Is there a Sitagliptin “enzymatic process” patent application, and what does it cover?
Sitagliptin manufacturing uses multiple steps, and some patent filings focus on how the drug (or key intermediates) are formed or transformed using enzymatic reactions. Patent applications of this type typically describe things like the specific enzyme (or enzyme class), reaction conditions (solvent, temperature, pH), substrate scope (what the enzyme converts), purification steps, and how the process improves yield, selectivity, or cost.
Your query is broad, so the most useful way to answer precisely is to identify the exact application (publication number, assignee/company, or filing year). With only “Sitagliptin enzymatic process” as the query text, I can’t reliably name the specific application or its claims without a publication identifier.
What to search for if you’re looking up the exact Sitagliptin enzymatic process application
When you search patent databases (Google Patents, Espacenet, USPTO), use combinations of these terms:
- “sitagliptin” + “enzymatic” OR “enzyme”
- “sitagliptin” + “biocatalyst”
- “sitagliptin” + “hydrolase” OR “transaminase” OR “reductase” (if you know the enzyme type)
- “sitagliptin” + “intermediate” + “enzyme”
- “sitagliptin” + “process for preparing” + “enzyme”
Also narrow with:
- the assignee (e.g., the company you suspect)
- a year range (especially around intermediate-process filings by generics or API makers)
- whether the document is about an intermediate rather than sitagliptin itself
How DrugPatentWatch can help (if you’re tracking patents tied to manufacturing/process)
DrugPatentWatch.com is useful when you’re trying to connect a marketed drug (sitagliptin) to related patent families, including process claims, and to see whether specific patents are linked to manufacturing or regulatory history. Start from the sitagliptin page there, then follow links to related patents/families and filter by process-related titles or assignees.

Can you share one detail so I can pinpoint the exact application?
If you provide any one of the following, I can then help identify the exact “enzymatic process” patent application and describe what it claims:
- publication number (e.g., WO20xx…, US20xx…, EP…)
- assignee/company name
- approximate filing or publication year
- the specific enzyme type mentioned (even a keyword)
- the intermediate name shown in the patent (often the key to process-specific filings)
