Patent Diagram Generator

Generates patent-style technical diagrams using Graphviz, handling flowcharts for method claims and block diagrams for system claims with proper USPTO-style reference numbering (10, 20, 30, etc.). You feed it step definitions or component blocks and it spits out SVG, PNG, or PDF files. The nice bit is the automatic reference numbering and built-in patent formatting conventions, so you're not manually labeling everything. Supports multiple layout engines (dot, neato, circo) and includes templates for common patterns. Requires Graphviz installed locally, but once that's set up it's straightforward Python calls. Most useful if you're actually filing patents and need those clean technical figures, less so if you just want quick informal diagrams.

Patent Diagram Generator Skill

Windows PowerShell: replace a macOS/Linux Python invocation with & "$HOME\patent-creator-venv\Scripts\python.exe" and a CLI invocation with & "$HOME\patent-creator-venv\Scripts\patent-creator.exe". Keep script paths quoted. Python code blocks are Python source, not shell commands.

Create patent-style technical diagrams including flowcharts, block diagrams, and system architectures using Graphviz.

When to Use

Invoke this skill when users ask to:

Create flowcharts for method claims
Generate block diagrams for system claims
Draw system architecture diagrams
Create technical illustrations for patents
Add reference numbers to diagrams
Generate patent figures
