Note: The International Bureau encourages PCT applicants to start using ePCT-Filing, which is available for online filing at 55 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, RO/KR, RO/US that do not accept direct filings using ePCT. We recommend filing via browser-based ePCT in particular if you have issues downloading or installing the PCT-SAFE software. If you do not already have a WIPO account, please go to https://pct.wipo.int to create one, and then set up strong authentication in order to access the 'Create new IA' feature to prepare international applications.
