The International Bureau encourages PCT applicants to use ePCT-Filing, which is available for online filing at 82 receiving Offices, including RO/IB, and for preparing and validating the RO/101 data for submission to the e-filing systems of other receiving Offices such as RO/CA, RO/IL and RO/US that do not accept direct online filings.
We recommend filing via browser-based ePCT, thus avoiding any downloads and software updates.

As of July 1, 2022 the International Bureau no longer develops, distributes or supports PCT-SAFE software.
If you are still filing with PCT-SAFE we advise you to start using ePCT-Filing as soon as possible.
