Model Context Protocol

GleanMark for Claude

Give Claude live access to all 14 million U.S. federal trademark records — search, likelihood-of-confusion analysis, TTAB proceedings, and prosecution history. Connect your GleanMark account and it can work your own portfolio too.

Add to ClaudeTry the search first

Public trademark search works with no GleanMark account.

Two ways to use it

The connector behaves differently depending on whether you have linked a GleanMark account.

Public trademark research

No account required

Ask Claude anything about the federal register and it pulls live records instead of answering from memory. Searching, comparing marks, researching owners and law firms, reading TTAB history, and reviewing prosecution files all work anonymously.

Good for founders checking a name, marketers vetting a campaign, and attorneys doing a fast first look.

Your portfolio, inside Claude

Connect a GleanMark account

Sign in once and Claude can reach the same workspace you see in GleanMark: your clients, portfolios, docketed deadlines, watch alerts, recent office actions, and risk summaries — with the public research above still available in the same conversation.

This is the Markus experience, in whichever assistant you already work in.

Adding GleanMark to Claude

  1. 1

    Open Claude settings

    In Claude, go to Settings and then Connectors.

  2. 2

    Add a custom connector

    Choose to add a connector and paste the GleanMark endpoint below.

  3. 3

    Connect

    Claude registers with GleanMark automatically. Nothing else to configure for public trademark research.

  4. 4

    Sign in for portfolio access (optional)

    To reach your own clients, portfolios, deadlines, and alerts, approve the sign-in prompt with your GleanMark credentials. You can disconnect at any time from the same screen.

Connector endpoint

https://gleanmark.com/mcp

Transport: streamable HTTP. Authentication is optional — OAuth 2.0 with PKCE, handled by Claude when you choose to sign in.

Other MCP clients

The same endpoint works in any MCP-compatible client. Clients that cannot complete an OAuth flow may instead send a GleanMark API key as a bearer token — generate one in API settings.

Revoking access

Disconnect the connector in Claude, or revoke the key in API settings. Access ends immediately; disconnecting never affects your GleanMark data.

What you can ask

Ask in plain language. Claude picks the right lookup and cites live records back to you.

Search & clearance

Name, owner, phonetic, and design-code search across every U.S. federal record.

  • “Is there already a trademark for LUMINARA in skincare?”
  • “Find marks that sound like KWIKSET.”
  • “Which USPTO design code covers a crown?”

Likelihood of confusion

Side-by-side comparison and DuPont-factor analysis between two marks.

  • “Compare NIKE and NYKE for likelihood of confusion.”
  • “Run a DuPont analysis on SUMMIT versus SUMMIT PEAK in class 25.”

Owner & firm intelligence

Who owns what, which firms file most, and how a correspondent specializes.

  • “Who are the top trademark filers in class 9 in 2025?”
  • “Which companies own trademarks for COMET?”
  • “What does the trademark practice at Fross Zelnick look like?”

TTAB proceedings

Oppositions and cancellations, party history, and proceeding documents.

  • “Show me recent TTAB oppositions involving Monster Energy.”
  • “How often does this owner oppose other applications?”

Prosecution history

Office actions, refusal grounds, timelines, and examiner profiles.

  • “Why was this application refused?”
  • “What is the registration rate for this examining attorney?”

Your portfolio (requires connecting)

Clients, portfolios, deadlines, alerts, and risk — your own GleanMark data.

  • “What in my portfolio needs attention?”
  • “Which of my deadlines fall in the next 60 days?”
  • “Summarize what happened across my clients this week.”

How it handles your data

Read-only

Every tool only reads. Nothing files, edits, deletes, or spends money on your behalf.

Scoped to your account

A connected account reaches exactly the workspace data it already has in GleanMark — nothing more, and nothing belonging to anyone else.

Nothing borrowed from Claude

The connector never reads your chat history, memory, or uploaded files. It receives only the question at hand.
