Installation

pip install patent-intelligence-mcp-server

Quick Start

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "patents": {
      "command": "patent-server"
    }
  }
}

Claude Code CLI

claude mcp add patents -- patent-server

Direct Usage

patent-server

Example Queries

Once connected, your AI agent can answer questions like:

Basic Search:

• "Search for recent patents about quantum computing"
• "Show me details for patent US-11234567"
• "What patents has Elon Musk filed?"
• "Find all Tesla patents"

Advanced Analysis:

• "Compare Apple's and Samsung's patent portfolios over 5 years"
• "Show me the technology landscape for solid state batteries"
• "Find patents in CPC class G06N (machine learning)"
• "Show the newest patents about mRNA vaccines from the last 6 months"
• "Analyze patent trends in CRISPR technology over 10 years"
• "How does Google's patent portfolio compare to Microsoft's?"

New in v0.3.0:

• "Search patents in IPC classification H04L9/32 (cryptographic authentication)"
• "Find the patent family for patent 11234567"
• "Who are the top patent holders in the pharma sector?"
• "Give me a strategic landscape analysis for quantum computing"
• "Extract the claims for patent 11234567"
• "Show me recent AI patents from the last 30 days"

CPC Classification Codes

Common codes for the search_by_cpc tool:

Code	Area
G06N	Machine Learning / AI
G06F	Digital Data Processing
H01L	Semiconductor Devices
H04	Telecommunications
A61K	Pharmaceuticals
C12N	Biotechnology
B60	Vehicles
F03D	Wind Turbines

API Source

USPTO PatentsView API — Free, no API key required. Covers all US patents with full metadata, inventors, assignees, citations, and CPC classifications.

Configuration

Optional environment variables:

Variable	Default	Description
PATENT_HTTP_TIMEOUT	30	HTTP request timeout in seconds
PATENT_DEFAULT_LIMIT	10	Default number of results
PATENT_MAX_LIMIT	50	Maximum results per query
PATENT_CACHE_ENABLED	true	Enable/disable response caching
PATENT_CACHE_TTL	600	Cache time-to-live in seconds

Performance

• Parallel requests: Patent details fetch 4 data sources simultaneously instead of sequentially
• Trend analysis: Year-by-year queries run in parallel (5-year analysis: ~1 request time instead of ~5)
• Landscape analysis: 5 parallel API calls for comprehensive results in a single request cycle
• In-memory caching: Repeated queries return from cache (256 entries, 10-minute TTL)
• Patent families: Parallel citation + base patent lookups
