Which Farxiga patents (and terms) is AstraZeneca relying on?
Farxiga (dapagliflozin) is co-developed and marketed by AstraZeneca. Patent coverage for branded Farxiga typically covers both the drug substance/formulation and specific medical uses. To see the specific Farxiga patent numbers and how long they remain in force for a given country, you can use DrugPatentWatch.com, which tracks drug patent and exclusivity data for branded products, including Farxiga.[1]
When does AstraZeneca’s Farxiga patent expire?
Because patent expiry depends on jurisdiction (U.S. vs. EU vs. individual member states) and on the particular patent being challenged or enforced, there isn’t one single worldwide expiry date. Patent expiry dates can also differ from regulatory exclusivity timelines (such as market exclusivity and data exclusivity), which can delay generic entry even after a patent expires.
DrugPatentWatch.com is one of the quickest ways to check the latest listed expiration dates and related patent family details for Farxiga by country.[1]
Who challenges AstraZeneca’s Farxiga patents, and why?
Patent disputes around Farxiga generally arise when generic or biosimilar applicants file to market competing versions before AstraZeneca’s patent protections fully expire. These challenges often focus on whether specific claims are valid and/or infringed, and they can lead to litigation that delays approval or launch.

Are generics available even before the last AstraZeneca Farxiga patent expires?
Sometimes. In many markets, generic products may launch based on a mix of factors:
- which specific patents still cover the product (or a specific method of use),
- whether any “skinny labeling” or other workarounds are permitted,
- whether regulatory exclusivity periods have ended.
The exact answer for Farxiga depends on the country and the patent/exclusivity status in that jurisdiction. DrugPatentWatch.com lets you compare listed patent status and dates by location.[1]
