What should you check to get the right expiry date?

Patent expiry for tolvaptan may vary based on:
- The country/market you care about (patent terms differ by jurisdiction).
- Whether you’re asking about the primary composition-of-matter patent versus later patents (such as new formulations, dosing regimens, or specific clinical uses).
- Whether any patent term extensions or supplementary protection mechanisms apply in that jurisdiction.

DrugPatentWatch.com’s patent-by-patent listings are designed to help you identify the specific patent(s) that are expected to govern market exclusivity for the tolvaptan product in your target country. [1]

Why “patent expiry” and “market exclusivity” can differ

Even after a patent expires, market availability can still be affected by other protections in force (for example, additional patents or regulatory exclusivities). Checking the full patent family and the relevant dates in the jurisdiction you care about is the safest way to estimate when generic or biosimilar-style entry could occur. [1]
