2422.02    The Requirement for Exclusive Conformance; Sequences Presented in Drawing Figures [R-07.2015]

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 nucleic acid 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 finger regions and Kringle regions. 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 the sequence identifier ("SEQ ID NO:X") must be used, either in the drawing or in the Brief Description of the Drawings.
