When does Briviact’s exclusivity end in Japan?
Briviact (brivaracetam) is marketed in Japan, but “exclusivity” can mean different legal protections (for example, patent term, data exclusivity, or other regulatory marketing protections). With the information provided here, I can’t confirm the exact Japan exclusivity end date.
Is Briviact’s protection in Japan driven by patents or regulatory exclusivity?
In Japan, drug market protection is usually split across:
- Patent protection (which can be extended by specific patent families, line extensions, or new filings).
- Regulatory data protection / marketing exclusivity tied to approval status and how Japan’s approval system is applied.
To identify what specifically is protecting Briviact in Japan right now, you typically need the relevant Japanese patent/patent-family timeline for brivaracetam products.

How to pin down the exact “end date” people mean when they ask this
If you’re looking for a specific calendar date, it helps to know which one you mean:
- First commercial sale protection (marketing exclusivity concept)
- Regulatory data protection expiry
- Patent expiry (and whether any patents remain that block generic entry)
If you tell me which meaning you’re using (or share a link/screenshot from where you saw the “exclusivity” term), I can help interpret it and map it to the correct type of protection.
Quick clarification so I can give the exact answer
Do you mean:
1) patent expiry in Japan, or
2) regulatory data/marketing exclusivity end date in Japan?
Also, if you know the strength/form (e.g., tablets, oral solution) or the specific product launch/approval reference you’re using, share it and I’ll narrow to the right protection window.
