What Is ST26 and Why Does It Matter?
Patent applications involving biological sequences now follow a new international standard called ST26. This format, introduced by WIPO, replaces the old ST.25 system and is now required for sequence listings in most global patent offices.
Unlike the older format, ST26 uses XML to provide better structure and detail. This ensures that the information is easy to read and process. However, the format is more technical and requires proper formatting to avoid delays during submission.
Key Features of ST26 Format
ST26 offers several improvements to support modern biotechnology. These updates help make sequence data clearer and more complete for patent examiners. Important features of the ST26 format include:
- A fully structured XML format for clear presentation
- Support for branched sequences and D-amino acids
- Proper tagging of modified residues
- Enhanced annotation of sequence features and regions
These benefits improve quality but also require technical precision, making expert help very useful.
