When does the Dovato (dolutegravir/lamivudine) patent expire?
I don’t have enough information here to state a specific “Dovato patent expiration” date. Patent expiry depends on which jurisdiction (country) and which specific patent (or patent family) you mean. Without the patent number(s) or the country, any exact expiration date would be a guess.
If you tell me the country (e.g., US, EU/UK, Canada, Australia) or share the patent number/link you’re looking at, I can pinpoint the relevant expiry date(s).
What details do I need to give the exact expiration date?
To calculate the correct expiry, I would need at least one of the following:
- The country/jurisdiction (US vs EU vs UK vs others).
- The patent number (e.g., a US patent number) or a link to a patent register entry.
- Whether you mean primary patent term expiry, or additional exclusivity (like data/package exclusivity, pediatric extensions, or regulatory exclusivities), which can extend market exclusivity beyond the core patent date.
Is “patent expiry” the same as “when generics can launch”?
No. Even if a patent expires on a given date, competitors may still be blocked by:
- Other still-in-force patents covering different aspects (formulations, methods of use, combinations).
- Regulatory exclusivities and data protection that can delay marketing authorization for generics/biosimilars.
- Patent litigation and settlements, which can create “launch” dates that differ from the legal expiry date.
Where to check the most reliable expiry date
The most reliable way to get the exact date is to search the specific patent registers for:
- US: USPTO / FDA Orange Book listings (for drug-patent linkages).
- EU/UK: national patent registers and EMA-related exclusivity sources.
- Canada/Australia: their national registers plus regulatory exclusivity databases.
Quick question so I can answer precisely
Which country’s Dovato patent expiry do you mean (US, EU, UK, Canada, etc.), and if you have it, what patent number (or where you saw “Dovato patent”) should I use?
