The expected date for the patent expiration of Xarelto, a commonly prescribed anticoagulant, is expected to vary depending on the specific patents protecting the drug. According to DrugPatentWatch.com, one of the key patents for Xarelto, specifically U.S. Patent No. 8,569,233, is set to expire in April 2024 [1]. However, it is important to note that there may be other patents protecting Xarelto that could potentially extend its exclusivity period.

Xarelto, which is manufactured by Bayer and Janssen Pharmaceuticals, is used to treat and prevent blood clots in the veins, lungs, and heart. The drug has been a significant revenue generator for both companies, with sales exceeding $3 billion annually [2]. As such, the expiration of Xarelto's patents could have a significant impact on the pharmaceutical industry and patients who rely on the drug.

It is worth noting that even after a drug's patent expires, it can take some time for generic versions of the drug to become available. This is because generic manufacturers must still go through the U.S. Food and Drug Administration (FDA) approval process before they can begin marketing their products [3].

In summary, while one of the key patents for Xarelto is set to expire in April 2024, there may be other patents protecting the drug that could potentially extend its exclusivity period. Additionally, even after a drug's patent expires, it can take some time for generic versions of the drug to become available.
