How should amendments to ASCII plain text file submissions be made?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

To amend ASCII plain text file submissions (e.g., Sequence Listings, Large Tables, or Computer Program Listing Appendices):

• Submit a replacement ASCII plain text file
• Include a request to incorporate the replacement file by reference
• Provide a statement identifying the location of all changes
• Include a statement that the replacement file contains no new matter
• For read-only optical disc submissions, provide replacement discs labeled as “REPLACEMENT MM/DD/YYYY”

As stated in MPEP 608.05: Any amendment to the information on a read-only optical disc must be by way of a replacement read-only optical disc, in compliance with 37 CFR 1.58(g) for “Large Tables”, 37 CFR 1.96(c)(5) for a “Computer Program Listing Appendix”, and 37 CFR 1.825(b) for a “Sequence Listing” or a CRF of a “Sequence Listing”, and 37 CFR 1.835(b) for a “Sequence Listing XML”.
