Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Read your Trademark Center docket” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "trademarkcenter.uspto.gov/get_docket",
    "input": {}
  }'

{
  "status": "completed",
  "data": {
    "applications": [
      {
        "serial_number": "99000417",
        "mark": "ACME TRAILWORKS",
        "status": "Non-final action e-mailed",
        "status_date": "2026-11-06"
      }
    ],
    "count": 1
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

Trademark Center’s own options

The USPTO's Trademark Center pages describe web forms and a docket, not an API. Trademark Center is the only way to apply, and forms are moving there from TEAS until spring 2027. Status and documents for any application or registration are in TSDR, looked up by serial or registration number.

Signing in to Trademark Center

Trademark Center signs you in with a USPTO.gov account and multi-factor authentication: an authenticator app, Okta Verify, or a FIDO2 security key or biometric authenticator. Email codes are no longer accepted. With Fous you sign in through the USPTO's own sign-in with your own account. The login is sealed with AES-256, never returned by the API or written to logs, and code and AI agents never see it.

Worth knowing

Forms are moving from TEAS until spring 2027

Each form stays in TEAS and Trademark Center for 2 to 3 months, then TEAS retires it. Section 8, Section 15, Sections 8 and 9 and Section 71 forms left TEAS after October 31, 2026.

New documents may not appear right away

The USPTO says a new document may not show up in TSDR immediately. A check for new documents is best compared with the last run, not with today's date.

Check status every three to four months

An application whose office action is not answered by the deadline abandons, and fees are not refunded. The USPTO recommends checking status at least every three to four months and keeping a copy of the TSDR status screen.

The Manage menu needs a signed-in account

Only customers signed in to their USPTO.gov account see Trademark Center's Manage menu, where the docket and saved drafts are. A docket method reads them signed in to your own account.
