Is maralixibat off patent in India?
You would need the specific Indian patent numbers and their status to say whether maralixibat is “off patent” in India. Patent expiry depends on the filing/priority dates and which patents (drug substance, formulation, salts, dosing regimen, etc.) protect maralixibat in that country. Without those details, it’s not possible to confirm whether all relevant patents have expired in India.
How to check whether maralixibat’s patents have expired in India
In India, you can verify status by looking up maralixibat-related patents in the Indian Patent Office/online patent records, then checking:
- whether each patent has reached its maximum term (typically 20 years from the earliest priority date, subject to adjustments)
- whether any patent is still in force due to priority timing or term adjustments
- whether any additional patents (“evergreening” such as new formulations, polymorphs, or methods of use) are still active
Can generic maralixibat launch in India if one patent expires?
Even if one patent expires, another active patent can still block a generic launch or limit what a generic can claim (for example, a different formulation or method of use). Generic availability can also depend on regulatory and market factors (drug approval, manufacturing, and any patent-linked litigation).
What else could affect “off patent” beyond expiry dates?
If there has been patent litigation or patent linkage practices, outcomes can delay generic entry even after expiry. Also, exclusivity-like protections (if any apply) can affect timelines independently of patent expiry.
If you share details, I can help you determine the likely status
If you provide either:
- the manufacturer/brand name in India, or
- one or more Indian patent numbers covering maralixibat,
I can help map those to expected expiry timing and explain whether they appear to be still active.
