When Will Xarelto Patent Expire? A Comprehensive Guide

Xarelto, a popular anticoagulant medication, has been a game-changer in the treatment of atrial fibrillation and deep vein thrombosis. However, with the patent expiration date looming, pharmaceutical companies and patients alike are wondering what the future holds for this medication. In this article, we'll delve into the world of patent law and explore when Xarelto's patent will expire.

What is Xarelto?

Xarelto, also known as rivaroxaban, is a direct oral anticoagulant (DOAC) developed by Johnson & Johnson and Bayer. It was approved by the FDA in 2011 for the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation. Since then, Xarelto has become a widely prescribed medication for various indications, including deep vein thrombosis and pulmonary embolism.

Patent Law Basics

Before we dive into the specifics of Xarelto's patent, let's quickly review the basics of patent law. A patent is a legal right granted to an inventor or assignee for a limited period, typically 20 years from the date of filing. During this time, the patent holder has exclusive rights to manufacture, use, and sell the invention. After the patent expires, the invention becomes public domain, and anyone can use it without infringing on the patent holder's rights.

Xarelto's Patent Status

According to DrugPatentWatch.com, Xarelto's original patent, US Patent 7,598,244, expired on July 28, 2020. However, Xarelto's patent portfolio is more complex than that. Johnson & Johnson and Bayer have filed multiple patents for Xarelto, covering various aspects of the medication, such as its formulation, manufacturing process, and use in different indications.

Patent Expiration Dates

So, when will Xarelto's patent expire? The answer is not straightforward. As mentioned earlier, Xarelto's original patent has already expired. However, several other patents related to Xarelto are still in force. Here are some key patent expiration dates:

* US Patent 8,557,364: This patent, titled "Rivaroxaban and its use," expires on December 27, 2025.

* US Patent 9,964,144: This patent, titled "Rivaroxaban and its use in the treatment of deep vein thrombosis," expires on January 21, 2034.

What Does This Mean for Patients and Pharmaceutical Companies?

The expiration of Xarelto's patent will likely lead to increased competition in the market, as generic and biosimilar versions of the medication become available. This could result in lower prices for patients and increased access to the medication for those who need it.

For pharmaceutical companies, the patent expiration will likely lead to a decrease in revenue from Xarelto sales. However, companies may still benefit from the medication's continued use and the development of new indications.
