What Is ST26 and Why It’s Important
The patent world for biotechnology has changed with the introduction of the ST26 standard. This rule, created by WIPO, requires all biological sequence listings to be submitted in a special XML format. If you’re filing a new patent or updating an old one, it’s important to follow this format correctly.
Earlier, ST.25 was used, but it had many limits. With ST26, everything is more detailed, better organized, and easy to check. However, making a correct ST26 file can take time and knowledge. Even a small error can delay your application or lead to rejection.
What’s New in the ST26 Format?
The ST26 format brings many changes that offer stronger protection but are harder to manage without technical skills. Some of the key updates include:
Using XML-based format instead of plain text
Accepting more sequence types, including D-amino acids and branched molecules
Asking for better labeling of each sequence’s parts
Requiring extra information about changes in residues
All these features help patent offices understand your invention better. But at the same time, preparing these listings without help can be stressful and confusing.
