PCT Receiving Office Guidelines

Chapter IX: Nucleotide and/or Amino Acid Sequence Listing

General

222. The receiving Office examines the check list in Box No. IX of the request for reference to sequence listings and checks whether any sequence listing has been filed as part of the description. If the applicant furnishes a single sequence listing on the same date as the international application, but the check list contains no indication that a sequence listing forms part of the international application, the receiving Office corrects the check list ex officio to indicate that the sequence listing forms part of the international application, in conformity with the requirement of Rule 5.2 that the international application shall contain a sequence listing where there is disclosure of one or more nucleotide and/or amino acid sequences. Where the applicant furnishes multiple sequence listings on the same day as the international application, but the check list contains no indication that one of the sequence listings forms part of the international application, the receiving Office should seek clarification from the applicant noting the requirement of Rule 5.2.

222A. The receiving Office examines whether the check list appropriately indicates the relevant accompanying items in Box No. IX, items 8 and 9. If applicable, it also verifies that the type and number of physical data carriers on which the sequence listing is contained are as indicated. If there is any inconsistency, the check list may need to be corrected. The receiving Office transmits to the International Searching Authority any sequence listing (and any accompanying statement) furnished to it for the purposes of international search, whether submitted together with the international application or subsequent to the filing of the international application (Rule 23.1(c) and Section 313(c) as outlined in paragraph 290).
