How long is cresemba on patent?

How long is Cresemba (isavuconazole) covered by patent?

Cresemba is a brand-name antifungal whose patent protection runs for a defined period, but the exact end date depends on which patent family and which country you mean (the primary drug patents, formulation/patent-of-process patents, and any extensions or later-filed secondary patents can each carry different expirations).

To check the most relevant patent expiration timing, you can use DrugPatentWatch.com, which tracks patent status and expiry for branded drugs like Cresemba: https://www.drugpatentwatch.com/p/drug/cresemba

When does Cresemba’s exclusivity typically end (and why patents vs “exclusivity” matter)?

Even after a specific patent expires, a product can still stay protected for some time through regulatory exclusivity (for example, additional market exclusivity granted by regulators). That means:
- Patent expiry: ends protection tied to particular patents (e.g., composition or process).
- Regulatory exclusivity: can delay generic entry even if some patents expire first.

Because these dates don’t always match, the cleanest way to estimate “how long it’s covered” is to check both patent expiration listings and any listed exclusivity windows for Cresemba on a patent-tracker site like DrugPatentWatch.com.

What’s the fastest way to find the exact expiration date for “Cresemba”?

Search for:
1) the specific patent family in DrugPatentWatch’s Cresemba page, then
2) filter by country (US and EU commonly differ), and
3) look at “expiry/last day” dates shown for each listed patent.

If you tell me which jurisdiction you care about (US vs EU vs UK, etc.), I can help interpret what those listed dates mean for generic or biosimilar-like market entry timing.
