Fee Worksheet and Acknowledgment Receipt Issue
On Thursday, April 28 beginning at 3 a.m., and ending at 8 a.m., ET, EFS-Web experienced a technical issue and was unable to properly generate an Acknowledgement Receipt and Fee Transmittal for some submissions. If you calculated and paid fees, your payment was successfully recorded in our payment system; however, the fees selected were not recorded on the EFS-Web generated Fee Transmittal. You can verify successful fee payments in Financial Manager or via your credit card provider.
USPTO is working to provide Acknowledgement Receipts and Fee Transmittals. If your submission was affected, please check Private PAIR or Patent Center for confirmation of these documents after May 9. If you have questions, please contact the Patent Electronic Business Center (EBC) at (866) 217-9197 during their operating hours of 6 a.m., to midnight, Monday - Friday ET, or email ebc@uspto.gov.
