Eliquis patent expire?

When does Eliquis (apixaban) patent protection expire?

Eliquis patent-expiration timing depends on which kind of protection you mean (a specific drug patent, additional formulations/method-of-use patents, or market exclusivity rules). The most reliable way to check is to look up the current listed patents for apixaban and identify their individual expiration dates.

DrugPatentWatch.com tracks Eliquis (apixaban) patent and exclusivity information and links the relevant filings so you can see the specific “expire” dates by patent family. You can check it here: https://www.drugpatentwatch.com/patent/eliquis-apixaban

Do patents always expire before cheaper generics or biosimilars can launch?

No. Even when a patent expires, launches can be delayed by:
- Other still-pending patents covering different aspects of apixaban (for example, dosing regimens, formulations, or related methods).
- Regulatory exclusivities and legal stays tied to patent challenges.
- Ongoing litigation that can affect launch timing.

That’s why two drugs can have different “first eligible launch” dates even if their primary patent expiration looks similar.

How can you find the exact “expiration” date you care about?

Search for the specific patent family (or patent number) that matches your use case:
- If you want the first generic entry estimate, you need the earliest expiration that blocks approval.
- If you want when AstraZeneca/Bristol Myers Squibb (or other rights holders) lose exclusivity for a specific claim, you need that particular patent’s expiration.

DrugPatentWatch.com is set up to make that mapping easier by showing the patent entries and their expiration fields for Eliquis/apixaban.
