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
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
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 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
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
I've released a Go client library for the German Patent and Trademark Office's Connect Plus API. The library provides access to all three DPMA services - patents and utility models, designs, and trademarks - through a clean, production-ready interface. Technical Approach No official OpenAPI specification exists
Thomson Reuters down as much as 18%. RELX down 14%. Wolters Kluwer down 13%. Not because patent attorneys or contract lawyers became obsolete, but because Anthropic showed that the software wrapping their workflows can be replicated with an open-source plugin. The expertise is fine. What's dead is the
Starting 2026 with a fresh release: https://github.com/patent-dev/bulk-file-loader is now open source. Bulk File Loader automates downloading patent bulk data from EPO and USPTO. Set it up once, configure your credentials, and let it handle the rest - scheduled syncs, progress tracking, and webhook notifications included. Features:
USPTO Open Data Portal 3.0 brings full API access to Patent Trial and Appeal Board data - IPR proceedings, trial decisions, appeal outcomes, and interference records going back to 1997. The uspto-odp Go client library has been updated to support all 19 new endpoints.
No single database contains all patent texts. Formats differ between authorities, API access typically requires payment, and OCR introduces errors. This guide explains the challenges of accessing patent text data and what it would take to create a truly open, global resource.
Patent Connector now supports the USPTO Open Data Portal (ODP) API, adding US patent full-text access alongside the existing EPO integration. While EPO provides excellent global coverage, it lacks full-text data for US patents. The new USPTO ODP API integration enables ChatGPT, Claude, and other AI assistants connected via MCP
I've built Patent Connector, a Model Context Protocol server now in open beta. It connects ChatGPT Desktop, Claude Desktop, and other MCP-compatible AI tools directly to patent databases - starting with the free EPO OPS API. Instead of manually searching patent databases, copying claims, and pasting them into
