Ten years of work. Millions spent. Then a letter from another company’s lawyers, a week before launch.
It happens, and the cause is usually ordinary. Someone else already patented part of what you built. It might be a protein, a gene sequence, or the way you make it. Making the discovery yourself does not mean you are free to sell it.
A Freedom to Operate (FTO) search checks whether you can launch your product without infringing someone else’s patent. In biotech, searching for keywords is not enough. You need to compare the exact sequence of your product with what existing patents claim. It is far better to find any problem before you launch than after.
Why FTO Search for Biotech Products Is Different
Most patent searches rely on keyword searches to highlight any overlapping features. However, biotechnology is very different.
If a competitor has used different terminology, a keyword search will not bring up any blocking patents. Biotech products use living material, protein structures, amino acid chains, and functional mechanisms, which require specialized analysis.
If your product uses a specific sequence, then using a keyword search will leave you completely vulnerable.
Sequence Analysis: Finding Patents That Keywords Miss
Sequence analysis is the first major part of an FTO Search for Biotech products.
In biotech, one molecule can go by many names, and a patent may cover many close versions of it. Your product could be protein, antibody, enzyme, or nucleic acid. We compare its DNA, RNA, or amino acid sequence with the sequences in patents and patent applications worldwide.
This helps identify patents not found using a keyword search. Often a patent will describe a molecule using the sequence rather than the name you know it by.
A good sequence search looks for:
- Exact matches to your full sequence
- Partial matches and fragments
- Similar sequences with a few changes
- Antibody regions, such as CDRs and framework regions
- Modified forms and variants
This is important because patent holders typically do not claim just a single sequence but rather similar sequences, functionally equivalent sequences, or a family of related molecules, so a product with small differences can still be covered by a claim.

Claim Analysis: Finding Which Patents Can Actually Stop You
Claim analysis is the second major part of an FTO Search for Biotech.
Once relevant patents have been identified, each important claim is broken into its parts. These parts will then be compared to your product, its use, and your manufacturing process. The key question is simple: does your product meet every requirement of the claim?
A careful patent claim analysis considers:
- Independent claims, which usually define the broadest protection
- Dependent claims, which add narrower but important limitations
- Claims covering the molecule itself
- Claims covering use, dosage, formulation, or manufacturing
- Claims that may apply through equivalents, not just exact wording
This step turns a long list of search results into a clear risk picture. It separates patents that truly matter from patents that merely mention similar science.

Final Thoughts
Before you sell a biotech product, you need to know if someone else already owns a patent that covers it. An FTO search for biotech answers that with two checks.
The first check compares your product’s exact makeup with the makeup described in other companies’ patents. This finds patents that look different on the surface but match what you are making.
The second check reads what each of those patents actually protects, then compares it with your product. This tells you which ones can really stop you and which ones you can ignore.
Doing both early gives you time to fix a problem, such as changing your design or asking the patent owner for permission. Doing them late leaves you very little room and a much bigger bill.
Frequently Asked Questions:
- How long does a FTO Search for Biotech take?
Most searches take around 4 to 6 weeks, depending on product complexity and the number of countries.
- Do I need an FTO search if I already have my own patent?
Yes. Owning a patent gives you the right to stop others. It does not give you the right to use your product if someone else’s patent covers part of it. - Can a startup afford one?
Scope controls cost. A focused search on your lead product and priority markets can be done at a reasonable budget, and it is far cheaper than a dispute after launch. - Is the search confidential?
We will keep your product details and findings confidential. We are happy to sign an NDA.
