What the publisher says

From the Patent Search repository's README, as published. We do not edit it. Read it on GitHub

patent-search-mcp-server

MCP (Model Context Protocol) server for the AI Patent Search Generator — patent dossiers, prosecution history, Office Action AI analysis, citation/family/CPC lookups, plus a legal-intelligence layer (PTAB validity challenges, district-court litigation, company-litigation lookup, legal status, chain of title, term) and a one-shot AI risk profile. All from USPTO public data. Works in Claude Code, Claude Desktop, Cursor, ChatGPT-with-MCP, and any other MCP-compatible client.

26 tools available.

  • Patent data: dossier, claims, claimchart, prosecution, prosecutiontimeline, oaanalyze, examiner, attorney, entitystatus, term, assignments, legalstatus, pregrantpub, query, search, similar, citations, family, cpc, cpc_suggest, balance.
  • Legal intelligence (new): challenges (PTAB validity challenges — who attacked the patent and did it survive), litigation (US district-court infringement suits — who sued whom), company_litigation (reverse lookup: all patent suits involving a company).

Prerequisites

  1. Install the AI Patent Search Generator Chrome extension and sign in.
  2. Generate an API key from the extension's Admin tab.
  3. Node.js 18+ (only required for local installs; npx-style configs don't need a local install).

Configure in Claude Code

Add to your MCP config (~/.claude/mcp.json or project-scoped .mcp.json):

{
  "mcpServers": {
    "patent-search": {
      "command": "npx",
      "args": ["-y", "patent-search-mcp-server"],
      "env": {
        "PATENT_SEARCH_API_KEY": "psg_live_..."
      }
    }
  }
}

Configure in Claude Desktop

Edit ~/Library/Application Support/Claude/claudedesktopconfig.json (macOS) or %APPDATA%\Claude\claudedesktopconfig.json (Windows):

{
  "mcpServers": {
    "patent-search": {
      "command": "npx",
      "args": ["-y", "patent-search-mcp-server"],
      "env": { "PATENT_SEARCH_API_KEY": "psg_live_..." }
    }
  }
}

Configure in Cursor

Settings → MCP → Add Server. Same JSON shape as Claude Code.
