What happens if there’s a discrepancy between the USPTO’s date stamp and the date on the correspondence?

If there’s a discrepancy between the USPTO’s date stamp and the date on the correspondence, the USPTO’s date stamp is generally considered the official receipt date. However, if an applicant can provide clear evidence that the correspondence was received earlier than the date indicated by the USPTO’s stamp, the earlier date may be recognized as the official receipt date. This situation might occur due to clerical errors or delays in processing incoming mail.
