When does semaglutide’s patent protection expire in Singapore?
I don’t have the specific patent expiry dates for semaglutide in Singapore in the information provided here, so I can’t give an accurate “expires on [date]” answer.
In practice, semaglutide’s market exclusivity in Singapore can be tied to multiple legal layers, such as different patents (covering the molecule, formulations, dosing devices, and manufacturing processes) and any separate exclusivity periods that may apply. That means the “latest expiry” can differ from the first patent to expire, and the date you see quoted online may reflect a particular patent family rather than all relevant protection.
What date should you look for if you need the exact expiry?
To find the correct Singapore date, you typically need to identify the specific semaglutide patent(s) held in Singapore and their individual expiry terms, then check whether any supplementary protection or other exclusivity protections apply for the marketed product (for example, Ozempic/Wegovy for different indications and pack sizes).
The reliable way is to:
1) Locate the semaglutide patent family in Singapore’s patent records (by applicant/assignee and compound/claim keywords).
2) Check each relevant Singapore filing for its grant date and term, then calculate expiry based on Singapore’s rules for that patent type.
3) If you’re tracking “launch protection” rather than just patent expiry, also check for data/exclusivity provisions that may extend market exclusivity beyond the first patent expiry.
Why online “patent expiry dates” often don’t match in Singapore
Different sources may cite:
- a patent expiry date for a different jurisdiction,
- the expiry for only one patent in a family (not the last),
- a different drug salt/strength/formulation variant,
- a date based on US/EP timelines that doesn’t map cleanly to Singapore.
Because semaglutide is protected by multiple overlapping patents, the Singapore date you care about is usually the expiry of the last blocking right for the specific product/version you’re tracking.
If you tell me the product name, I can narrow the search
If you share which product you mean (for example, Ozempic vs Wegovy, or the indication/strength), I can help you identify what to check and what documents typically determine the Singapore expiry timing.
