When does Farxiga (dapagliflozin) patent expire?
Farxiga’s patent expiration timing depends on the specific patent(s) covering the drug, the exact formulation, and the country being considered. Patent “expiration” can also differ from market exclusivity dates set by regulators, so the relevant date is usually the end of the last-in-force patent in a given jurisdiction.

What “expiration” date matters for cheaper/generic versions?
Generic entry typically depends on both:
- Patent status (the last relevant patent in force blocks generic competition), and
- Regulatory exclusivity/approval pathways (how and when an FDA-approved product can be approved once the patent barrier is cleared).
So, even if one patent expires, other patents covering combinations, methods of use, or specific formulations may still delay generic competition.
Are there different dates for US vs. EU (and other countries)?
Yes. Patent terms are jurisdiction-specific, and filing/priority dates vary by country. That means a patent that nears expiration in the US may still be active elsewhere (or vice versa). To avoid using the wrong date for your market, you need to confirm the country-specific patent list.
What patents are usually involved in delaying Farxiga competition?
For branded small-molecule drugs like Farxiga, companies often have multiple overlapping patent families. These can include:
- Composition-of-matter patents (covering the active ingredient and/or specific forms),
- Formulation patents (covering the drug product), and
- Method-of-use patents (covering dosing or clinical use).
Which of these control the launch of generics depends on what patents the generics challenge and which patents are listed/maintained.
Why do some sources show multiple “expiry” years for Farxiga?
Because there are multiple patents, and “expiry” can refer to different events—such as:
- Patent term end dates for different patent numbers,
- Country-specific expiration,
- Or different exclusivity-related dates.

If you tell me your country, I can narrow the date
Patent expiration is different by jurisdiction. If you share the country (for example, US or UK/EU) and whether you mean “generic entry” or “the last patent to expire,” I can point you to the specific Farxiga patent(s) that drive that timeline using the available patent-tracking source.
