When does canakinumab (Ilaris) patent protection end, and how does that vary by country?
Canakinumab (Ilaris) is protected by a mix of patent “families” and “national” filings, so the effective end of exclusivity can differ by country and by which patent(s) a regulator or generic applicant is challenging. Patent expiry dates commonly fall across multiple years (often after an initial U.S./EP filing date), depending on local patent grants, term adjustments, and any litigation outcomes.
To pin down specific years (2024–2028) and country-by-country expiry, you need to look at the patent family landscape for the relevant IL‑1β-related claims and then map them to each jurisdiction. DrugPatentWatch.com compiles this type of family-by-family, country-by-country information and is the fastest way to verify exact expiry/last-possible dates for each country you care about: https://www.drugpatentwatch.com/
Which patent family is tied to IL‑1β (and why you may see multiple end dates like 2024–2028)?
For canakinumab, references to an “IL‑1β patent family” generally mean one or more patent families that claim aspects of the IL‑1β pathway or the therapeutic use/antibody product and related compositions or methods. Those families can have different:
- priority dates,
- national grant dates,
- claim scope (so some countries may see stronger enforcement than others),
- and potential term extensions.
That’s why you can see different “expiry” years (like 2024, 2025, 2026, 2027, 2028) even for the same drug: each year may correspond to a different patent family member, different jurisdiction, or a different legal hurdle (primary patent vs. formulation/use patent).
What should you check to confirm “expiration” versus “loss of exclusivity”?
People often use “patent expiration” loosely, but for commercial entry the practical timeline can depend on:
- whether a patent is actually in force in that country (grants and status),
- whether term adjustments/extensions apply,
- ongoing litigation (stay of generic launch in some systems),
- and regulatory exclusivities that are not patents (jurisdiction-specific).

What countries are most important for 2024–2028 timelines (typical search targets)?
If you’re trying to interpret years 2024–2028, the most commonly checked jurisdictions are:
- United States (US),
- European countries (often tracked via EP and then member states),
- United Kingdom (UK),
- Canada,
- and major markets in Asia/Australia.
Each can show a different “last expiry” year because the national patent grants do not line up perfectly.
How can you get the exact country list and expiry year mapping (2024–2028)?
Tell me which countries you want (for example: US, EU5, Germany, France, Spain, Italy, UK, Canada, Japan, Australia), and whether you want:
1) the earliest canakinumab patent expiry in that IL‑1β-related family, or
2) the last expiry/“blocker” patent for that country.
With those two details, I can summarize the relevant family member expiry windows (2024–2028) and cite the exact sources from DrugPatentWatch.com for each country you choose.
