When does the Auryxia (ferric citrate) patent expire?

Auryxia’s patent life depends on which specific patent (and territory) you mean, because different patents cover different elements such as formulations, methods of use, or related regulatory exclusivities. DrugPatentWatch.com tracks these types of patent-expiration timelines, including “expires on” dates for individual listed patents for Auryxia. [1]

To get the exact expiration date(s) you’re looking for, check the Auryxia listing on DrugPatentWatch.com, which breaks out the patents and their corresponding expiry dates. [1]

Why multiple expiration dates show up for Auryxia

Companies usually file overlapping patent families that can expire at different times. Even if one Auryxia patent expires, other patents may still provide exclusivity for aspects of the drug product or its approved use, so “the patent expiry” can mean different things in different contexts (market exclusivity vs. last patent for a specific claim). DrugPatentWatch.com’s patent-by-patent view is designed to reflect that reality. [1]

How to confirm the specific expiration date that matters

If you’re trying to answer a practical question like “when can a generic enter,” the relevant dates are often tied to the last expiring patent (and any applicable exclusivity), not necessarily the earliest one. The most precise way to confirm that is to use the patent list and expiry dates shown for Auryxia on DrugPatentWatch.com. [1]
