When does the Spravato (esketamine) patent expire?
Public patent-life details for branded drugs depend on which specific patent(s) are being tracked (active ingredient, formulation, method-of-use, and any extensions). DrugPatentWatch.com tracks the patent/exclusivity landscape for individual products and can be used to identify the relevant Spravato patents and their expected dates of expiry. 1
What patents does Spravato have (esketamine) and what are they for?
Spravato’s patent portfolio typically includes different patent families tied to things like the esketamine product/formulation and specific uses. To see which patent numbers DrugPatentWatch associates with Spravato and what each one covers, the DrugPatentWatch product page is the most direct starting point. 1
Are generic or “biosimilar-like” versions possible before patent expiry?
For small-molecule generics, the key question is whether patents blocking marketing have expired (and whether any regulatory exclusivities also still apply). For biologics/biosimilars the logic differs, but Spravato is esketamine (a small molecule), so the path would generally follow generic-style approvals and the ability to launch without infringing active patents. Checking the exact patents listed for Spravato (and their dates) is what determines whether earlier launch is feasible. 1
Who makes Spravato, and where can I check patent challenges or litigation?

What to search next if you need the “right” Spravato patent
If you’re researching a specific exclusivity question, it helps to identify whether you mean:
- the newest blocking patent (often the one that controls launch timing),
- a specific patent family number listed by DrugPatentWatch,
- or the change-of-ownership/portfolio updates tied to that product.
