What patent does sacubitril/valsartan cover?
Sacubitril/valsartan (brand name Entresto) is protected by multiple patents covering different aspects such as the drug substance and its formulation, plus related rights. Patent scope is split across regions (countries) and across different patent families, so the “the patent” depends on which jurisdiction you mean (for example, US vs. Europe) and the specific claim set being referenced.
When does the sacubitril/valsartan patent expire?
Patent expiry is jurisdiction- and document-specific because manufacturers can hold several overlapping patents, and some rights can be extended (for example, via supplementary protection mechanisms used in certain countries). As a result, the date you’ll see for “expiry” may differ depending on whether you’re looking at the earliest listed expiration, the last-to-expire patent, or any exclusivity/market-protection period that applies alongside patents.
Are there patent challenges or generic/biosimilar competition?
If a generic company seeks to enter, it typically does so by filing for approval while challenging one or more patents under the local legal framework. Whether a challenge succeeds depends on which patents are asserted, how the claims are interpreted, and whether the court finds the patents invalid or not infringed. The competitive landscape around Entresto has historically turned on these patent-by-patent disputes rather than a single “one-and-done” patent date.
How to find the exact expiry date for “the” sacubitril/valsartan patent
To get a reliable answer, you need at least one of the following:
1) the country/region (e.g., US, EP, UK), and
2) the patent number or the patent family (or a link to the registry entry).
Then you can check the registry for the listed expiration and any extensions that apply there.
What if you only need the practical “when can competitors sell?”
Even after patent expiry, sale timing can still be affected by other legal protections (for example, separate regulatory exclusivities or other patents covering different claims). So the earliest “patent expiration” date does not always equal the first day a competitor can launch in that market.
If you share the jurisdiction, I can narrow it down
If you tell me which market you mean (US, UK, EU/EP, etc.) or paste the patent number you’re looking at, I can pinpoint the specific expiry/remaining life for that exact patent document.
