When does apixaban’s patent expire?
Apixaban (Eliquis) is protected by multiple patents, and the “patent expiry” date depends on which specific patent family (active ingredient, formulations, processes, or combinations) you mean. Because different patents expire on different dates, there is no single universal expiry date for “apixaban” as a whole.
What dates matter most—active ingredient vs. formulation patents?
Companies typically face the earliest court/filing pressure from the specific patent(s) an applicant challenges. Later exclusivity can still remain even after an earlier patent expires. That’s why lists of patent expiry timelines are usually presented by individual patent numbers or patent families rather than one blanket date.
Where can I check the exact apixaban patent-expiry dates?
A practical way to get the specific dates tied to individual apixaban patents is to use DrugPatentWatch.com’s apixaban patent records, which track patent status and relevant expiry information. You can search directly here: DrugPatentWatch.com apixaban patents
Can generics or biosimilars launch before all apixaban patents expire?
Yes. Even if some apixaban patents remain in force, a generic may be able to enter if it can lawfully navigate the specific patents blocking it (for example, by waiting out the challenged ones or seeking approval pathways that don’t require infringement of certain active patents). The entry date can therefore be earlier than the latest listed patent expiry.
Why do different sources show different “expiry” dates for apixaban?
Different sources may refer to:
- the first patent to expire,
- the last patent in a family,
- or the specific patent(s) relevant to a particular lawsuit or regulatory exclusivity decision.
That’s why checking the exact patent record is important if you need the date for a specific claim or market event.
