PatentFig AI Figures Generator for n8n Workflow Automation

Turn an invention description into a patent-style figure—automatically inside n8n

The PatentFig AI Figures Generator for n8n Workflow Automation is a ready-to-run n8n workflow that sends your invention description to PatentFig AI, generates a labeled patent-style PNG or SVG figure, and downloads the resulting image back into n8n as binary data for the next step in your process.

What this workflow does

• Manually executes when you run the workflow in n8n (Manual Trigger).
• Sets your invention description, chooses the output format (PNG or SVG), applies your labeling preference (labeled true/false), and creates an idempotency key based on the execution ID.
• Sends a POST request to the PatentFig AI Figures API at https://patentfig.ai/api/v1/figures using HTTP Header Auth (Authorization: Bearer <your_key>).
• Reads the returned file URL from PatentFig AI and downloads the generated figure into n8n as binary output.

Use cases

• Generate patent-style visuals for invention documentation, investor materials, or internal reviews.
• Create labeled figures to speed up prototype-to-patent drafting workflows.
• Automate figure creation for SaaS teams running n8n automation and storing outputs in downstream systems.

Technical details

• n8n nodes used: Set, Sticky Note, HTTP Request, Manual Trigger.
• Authentication: HTTP Header Auth credential with Authorization: Bearer <your_key>.
• API integration: POST to https://patentfig.ai/api/v1/figures, then download the resulting image file URL as binary.

Requirements

You’ll need an n8n instance, a PatentFig AI account with an API key, and at least 10 credits per generated figure. The workflow template itself is free.
