Register Plus is the place where the EPO stores all the publicly available information it has on European patent applications as they pass through the grant procedure. It is a free service available on the internet.

You can use Register Plus to:
Register Plus contains procedural information on all European patent applications from the moment they are published. It also contains all the public documents in the EPO's file (often called the "file wrapper").
The service provides direct access to both the European Patent Register (online procedural data) and Online Public File Inspection. It also allows you to access the data in esp@cenet and Open Patent Services (patent family information and INPADOC legal status).
If you are interested in tracking specific European patent applications, you can sign up for the free WebRegMT alert service, which will automatically send an e-mail alert every time something happens to any of these applications in the course of the grant procedure.
Users can monitor up to 1 000 individual cases. They can elect to monitor not only their own files, but also third-party applications, and can choose one of two security options to ensure confidentiality.
