About EPO Open Patent Services

PatZilla uses the Open Patent Services (OPS) provided by the European Patent Office (EPO) to display bibliographic data of patent documents. See also https://ops.epo.org/ for more information about this service.


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. The number of documents available recently passed the 100-million mark.

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
