Frequently Asked Questions
What is the WIPO ST.26 standard?
WIPO ST.26 is the mandatory XML-based format for biological sequence listings in patent applications filed globally after July 1, 2022, replacing the older ST.25 format with expanded sequence coverage requirements.
Do I need to convert my existing ST.25 listings to ST.26?
Only if filing new applications or amendments that include sequence listings. Existing applications filed before July 1, 2022 can maintain their ST.25 format throughout prosecution.
What sequences must be included in ST.26 listings?
ST.26 requires disclosure of linear sequences with 10+ nucleotides or 4+ amino acids, including D-amino acids, branched sequences, and modified residues with specific annotation requirements.
How long does it take to prepare an ST.26 sequence listing?
Standard ST.26 listings are typically delivered within 3-5 business days. Rush service is available for urgent filings with delivery in 24-48 hours.
Can I create ST.26 listings myself?
Yes, using WIPO’s free WIPO Sequence software. However, complex sequence annotations and validation issues often require professional expertise to ensure compliance.
What happens if my ST.26 listing contains errors?
Patent offices will issue notices requiring correction, potentially delaying examination. Critical errors may affect your filing date or limit the scope of protection.
