Open Patent Services (OPS)

Open Patent Services (OPS) is a web service which provides access to the EPO's raw data via a standardised XML interface. It does this using RESTful architecture.

OPS data is extracted from the EPO's bibliographic, worldwide legal status, full-text and image databases. It is therefore from the same sources as the Espacenet and European Patent Register data.


With OPS you can:

  • add EPO data to your own software applications or in-house databases
  • develop tailor-made clients 
  • download large volumes of data
