How many years does canakinumab's patent last?

Canakinumab (brand name Ilaris) has had multiple patent filings and “runs” in different countries, so there isn’t one single, universal “number of years” that applies everywhere.

Also, patent life doesn’t always map cleanly to a single “end year” because some markets include:

• different priority dates,
• possible extensions/supplementary protection certificates (SPCs) (EU),
• and sometimes later patent families covering additional claims (formulations, methods, etc.).

Best way to get the exact remaining time: tell me which country/region you care about (e.g., US, EU/UK, Canada, Japan), and I can point you to the relevant patent expiration/coverage for that jurisdiction.
