2422.02    The Requirement for Exclusive Conformance; Sequences Presented in Drawing Figures [R-07.2022]

[Editor Note: This section is not applicable to applications filed on or after July 1, 2022, having disclosures of nucleotide and/or amino acid sequences as defined in 37 CFR 1.831(b). See MPEP §§ 2412-2419 for guidance on WIPO ST.26 requirements for applications filed on or after July 1, 2022.]

For all applications that disclose nucleic acid and/or amino acid sequences that fall within the definition set forth in 37 CFR 1.821(a), 37 CFR 1.821(b) requires exclusive conformance to the requirements of 37 CFR 1.821 through 37 CFR 1.825 with regard to the manner in which the disclosed nucleotide and/or amino acid sequences are presented and described. This requirement is necessary to minimize any confusion that could result if more than one format for representing sequence data was employed in a given application.

Pursuant to 37 CFR 1.83(a), sequences that are included in sequence listings should not be duplicated in the drawings. However many significant sequence characteristics may only be demonstrated by a figure. This is especially true in view of the fact that the representation of double stranded nucleotides is not permitted in the "Sequence Listing" and many significant nucleotide features, such as "sticky ends" and the like, may only be shown effectively by reference to a drawing figure. Further, the similarity or homology between/among sequences may only be depicted in an effective manner in a drawing figure. Similarly, drawing figures are recommended for use with amino acid sequences to depict structural features of the corresponding protein, such as epitopes and interaction domains. The situations discussed herein are given by way of example only and there may be many other reasons for including a sequence in a drawing. However, when a sequence is presented in a drawing, the sequence must still be included in the "Sequence Listing" if the sequence falls within the definition set forth in 37 CFR 1.821(a), and a sequence identifier ("SEQ ID NO:X" or the like) must be used, either in the drawing itself or in the Brief Description of the Drawings.
