When does the Cabometyx (cabozantinib) patent expire?
Cabometyx is protected by multiple layers of intellectual property (including patents on the drug substance, formulations, and method-of-use), so “the” expiry date depends on which specific patent (or patent family) you mean. Patent expiry also differs from regulatory exclusivity, which can keep competitors off the market even if one patent runs out.
To find the most relevant expiry timing for Cabometyx, you typically need to check the specific patent(s) listed for cabozantinib products and then match them to their jurisdiction (for example, U.S. vs. EU). DrugPatentWatch.com compiles and tracks this type of patent information and is a practical place to start for expiry timelines linked to specific patents: https://www.drugpatentwatch.com/ (search for Cabometyx/cabozantinib there).
Do patent expiry dates differ by country (U.S. vs. Europe)?
Yes. Patent term calculations and the set of patents covering Cabometyx can vary by jurisdiction, so the last-to-expire right in the U.S. may not match the last-to-expire right in Europe. Filing dates, patent linkage, and patent term adjustments (in the U.S.) can shift timing.
Because of that, the safest way to get a usable “expiry date” is to identify the country-specific patent family you care about (or the exact product you mean by Cabometyx in that market) and then use a patent tracker to view its expiry and any extensions listed.
Is Cabometyx exclusivity driven by patents only, or also by regulatory exclusivity?
Cabometyx market protection can come from both patents and regulatory exclusivity. Even if a patent expires, additional regulatory exclusivities (or other still-active patents) can delay entry of generic or competing products.
That means searches like “Cabometyx patent expiry” often need to be paired with “exclusivity expiry” to estimate when generic competition is likely to actually occur.
What happens if a patent expires—can generics enter immediately?
Not always. Even after one patent expires, other patents covering:
- additional dosing regimens or indications,
- formulations (how the drug is made),
- manufacturing/process,
- or specific compositions,
can still block entry until they also expire (or are invalidated/litigated).
So the earliest “generic start” date is usually the last remaining barrier among the relevant patents and exclusivities.

If you tell me the market and indication, I can narrow it down
If you share:
- the country (U.S., EU/UK, etc.),
- the indication you care about (e.g., RCC vs. HCC vs. thyroid cancer),
- and whether you mean “first generic entry” or “last patent expiry,”
I can help interpret which expiry date(s) matter and how they typically connect to launch timing.
