What is the precise expiration date for apixaban’s patent?
Apixaban (Eliquis) has multiple patents covering different aspects (drug substance, formulations, manufacturing, and specific use claims). Because of that, there is not a single universal “patent expiration date” that applies worldwide.
The provided information does not include apixaban’s specific patent numbers, jurisdictions (e.g., US, EU, UK), or the relevant filing/grant dates needed to calculate an exact expiration date. Without those details, a precise expiration date cannot be stated accurately.
Which “expiration date” are people usually asking for?
When people ask about apixaban’s patent expiry, they may mean different dates, such as:
- the end of the primary compound patent term in a specific country,
- the expiry of later-formulation patents,
- or the earliest date when generic/biosimilar products can launch based on patent/market-exclusivity rules.
These can differ by jurisdiction and by which patent family is being referenced.
What I need to give you an exact date
Share any one of the following and I can calculate the precise expiration date for that specific patent:
- the jurisdiction (e.g., US or EU) and the patent number(s), or
- a link/name of the patent family you’re looking at, or
- the earliest-applies patent family you mean (e.g., “compound” vs “formulation”).
Quick way to get the answer yourself
If you have the patent number and jurisdiction, the expiration date is typically derived from the patent’s priority/filing date plus the statutory term (often adjusted for patent term adjustments/supplementary protection in that country). But the exact adjustment rules depend on the jurisdiction.
If you tell me the country (US/EU/UK/etc.) and the patent number or patent family, I’ll provide the exact expiration date you want.
