`get_trademark_by_serial`

Pack: trademarks · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/get_trademark_by_serial for the schema, then POST the same URL with its arguments for the data.

Look up one US trademark by its 8-digit serial (application) number: mark text, current status and live flag, registration number, owners of record, attorney of record, filing/registration/publication/renewal dates, filing basis, international classes and goods/services, with data_as_of. Keyless. Optional api_key switches to USPTO’s TSDR case-status record instead.

Parameters

Name	Type	Required	Description
`serial_number`	string	yes	USPTO serial number (e.g., “79153306”)
`api_key`	string	no	Optional USPTO TSDR API key (free at account.uspto.gov/api-manager). Omit for the keyless register record.
