Who holds the Belsomra (suvorexant) patents in Australia?
Belsomra is the brand name for suvorexant. Patent ownership and the specific Australian patent numbers can vary by product component (active ingredient vs. formulation vs. method of use) and by jurisdictional filing strategy. To identify the controlling Australian rights and assignees, you typically need the Australian patent record for suvorexant/Belsomra and any related SPC/exclusivity filings.
When does the Belsomra patent/exclusivity expire in Australia?
Expiration timing in Australia depends on which patent(s) and any supplementary protection (if applicable) apply to the marketed product. The most reliable approach is to match the exact Australian patent(s) covering suvorexant to their filing/term data and then check whether any further regulatory protection extends exclusivity.
If you want, share the link or the exact patent number you’re looking at, and I can help interpret what its term means for when generic entry could be possible.
Are there generic or biosimilar challenges to Belsomra in Australia?
Whether generic entry is possible and when it can occur hinges on the specific Australian patents still in force and any litigation or settlement outcomes. If a competitor is preparing an Australian market launch, they usually rely on one or more of the following: patent invalidity arguments, non-infringement positions, or waiting for certain claims to expire.

What should you check to confirm the exact “Belsomra patent Australia” answer?
Because search results often mix different jurisdictions, the key is to confirm:
- the Australian patent number(s) tied to suvorexant/Belsomra
- who the assignee is on the Australian record
- whether the patent is still active (not lapsed/withdrawn)
- which claims cover the marketed product use/formulation
If you paste the patent number, can you tell me the Australian expiry date?
Yes. If you paste the Australian patent number (or the assignee name + patent title), I can explain what typically drives the expiry date in Australia (term, priority, and whether any additional protection is claimed) and what it means for competition.
