{"jsonrpc":"2.0","id":1,"method":"tools/list"}search_patents — Search USPTO patent applications and grants. Use `query` for free-text keywords ("lithium battery", "crispr", "machine learning"); all terms are required (AND), and you can quote a phrase to keep it together. Optional structured filters: `applicant` (exact corporate name as filed, e.g. "APPLE INC."), `inventor` (person name), `title` (words in the invention title), `number` (a specific application number), `filed_after` / `filed_before`, `granted_after` / `granted_before`. Common synonyms are understood — `assignee`, `company` and `owner` all reach `applicant`, and `keywords`, `q` or `text` all reach `query`. Results include title, application number, filing date, first applicant, all applicants, inventors, status, classification. `total` is the full match count but USPTO returns at most 25 records per search — narrow with applicant or a date range rather than raising `limit`. Powered by the USPTO Open Data Portal (data.uspto.gov).get_patent — Fetch a single USPTO patent application/grant by application number (e.g., "16/123,456" or "16123456"). Returns full metadata: title, inventors, classifications, status, prosecution events.search_inventors — Search USPTO patent applications by inventor last name. Returns matching applications with title, inventor list, and filing date.get_patent_assignments — Retrieve USPTO-recorded assignment/conveyance history for one patent application from the migrated Open Data Portal endpoint. Returns assignors, assignees, execution/recording dates, conveyance text, and reel/frame. A recorded assignment is notice of a submitted instrument—not a legal opinion on present title, validity, scope, liens, or chain-of-title completeness.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
