Patent Lookup MCP Server

Look up patents BY NUMBER — get full details and citation chains for AI agents.

View on Apify | MCP Endpoint

---

What It Does

Give AI agents the ability to look up specific patents by number, retrieve full metadata and claims, and trace citation chains.

• Patent lookup by number — get full details for a specific patent
• Claims and metadata — abstracts, inventors, assignees, filing dates
• Citation tracking — forward and backward citation chains
• Google Patents — aggregated patent data with citations

---

Known Limitations

Keyword search is currently unavailable. The USPTO, EPO, and Google Patents search APIs are returning errors (404/503/403). To use this MCP, you must already know the patent number you want to look up.

Working features:

• get_patent_details — look up a specific patent by number
• find_patent_citations — trace citation chains for a known patent

Non-operational:

• search_patents — keyword search unavailable (APIs down)
• patent_landscape_by_company — company search unavailable (APIs down)

Quick Start

Add to your AI agent:

{
  "mcpServers": {
    "patent-search-mcp": {
      "url": "https://patent-search-mcp.apify.actor/mcp"
    }
  }
}

Or with authentication:

{
  "mcpServers": {

Tool parameters

get_patent_details

Parameter	Type	Required	Description
patent_number	string	Yes	Patent number (e.g., US10123456, EP3456789)
source	string	No	Source: uspto, epo, google, all (default: all)

When to call: Persona: IP lawyer or due diligence analyst. Scenario: Getting full metadata, claims, and assignee information for a specific patent being evaluated in a transaction.

Example AI prompt: "Get full details for patent US10712345 including the abstract, claims, and assignee information."

---

find_patent_citations

Parameter	Type	Required	Description
patent_number	string	Yes	Patent number to find citations for
citation_type	string	No	forward, backward, or both (default: both)

When to call: Persona: Patent strategist or innovation analyst. Scenario: Tracing citation chains to understand a patent's influence or find potentially infringing downstream patents.

Example AI prompt: "Find all forward citations for the original transformer patent US10967890 — show who has cited this patent."

---

search_patents

UNAVAILABLE — Keyword search is currently broken (USPTO/EPO/Google APIs returning errors).

Parameter	Type	Required	Description
query	string	Yes	Search query (keyword, CPC code, inventor name)
max_results	integer	No	Maximum results (default: 10)

When to call: Only when keyword search is restored. For now, use get_patent_details with a known patent number.

Example AI prompt: "Search for patents related to neural network attention mechanisms filed between 2020-2025, show 20 results."

---

patent_landscape_by_company

UNAVAILABLE — Company search is currently broken (APIs returning errors).

Parameter	Type	Required	Description
company_name	string	Yes	Company name to get patent landscape for
max_results	integer	No	Maximum patents to return (default: 50)

When to call: Only when company search is restored.

Connection examples

cURL

curl -X POST "https://patent-search-mcp.apify.actor/mcp" \
  -H "Authorization: Bearer YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"tool": "get_patent_details", "params": {"patent_number": "US10123456"}}'

Node.js

const response = await fetch('https://patent-search-mcp.apify.actor/mcp', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_APIFY_TOKEN',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    tool: 'get_patent_details',
    params: { patent_number: 'US10123456' }
  })
});
const data = await response.json();
console.log(data.result.title);

How It Works

Phase 1: Patent Lookup

• Accepts a specific patent number (e.g., US10123456)
• Fetches data from Google Patents HTML pages

Phase 2: Citation Tracing

• Parses the /cite page for forward and backward citations
• Returns structured citation chains

Phase 3: Aggregation

• Returns structured JSON with source attribution
• Includes direct URLs to patent records

---

Data Sources

Source	Coverage	Status
Google Patents	Aggregated	Working — HTML scraping for details/citations
USPTO	12M+ US patents	Search unavailable (API returning 404/503)
EPO	100M+ worldwide	Search unavailable (API returning 403)

Use Cases

Due Diligence

"What's in patent US10712345 — abstract, claims, assignee?" → AI calls get_patent_details with patent number → Returns full metadata

Citation Analysis

"Who has cited the original transformer patent US10967890?" → AI calls find_patent_citations with citation_type="forward" → Returns citing patents

Prior Art Research (when search is restored)

"Find patents from MIT researchers in the AI space" → AI would call search_patents with MIT inventor query → Returns MIT patent portfolio

Company Landscape (when search is restored)

"What's Apple's patent strategy in electric vehicles?" → AI would call patent_landscape_by_company → Returns filing trends, top patents
