Is there a Sitagliptin “biosynthesis” patent application?
The information provided doesn’t specify what “biosynthesis” refers to for sitagliptin (for example: a specific biotech manufacturing route, an engineered microorganism process, or a fermentation-based method). Without that context, it’s not possible to identify a particular sitagliptin biosynthesis patent application accurately.
If you share any of the following, I can narrow it to the right patent family and give you the application/patent details (publication numbers, applicants, filing dates, and relevant claim scope):
- the exact wording (e.g., “sitagliptin biosynthesis,” “biocatalytic,” “fermentation,” “microbial synthesis,” or “engineered strain”)
- a company name (e.g., Merck/Sitagliptin maker or a generic/biosynthesis-process applicant)
- a publication number (WO/EP/US) or a patent number
- the country/jurisdiction you care about (US, WO/PCT, EP, CN, etc.)
What search terms usually find sitagliptin biotech/biocatalyst process patents?
People often find these applications by searching for sitagliptin plus manufacturing-process terms rather than “biosynthesis” alone. Common associated terms include:
- “biocatalyst”
- “enzyme-catalyzed”
- “microbial”
- “fermentation”
- “engineered microorganism”
- “biotransformation”
- “process for preparing sitagliptin” / “method of producing sitagliptin”
If you tell me what manufacturing approach you mean, I can map it to the most likely patent keywords.
How to verify the exact patent application you mean
To confirm you’ve found the right “biosynthesis” application, look for these items in the patent record:
- the assignee/applicant (who is claiming the process)
- whether claims describe steps using organisms/enzymes (not just “green” solvents)
- whether the examples involve fermentation/biocatalysis (not only chemical synthesis)
