What happens if the certified copy is filed after the issue fee is paid?
If the certified copy of the foreign application is filed after the date the issue fee is paid but prior to the date of grant of the patent, it will be placed in the file record but there will be no review of the papers. The patent when published will not include the priority claim. A certificate of correction under 35 U.S.C. 255 and 37 CFR 1.323 can be filed to have the priority claim considered after publication of the patent.
