When does the Entresto patent expire in Canada?
Entresto (sacubitril/valsartan) is protected in Canada through a mix of patent rights and regulatory exclusivity. Exact “patent expiry” dates depend on which specific patent(s) cover the product, since some patents expire earlier than others and some may be tied to particular formulations, dosing forms, or combinations.

What patents cover Entresto in Canada (and why there isn’t one single date)?
Users often search for a single expiry date, but branded drugs like Entresto typically have multiple Canadian patents listed against the medicine. Different patents can cover different aspects, such as:
- the active ingredient combination,
- specific pharmaceutical formulations or dosing forms,
- manufacturing processes, or
- other technical claims.
Because of that, Canada-related protection usually means “the last relevant patent/exclusivity you have to get past,” not one universal date.
Can a generic or biosimilar enter Canada before the last patent expires?
In Canada, generic entry is generally tied to whether the developer can lawfully market the product without infringing the relevant patents and whether the required regulatory steps are satisfied. Even if one patent expires, other still-in-force patents can block full market entry of a generic product until they expire or are otherwise resolved.
Are there patent challenges or court cases affecting timing?
Even when expiry dates are known, real-world launch timing can change if patents are challenged through legal or regulatory processes. Those disputes can delay entry even after some patents expire.
