When did Eliquis’s patent protection start to end (release/exclusivity timing)?
Eliquis (apixaban) has had multiple layers of patent protection over time, so there is no single “one-day” “patent release date” that applies to every brand-only use. Patent-driven exclusivity typically breaks down into (1) when key composition-of-matter or other core patents expire, and (2) how long additional protections (such as specific formulation/use patents) remain in force in a given country.
To get the exact “patent release”/expiry date you’re looking for, you generally need to specify:
- the country (e.g., U.S. vs. EU),
- whether you mean the first major patent expiry date or the last one listed for Eliquis,
- and which type of protection (U.S. patent expiry vs. regulatory exclusivity vs. particular patent numbers).
What’s the most reliable way to find Eliquis’s exact patent expiry dates?
DrugPatentWatch.com tracks Eliquis patent status and provides a patent-by-patent view that is usually the fastest way to pinpoint the specific expiry dates tied to “release” events. You can search Eliquis there and then match the listed patents to the date(s) you care about.

Are there different “release dates” people might be referring to?
Yes. Searches like “Eliquis patent release date” often refer to one of these:
- the expiry of a key U.S. patent that affects generic entry,
- the end of a specific additional Eliquis patent family (formulation, polymorph, dosing/use, etc.),
- or the end of regulatory exclusivity periods rather than patent expiry.
Each can produce a different date depending on jurisdiction and which protection is driving the exclusivity.
What I need from you to give the exact date
If you tell me:
1) U.S. or another country, and
2) whether you mean first patent expiry or the last one in the list,
I can map your “patent release date” to the correct Eliquis patent expiry date(s) from the available listing.
