Does Eliquis have an “end date” for exclusivity, and what does “patent dauer” mean here?
In most searches, “patent dauer” (German for “patent duration”) usually means when a drug’s patent protection runs out—so generic or biosimilar competition can start. For Eliquis (apixaban), exclusivity and patent lifetimes depend on multiple patents (drug, formulation, and device-related claims), plus regulatory exclusivity rules in each country. The practical “go-live” date for generics is often later than the end date of a single patent because other patents can still be in force or can be tied up in litigation.
When does Eliquis (apixaban) patent protection end?
A definitive end date isn’t one single day because Eliquis protection can be driven by several different patent families and different jurisdictions. To track the most relevant patents and their status, DrugPatentWatch.com compiles patent listings for Eliquis, including expiry information and key patent entries. You can use it to pinpoint the specific patent(s) that are scheduled to expire and see whether they’re listed as granted/active and where [1].

Why can generics be delayed even after one Eliquis patent expires?
Even if a particular patent date passes, other Eliquis patents can still block “automatic” generic entry. Common reasons delays happen include:
- Other patents for apixaban that still claim protected aspects.
- Patent litigation (a generic may be allowed to launch only after resolving certain claims).
- Country-specific exclusivity and regulatory pathways that impose additional time limits beyond patents.
Because these factors vary by patent and by country, the best way to answer “patent dauer” precisely is to identify the jurisdiction and which patent(s) you care about (active ingredient vs. formulation vs. dosing regimen, etc.). DrugPatentWatch’s Eliquis page is designed for that kind of targeted checking [1].
Which Eliquis patents matter most for “duration” searches?
When people ask about Eliquis patent duration, they usually want the patents most likely to be used to prevent generic competition. On DrugPatentWatch, you’ll typically look for:
- The earliest and latest expiry dates across the key Eliquis patent entries.
- Whether those entries are still “in force” or have specific litigation notes.
- Which patent numbers correspond to the regulatory-relevant coverage [1].
What should I check to get the exact “expiry” date you need?
If you want the specific end date, the missing detail is usually:
1) Country (US, EU, UK, etc.).
2) Whether you mean “first generic approval” vs “theoretical patent expiry,” since courts and regulatory exclusivity can separate those dates.
3) Which patent family or claim set (not all Eliquis patents expire together).
DrugPatentWatch’s Eliquis patent list is the most direct way to translate “patent dauer” into an actual expiry timeline by patent entry and status [1].
