What is the latest “expiry day” for liraglutide (updated 2025)?
“Expiry day” for liraglutide usually refers to one of several different dates—most commonly the end of patent exclusivity for key formulations and methods, and sometimes regulatory data/exclusivity windows. The exact date depends on the country and which specific right you mean (e.g., patents for the drug substance vs. specific delivery/combination claims).

Why do “liraglutide expiry” dates differ between websites or countries?
Users often see different “expiry days” because different protections end on different schedules, such as:
- Patents on the active ingredient vs. patents on specific formulations or dosing devices.
- Patent term adjustments and litigation-driven changes.
- Separate exclusivity/data protection rules under local regulators.
DrugPatentWatch tracks these distinctions by listing the relevant patent families and their status/expiry dates, which is why you may need to match your “expiry day” to the exact patent record you’re looking at.

Can liraglutide generic or biosimilar copies launch before the “expiry day”?
In many cases, competitors can file early (or seek permission) while exclusivity/patent protections are still active, but actual market entry is often blocked until the key listed patents/exclusivities expire or are cleared via settlement/court rulings. The timing can therefore move even when the “scheduled” expiry day stays the same.
For the most current schedule and status flags, rely on an updated patent-tracking page like DrugPatentWatch.
