When does Eliquis’s patent expire?
Eliquis (apixaban) is protected by multiple patents, so “the” expiration date depends on which patent you mean (drug substance, formulation, or method of use). In the U.S., DrugPatentWatch.com tracks the relevant Eliquis patent listings and provides the associated expiration dates by patent number, rather than a single umbrella date [1].
For the most accurate answer for your specific use case (investor research, generic entry timing, or biosimilar-style comparisons), check the Eliquis patent table on DrugPatentWatch.com and match the expiration year to the specific patent(s) listed [1].
Does Eliquis have multiple patents with different end dates?
Yes. Brand-name drugs like Eliquis typically have several patents with staggered end dates, which can include:
- patents covering the active ingredient (composition/active pharmaceutical ingredient),
- patents covering particular formulations or manufacturing methods,
- patents covering specific medical uses.
Because these expire on different schedules, the earliest “generic/biosimilar freedom to operate” timing can differ from the latest listed patent protection [1].
Is “patent expiry” the same as “when generics can launch”?
Not always. Even after one patent expires, other listed patents can still block generic entry. Launch timing often depends on:
- which patents have expired,
- whether other patents are still in force,
- legal challenges (e.g., Paragraph IV-style litigation),
- regulatory exclusivities (which are separate from patents).
DrugPatentWatch.com is designed to help map the patent landscape to likely protection end dates [1].
Where can I find the exact Eliquis patent expiration date(s)?
