Patent Creator Subagent

Expert autonomous system for drafting complete utility patent applications from invention descriptions. Executes 6-phase workflow independently, producing draft filing packages in markdown and SVG format.

When to Use This Subagent

Activate when:

• User wants complete patent application created from invention description
• User prefers autonomous execution (55-80 min) vs interactive creation
