Patent Connector 1.2: Office Action Search and Trademark Lookup

03 Apr 2026 — 2 min read

Patent Connector version 1.2.0 adds USPTO office action search and trademark lookup tools. These pull data from the new ODP endpoints that USPTO migrated from the legacy Developer Hub. The underlying Go client library was updated to version 1.4 to support these APIs.

Office Action Tools

You can now search office action records directly from your ChatGPT or Claude conversation. The tools cover rejections, citations, and enriched citations.

Practical examples of what you can ask:

"Has application 17/248,024 received any office actions?"
"Find all 101 rejections with an Alice indicator in art unit 2176"
"What prior art was cited against this application?"
"Show me enriched citation data for recent office actions in class 709"

The rejection search includes filters for all major rejection types - 101, 102, 103, 112, and double patenting - plus patent eligibility indicators for Alice, Bilski, Mayo, and Myriad. Useful for portfolio analysis or prosecution strategy research.

Trademark Tools

Trademark Status & Document Retrieval (TSDR) is now available as a set of MCP tools. You need a separate API key from account.uspto.gov, which you configure in Patent Connector alongside your patent API key.

What you can do:

Look up trademark status by serial number - owner info, filing dates, goods/services classifications, prosecution history
List all filed documents for a trademark case
Download specific documents as PDFs - Notices of Allowance, office actions, registration certificates
Retrieve trademark logo images
Batch lookup across multiple serial or registration numbers

The trademark image tool extracts the JPEG drawing from the official DRW document and returns it directly. How well that works depends on your chat client - more on that in a separate post about MCP and images.

Available Now

Patent Connector 1.2 is live. Add your TSDR API key in the settings, then reconnect your MCP client - most clients need a reload or restart to pick up new tools. If you're new, sign up at patent.dev/patent-connector and follow the setup instructions.

The full list of available tools now includes patent search and retrieval (EPO, USPTO, DPMA), PTAB proceedings, office action search, and trademark lookup.

MCP Has an Image Problem

I added trademark image retrieval to Patent Connector. The MCP specification defines exactly how a server should return images to a client. I implemented it by the book. Then I tested it across clients and the results were all over the place. What the Spec Says The MCP specification defines

USPTO ODP Go Client: Office Action and Trademark APIs

Version 1.4 of the uspto-odp Go client library adds two major API categories: Office Action search and Trademark Status & Document Retrieval (TSDR). USPTO migrated both from the legacy Developer Hub into the Open Data Portal, and the library now covers all of them. As with previous releases, I

Bulk File Loader v1.0.1: German Patent Office Downloads

Bulk File Loader reached version v1.0.1 with a new data source: the German Patent and Trademark Office (DPMA). The application now downloads bulk patent data from DPMA alongside existing sources, built on top of the dpma-connect-plus Go client library I released earlier. What It Does Bulk File Loader

Patent Connector MCP Server - New Release v1.1.0

My consulting philosophy: never talk about something you don't fully understand and know. So when MCP came up as a topic, I built a patent MCP server to get real implementation experience. I also found the concept behind MCP very interesting - a standardized protocol for giving LLMs
