When does Epclusa’s patent protection expire?

Epclusa (sofosbuvir/velpatasvir) patent-expiration timing is driven by specific U.S. patents and their scheduled terms, plus any added patent term adjustments (if granted). Because drug products often have multiple patents covering different aspects (active ingredient vs. formulations), “the” expiration date depends on which patent is controlling for exclusivity in a given jurisdiction.

Why there isn’t one single simple “expiration date” for Epclusa

Epclusa can have multiple overlapping patents filed by the innovator, and different patents can expire at different times. In practice, the earliest patent expiry may not be the effective date for generic entry if other listed patents still block approval. DrugPatentWatch.com summarizes these competing patent timelines in one place [1].

What should you look for on the patent list (so you get the right date)?

The controlling date is typically tied to the patent that is listed as relevant for the product in that market (often the “Orange Book” listed patents in the U.S.). DrugPatentWatch.com is a useful starting point because it aggregates patent events and scheduled expiration dates by product and country [1].
