If a Eurasian application contains an invention relating to sequences of nucleotides and/or amino acids, which are disclosed to characterize the invention and/or to allow its enablement, the description of the invention in the Eurasian application shall contain listings of these sequences in accordance with the requirements of WIPO ST.25 (Annex 1).
2. In accordance with Rule 23(8) of the Patent Regulations to the Eurasian Patent Convention (hereinafter – Patent Regulations), the listings of sequences of nucleotides and/or amino acids (hereinafter – listing), mentioned in Par.1 of the present Procedures, shall be presented on machine-readable carriers and in accordance with WIPO ST.25.Types of machine-readable carriers, which may be used for presentation of listings, as well as technical requirements to the fixation of the sequence listings on machine-readable carriers are given in Annex 2 to the present Procedures.

5. When presenting sequence listings in printed form, with attached machine-readable copies, the applicant shall present a declaration on the identity of the sequence listings on paper and on machine readable carriers. An indicative text of such a declaration is shown in Annex 3 to the present Procedures.
6. When a Eurasian application contains a machine-readable carrier with sequence listings, the “Other Documents” paragraph of the request for grant of a Eurasian patent shall indicate the type of the attached machine-readable carrier (for example, “CD”); “Declaration”, if it is attached.
7. If the sequence listing is presented on a machine-readable carrier of a different type than those, provided for under the present Procedures, or if the sequence listing is recorded not in compliance with the established technical requirements, the Eurasian Patent Office (hereinafter- EAPO) shall notify the applicant of the need to correct these deficiencies and replace the machine-readable carrier.
8. If the presented machine-readable carrier, containing the sequence listing, is damaged or is unreadable, the EAPO shall notify the applicant of the need to replace the machine-readable carrier.
9. In the absence of the required number of copies of the machine-readable carrier, the missing copies shall be produced by the EAPO at the expense of the applicant.
