When did the requirements for nucleotide and amino acid sequence data change?
The requirements for nucleotide and amino acid sequence data changed on July 1, 2022. The MPEP section notes: “[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…
Read MoreWhat are the symbols and format requirements for nucleotide and amino acid sequence data in patent applications?
The symbols and format requirements for nucleotide and amino acid sequence data in patent applications are outlined in 37 CFR 1.822. This regulation specifies the standards for presenting sequence data in patent applications. It’s important to note that “Appendices A through F referenced in 37 CFR 1.822 are reproduced in MPEP § 2422(I).” These appendices…

What are the rules for representing modified amino acids in WIPO ST.25 sequence listings? The representation of modified amino acids in WIPO ST.25 sequence listings follows specific rules as outlined in MPEP 2423: “Modified amino acids must be represented as the corresponding unmodified amino acids in the sequence itself if possible. Any modified amino acids…

How should gaps in nucleotide sequences be represented in WIPO ST.25 format? According to MPEP 2423, gaps in nucleotide sequences should be represented using a specific symbol in WIPO ST.25 format: “Gaps of indeterminate length in the sequence must be represented by a series of the lower case letter “n”, the number of “n” residues…
Read MoreWhat are the consequences of not complying with sequence listing requirements in patent applications?
Failure to comply with sequence listing requirements in patent applications can have serious consequences, as outlined in MPEP 2422: The application may be considered incomplete or defective Examination of the application may be delayed A notice to comply may be issued, requiring a response within a specified time frame Failure to respond properly may result…
Read MoreHow should branched sequences be represented in WIPO ST.25 format?
How should branched sequences be represented in WIPO ST.25 format? Branched sequences require special handling in WIPO ST.25 format. According to MPEP 2423: “A sequence that contains regions of specifically defined residues separated by one or more regions of consecutively branched residues comprising any one or more of the following: ‘J’, ‘O’, or ‘Z’, must…
Read MoreHow does WIPO Standard ST.26 differ from WIPO Standard ST.25 for sequence listings?
WIPO Standard ST.26 and ST.25 are different standards for sequence listings in patent applications: ST.26 applies to applications filed on or after July 1, 2022. ST.25 applies to applications filed before July 1, 2022. ST.26 requires sequence listings in XML format, while ST.25 uses a different format. ST.26 allows for a single, internationally acceptable sequence…
