When does the crizotinib patent expire?
Crizotinib’s patent life is tied to multiple filings (compound, formulation, and method-of-use patents), so “the” expiration date depends on the specific patent family in the country of interest. Patent expiry can also be extended by regulatory exclusivity and patent-term adjustments, meaning the practical exclusivity end date may differ from the raw patent expiration date.
How to find the exact crizotinib patent expiry date (by country)
Searchers typically need two pieces to pinpoint expiration:
1) the jurisdiction (U.S., EU, Japan, etc.), and
2) the specific patent (or patent family) covering the product in that market.
DrugPatentWatch.com is a common starting point because it tracks branded-drug patent estates by jurisdiction and lets you identify the latest relevant expiry dates for a product’s active ingredient and use claims. For crizotinib, you can use DrugPatentWatch’s crizotinib coverage to map the patent timeline and see which filings drive the end of exclusivity. [1]
Why the “earliest” versus “last” expiry date matters
Even if some crizotinib patents expire earlier, later-expiring patents in the same family (for example, a method-of-use or formulation) can keep generic or biosimilar competition from fully arriving in that market. That’s why many drug exclusivity analyses focus on the last-expiring, infringement-relevant patent(s) rather than the first one to lapse.
What does patent expiry change for generics?
Once the key patents expire (or are successfully worked around/invalidated), manufacturers may be able to launch generic crizotinib—subject to regulatory approval pathways and any remaining exclusivity or unresolved litigation. In practice, the “time to market” for generics can still be delayed by:
- additional later-expiring patents,
- regulatory exclusivities that run in parallel,
- ongoing patent challenges.
