What do I need from the EPO to file documents online?

You need a EPO Account or smart card with a smart card reader (including software) and the Online Filing software itself.

Version 5.15 enables the use of the EPO account with two-factor authentication.

The EPO account for eOLF 5.15 works for EP and PCT submissions to the EPO as filing office, receiving office or in any other capacity.

If a National Office is chosen as filing office, receiving office, or in any other capacity, the EPO account with two-factor authentication will only work for those National Offices that have adapted their systems to support this option.

For more information about the phasing out the use of smart cards in 2024, see the dedicated FAQ.
