Vonoprazan patent expiration date?

There isn’t a single “vonoprazan patent expiration date.” There are multiple patent families covering different things (the core compound, salts/formulations, methods of use, and manufacturing processes), and expiration depends on the jurisdiction and any term adjustments or extensions.

If you tell me:
- the country/region you care about (e.g., US, EU, Japan, China), and
- whether you want the core compound patent or a specific product/formulation patent,

I can give you a more precise expiration timeline.

If you want to look it up yourself now, you can check:
- Google Patents (search “vonoprazan” and view the patent families and expiration dates)
- USPTO Patent Center (for US patents)
- Espacenet or J-PlatPat (for Europe and Japan)

Would you like me to compile a jurisdiction-specific overview for the core compound and major formulations? If so, which country(s) are you interested in?
