Can sequence identifiers be used to discuss parts of a sequence?
Yes, sequence identifiers can be used to discuss or claim parts or fragments of a properly presented sequence. The MPEP provides guidance on this matter:
“Sequence identifiers can also be used to discuss and/or claim parts or fragments of a properly presented sequence. For example, language such as ‘residues 14 to 243 of SEQ ID NO:23’ is permissible and the fragment need not be separately presented in the ‘Sequence Listing XML.'”
This approach allows for precise referencing of specific portions of a sequence without the need to create separate entries in the Sequence Listing XML for each fragment.
