{"jsonrpc":"2.0","id":1,"method":"tools/list"}eps_publication_dates — List EPO European Publication Server publication dates (almost always Thursdays, weekly since 1978) with a real document count per date. Filter by "year" (e.g. "2026") or a "from"/"to" range (YYYYMMDD or YYYY-MM-DD); omit both to get the most recent dates. Use a returned date with eps_list_publications to see what was published that day.eps_list_publications — List every EP patent publication issued on one EPO publication date, with publication number, kind code, title and applicant(s). Returns the real total on that date before any filtering. "date" must be a real EPO publication date (get one from eps_publication_dates) — an arbitrary date fails loudly rather than silently returning nothing. "kind" filters to a kind code ("A1" newly-published application, "A2" application without search report, "A3" search report, "B1"/"B2"/"B3" granted-patent stages) or a bare letter ("A" or "B") for either family.eps_get_document — Fetch one EP patent publication as published by the EPO — bibliographic data, or the full text of its abstract, claims or description. Give "number" as a full id from eps_list_publications (e.g. "EP4819826NWA1", recommended) or a bare publication number ("EP4819826") plus "kind" ("A1", "B1", ...). Full claims/description text is reliably present for GRANTED (B-kind) patents and directly-filed (non-PCT) applications; a Euro-PCT national-phase entry (the common case) carries only the bibliographic record here because its full text was already published as a WIPO pamphlet — the response says which case it hit rather than returning an empty result.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
