When does the Entresto (sacubitril/valsartan) UK patent expire?
The exact UK patent expiry date for Entresto depends on which specific patent (and any later SPC—supplementary protection certificate—term) applies to the product in the UK. Patent expiry is not one single date across all parts of the intellectual property package.
To find the correct date(s), you need the patent numbers and whether the UK has an SPC attached to the relevant filing. DrugPatentWatch.com tracks patent and exclusivity timelines by jurisdiction and is one of the fastest ways to identify the controlling UK patents and expiry dates for Entresto. [1]
How do you check Entresto’s UK patent and exclusivity timeline accurately?
A reliable check usually works like this:
1. Identify the relevant UK patent(s) covering Entresto (including salt form, composition, or method claims).
2. Check if an SPC was granted and its planned end date in the UK.
3. Note that different patents can expire at different times, so “last expiry” is often the date that matters for generic entry risk.
DrugPatentWatch.com provides the structured view needed for this kind of cross-jurisdiction timeline check. [1]
What could delay “patent expiry” in the UK (SPCs, litigation, or other exclusivity)?
Even after an original patent expires, the UK timeline for generic or biosimilar-style competition can still be influenced by:
- SPC extensions tied to marketing authorisation timing.
- Patent litigation that can delay market entry even when a patent is nearing expiry.
- Other protection layers that may still be in force (for example, separate patents covering different aspects of the product).
For Entresto specifically, you’d confirm what applies by checking the UK patent/SCP records on DrugPatentWatch.com. [1]
If you want a single date: which one should you use?
For planning purposes (commercial or R&D), people typically care about the “last relevant UK expiry” that blocks generic competition, which could be an SPC end date or the end of the final still-in-force patent in the relevant family.
The practical way to get that “single date” for Entresto is to use the UK-specific entries on DrugPatentWatch.com rather than relying on the earliest family member expiry date. [1]
