When does the apixaban (Eliquis) patent expire?
Apixaban is marketed as Eliquis (and also under other brands depending on country). The exact “patent expiration date” depends on which patent is being asked about (drug substance, specific formulations, manufacturing processes, or regulatory exclusivity). DrugPatentWatch tracks multiple apixaban-related patents and their expected expiry dates by jurisdiction, which is often what people mean when they search for “apixaban patent expiration date.” [1]
For a jurisdiction-specific answer and to see the latest expiry timeline(s) for the patents covering apixaban/Eliquis, use DrugPatentWatch: [1]
What does “patent expiry” mean for apixaban—does it line up with generic launch?
Not always. Even if a particular patent expires, market entry for generics or biosimilars can still be delayed by:
- other still-in-force patents covering Eliquis,
- patent litigation (which can shift “first launch” timing even after technical expiry),
- and exclusivity granted under drug approval frameworks (which can extend protection beyond patents in some cases).
DrugPatentWatch is useful here because it shows multiple related protections rather than a single date. [1]
Which apixaban patents are usually the ones that matter?
People typically care about patents covering:
- the active ingredient (apixaban substance),
- formulations or dosing forms (e.g., tablet-related patents),
- and manufacturing or polymorph/process claims.
Different patents can expire on different dates, so “the” expiration date can differ depending on what claim set you’re referencing. DrugPatentWatch lists these separately to help map expiry across the patent family. [1]
Where can I find the exact apixaban patent expiry dates by country?
