get_patent_maintenance_status

Pack: patent-maintenance-fees · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/get_patent_maintenance_status for the schema, then POST the same URL with its arguments for the data.

Look up a US patent’s maintenance-fee history and in-force/expired status: every recorded maintenance-fee event (payments, surcharges, expiration for non-payment, reinstatement, entity-status changes) plus a computed status and a 4th/8th/12th-year fee-window breakdown (due date, grace-period end, whether paid). Give the patent number with or without commas (“10835610” or “10,835,610”). Design (D-prefixed) and plant (PP-prefixed) patents are statutorily exempt from maintenance fees and will report subject_to_maintenance_fees:false rather than a bare no-match. Sourced from USPTO’s Patent Maintenance Fee Events (public domain, covers patents granted 1981-09-01 to present), refreshed from the weekly bulk file — every response carries data_as_of. Keyless. Does NOT determine full-term (20-year) expiration or any non-fee reason a patent could be invalid — this pack covers maintenance-fee lapses only; pair with the patents pack for prosecution history.
