5.066.   What needs to be included in the statement of reasons for the request to restore the right of priority?  The statement should indicate the reasons for the failure to file the international application within the priority period.  It should contain all the relevant facts and circumstances which would allow the receiving Office to determine that the failure to file the international application within the priority period occurred in spite of due care required by the circumstances having been taken or was unintentional.
