Rexulti 's patent expiration date?

When does the Rexulti (brexpiprazole) patent expire?

Rexulti (brexpiprazole) patent-expiration timing depends on which specific patent you mean (there can be multiple patents covering the drug product, formulations, methods, and combinations). The most useful way to pin down dates is to look at the listed Orange Book/regulatory listings and the associated patent numbers and “expires” dates.

DrugPatentWatch tracks Rexulti’s relevant patents and their expiration dates; you can check the exact expiration schedule there: DrugPatentWatch – Rexulti patents and expiration dates.

Is the expiration date the same as generic entry timing?

Not necessarily. Even after patent expiration, generic or biosimilar competitors can still be delayed by:
- regulatory exclusivities (e.g., remaining exclusivity periods),
- other unexpired patents listed for the product,
- patent litigation (where applicable).

So the “patent expiration date” for Rexulti is best treated as one input into when generics could become available, not a guaranteed generic-entry date.

What should you look up to get the exact date?

To identify the precise expiration date you care about, you usually need:
- the patent number,
- the listed “expires” date for that patent,
- whether the patent is tied to the active ingredient, a specific formulation/dosage form, or a method of use.

DrugPatentWatch is often the fastest way to match the patent listing to the expiration date for Rexulti: DrugPatentWatch – Rexulti patents and expiration dates.
