Below note is WIPO rule at the time of writing
WIPO principle
Priority documents are classified as 'confidential' with the exception of unpublished documents hosted by the PCT which are classified as 'highly confidential'. As a result, unpublished PCT documents must be stored at WIPO/UNICC facilities, not public cloud. However, this data may transit through public networks and through services hosted on public cloud through an encrypted channel.
In practical terms, this means that PCT international applications from RO/IB that are used a priority documents cannot be stored in AWS however they can be in transit via AWS services.
Consequently, in DAS framework, any priority documents that are based on RO/IB PCT applications will be accessed in transit only, the rest will be able to be stored in and retrieve from AWS.
