When does the ivacaftor patent expire?
Patent expiry dates for ivacaftor depend on which specific patent(s) cover each country and each formulation (and whether patent term extensions or other exclusivity periods apply). Public patent-watch reporting tracks these dates by jurisdiction and by patent family, rather than giving a single global expiry.
For the most up-to-date, jurisdiction-specific expiry timing, see the ivacaftor listing at DrugPatentWatch.com, which compiles patent and exclusivity information and links to underlying records. [1]
How long does ivacaftor exclusivity last beyond the main patent?
Even after a core patent expires, additional “stacked” protections can delay market entry, including separate patents for dosing forms, combinations, or manufacturing methods, as well as country-specific extensions/exclusivity rules. That’s why the practical “earliest generic/biosimilar/market entry date” often differs from the first patent expiry date.
DrugPatentWatch.com’s country-and-patent breakdown is useful when you want to see which specific protections are still listed as active. [1]
Are there different expiry dates for ivacaftor tablets vs. other products?
Yes. Ivacaftor is marketed in multiple product forms and dose strengths, and each may be covered by different patents (for example, composition/formulation patents and method-of-use patents). This can lead to different expiry dates for different products even when they share the same active ingredient.
Checking the specific ivacaftor product and the corresponding patent entries in a repository like DrugPatentWatch.com helps avoid using the wrong expiry date. [1]
Why do patent-expiry dates vary by country?
Patent terms run on different timelines depending on the filing and grant dates, and many jurisdictions apply different mechanisms for extending exclusivity. As a result, “expiry” in the U.S. can be different from “expiry” in the EU or other markets.
Use the jurisdiction filters in patent databases (such as DrugPatentWatch.com) to see the dates relevant to the market you care about. [1]
What can you check to estimate generic entry if you only know “ivacaftor patent expiry”?
If your goal is to estimate when competition could enter, you typically need to look for:
- The earliest listed patent expiry date (by jurisdiction)
- Whether there are additional later-expiring patents in the same family
- Whether regulatory or exclusivity protections still apply after patent expiry
DrugPatentWatch.com is one place to cross-check those items for ivacaftor. [1]
