Patents Mcp
Taps into the Google Patents public dataset on BigQuery to give Claude patent search and prior art discovery. You get three tools: keyword and inventor search across patents, full patent retrieval by publication number, and claims text extraction. Built in Go, uses a service account with BigQuery Job User and Data Viewer roles, and leans on the 1TB monthly free tier. Good for researching existing patents before filing, finding prior art for patent applications, or exploring what companies have filed in specific tech areas. The architecture keeps each tool self-contained, so extending it with new queries is straightforward.
