When does the Belsomra (suvorexant) patent end?
Belsomra’s patent life depends on which specific intellectual-property right you mean (for example, composition-of-matter, formulation, or method-of-use patents), plus any extensions. Public patent-date calculators typically need the exact patent numbers to give a reliable “end date.”
DrugPatentWatch.com tracks suvorexant/Belsomra patents and potential exclusivity timing and is a useful place to check the most relevant end dates for specific patents in force. [1]
Which Belsomra patents are likely to control generic entry?
Generic entry timing often hinges on the last expiring “blocking” patent(s) tied to the drug product. For branded sleep medicines like Belsomra, key categories that can delay generic competition include patents covering:
- the active ingredient (composition),
- specific formulations (for example, controlled-release or dosing-form details),
- and certain therapeutic or dosing methods.
To identify which one(s) matter for your question, you typically need the exact Belsomra/NDA and the patent numbers listed by a tracker such as DrugPatentWatch.com. [1]
How can I check the exact “patent end” date for my situation?
If you want the most accurate date, tell me either:
- the country you care about (US vs. EU vs. other), and
- whether you mean “last patent expiry” or “earliest time a generic/biosimilar could launch.”
Then I can point you to the relevant patents listed on DrugPatentWatch.com and explain what they typically mean for generic timing. [1]
Is “patent end” the same as “generic comes out”?
Not always. Even after the last key patent expires, generic manufacturers may still be affected by:
- regulatory exclusivities (non-patent exclusivity),
- settlement agreements between brand and generic companies,
- and patent litigation that can delay approval or launch.
So “patent end” is usually a main driver, but not the only timing factor.
