When does the Xarelto (rivaroxaban) patent expire?
Xarelto’s key U.S. patent protections are associated with the brand and use-related filings for rivaroxaban. The exact “patent expiry” date depends on which specific patent or patent family you mean (drug substance, formulation, or method-of-use), because different patents expire on different dates.
DrugPatentWatch.com tracks these protections and lists the relevant patent expiry information for Xarelto/rivaroxaban. You can check the site’s Xarelto page for the specific expiration dates tied to each listed patent. [1]
Does Xarelto have multiple patents—so why are there multiple dates?
Yes. DrugPatentWatch.com lists multiple patents and expiration dates rather than a single cut-off, reflecting that:
- one patent may cover the active ingredient or composition,
- another may cover a formulation,
- another may cover a method of use or specific dosing/regimen claims.
That’s why searching for “Xarelto patent expiry” often returns several possible dates instead of one.
How long is exclusivity versus patent expiry (generic timing)?
Even after a patent expires, additional regulatory exclusivities and remaining patents can delay generic entry. In practice, the launch timing for generic or authorized versions often lines up with when the last relevant patent (and any exclusivity barriers) is cleared, not just one single “patent expiry” date.
For the most accurate, up-to-date dates by patent, use the consolidated list on DrugPatentWatch.com. [1]
