Can sequences be presented in drawing figures of a patent application?

Yes, sequences can be presented in drawing figures of a patent application, but there are specific guidelines to follow:

• According to 37 CFR 1.83(a), sequences included in sequence listings should not be duplicated in the drawings.
• However, the MPEP recognizes that “many significant sequence characteristics may only be demonstrated by a figure.”
• Examples of such characteristics include double-stranded nucleotides, “sticky ends,” and structural features of proteins like epitopes and interaction domains.
• When a sequence is presented in a drawing, it must still be included in the “Sequence Listing” if it falls within the definition set forth in 37 CFR 1.821(a).
• A sequence identifier (“SEQ ID NO:X” or similar) must be used, either in the drawing itself or in the Brief Description of the Drawings.

This approach allows for effective visual representation of important sequence features while maintaining compliance with sequence listing requirements.
