search_trademarks
Pack: trademarks · Endpoint: https://gateway.pipeworx.io/trademarks/mcp
Search US federal trademarks by mark text — the clearance/knockout-search path. Find registered and pending marks by wordmark without knowing a serial or registration number, then filter by international class and live/dead status to see which marks are actually enforceable. Covers the full USPTO register (the tmsearch.uspto.gov Elasticsearch backend that replaced TESS). Keyless. Use this to check whether a proposed brand name conflicts with existing US trademarks. Returns wordmark, serial and registration numbers, status, live flag, international classes, goods/services, owner, and filing dates. For a name-availability check, set live_only:true and pass the relevant class (e.g. 35 for advertising/business, 42 for software/SaaS, 9 for downloadable software).
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
query | string | yes | Mark text to screen (e.g. “TenderBrief”). Matches the wordmark field. Advanced: pass fielded Lucene (e.g. ‘wordmark:apple AND ownerName:“Apple Inc”’) and it is used verbatim. |
international_class | string | no | Optional Nice class filter. Accepts “35”, 35, “IC 035”, or “035”. Common: 9 (software), 35 (advertising/business/retail), 42 (SaaS/tech services). |
live_only | boolean | no | If true, return only live marks (registered or pending) — the set that can actually block a new application. Default false (includes dead/abandoned/cancelled). |
owner | string | no | Optional owner-name filter (matches ownerName). |
limit | number | no | Results per page, 1-50 (default 20). |
offset | number | no | Pagination offset (default 0). |
