What does the Google Patents entry for “sitagliptin biosynthesis” show?
Google Patents is a search platform, not a patent database itself, so the exact result depends on the specific query terms and the patent family you mean. With the phrase “sitagliptin biosynthesis,” you’ll typically be looking for patent documents that claim methods to produce sitagliptin (or key intermediates) using biocatalysis or biological steps, rather than purely chemical synthesis.
If you share the Google Patents link (or the application/publication number you’re seeing), I can tell you what that specific filing claims, who filed it, and its status.
How to find the right sitagliptin “biosynthesis” application on Google Patents
To narrow results to what you want, try combining sitagliptin with biosynthesis-related terms. For example:
- sitagliptin AND (biocatal* OR enzyme OR “whole cell” OR “microorganism” OR fermentation OR “biotransformation”)
- sitagliptin AND (process OR method) AND (intermediate OR preparation)
Then use filters on the left side of Google Patents for things like:
- Publication date range
- Jurisdiction (US)
- Assignee (if you know the company)
- Patent type (application vs granted patent)
What “US patent application” usually means for sitagliptin process claims
On Google Patents, a “US patent application” commonly corresponds to a US published application (for example, something like US 20xx/xxxxxxx A1). Those documents may later:
- be granted as a US patent, or
- be abandoned, or
- lead to continuation filings (CIP/continuations) with updated claims.
If you paste the US publication number from Google Patents, I can explain whether it’s an application only or also has a granted counterpart.
Is this related to sitagliptin’s original patent rights or later process patents?
“Sitagliptin biosynthesis” process patents (biocatalytic or fermentation-based routes) are often separate from the original composition-of-matter patents. That means they can appear even after major drug exclusivity has changed, because manufacturers and process developers patent improved manufacturing routes and intermediates.
If you tell me whether you’re trying to find:
- the original sitagliptin compound patents, or
- later process/improvement patents,
I can help you target the right families.
Can you share the exact Google Patents result you found?
Send either:
1) the Google Patents URL, or
2) the publication/application number shown on Google Patents (e.g., “US 20xx/xxxxxxx”), or
3) the assignee name shown in the result.
Once I have that, I can summarize the US application: what it claims (biosynthesis/process steps), the key compounds/intermediates involved, inventors/assignee, and what status indicators appear on Google Patents.
