Summary
Connects to the USPTO's Trademark Status and Document Retrieval (TSDR) system for programmatic trademark lookups. Exposes three tools: serial number search, registration number search, and document retrieval for prosecution history like office actions and responses. Requires a free USPTO API key from account.uspto.gov. Hosted via Pipeworx gateway at gateway.pipeworx.io/trademarks/mcp with streamable HTTP transport. You'd reach for this when building legal research tools, competitive analysis dashboards, or any application that needs to verify trademark status, ownership details, or filing classifications without manually searching the USPTO database.
