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.
Public trademark search works with no GleanMark account.
The connector behaves differently depending on whether you have linked a GleanMark account.
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.
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.
In Claude, go to Settings and then Connectors.
Choose to add a connector and paste the GleanMark endpoint below.
Claude registers with GleanMark automatically. Nothing else to configure for public trademark research.
To run knockout and similar-mark searches, or to reach your own clients, portfolios, deadlines, and alerts, choose to sign in, then log in with your GleanMark account on the page that opens and pick the workspace Claude should use. What Claude can run follows your plan, the same as in the app. Developers can connect with an API key on the same page. You can disconnect at any time from the same screen.
Connector endpoint
https://gleanmark.com/mcpTransport: streamable HTTP. Authentication is optional — OAuth 2.0 with PKCE, handled by Claude when you choose to sign in.
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 — create one under Settings → Account → API access (included with Professional, Firm and Enterprise plans).
Disconnect the connector in Claude, or end the connection under Settings → Account → Connected apps in GleanMark. If you connected with an API key, revoking the key also ends that connection immediately. Public trademark research keeps working without an account, and disconnecting never affects your GleanMark data.
Ask in plain language. Claude picks the right lookup and cites live records back to you.
Name, owner, phonetic, and design-code search across every U.S. federal record.
Side-by-side comparison and DuPont-factor analysis between two marks.
Who owns what, which firms file most, and how a correspondent specializes.
Oppositions and cancellations, party history, and proceeding documents.
Office actions, refusal grounds, timelines, and examiner profiles.
Clients, portfolios, deadlines, alerts, and risk — your own GleanMark data.
Nothing files, edits, deletes, or spends money on your behalf. Four research tools save their analysis to your own GleanMark account; everything else only reads.
A connected account reaches exactly the workspace data it already has in GleanMark — nothing more, and nothing belonging to anyone else.
The connector never reads your chat history, memory, or uploaded files. It receives only the question at hand.

Public search costs nothing and needs no account. Connect a GleanMark workspace when you want your own portfolio in the conversation.
