What's the precise date of apixaban's patent expiration?

There isn’t a single precise expiration date for apixaban. It’s protected by multiple patent families (composition of matter, methods of use, formulations, process patents, etc.) across different jurisdictions. Each patent in each country has its own expiration date, and some dates can be affected by term adjustments or pediatric exclusivity.

If you tell me:
- the jurisdiction (e.g., United States, EU, Japan, etc.)
- whether you’re interested in the core composition-of-matter patent or another patent family (use, formulation, process)

I can look up the exact expiration dates for the relevant patents from official sources (USPTO Orange Book, EPO, etc.) and list them for you. If you’d like, I can also search now and provide the current status and patent numbers.
