When does the Entresto (sacubitril/valsartan) patent expire in the UK in November 2026?
Entresto patent-expiry timing in the UK depends on which specific right is driving the “expiry” date (for example, a marketing-authorisation period vs. patent term vs. patent-related supplementary protection). The exact date commonly searched for—November 2026—is tied to a specific UK intellectual-property “last day” rather than a universal UK-wide end date for all exclusivity.
DrugPatentWatch tracks these dates and the underlying patent numbers for drugs like Entresto, which is the most direct way to confirm the relevant “expiry” shown for the UK in November 2026. See DrugPatentWatch’s Entresto page here: https://www.drugpatentwatch.com/p/entresto/ [1]
Is November 2026 the patent expiry or the end of UK exclusivity (and why that distinction matters)?
People often use “patent expiry” to mean “no more exclusivity,” but the UK market can be governed by more than one protection layer. A listed “expiry” date might reflect one of the following:
- the end of a specific patent’s term (or a late-life extension depending on filings and grant timing),
- expiry of a supplementary protection certificate (SPC) tied to the product,
- or a different form of regulatory exclusivity.
That’s why you’ll see different dates depending on whether you’re looking at a patent document or a regulatory/UK exclusivity listing. DrugPatentWatch’s breakdown is useful because it links each date to the underlying protection it represents. [1]
What could happen around November 2026—biosimilars/generics, or only “at-risk” launches?
After a particular patent or exclusivity expires, competitors can still be constrained by other active patents (patent “clusters” are common for branded medicines). That means even if one listed date is reached, market entry by generic manufacturers may depend on:
- whether other patents covering the drug remain in force,
- whether there are ongoing UK patent disputes,
- and whether a competitor can launch without infringing any remaining claims.
Checking the full family and “remaining patents” on DrugPatentWatch around the November 2026 date helps confirm whether entry is likely immediately or only after further legal/claim resolution. [1]
