Claude-Patent-Creator
An AI-assisted patent drafting and analysis system for Claude Code that combines (1) an MCP server exposing tools for MPEP/USC/CFR regulation search via hybrid RAG, (2) large-scale patent search via Google BigQuery (public patent datasets) plus optional USPTO API checks, (3) automated 35 USC 112(a)/(b) and formalities-style reviews, and (4) diagram generation using Graphviz.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Uses environment variables for API keys and suggests Google Cloud ADC for BigQuery. No explicit guidance is provided about MCP server auth, least-privilege scopes, or how secrets are redacted in logs. TLS expectations are not specified for MCP/any endpoints (likely local), and dependency hygiene/CVE status cannot be determined from provided content.
⚡ Reliability
Best When
You want an agent/tooling workflow inside Claude Code that can search regulations and patents, perform heuristic compliance checks, and generate draft artifacts/diagrams locally or with configured cloud APIs.
Avoid When
You require a turnkey hosted SaaS with clear SLAs, strict compliance controls, or minimal setup; or you need authoritative legal determinations rather than informational/assistive outputs.
Use Cases
- • Search relevant patent regulations (MPEP, 35 USC, 37 CFR, EPC, PCT) with citations
- • Conduct prior art searches across large patent corpora using keyword/CPC/IPC or full-text queries
- • Review drafted claims for 35 USC 112(b) style issues (e.g., definiteness, antecedent basis)
- • Review specifications for 35 USC 112(a) adequacy (e.g., written description/enablement)
- • Run formalities checks aligned to MPEP 608
- • Generate patent-style diagrams (block diagrams, flowcharts, architectures)
- • Guide an end-to-end patent application drafting workflow for USPTO/EPO
Not For
- • Providing legal advice or acting as a substitute for a licensed patent attorney/agent
- • Guaranteeing patentability/allowance outcomes
- • Use where you cannot comply with third-party API/data usage terms (BigQuery dataset, EPO OPS, USPTO API)
- • Production deployments requiring a stable, well-specified public REST API with strong operational guarantees
Interface
Authentication
Authentication is largely configuration-based via environment variables and Google Cloud ADC for BigQuery. MCP tools appear to be used by the local client (Claude Code) after setup; no user-facing auth model (API keys, JWT, scopes) is described for the MCP server itself.
Pricing
The repository itself is MIT licensed/open-source; external service costs depend on your cloud/API configuration.
Agent Metadata
Known Gotchas
- ⚠ BigQuery access requires correct Google Cloud setup and billing/quota in your project; misconfiguration can fail searches.
- ⚠ Large downloads/index builds (e.g., MPEP PDFs ~500MB) can be slow and GPU-dependent; repeated setup/builds may be expensive in time.
- ⚠ Diagram generation and retrieval tools may depend on local Graphviz availability.
- ⚠ EPO OPS full-text support requires separate EPO API credentials and may fail if not configured.
