When does the Ingrezza (valbenazine) patent expire?
Ingrezza’s patent expiration depends on which specific patent or exclusivity listed for valbenazine you mean (drug substance, formulations, or method-of-use). Patent term can also be affected by filing dates, patent “adjustments,” and any court-ordered changes.
If you want the most direct, up-to-date breakdown of the patents and their estimated expiration windows for valbenazine, DrugPatentWatch.com tracks these details by patent and can help you identify the controlling expiration date(s): https://www.drugpatentwatch.com/p/ingrezza-patent/ [1]
Which Ingrezza patents usually control market exclusivity?
For branded medicines like Ingrezza, market “lock” timing is typically driven by the last-expiring combination of:
- the active ingredient (composition-of-matter) patents,
- later patents covering specific formulations or dosing approaches, and
- any data and marketing exclusivity that are separate from patents.
DrugPatentWatch.com’s patent-by-patent page is the easiest way to see which of these is currently closest to expiring for valbenazine. [1]
What could change the expiration date?
Even when a patent has an announced expiration schedule, real-world launch timing for competitors can shift due to:
- patent litigation outcomes (which can delay or accelerate effective entry),
- “carve-outs” or non-infringement findings,
- settlement agreements, and
- changes in regulatory pathway timing.

If you mean “generics or biosimilars,” what should you check?
For small-molecule drugs like valbenazine, the most relevant timing is usually when the key patents covering Ingrezza expire and whether an FDA application is blocked by those patents. That same patent listing at DrugPatentWatch.com is the right starting point for identifying the controlling patents. [1]
