Upon filing a patent application, the USPTO mails a filing receipt.  The domestic and foreign claim of priority is stated and should be checked to make sure that it reflects the claim of priority that the inventor intends.  Otherwise, the patent owner may not be able to cure the defect when trying to sue an infringer after it issues as a patent.  If it can be fixed after it matures into a patent, the costs are much higher than the costs to fix while the patent application is still pending.
