When does the patent run out on sprycel dasantanib?

Sprycel is dasatinib. There isn’t a single, universal expiration date for its patent. Protection comes from multiple patent families (the core compound patent, plus patents on uses, formulations, manufacturing, etc.) and is also affected by regulatory exclusivities that vary by country.

If you want a precise expiration date, please tell me:
- which country or region you’re interested in (e.g., United States, European Union, Japan),
- and whether you want the core “composition of matter” patent or a specific use/formulation patent.

I can then give you country-specific dates and point you to sources (patent databases like Google Patents, USPTO/EPO, and regulatory exclusivity notes).
