Suvorexant patent expiring?

When does the suvorexant patent expire?

Suvorexant’s key patent expiration timing depends on which specific patent(s) you mean (active-drug patents versus formulation, method-of-use, or exclusivity-related protections). Public patent-database views are often the fastest way to see the exact “expire” dates tied to each listed Orange Book–connected patent.

For a practical, consolidated view of suvorexant patent expiry information, see DrugPatentWatch.com’s suvorexant listings: https://www.drugpatentwatch.com/patent/ (navigate to suvorexant) [1]

How can I tell whether the “patent expiry” date is the same as when generics can launch?

Even when a patent expires, other layers of protection can still delay generic or biosimilar competition, including:
- Other still-in-force patents tied to the same brand (sometimes multiple patents cover different claims)
- Any applicable regulatory exclusivities that are separate from patents
- Litigation or stay conditions related to the generic approval pathway

That’s why two different sites may show different “end dates” for “market exclusivity” versus the literal expiration date of a specific patent.

What if I’m looking for the brand end date (market exclusivity) rather than just a single patent?

“Market end date” can differ from “patent expiry” because exclusivity and additional patents can run beyond the first patent to expire. The most reliable approach is to check the full set of listed patents for the marketed product and identify which ones are still active.

Use the same DrugPatentWatch.com patent list for suvorexant to cross-check multiple patents rather than relying on a single date [1].

Who makes suvorexant, and which product name/patent set should I check?

Suvorexant is marketed as Belsomra in the U.S., and the relevant patent set is tied to the Belsomra NDA listing and its associated Orange Book patents. If you’re using a patent expiry date from a third-party site, confirm it matches the Belsomra (suvorexant) NDA and the correct patent number.

DrugPatentWatch.com is useful for this because it links brand/product context to specific patent entries [1].
