Patent Sequence Search and the Future of Biotech Patent Research

The process of searching for patents in biotechnology can be challenging as the key technical data is not necessarily captured in simple language. A protein, a DNA sequence, an antibody, or a genetic construct can be described in a patent using identifiers, sequence listings, scientific terminology and references throughout related applications. With Patent Sequence Search, scientists are provided with a tool to look at that biological data directly and link it to pertinent patent data.


This is important to companies, researchers and law firms in the USA, as biotechnology patents become more specific and competitive. A standard keyword search can be helpful, but is not always enough for an underlying invention that relies on biological sequences.


Why Sequence Data Changes the Search


Typical patent searches start with words. Research is started with the biological information in sequence.


A researcher may need to find a specific sequence of nucleotides, amino acids, a specific variant of a protein or a related biological structure. Two patents may claim the same subject matter, but with entirely distinct terms, but may show a much greater technical relationship through their sequence information.


This is particularly beneficial for therapeutic, diagnostic, agricultural biotechnology, vaccine and genetic engineering applications. The search may not be restricted to the description of an invention. It can review a technical disclosure and the underlying sequence information that is part of the disclosure.


Similarity Can Matter More Than Exact Matches


While an exact sequence match is easy, research in biotechnology is not always easy. Variants can be derived from a sequence by small changes that can have related functions, and researchers might have to explore similarity, not one exact match.


There are tools available for comparing sequences of biological material that can assist in finding related biological material in patent documents. The matches that result from this still need to be interpreted technically. The fact that two sequences show a percentage similarity does not determine whether the sequences are the same function, same invention or relevant to a certain patent claim.


That distinction can be very easily missed.


The Patent Family May Tell a Bigger Story


Sequences in one patent don't often occur alone. Additional sequence information or technical explanation may be found in related applications, international filings, continuations, divisionals and others in the family.


When analysing a sequence, the family of patents surrounding the sequence should be followed rather than just the first document found to match the sequence. Claims, examples, figures, or sequence listings may be in different family members.


This can be especially beneficial for U.S.-focused research in the event that a business requires understanding of an invention developed across jurisdictions. One US publication could be just one of many parts of a larger patent history.


Where Sequence Research Becomes Especially Useful


Frequently, biotech firms require patent data beyond litigation. Research can be used to assist in early stage technology assessment, freedom-to-operate analysis, competitive intelligence, technology portfolio reviews, and technology licensing negotiations.


A Patent Sequence Search can assist in answering questions like:


  • Does there exist any earlier biological sequence in a prior art patent?

  • What are the related sequences in the disclosures of any company or inventors?

  • Do there exist similar sequences that are linked with a patent family?

  • What's the location of a specific sequence in technical disclosures?

  • Is the sequence used for other biological purposes?


The answers are not necessarily the solution to a legal or scientific issue. They provide specialists with a more informed basis for further analysis.


The Overlooked Challenge of Sequence Versions


Another, less-talked-about thing is sequence versioning. Biological research is continually evolving and a patent document may include related sequences that have substitutions, deletions, insertions, and the like.


The relationships may be missed by the researcher if he or she only records the name of a protein/gene. By keeping the actual sequence identifiers and briefly documenting the similarities and differences of related sequences, a much clearer research trail may be maintained.


This is particularly advantageous in case of large patent portfolios. A sequence can be called by various identifiers and in various technical environments, and it is hard to track it easily with text.


Human Review Still Has a Place


This biological sequence information can be processed using modern databases and computational tools to a scale that would be hard to handle in a manual way. They are able to search for matches and similarities, as well as relationships and possibly relevant patent documents.


However, search results do not equate to analysis. Researchers should be aware of the biological context, dates, patent relationships and search intent. A sequence that has similar technical features may be of minor or major importance in one investigation and the other.


Citius Minds collaborates on patent analytics and IP research, including sequence-based research for complex tech areas. What is useful, is not just an expanded body of patent literature. It's a record of inquiry that simplifies technical relationships.


What Better Sequence Research Looks Like


When it comes to sequence research, everything is done to be organized from the start. Researchers need to keep sequence identifiers, summarize the pertinent patent publications, follow up the family relationships and record the reasons for a specific match to be considered in greater detail.


It also assists to differentiate discovery from interpretation. A database can generate hundreds of possible matches but only a subset of those should be thoroughly evaluated technically. Having those stages distinct will help to limit noise and ease review later on.


In biotech, this practice can be particularly beneficial, particularly when research is used to support patent, licensing, product development, or competitive positioning decisions for US companies.


The Next Chapter of Biotech Patent Research


The research of the biotechnology patent is progressing toward a deeper integration of textual, sequence, technical and structured patent information. Those who only study one of those layers may miss out on valuable connections.


But Patent Sequence Search takes another look at these connections using biological data that is not represented by the common keywords. When applied carefully, it can aid in the creation of a more complete picture regarding previous disclosures, inventions related to the disclosure and sequence-related patent activity.


If you have a complex biotechnology portfolio, the bigger opportunity is not just in identifying more documents for Citius Minds and teams. It's knowing how technical evidence pieces fit together to make patent research more accurate, retrievable and useful in making real world decisions.
