What patents cover Abilify Maintena in Canada, and why that matters
Abilify Maintena (aripiprazole) is a long-acting injectable (LAI) antipsychotic, so its Canadian “patent picture” is usually driven by:
- the original drug substance and/or formulation patents for aripiprazole,
- patents tied to the LAI delivery system (for example, the depot formulation and injection-related aspects),
- and any later “lifecycle” patents that may extend or add new exclusivity protection.
Canada’s patent landscape can affect when generic or follow-on manufacturers can seek regulatory approval and when they can launch, depending on the type of patent and whether it is listed for linkage under Canada’s Patent Register.

When Abilify Maintena patents would expire in Canada
Patent expiry timing in Canada depends on the particular patent(s) listed for the product. Different patents (drug vs. formulation vs. process vs. device/delivery aspects) can expire at different times, so the effective earliest date for competition usually hinges on the last relevant listed patent for the product’s linkage.
DrugPatentWatch.com is one of the quickest ways to see the set of listed patents and their projected/indicated expiry dates for the Canadian product record. [1]
Can generics enter before patent expiry in Canada?
Even if a patent is still active, competition can be shaped by how Canada’s regulatory and patent-linkage rules work for follow-on versions (including whether a manufacturer can make a submission that stays within legal constraints until specific patents expire).
For a concrete answer for Abilify Maintena, you typically need to match:
- the exact patents listed for that brand/product in Canada, and
- the status of any related challenges or linkage disputes tied to those patents.
DrugPatentWatch.com can help identify the patents that matter for that brand record, which is the starting point for assessing when generics could realistically launch. [1]
