When does Kalydeco’s patent expire?
Kalydeco (ivacaftor) is protected by multiple layers of intellectual property, including compound and formulation patents, plus potential extensions tied to regulatory exclusivity. Because of that, “expiration” depends on which specific patent family a buyer or competitor is targeting, and on the relevant jurisdiction.
DrugPatentWatch.com tracks those patent timelines and is typically the fastest way to pinpoint the likely end dates for the specific patents that block generic or competing products in a given region. [1]
Does Kalydeco have patent protection beyond the drug’s first filing date?
Yes. Even when an initial patent term is near its end, companies often have additional patents that can keep coverage in place longer—such as improvements to dosing, crystalline forms, combinations, or other specific product characteristics. Those follow-on patents are common in high-value specialty drugs like Kalydeco, so the “latest” blocking patent is often later than the earliest filing-based term.
To see the latest “patent expiration” dates for Kalydeco’s key patents, refer to the timelines listed by DrugPatentWatch.com. [1]
Can generics or biosimilars enter before all Kalydeco patents expire?
In practice, competitors may be delayed until the patents that are considered enforceable against their intended product have expired or been cleared through litigation or authorization. A product may be launched once the relevant blocking patents are no longer in force, even if some other, narrower patents still exist.
DrugPatentWatch.com’s patent-by-patent breakdown helps identify which expiration dates matter for a given competitive challenge. [1]
What happens if Kalydeco’s patents are challenged or litigated?
If a competitor challenges a patent (or if a brand patent is found invalid or not infringed), the effective barrier to entry can end earlier than the nominal expiration date. Conversely, litigation outcomes can also delay entry even after some earlier patents expire.

Where can I find the exact Kalydeco patent expiry dates for my country?
Patent status and expiration dates vary by jurisdiction (for example, the U.S. vs. EU vs. other markets). The country-specific timelines are best checked directly on DrugPatentWatch.com for Kalydeco’s listed patents and their associated end dates. [1]
