How are nucleotide and amino acid sequences represented in patent applications?
According to MPEP 2422.01, nucleotide and amino acid sequences in patent applications are represented as follows: Nucleotide sequences: Represented by symbols set forth in 37 CFR 1.822(b) and Appendices A and B to 37 CFR part 1, Subpart G. Amino acid sequences: Limited to those in 37 CFR 1.822(b) and Appendices C and D to…
Read MoreWhat are the length thresholds for nucleotide and amino acid sequences requiring a “Sequence Listing”?
According to MPEP 2422.01, the length thresholds for nucleotide and amino acid sequences requiring a “Sequence Listing” are: An unbranched sequence of four or more amino acids An unbranched sequence of ten or more nucleotides The MPEP states: “Nucleotide and/or amino acid sequences as used in 37 CFR 1.821 through 37 CFR 1.825 are interpreted…
Read MoreWhat is a Sequence Identifier (SEQ ID NO) and how is it used in patent applications?
A Sequence Identifier (SEQ ID NO) is a unique number assigned to each disclosed nucleic acid and/or amino acid sequence in a patent application. According to MPEP 2422.01: “37 CFR 1.821(d) and 37 CFR 1.823(a)(5) require that each disclosed nucleic acid and/or amino acid sequence in the application appear separately in the “Sequence Listing”, with…
Read MoreWhat sequences must be included in the “Sequence Listing” of a patent application?
According to MPEP 2422.01, the following sequences must be included in the “Sequence Listing” of a patent application: All sequences, whether claimed or not, that meet the length thresholds in 37 CFR 1.821(a). Any sequence disclosed as a string of particular nucleotide bases or amino acids, regardless of whether the applicant considers it prior art.…
Read MoreHow should sequence variants be presented in a patent application?
According to MPEP 2422.01, sequence variants in patent applications can be presented as follows: Present a single, primary sequence in the specification and “Sequence Listing” by enumeration of its residues. Discuss and/or claim variants of that primary sequence without presenting each variant as a separate sequence in the “Sequence Listing”. Annotate the primary sequence in…
