example outputs

Where AI drafting shines
- Invention disclosures and provisional filings that need clear figures fast
- First drafts you hand to an attorney instead of a blank page
- Block diagrams, flowcharts, and system views from written descriptions
- Exploring alternative views without paying for every revision
Where you still want a professional
- Certified formal artwork for complex filed applications
- Highly detailed drawings with strict office-specific conventions
- Figures where every dimension and tolerance must be exact
- Final review of any AI-assisted draft before submission
Credits and review
Predictable generation for focused work.
Each variation uses 10 credits. New accounts receive 10 free credits, so you can test the workflow before choosing a package.
Use your own technical context
Include the relationships, labels, and constraints that matter instead of relying on a generic image prompt.
Generate alternatives efficiently
Try different views or instructions and compare variations inside your workspace.
Keep human review in the loop
Check accuracy, terminology, numerals, margins, and filing requirements before using a result.
Download your finished work
Completed projects are available from your workspace as downloadable materials.
Important: PatentDraw creates working drafts, not legal advice or a guarantee of patent acceptance. Review all output with a qualified patent professional before filing.
