PCT Receiving Office Guidelines

Chapter IX: Nucleotide and/or Amino Acid Sequence Listing

General

222. Any sequence listing part of the description must comply with WIPO Standard ST.26 (Rule 5.2(a), Section 208 and paragraph 4 of Annex C of the Administrative Instructions).  Under this Standard, sequence listings must be filed in XML format.  The receiving Office examines the check list in Box No. IX of the request for reference to a sequence listing and checks whether any sequence listing in ST.26 XML format has been filed as part of the description.  If the applicant furnishes a sequence listing in ST.26 XML format on the same date as the international application, but the check list contains no indication of the sequence listing part of the description, the receiving Office corrects the check list ex officio to reflect the sequence listing as part of the description (paragraph 26 of Annex C of the Administrative Instructions).  If the sequence listing has been furnished on physical data carrier(s), the receiving Office also verifies that the type and number of physical data carriers are as indicated on the check list.  If there is any inconsistency, the receiving Office ex officio corrects the check list.
