The European Patent Register contains all the publicly available procedural information on European patent applications as they pass through each stage of the granting process.

This free online service contains procedural information on all European patent applications from the moment they are published. It includes links to the patent registers of many of the EPO member states, showing the status of European patents after grant, when the national patent offices take over responsibility for them.

You can use the European Patent Register to:

  • find out what stage in the procedure a European patent application has reached
  • see whether or not a European patent application has been granted
  • check whether any oppositions to a European patent have been filed
  • read correspondence between the EPO and patent applicants/attorneys

The European Patent Register is available free of charge, 24 hours a day, 7 days a week.

It is not intended for bulk data retrieval and users are limited to ten search-related actions per minute. The service does not support automated searches (robots) and will deny access to any robots it identifies.

For more details please read our fair use charter.

Federated Register

The Federated European Patent Register displays data relating to European patents in the post-grant phase. This information is made available by the national offices of the states concerned.

Global Dossier

Patent applications for the same invention are often filed at multiple offices. Global Dossier brings together documents from different offices relating to the same invention. It provides you with the correspondence between the applicants, or their patent attorney, and the Office (this correspondence is often called the "file wrapper") for Chinese, Japanese, Korean and US patent applications. It also offers you automatic machine translations for Chinese, Japanese or Korean documents into English.

Global Dossier is available from the European Patent Register and Espacenet.
