uspto-patents-mcp

US patent search, full-text retrieval, claim extraction, citation graph, weekly grant alerts. Pairs with sec-edgar-mcp and fda-approvals-mcp for the R&D / biotech / IP-law audience.

⚠️ UPSTREAM API MIGRATION REQUIRED (as of 2025/2026). USPTO sunset the PatentsView v1 API and migrated everything to the Open Data Portal at data.uspto.gov/odp. The new API requires registration + API key. This MCP's code shape is correct; only the upstream URL + auth method changes. Tracking issue: PatentsView v1 endpoints now 301-redirect to USPTO's transition guide. All tools will currently surface the migration message until the new endpoint is wired.

Status: code green, infra live (https://uspto-patents-mcp.prakhar-cognizance.workers.dev), tests passing, awaiting USPTO ODP API key + migration to v2 schema.

Audience

  • R&D engineers / scientists asking "has anyone patented this?"

  • IP lawyers prepping FTO (freedom-to-operate) opinions.

  • Biotech / pharma agents tracking patent-cliff dates.

  • Investor agents tracking competitive moats (cross-sells with sec-edgar-mcp).

Risk notes

  • USPTO bulk data is huge; precompute search indexes nightly via GitHub Actions, store in R2 (10GB free), serve via Worker. Don't try to live-search the full corpus.

  • PatentsView API has rate limits but is genuinely free.

  • USPTO sometimes restructures their APIs (annual). Build for graceful degradation.

Open / closed split

  • Open: PatentsView wrapper, basic search.

  • Closed: nightly bulk-data indexer + R2 storage, citation graph precomputation, subscribe/webhook engine.
