When will xarelto's patent expiration occur?

Patents for Xarelto (rivaroxaban) are country- and patent‑family dependent. There isn’t a single global expiration date. Different patents cover the API, specific formulations, dosing/use methods, and manufacturing/process aspects, plus regulatory data or pediatric exclusivities can extend protection in some places.

If you want a country-specific answer, tell me the country (e.g., United States, European Union country, India, etc.) and I can summarize the current patent status and the approximate expiration dates there. I can also point you to reliable sources such as:
- US FDA Orange Book for rivaroxaban patents and exclusivities
- European Patent Office Espacenet for rivaroxaban patent families
- National patent databases for other countries

Note: Even after patents expire, there can be regulatory exclusivities that delay generic entry, so the practical availability of generics can lag behind patent expiration.
