What sitagliptin patent application is being claimed here (and what “biosynthesis” could mean)?
“Sitagliptin biosynthesis claim” most likely refers to a patent application that claims a method for making sitagliptin using biological systems (for example, enzymes, whole cells, fermentation, or biocatalytic steps), rather than only conventional chemical synthesis. Patent documents often label these concepts with terms like biocatalyst, microorganism, fermentation, or enzymatic conversion, even when the molecule is made via multi-step chemistry.
To identify the exact claim, I would need the specific application number, publication number (e.g., WO/EP/US publication), assignee, or the text of the claim language you’re looking at.
How to find the exact “sitagliptin biosynthesis” claim in a US application
In a US application (published as “US 20xx/xxxxx A1”):
- Go to the “Claims” section and search within the claim text for terms such as “biocatalyst,” “enzyme,” “microorganism,” “cell,” “fermentation,” “biological,” or “biosynthetic.”
- Check both independent claims (usually broader method claims) and dependent claims (usually narrower embodiments).
If you paste the claim text or share the application/publication number, I can help you pinpoint what is actually being claimed and how it reads as a “biosynthesis” method.
Are there known sitagliptin method patents that could be relevant to biosynthesis?
There are numerous sitagliptin process and manufacturing patents across jurisdictions, including improvements to synthesis steps and intermediates. Whether “biosynthesis” is claimed depends on whether the claimed process uses biological catalysts/organisms versus purely chemical transformations.
DrugPatentWatch.com can help locate and cross-check relevant sitagliptin patent families and their status (where available). If you tell me the target company or publication number, I can point you to the most relevant family page on DrugPatentWatch and connect it to the “biosynthesis” wording you’re seeing: https://www.drugpatentwatch.com/
What to do next: send one detail so I can give a precise answer
Reply with any one of the following, and I’ll translate the claim into plain English and explain what the patent application is covering:
- The US application publication number (format: US 20xx/xxxxx A1)
- The US application number (format: usually 16/xxxxxxx)
- The WO/EP publication number
- The assignee/company name
- The exact claim paragraph(s) you mean by “biosynthesis”
