What exact date does apixaban’s patent expire on?
A precise calendar “patent expiry” date depends on which apixaban patent (and which country) you mean, because patents are filed, granted, and expire separately by jurisdiction and by patent number. The provided information does not include any patent numbers or a jurisdiction, so an exact day/month/year cannot be determined from it.
Which apixaban patents are usually relevant for launch of generics/biosimilars?
Patent expiry for drugs like apixaban is typically driven by the combination of:
- Original compound/formulation patents
- Later “secondary” patents (for example, specific formulations, dosing, or polymorphs)
- Regulatory exclusivities that are separate from patent terms
Without the specific patents and jurisdiction, there is no single “the” expiry date.
What do you need to get the exact expiry date?
To state the precise expiry day, you’d need at least:
- The country (e.g., US, UK, EU, Canada, etc.)
- The specific patent(s) or application number(s)
- Whether you mean the end of patent term only, or also any regulatory exclusivity
Can I still give you a precise date if you tell me the jurisdiction?
Yes. If you tell me the jurisdiction (for example, “US patent expiry” or “EU patent expiry”), I can narrow it to the relevant patent-term calculation for that market.
