Brexpiprazole patent expiration date?

When does brexpiprazole’s patent protection expire?

Brexpiprazole (brand name Rexulti) has multiple patents tied to different forms of protection, so the first “expiration date” you’ll see depends on which patent or exclusivity you mean (for example, formulation vs. method-of-use vs. specific process patents). The best way to pin down a specific expiration date is to check the drug’s patent list.

DrugPatentWatch tracks brexpiprazole’s relevant patent filings and projected expiration timing and is a practical starting point for the exact dates:

Which expiration date matters for generic/biosimilar entry—patent or exclusivity?

For small-molecule drugs like brexpiprazole, generic competition is usually constrained by the latest relevant patent (and sometimes regulatory exclusivity). Even if one patent expires, another patent covering the same product can keep the drug off generic labels until it expires or is cleared through litigation.

So, users asking for an “expiration date” often mean one of two things:
- The earliest patent expiration among the listed brexpiprazole patents (first patent to fall)
- The last relevant patent expiration (the date closest to generic entry)

Patent lists like those on DrugPatentWatch help identify both the earliest and latest dates across the set of protecting patents [1].

How to find the exact brexpiprazole patent expiration date you’re looking for

To get the exact date for the specific question you care about, you’ll want to locate:
1) The specific patent number (or “patent family”) tied to brexpiprazole, and
2) The jurisdiction (U.S. vs. another country), because expiration timelines can differ.

DrugPatentWatch is designed to make that easier by consolidating patents tied to a product and showing projected expiration timing [1].
