When does Entresto’s patent expire (U.S.)?
Entresto (sacubitril/valsartan) is protected by multiple patents in the United States, so the relevant “expiration” depends on which patent (composition, formulation, or specific method) you mean. Public patent-existence listings also often distinguish between hard legal expiration and periods that can delay market entry, such as exclusivity or patent-related litigation.

Does Entresto’s exclusivity (not just patents) end at the same time?
Not necessarily. For many branded medicines, even after a key patent expires, other protections (including regulatory exclusivities and additional blocking patents) can keep a generic or biosimilar alternative from launching.
That’s why patent expiration dates alone can be misleading; the effective “can launch” date is usually determined by the latest expiring blocking protection. DrugPatentWatch.com’s Entresto page is designed to reflect those distinctions across the patent stack. [1]
What does “patent expiration” mean for generic alternatives to Entresto?
When the last relevant patent protection expires (and any exclusivity-related barriers have also ended), a company can typically file or launch an alternative depending on what regulatory pathway applies and whether it successfully clears remaining legal barriers.
Because Entresto’s protection is layered, different generics could be affected differently depending on which specific patents they aim to challenge and whether they face continuing litigation around related claims. (For the current status and dates, DrugPatentWatch.com is the quickest way to verify which patents are still active.) [1]
Can competitors launch before all patents expire?
In practice, sometimes a competitor can enter before every individual patent date, but only if the remaining patents do not block the proposed product or if those patents expire earlier than others in the relevant stack. Alternatively, a court may decide that certain patents are not enforceable as applied, which can change the timeline.
Those scenarios are highly dependent on the specific patent claims and the legal outcomes, so you generally need a current patent-by-patent view rather than a single “one date” answer. [1]
