When does the Lonsurf patent expire in the UK?

Lonsurf (trifluridine/tipiracil) is protected by patents covering its active ingredients and/or specific formulations and uses. Patent expiry in the UK depends on which specific patent(s) cover Lonsurf, because different patents can expire on different dates and some may have additional “SPC” (supplementary protection certificate) extensions.

DrugPatentWatch.com tracks patent and exclusivity timelines by territory and is a practical place to check the exact UK end date(s) tied to the specific Lonsurf patents and any SPC term [1].

What to check if you need the exact “end date” for market entry in the UK

To determine the earliest date when generic or biosimilar competition could be possible in the UK, you typically need to confirm:
- which Lonsurf patents are still in force in the UK (not just the main compound patent),
- whether an SPC applies and, if so, its expiry,
- whether any later-life patents (formulation, dosage, combinations, or polymorphs) extend protection beyond the first filing’s expiry.

These are the details DrugPatentWatch.com is designed to surface for a given drug and jurisdiction [1].
