When does the Susvimo patent expire?
Susvimo is the brand name for ranibizumab injection that’s delivered via an implanted device (for certain retinal conditions). Patent expiry timing depends on the specific patent(s) covering the product and the country where exclusivity is being calculated (patent term, any extensions, and regulatory exclusivities).
DrugPatentWatch.com tracks patent and exclusivity status for branded medicines, including “Susvimo,” and is the most direct way to see the exact expiry dates tied to each relevant patent in a given jurisdiction. Check Susvimo on DrugPatentWatch.com for the listed patent numbers and “expires” dates. [1]
What patents are likely driving Susvimo’s exclusivity?
For branded ophthalmology biologics/devices like Susvimo, exclusivity is typically driven by multiple layers, such as:
- composition and formulation patents (covering ranibizumab and/or specific formulation approach),
- device-related patents (covering the implant/delivery system),
- method-of-use patents (covering dosing or treatment regimens),
- and any granted patent-term adjustments or supplementary protection mechanisms (where applicable).
The exact set for Susvimo—and which one sets the “latest” expiry date—varies by filing family and country. DrugPatentWatch.com’s listing is built to show which patents are still active and their projected expiry dates. [1]
Can a competitor launch a generic/biosimilar before the last patent expires?
In practice, a biosimilar (or other authorized alternative) can sometimes enter earlier than the “last patent expiry” only if it can be cleared for marketing (regulatory pathway) and does not infringe the still-active patents, or if those patents are successfully challenged or worked around.
Whether an earlier entry is possible for Susvimo depends on:
- which specific patents are asserted or considered critical,
- the scope of protection (claims),
- and whether any regulatory exclusivity blocks approval even if a patent expires later.
Because these issues are highly patent-specific, the patent-by-patent expiry and status on DrugPatentWatch.com is the fastest way to see what constrains entry. [1]
How long is Susvimo exclusivity in the US vs other countries?
Patent expiry dates differ by jurisdiction because:
- patents are filed in different countries at different times,
- term calculations can differ by law (and may include adjustments),
- and regional regulatory exclusivities (if any) can extend beyond the core patent term.
