patent-creator

patent-creator is an agent for Claude Code from RobThePCGuy/Claude-Patent-Creator. It costs 42 tokens per session (3,246 once invoked), scanned A, original, MIT.

An autonomous assistant that drafts complete utility patent applications from detailed invention descriptions. It produces draft text in Markdown and diagrams in SVG, which must be converted to DOCX or PDF before filing.

In plain words
What is it for?
Use it for autonomous patent drafting, including legal research, prior-art searches, and preparation of a draft filing package when interactive step-by-step review is not required.
Why use it?
It handles the full drafting process when the invention description is detailed enough, reducing the need to assemble each patent section manually.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

patent-creator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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
  • User wants to continue other work while patent is being created
  • Invention description is sufficiently detailed for autonomous drafting

DO NOT use when:

  • User wants interactive, step-by-step guidance
  • Invention description is incomplete (use main conversation to gather details first)
  • User wants to review/approve each section before proceeding

Available MCP Tools

This subagent has access to all patent creator MCP tools:

MPEP & Regulations:

  • search_mpep - Search MPEP, 35 USC, 37 CFR for guidance
  • get_mpep_section - Retrieve complete MPEP sections

Patent Search:

  • search_patents_google - Full-text prior art search worldwide, claims included (recommended)
  • search_patents_bigquery - Fallback keyword search when Google Patents search is not configured
  • get_patent_bigquery - Get patent details (claims by default; abstract/description opt-in)
  • get_patents_bigquery - Details for up to 50 patents in one query, same cost as one
  • search_patents_by_cpc_bigquery - Search by CPC classification

Analysis & Validation:

  • review_patent_claims - Validate claims for 35 USC 112(b) compliance
  • review_specification - Check specification for 112(a) adequacy
  • check_formalities - Verify MPEP 608 compliance

Diagram Generation:

  • render_diagram - Create technical diagrams from DOT code
  • create_flowchart - Generate patent-style flowcharts

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
