Any sequence listing submitted in PDF format (or on paper) on the application filing date is treated as the paper copy required by 37 CFR 1.821(c). If applicant submits a sequence listing in both a PDF file and an ASCII text file via EFS-Web on the application filing date, a statement that the sequence listing content of the PDF copy and the ASCII text file copy are identical is required. In situations where applicant files the sequence listing in PDF format and requests the use of the CRF of another application under 37 CFR 1.821(e), applicant must submit a letter and request in compliance with 37 CFR 1.821(e) and a statement that the PDF copy filed in the new application is identical to the CRF filed in the other application.
