The Federated European Patent Register (Federated Register)


The Federated Register view displays official bibliographic and legal status data relating to European patent documents in the national post-grant phase as made available to the EPO by the national offices of the designated contracting states and extension states participating in this service at the time the application is granted.

Information on the content provided by each national patent office currently integrated into the Federated Register service can be found on the EPO website.

The data provided in the common overview (table) contains the following bibliographic and legal status information:

     •   the country code
     •   the status of the patent document
     •   the application number
     •   the number under which it is published
     •   the proprietor
     •   the invalidation date
     •   whether or not the patent is currently in force
     •   when renewal fees were last paid
     •   when the national register was last updated


Where available, there is also direct hyperlink access to the relevant national patent registers so users can find out more about the document in the national phase. Again, links will be available only to the registers of those designated contracting states and extension states participating in the Federated Register service at the time of grant.

The section National patent registers displays ALL designated, contracting, extension and validation states, irrespective of whether or not they provide the service or have deep links to their registers. You may also find the register you are looking for in the list of national patent offices on the EPO's Useful links web page.

Status descriptions

A list of the various legal and bibliographic status descriptions is available in the Help topic Federated Register statuses. Details of coverage and the type of data provided by each national patent office may be displayed by clicking the relevant country code in the list of countries under Federated Register content on the EPO website.

Invalidation date

The invalidation date is the date when the decision on the invalidation was taken. It can be the date of one of the following events:

     •   patent withdrawn
     •   patent revoked
     •   patent lapsed
     •   patent expired


The date shown in the Federated Register is the most recent date provided by the national office concerned.

Not in force since date

The not in force since date is the date on which the rights conferred by the patent are no longer considered to be in force in the country concerned.

Note: The not in force since date may or may not be the same as the invalidation date, depending on the case in question and the national patent granting procedure concerned.


Please note that responsibility for the accuracy or quality of the data displayed lies entirely with the national patent office concerned, including but not limited to the completeness and fitness of the information for specific purposes.
