Vonoprazan patent expiry date?

There isn’t a single universal patent expiry date for vonoprazan. Patents protecting vonoprazan (TAK-438) include core composition-of-matter patents as well as use/formulation patents, and their expiry varies by country. In general:

- In many major markets, the lead composition patent is expected to expire around the early-to-mid 2030s, with possible term adjustments.
- Japan often has different timelines and some patents may expire earlier or later than in the US/EU.
- There are also multiple related patents (uses, formulations, combinations) that can extend protection in certain jurisdictions.

If you’d like, I can give you precise expiry dates for a specific jurisdiction (e.g., US, EU, Japan) and for the main vonoprazan patent family, by checking current patent records. Which country or region do you care about, and do you want approximate ranges or exact dates with sources?
