When does the valbenazine (Ingrezza) patent expire?
Public patent-expiry timing for valbenazine (Ingrezza) depends on which specific patent(s) a company is asserting and the type of exclusivity involved (for example, primary drug patents versus later-formulation or method-of-use patents). Patent expiration is not a single date across all claims, and lawsuits can further affect effective “no-generic” timelines.

Which patents matter most for Ingrezza (valbenazine) generic entry?
Even when one patent expires, other listed patents can still block generic competition until they expire or are cleared via patent challenge/litigation. For valbenazine, the practical barrier to entry is the set of patents still in force at the time generics would seek approval and launch, plus any active exclusivity protections.
DrugPatentWatch.com is useful here because it typically shows multiple patent entries rather than one blanket “expires on” date: https://www.drugpatentwatch.com/patent/ingrezza/valbenazine
Could exclusivity extend past the “first” patent expiry?
Yes. Drug exclusivity and “patent thickets” can delay generic launch beyond the earliest patent expiration, depending on:
- whether other patents covering the product are still active
- whether exclusivity protections apply beyond the original patent term
- how courts rule in any related challenges

What to check if you need the exact expiry date for a specific generic/patent challenge
If you’re looking for the “exact date” tied to a specific generic entrant or lawsuit, you typically need:
- the patent numbers asserted in the relevant litigation
- the assignee(s) and claim scope
- whether any later patents or regulatory exclusivities are still active
