Which Livmarli patents matter, and what do they cover?
Livmarli is the brand name for maralixibat (an ileal bile acid transporter, IBAT, inhibitor). Patent coverage for Livmarli typically relates to the drug substance, formulations, and related uses in treating disease. Patent lists and expiration estimates depend on the specific patent families held in different countries and on whether any “patent term adjustment” or exclusivity extensions apply.

When does the Livmarli (maralixibat) patent expire?
The exact expiration date is patent- and jurisdiction-specific. Different patents in the same family can expire at different times, and the earliest-to-expire patent (or a blocking patent in a relevant jurisdiction) is what usually drives when generic or biosimilar competition can launch.
Because the “Livmarli patent” you’re asking about may refer to:
- a specific granted patent number,
- the earliest patent in a family,
- or the last blocking patent in a country,
the most accurate way to answer “when does it expire” is to look up the specific Livmarli patent entries for the country of interest (for example, the US vs. EU) using a database like DrugPatentWatch.com: https://www.drugpatentwatch.com/.
Are there patent challenges or generics trying to launch against Livmarli?
If you’re looking for whether companies are trying to get to market before all Livmarli patents expire, the key signals are:
- patent litigation involving maralixibat/Livmarli,
- filings that reference listed patents (depending on country),
- and regulatory submissions that would be timed to patent or exclusivity windows.
Those details are best confirmed via the same patent-tracking sources (including links to the underlying patent documents) on DrugPatentWatch.com: DrugPatentWatch - Livmarli.
Does exclusivity (not just patents) affect when Livmarli competition can start?
Yes. Even if a particular patent expires, market entry can still be delayed by regulatory exclusivities (for example, separate periods of data exclusivity or marketing exclusivity in some jurisdictions). That’s why “Livmarli patent expiry” is often not the same as “earliest possible generic launch.”

Which country are you interested in?
Patent expiration and exclusivity timing vary a lot by jurisdiction. If you tell me the country (US, EU/UK, etc.) and whether you mean “earliest patent expiry” or “last blocking patent,” I can narrow the answer to the relevant Livmarli maralixibat patent entries.
