The "Espacenet" patent database

Espacenet is a European network of patent databases which is available online for free. This service is managed by the European Patent Office (EPO) in collaboration with national offices of EPO member states. The system has a simple interface which allows even inexperienced users to carry out searches in their own European language. This database has more than 60 million patent documents from throughout the world.

By accessing Espacenet via one of the national office websites, you can search through all patent requests or published patents from 1997-1998 until now, and sometimes earlier.

A certain number of national offices provide access to a larger number of publications.

The OPRI’s Espacenet server contains publications on national patents from 1984 to today.

The European Patent Register (EPO)

The online European Patent Register is a database which contains all published European patent requests, international patent requests (PCT) related to one or more member states of the European Patent Convention as well as published European patents.

For each of these files, bibliographic data and information on the procedure are available from the first publication until the patent is issued. The online register also contains many additional details on the exam, objections and appeals which are normally available by consulting the file.
