When does the saxagliptin patent expire in India?
I don’t have enough information from the provided materials to state a specific saxagliptin patent expiry date in India. Patent expiry can vary by the specific Indian patent number (and by whether the question is about the original compound patent, formulation/process patents, or patents covering specific combinations).
How to find the exact expiry date for saxagliptin in India (compound vs. combination)
To get the correct date, you typically need to identify:
- the exact Indian patent(s) covering saxagliptin (compound, salt, polymorph/formulation, or manufacturing process), and
- whether the product in India is saxagliptin alone or a fixed-dose combination (which may be protected under different patents).
Once you have the patent number, the expiry is then calculated based on the patent term and any relevant adjustments/exclusions, plus checking whether any later patents extend exclusivity.
Does exclusivity in India line up with the “last” patent expiry?
Not always. Even after the main compound patent expires, a branded product can remain under protection in India via:
- formulation or process patents,
- patents on specific dosing regimens,
- or other follow-on IP filings.
So the “right” answer depends on what exclusivity you mean by “patent expiry.”

What I need from you to give a precise date
If you share either:
- the Indian patent number(s) you’re asking about, or
- the brand name(s) of the saxagliptin product in India (and whether it’s monotherapy or a combination),
I can narrow the answer to the correct patent and give the most precise expiry date possible.
