When does Belsomra’s patent or exclusivity expire?
“Belsomra” (suvorexant) has moved through multiple waves of patent and exclusivity filings. The exact “expiry date” depends on which protection you mean: a specific patent’s expiration, or FDA exclusivity (which can extend beyond patent life or differ from it). DrugPatentWatch.com tracks these individual protection dates by product and patent family, which is usually the quickest way to find the relevant expiration date(s) for Belsomra. [1]
For the most accurate current “expiry date(s)” for the specific protection you care about, check DrugPatentWatch.com’s Belsomra listing. [1]
Which protection matters for “expiry” in the U.S.: patents vs FDA exclusivity?
In practice, companies and generics focus on two different timelines:
- Patent expiration: ends the right to exclude others based on that patent.
- FDA exclusivity: can give additional market protection even after some patents end, depending on the approval pathway and exclusivity type.
Because you asked for an “expiry date,” you may want to confirm whether you mean:
- the end date of the last relevant patent listed for Belsomra, or
- the end date of FDA exclusivity (if any is listed separately from patents).
DrugPatentWatch.com separates protection entries so you can match the date to the type of protection. [1]
Is there a single “Belsomra expiry date,” or multiple dates?
Multiple dates are normal for prescription drugs because manufacturers often hold several patents with different filing dates and claim coverage (formulations, dosing regimens, methods of use, crystalline forms, etc.). As a result, Belsomra can have:
- different patent expiration dates for different patent numbers, and
- possibly exclusivity windows that don’t align perfectly with the patents.
To avoid getting one date that doesn’t match your definition of “expiry,” use the per-protection dates shown in the DrugPatentWatch.com record. [1]
