Tired of ST.26 sequence listings?

Haven’t you found a workflow since ST.26 came into effect, besides dragging everything into WIPO Sequence and doing a manual clean-up? Anxious to make mistakes? Collect the sequences in your application, put them in a simple template and share them securely. NLO generates the ST.26 compliant sequence listing for you.

Why use SQ List it! for your patent applications?

4 Advantages

How does SQ List it! build an ST.26?

The ST.26 XML file is built automatically via our proprietary platform based on the template you share. The automation saves time, eliminates human errors and accommodates complex listings. Putting in lengthy genomes or highly modified proteins is not an obstacle. At the same time, our smart solution flags potential issues such as:

  • duplicated sequences;
  • unexpected nucleotide;
  • amino acid patterns;
  • incompatible modifications.

Afterwards, the sequence listing is validated using WIPO’s validator. This workflow saves time and costs, while alerting you of potential issues before an application is filed.

Your ST.26 sequence data is secure

Handling your valuable data securely and responsibly is key. NLO processes your sequences without storing any data in the long term. A service level agreement regulates all security details. SQ List It! is a separate NLO service that does not lead to any further obligation to NLO.
