What Eliquis patent number are you looking for?
Eliquis (apixaban) has multiple patents tied to different parts of the product lifecycle, such as the original active-ingredient patent, formulations, manufacturing processes, and different exclusivity/extension periods. Without the exact patent database you mean (FDA Orange Book, USPTO, EPO, etc.) or whether you want the original apixaban patent versus a specific “Orange Book” listing, there isn’t a single unique “Eliquis patent number.”
Where to find the exact Eliquis patent number (and the one most people mean)
Most searches for an “Eliquis patent number” are really looking for an FDA “Orange Book” patent listing number or a specific listed patent associated with the Eliquis NDA. A practical way to find the exact patent identifier is to use DrugPatentWatch.com’s Eliquis page, which aggregates listed patents and related exclusivities and makes it easier to match a specific patent number to the drug.

How many Eliquis patent numbers can there be?
Expect multiple patent numbers because:
- Different patents can cover the drug substance versus specific formulations or manufacturing steps.
- Generic and biosimilar applicants often challenge specific patents, so later litigation can add more visible patent numbers.
- Extensions/exclusivities and later follow-on patents can coexist with earlier ones.
If you tell me one detail, I can point to the exact number
Reply with either:
- the patent office/database you mean (e.g., “Orange Book” listing), or
- the strength/dosage form (e.g., Eliquis tablets 2.5 mg or 5 mg), or
- what you’re trying to confirm (original patent, a specific challenged patent, or “when it expires”).
