mcp-trademark

USPTO Trademark Watcher — both an MCP server (for Claude/Cursor/Windsurf) and a standalone CLI (for cron + email alerts).

Why this exists

CompuMark and Corsearch charge $50–$500/mo for trademark watching. Smaller brand owners and indie founders want the same coverage at $19/mo, or a $149 lifetime license they install themselves. We give them:

1. MCP tools — search USPTO from inside Claude, watch your marks, review alerts conversationally.

2. CLI — same features as a script (cron-friendly).

3. Local SQLite — no SaaS dependency, runs offline once cached.

4. Similarity scoring that catches look-alikes (typo squatting), sound-alikes (phonetic conflicts), and salient-token overlap.

Pricing

• $19/mo per watched mark (managed)

• $149 lifetime self-host bundle (one-time)

• $499 lifetime + 5 marks managed for 12 months

Install (self-host)

cd C:\openclaw-products\mcp-trademark
python -m venv .venv
.\.venv\Scripts\activate
pip install -e ".[dev]"

CLI usage

tmwatch search "Acme"
tmwatch watch "Acme" --classes 009,042 --threshold 0.75 --email alerts@you.com
tmwatch watches
tmwatch scan
tmwatch alerts --days 30

MCP usage (Claude Desktop)

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "trademark": {
      "command": "python",
      "args": ["-m", "src.server"],
      "cwd": "C:\\openclaw-products\\mcp-trademark"
    }
  }
}

Then in Claude:

"Watch the trademark 'Pipely' in classes 009 and 042 and alert me on any filings scoring above 0.7."

Production roadmap

• Bulk-feed integration. Replace the on-demand client.search with a nightly download of the USPTO weekly bulk feed at https://bulkdata.uspto.gov/ + a local FTS5 index. This catches NEW filings that haven't been indexed by the search API yet.

• Semantic similarity via Claude (catches "Apple Music" vs "Music for the Apple"-style conflicts that string match misses).

• Email digest sender (currently records alerts; need an SES/Resend integration to actually mail them).

• Web dashboard (Next.js) for non-technical buyers.

• TM-5 international support (EUIPO, WIPO Madrid) for global watches.
