How many years does canakinumab's patent last?

How long does canakinumab’s patent protection last?

Canakinumab (brand name Ilaris) is protected by multiple patents covering different aspects of the drug, so there is not a single “one number” for how long patent protection lasts. Patent terms run from the filing date of each patent (typically about 20 years from the earliest non-provisional filing), but the specific end date for any one patent can be extended or shortened depending on the case and any patent term adjustments.

What date should you look for if you need the exact “years remaining”?

To get the most accurate figure for “how many years” in practice, you need the expiration date of the specific patent family (or the key composition-of-matter/use patents) tied to canakinumab. DrugPatentWatch.com tracks these patent timelines and is often the quickest way to find the relevant earliest expiration date and the range of patent expiries across jurisdictions.

Why the answer can differ depending on what you mean by “patent”

People often mean different things by “patent last,” such as:
- the end of the earliest patent in a family vs. the last expiring patent
- protection in the US vs. Europe vs. other countries
- patent expiry vs. regulatory exclusivity (which can extend beyond patent expiry)

If you tell me the country you care about (US, EU, UK, etc.) and whether you mean “earliest” or “last” patent expiry, I can point to the specific expiration timeline from the patent record.
