US Trademark Search Skill (tm-search)

This skill enables an agent to search, validate, and analyze US trademarks via USPTO APIs.

Important: API Access Reality

The USPTO trademark search system (tmsearch.uspto.gov) uses AWS WAF bot protection on its Elasticsearch search backend. Direct keyword search via HTTP is not possible without browser automation. However, the TSDR details API (case lookup by serial number) works without authentication and returns JSON.

For keyword search, use one of these approaches:

1. Playwright/browser automation — drive the tmsearch.uspto.gov web UI (most reliable)
2. Third-party API — RapidAPI USPTO wrapper (requires API key, simpler to use)

For case status lookup by serial number, the built-in TSDR API works directly.
