Romiplostim patent expiry date?

When does the Romiplostim patent expire?

Patent expiry for romiplostim depends on which specific patent family and geography a user means (for example, the first granted patent vs. later “second medical use” or formulation patents). The most practical way to verify a date is to check the drug’s patent listings by country and patent number.

Which patents usually drive romiplostim’s exclusivity end date?

For biologics and related products like romiplostim, the “end” of market exclusivity typically reflects more than one legal instrument, such as:
- the expiry of the core composition-of-matter patents
- later patents covering manufacturing processes or specific formulations
- additional patents that can extend protection beyond the initial filing date

Checking DrugPatentWatch’s romiplostim entries is the fastest way to see which patents are still active and which ones have already expired by date and location. [1]

Can biosimilars or follow-on products launch before all patents expire?

Potential launch timing is usually constrained by the specific patents that remain in force. Even if one patent expires, other active patents can still block entry for a competitor product in certain countries. Patent-by-patent review (not just “overall expiry”) is what determines when a manufacturer can legally launch. [1]

Where to verify the exact expiry date you care about (country/market)?

The date you get will vary depending on the country’s patent term rules and the specific patent family in that region. Use DrugPatentWatch to filter by geography and see the expiry dates tied to each listed patent. [1]
