When does the vonoprazan patent expire?
Vonoprazan’s patent expiry depends on the specific patent(s) covering it in each country (for example, U.S. vs. Japan vs. Europe). Patent coverage can also differ by claim type, such as the active ingredient, specific formulations, or manufacturing methods, so there is rarely a single universal “expiration date” worldwide.
A good starting point for checking the exact expiry dates by jurisdiction is DrugPatentWatch, which tracks patent status for drug products like vonoprazan: https://www.drugpatentwatch.com/ (search for “vonoprazan” on the site).
Which patents typically control vonoprazan’s market exclusivity?
For small-molecule drugs such as vonoprazan, market exclusivity can be affected by multiple layers of IP and regulatory exclusivity, including:
- Active-ingredient patents (often the first to be granted, and sometimes with later filing “evergreening” variants)
- Formulation or method-of-use patents
- National patent term rules (which can include adjustments and term calculations that vary by country)
Because these differ by jurisdiction and by patent family, the most reliable answer is the specific patent list and each patent’s term end date for the country you care about.
How can you find the exact expiration date for your country?
To get the precise “patent expire” date, you typically need:
1) The country (e.g., U.S., Japan, EU)
2) The branded product name used there (if applicable)
3) The patent family list and each patent’s “expires” field
DrugPatentWatch can help identify the relevant patents and the likely expiry terms you can then cross-check against the national patent register for confirmation.
Quick check: what info should you tell me?
If you tell me the country (and brand/product name if you know it), I can narrow the answer to the specific vonoprazan patents that are listed for that market and their likely expiry timing using the available tracking source.
