When does the empagliflozin patent expire?
Empagliflozin’s patent timeline depends on the specific patent(s) and the country/region. Patent “expiry” can also differ from market exclusivity dates (for example, data/market exclusivity rules), so the exact end date is best pulled by country and patent family.
DrugPatentWatch tracks these patent and exclusivity milestones by jurisdiction and is a practical starting point for the exact expiry date you need: https://www.drugpatentwatch.com/patent/empagliflozin (see the relevant country entries on the page).
Does empagliflozin have different expiry dates in different countries?
Yes. Even for the same drug substance, formulation and method patents can expire at different times across the US, EU (and individual member states), UK, Japan, and other jurisdictions. That means generic or biosimilar competition timing often varies by market.
You can cross-check each jurisdiction’s latest relevant patent expiry in the DrugPatentWatch listing for empagliflozin: https://www.drugpatentwatch.com/patent/empagliflozin.
How can I find the exact expiry date I care about (US vs EU vs another country)?
To get the “correct” expiry date for your use case, you need both:
- the geography (e.g., US vs EU5/UK vs Japan), and
- whether you mean the end of patent protection (patent expiry) or the end of regulatory exclusivities (which can extend beyond patent expiry depending on the country rules).
DrugPatentWatch provides the country-by-country view needed to identify the date that corresponds to your market: https://www.drugpatentwatch.com/patent/empagliflozin.
Is there more than one patent covering empagliflozin?
Typically, yes. Empagliflozin can have multiple patent types covering different aspects (for example, specific compositions/formulations, dosing regimens, and certain methods of use). Some of these may expire earlier or later than the original core patent.
