Professional Sequence Listing Services for Patent Success
Don’t let complex sequence listings delay your patents. Our expert team delivers perfectly formatted, PTO-compliant ST.26 listings – new or converted from ST.25- that pass validation first time sequence listing services. Trusted by leading patent attorneys and IP departments, we process thousands weekly, ensuring reliable, accurate support for your valuable innovations.
Sequence Listings: Essential for Biotech Patents
Sequence listings are an essential component of biotechnology patents. They serve to differentiate the invention from prior art, preclude competitors from obtaining overlapping patents, and facilitate future research and development. Mistakes in the published sequences can cause a total loss of patent protection for valuable inventions.
Our services provide the scientific and technical know – how to transform raw sequence data into patent-acceptable listings (e.g., XML according to ST.26). We guarantee that nucleotide or amino acid sequences are correctly formatted, correctly annotated, and correctly cross-referenced. Our Patent Sequence Listings Services are specially designed to support patent agents and patent attorneys at law firms or corporations.

What Clients Say
Real World Case Studies
Case Study 1: ST.26 Compliance for WIPO Filing
We were approached by a mid-size European biotech company with an urgent desire to file an international patent application via WIPO that included a huge number of DNA and amino acid sequences. The internal team of the customer lacked software tools to generate XML-compliant sequence listings and was not familiar with the recently approved WIPO ST.26 standard.
Our Solution:
- Collected all of the sequence data from client.
- 50+ sequences were converted into an XML format using WIPO Sequence software.
- Confirmed that the organism, feature annotation, and qualifier formatting were assigned correctly.
- Prepared Final XMLs format sequence data in three business days.
- Worked with the client’s lawyer to ensure a seamless submission.
Project Outcome:
- The sequence listing was approved by WIPO.
- Client saved time and avoided expensive delays
Case Study 2: Fixing Sequence Listing & Resubmission
A Japanese biotech client’s law firm approached us after their patent application was rejected due to the sequence listing not being complete in terms of ST.26 compliance. The initial document had been drafted with the legacy ST.25 standard and contained inappropriate annotations.
Our Solution:
- Collected the rejected sequence listing and the underlying sequence data from client.
- Using WIPO Sequence tools, the listing was completely rebuilt.
- Converted to ST.26 format from ST.25 format and accurately allocated organism, molecular type, and annotations.
Project Outcome:
- Correct sequence listing recognized by the patent office.
- Our client trusted our procedure and gave us more cases through referrals.

Frequently Asked Questions
What are sequence listings?
A sequence listing contains nucleotide and/or amino acid sequences disclosed in a patent application and forms part of the description. It includes descriptive information about each sequence, known as annotations, and conforms to the requirements of the relevant WIPO standard (ST.25 or ST.26). It allows the sequence data of an invention to be searchable within an IP office and in publicly available databases (e.g., INSDC databases).
Why are sequence listings required?
They ensure uniformity in disclosure of biological sequences across patent applications worldwide, facilitating examination and enabling efficient electronic data exchange between patent offices.
When is a sequence listing required?
A sequence listing is required when your patent application discloses one or more nucleotide or amino acid sequences that fall within the definition of sequence disclosure under applicable rules.
What is WIPO Standard ST.26?
ST.26 is the current global standard for sequence listings in XML format, replacing the older ST.25 standard. It became mandatory for all international patent applications filed on or after July 1, 2022.
How does ST.26 differ from ST.25?
ST.26 differs from ST.25 by using XML instead of plain text, requiring the inclusion of D-amino acids, branched sequence portions, and nucleotide analogs. It also allows more detailed annotations with feature keys and qualifiers, and prohibits sequences shorter than 10 nucleotides or 4 amino acids, which ST.25 permits.
Is ST.26 mandatory for all applications?
Yes, ST.26 is mandatory for all international patent applications (PCT) filed on or after July 1, 2022, and for many national/regional applications depending on local implementation.
Which sequences must be included in a listing?
All disclosed sequences with 10+ nucleotides or 4+ amino acids must be included, whether in claims, description, drawings, or sequence listing.
Are modified sequences required in sequence listings?
Yes, modified nucleotides and amino acids must be included and appropriately annotated according to ST.26 rules.
Can I include sequences shorter than the threshold?
Sequences shorter than 10 nucleotides or 4 amino acids should not be included in ST.26 sequence listings unless specifically required by local rules.
What software can I use to prepare ST.26 sequence listings?
WIPO’s free WIPO Sequence tool is the recommended software for preparing and validating ST.26-compliant sequence listings.
Where can I download WIPO Sequence?
WIPO Sequence can be downloaded from the WIPO website at www.wipo.int/standards/en/sequence.
Does WIPO Sequence validate my sequence listing?
Yes, WIPO Sequence includes a validation function that checks your sequence listing for compliance with ST.26 requirements.
What file format should I submit?
ST.26 sequence listings must be submitted in XML (XML = eXtensible Markup Language) format with a .xml file extension.
What is the maximum file size for sequence listings?
Size limits vary by patent office. For large files, consult your target patent office for submission options.
Can I submit a sequence listing after filing my application?
Yes, but late submission may require additional fees and cannot add new matter to the application.
How do I represent branched sequences?
Branched sequences should be represented as multiple linear sequences, with each branch represented separately.
How should D-amino acids be represented?
D-amino acids are represented using the same one-letter codes as L-amino acids but must include a “feature” annotation specifying “D-configuration.”
How do I represent non-conventional nucleotides or amino acids?
Use the most restrictive symbol possible (e.g., “N” for nucleotides, “X” for amino acids) and include appropriate feature annotations.
What character encoding is required for ST.26?
ST.26 sequence listings must use UTF-8 encoding.
What naming convention should I use for sequence listing files?
Follow your patent office requirements. For PCT applications, use the format “[application_number]_sequence_listing.xml”.
Are there language requirements for free text qualifiers?
Free text in qualifier values should be in English or include both original language and English translation.
What are common errors in sequence listings?
Common errors include inconsistent annotations, incorrect feature locations, missing mandatory qualifiers, and improper formatting of modified residues.
What happens if my sequence listing contains errors?
Sequence listing errors may result in requests for correction, potential filing date issues, or prosecution delays.
How can I correct a sequence listing after submission?
Correction protocols vary by jurisdiction. Generally, you must submit a replacement listing with a statement that the correction introduces no new matter.
