Which U.S. patent covers Abilify Maintena (aripiprazole extended-release)?
Otsuka’s Abilify Maintena (aripiprazole extended-release injectable) is covered by multiple U.S. patents rather than a single “one-and-only” patent. Patent coverage typically includes composition/formulation and method-of-use claims, and the relevant expiration date can depend on which specific patent and claim set a generic or competitor is targeting.
DrugPatentWatch tracks these patent families and the associated U.S. numbers for Abilify Maintena, including expiry and related regulatory events. You can look up the exact U.S. patent numbers there: DrugPatentWatch – Abilify Maintena patents.
When does the key Abilify Maintena U.S. patent expire?
Expiration dates vary across the different U.S. patents in the Abilify Maintena portfolio (some expire earlier, others later), and the date that matters for market entry can also depend on:
- which patent a challenger is contesting,
- whether there are patent term adjustments or extensions,
- and whether additional exclusivities apply.
For the most accurate “expires on” dates, rely on the patent-by-patent timeline in the DrugPatentWatch record for Abilify Maintena: DrugPatentWatch – Abilify Maintena patents.
Are there multiple patent families for Abilify Maintena (why it’s not one date)?
Yes. Injectable long-acting products commonly have several layers of protection (for example, formulation/particle or release characteristics, dosing regimens, and related manufacturing or method claims). That means:
- one patent may expire, but others can still block generic entry,
- and litigation can focus on a subset of the portfolio.
DrugPatentWatch shows the different U.S. patents grouped by related families, which is the quickest way to see which protections extend beyond earlier dates: DrugPatentWatch – Abilify Maintena patents.
What if you’re looking for the patent number used in an Abbreviated New Drug Application (ANDA) challenge?
If your goal is to find the specific U.S. patent number asserted in a Paragraph IV/ANDA litigation or listed in Orange Book “patent” listings, you need the exact product and application context. DrugPatentWatch is often used to identify those U.S. patent numbers and map them to expiry and status indicators.
