Espacenet / EPO OPS
The European Patent Office's worldwide patent search, accompanied by the Open Patent Services REST API. The API requires an OAuth key (a free tier exists), so we currently link to the Espacenet search interface instead. Use it to search the EPO's worldwide patent database. Flagged as degraded: the site may present a verification challenge before loading.

Son utilité et son fonctionnement
Espacenet is the European Patent Office's own search system and the authoritative source for European patent documents, covering filings from 1836 to the present across more than 100 countries. It is particularly strong for EPO filings, PCT international applications, and detailed legal status information that is harder to find elsewhere. Echo links you to the Espacenet search interface where you can look up patents by keyword, classification code, applicant, or patent number. Note that the site may occasionally present a verification challenge.
Ce qu’elle contient
Over 150 million patent documents from more than 100 countries, spanning from 1836 to the present, making it one of the largest freely accessible patent databases in the world.
