Law - PCT Invitation To Submit Sequence Listing

If an international application discloses a nucleotide and/or amino acid sequence, the description must contain a listing of the sequence in formats that comply with PCT rules. The formats are specified in WIPO Standard ST.23. Some receiving offices require that a machine-readable form of the sequence listing be submitted. One consequence of not submitting a machine-readable sequence listing is that the search or examination of the application may be performed to a limited extent (even though the full fee for the search and/or examination is paid). If the International Searching Authority or International Preliminary Examining Authority invites the applicant to submit the sequence listing in a required format, it must be submitted within 1 month of the date of mailing of the invitation or within the time limit fixed in the invitation, whichever is longer.

The position of the USPTO on this issue is described in the following section(s) of the Manual of Patent Examining Procedure (MPEP):
