European Patent Register

The European Patent Register is the most complete and up-to-date source of publicly available procedural information on European patent applications as they pass through each stage of the EPO granting process and on European patents with unitary effect.

This free online service contains procedural and legal information on all European patent applications from the moment they are published, and on Unitary Patents from the moment that unitary effect has been requested. It includes links to the patent registers of many EPO member states, showing the status of European patents after grant, when national patent offices take over responsibility for them, as well as information on the opt-out from the exclusive competence of the Unified Patent Court.

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
  • see whether or not unitary effect has been requested or registered
  • find out if a European patent has been opted-out

Global Dossier

Applicants often file patent applications for the same invention at multiple patent offices. Global Dossier brings these documents together in one place, to give you access to the correspondence (or “file wrapper”) between applicants/attorneys and the offices concerned for Canadian, Chinese, European, Japanese, Korean, US and PCT applications. It also offers you automatic machine translations of Chinese, Japanese and Korean documents into English.
