What is WIPO ST.25 and how does it relate to patent applications?
WIPO ST.25 is a standard for the presentation of nucleotide and amino acid sequence listings in patent applications. It was used for applications filed before July 1, 2022. The MPEP notes: “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…
Read MoreWhat are the Sequence Rules under WIPO ST.25?
The Sequence Rules under WIPO ST.25 are guidelines established by the World Intellectual Property Organization (WIPO) for the standardized presentation of nucleotide and amino acid sequences in patent applications. These rules ensure consistency and facilitate the examination and searching of sequence listings in patent documents. According to MPEP 2421, these rules provide a standardized format…
Read MoreWhen do the Sequence Rules apply to patent applications?
The Sequence Rules apply to patent applications containing nucleotide sequence and/or amino acid sequence disclosures filed under WIPO ST.25. However, it’s important to note that there’s a cutoff date for the applicability of these rules. According to MPEP 2420: “[Editor Note: This section is not applicable to applications filed on or after July 1, 2022,…
Read MoreWhat are the requirements for content of a “Sequence Listing” part of the specification under WIPO ST.25?
The requirements for the content of a “Sequence Listing” part of the specification under WIPO ST.25 are outlined in 37 CFR 1.823. However, it’s important to note that these requirements are not applicable to all patent applications. As stated in the MPEP: “[Editor Note: This section is not applicable to applications filed on or after…
Read MoreWhen did the requirements for Sequence Listings change?
The requirements for Sequence Listings in patent applications changed on July 1, 2022. This is clearly stated in the MPEP: “[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).]” For applications filed before July…
Read MoreWhat are the key compliance requirements for sequence listings under WIPO ST.25?
Key compliance requirements for sequence listings under WIPO ST.25 include: Compliance is not a filing date, 35 U.S.C. 112, 35 U.S.C. 119/120, or per se new matter issue. Compliance can be achieved via amendment. The “Sequence Listing” is an integral part of the application. A replacement “Sequence Listing” must be used for amendments. Angle brackets…
Read MoreWhat are the requirements for international applications disclosing nucleic acid or amino acid sequences?
For international applications subject to WIPO ST.25 requirements that disclose nucleic acid or amino acid sequences, specific rules apply. MPEP 2420 states: “See PCT Rule 5 and Rule 13ter, and MPEP § 1823.02 and § 2422, for the requirements under the PCT for international applications subject to WIPO ST.25 requirements and that disclose nucleic acid…
Read MoreHow are modified bases represented in nucleotide sequence listings?
According to MPEP 2422, modified bases in nucleotide sequence listings can be represented as follows: The modified base can be represented as the corresponding unmodified base in the sequence itself. The modification must be further described in numeric identifier <223> of the Feature section of the “Sequence Listing”. Specific symbols for modified bases may be…
Read MoreWhat software can be used to generate WIPO ST.25 compliant sequence listings?
The MPEP recommends using PatentIn Version 3.5.1 software for generating sequence listings that comply with WIPO ST.25 standards. According to MPEP 2422: “PatentIn Version 3.5.1 software (see MPEP § 2430) generates sequence listings that meet all of the requirements of WIPO Standard ST.25 (2009).“ This software ensures that the generated sequence listings meet both USPTO…
Read MoreWhat are the standard single-letter codes for modified and unusual nucleotides in WIPO ST.25?
What are the standard single-letter codes for modified and unusual nucleotides in WIPO ST.25? WIPO ST.25 provides standard single-letter codes for modified and unusual nucleotides in sequence listings. According to MPEP 2423: “The nucleotides listed in Appendix 2, Table 2, are the only permitted nucleotides. Where a sequence includes “other” nucleotides, they must be represented…
