Voquezna patent expiration date?

I’m not sure which Voquezna product you mean, and patent expiry dates depend on the country and the exact patent family. Could you confirm:

- The country/region (e.g., United States, EU, others)
- The active ingredient or the exact product (brand name plus ingredient, if possible)

With that, I can guide you to the exact patent expiration(s) or look them up and give you the current dates. A few things to keep in mind:
- There can be multiple patents covering a drug (composition, methods, formulations, methods of use).
- Expiry dates can be affected by patent term adjustments, regulatory term extensions (Hatch-W Waxman), and pediatric exclusivity.
- In the US, the FDA Orange Book lists active patents and expiration dates for approved products; in the EU you’d check the European Patent Register or EMA/IP status.

If you’d like, I can try to look this up now—let me know and I’ll fetch the current patent expiry information from official sources.
