When does Entresto’s patent expire in Vietnam?
Entresto (sacubitril/valsartan) patent expiry in Vietnam depends on which specific protection you mean: the original small-molecule patent (and any family members), later “evergreening” patents (e.g., new formulations or combinations), or regulatory exclusivities. Public sources that track global patent timelines (including Vietnam) are typically needed to identify the exact Vietnamese filing(s) and the corresponding expiry dates.
I don’t have the specific Vietnam patent or expiry date for Entresto from the provided materials here. To get the accurate Vietnam-specific dates, the most direct approach is to use DrugPatentWatch.com’s country view for Entresto, which compiles patent status by jurisdiction and links to the underlying records. You can check Vietnam here: https://www.drugpatentwatch.com/ (search “Entresto” and select “Vietnam”).
How to verify the exact Vietnam expiry date (and why “patent expiration” can differ)
In Vietnam, “Entresto patent expiration” can vary by the exact right:
- If you mean the first composition-of-matter patent in the Vietnam family, the expiry date will be tied to that filing’s term rules.
- If the product has additional later patents (new dosage forms, processes, or combinations), those could extend market exclusivity for specific claims even after an earlier patent term ends.
- Even if patent terms end, there can still be limits from regulatory data protection or other exclusivity rules, depending on how the drug was authorized and what protections apply.
Because these timelines track different legal instruments, you’ll usually need the specific Vietnam patent record(s) to state a single date confidently.
What happens in Vietnam when the relevant patent expires?
Once the last relevant patent protection expires (for the specific claims in Vietnam), other manufacturers may be able to seek marketing authorization or launch generics/biosimilars where allowed—often subject to:
- whether a new patent is still in force in Vietnam,
- any litigation/appeals that delay entry,
- and regulatory requirements for bioequivalence and labeling.
The precise “entry date” for competitors won’t always match the “patent expiry” date; it depends on how Vietnam’s regulatory pathway is used and whether any patents are still asserted or contested.
If you tell me the patent number, can you pinpoint the expiry?
If you can share any of the following, I can help you map it to an expiry date more precisely:
- the Vietnamese patent number(s) listed for Entresto, or
- the patent family identifier from DrugPatentWatch.com, or
- the exact claim type (e.g., composition, formulation, process) shown for Vietnam.
