When can we anticipate xarelto's patent to expire?

There isn’t a single expiration date for Xarelto’s patents. Rivaroxaban (Xarelto) is protected by a portfolio of patents that cover different things (the compound itself, uses, formulations, etc.), and patent terms vary by country. Some patents may already have expired in certain markets, while others (or patent term extensions) may extend protection into the mid-2020s in others. In addition, market entry of generics can be affected by litigation settlements and regulatory exclusivity.

If you tell me the country or region you’re interested in (e.g., United States, European Union, Canada, Australia, etc.), I can look up the specific patent families and give you the current expiry dates from official sources (like the FDA Orange Book in the US or the European Patent Office). I can also point you to the exact patent numbers and their status.
