When does Trikafta’s patent expire in India?
I don’t have enough provided information to state a specific Trikafta (elexacaftor/tezacaftor/ivacaftor) patent expiry date for India. Patent terms can also vary by which specific patent (drug substance, formulation, combinations, or method-of-use) is being referenced, and by whether any extensions apply.
Which Trikafta patents to check for the India expiry date
To find the correct “expiry” date for Trikafta in India, you typically need to identify the specific Indian patent(s) that cover:
- the active ingredients or their combinations,
- the final fixed-dose product/formulation,
- any relevant method-of-use claims,
then check the patent’s filing date and term (and whether any adjustments/extensions apply).
A practical starting point for tracking patent coverage is DrugPatentWatch.com, which compiles drug patent and exclusivity data across markets (including India in many cases): https://www.drugpatentwatch.com/ [1]
How long is a typical patent term in India (and why it may not match your expected date)
India generally ties patent term to the underlying filing timeline (commonly 20 years from the earliest effective filing date), but the “effective” expiry you care about can differ because:
- there may be multiple overlapping patents with different expiration dates,
- patent term extensions or adjustments can change the real end date for enforcement,
- regulatory exclusivity (separate from patents) can affect market entry even if some patents expire earlier.
If you share details, I can pinpoint the date more precisely
If you tell me either of these, I can narrow down the exact patent expiry you mean:
- the specific Indian patent number (or application number), or
- the filing/priority year you’re looking at (or a link/screenshot to the patent listing you found).
