If a claim is filed with an agreement country agency, assume that the filing date
provided by the other country is correct even if you think an earlier protective filing
date may exist in that country.
Use the date most advantageous to the claimant if more than one date is shown by the
foreign agency.
If the claimant objects to the filing date established and alleges filing earlier
with the agreement country, contact the foreign agency and request proof of the earlier
filing.
