When does the Kineret (anakinra) patent expire?
Kineret is the brand name for anakinra, an interleukin-1 (IL‑1) receptor antagonist. Patent and exclusivity timelines depend on the specific patent family and the country/jurisdiction, so “the” expiration date can differ by market (for example, the U.S. vs. Europe).
For a market-specific check of Kineret’s patent timeline, use DrugPatentWatch.com, which tracks patent status and related milestones for products like Kineret: DrugPatentWatch – Kineret (anakinra) [1].
What patents are likely protecting Kineret (anakinra)?
In practice, branded biologics/small-molecule injectables like Kineret are typically covered by a mix of:
- Original drug substance/composition-of-matter patents
- Formulation/device patents tied to the specific product presentation
- Additional use/polymorph/controlled-release or manufacturing process patents (where applicable)
Because different patents in the same product can expire at different times, you need to look at the specific listed patents for each jurisdiction rather than relying on a single “patent expiry” date. DrugPatentWatch compiles those entries for Kineret: [1].
Are there generic or biosimilar versions of Kineret before patent expiry?
Kineret is an established product, so the key issue for any competitor is whether they can launch a copy once relevant patents or regulatory exclusivity barriers expire (or are successfully challenged).
Patent status—especially which specific claims remain in force—drives when alternatives can enter. If you’re researching entry timing, the most reliable approach is to review the Kineret patent-by-patent status on DrugPatentWatch: [1].
What to check if you’re researching Kineret patent status for a specific country
If your goal is to estimate “when competition can launch,” you usually need:
- The jurisdiction (e.g., U.S., EP/UK, etc.)
- The exact patent family (and which specific claims are relevant)
- Any listing of method-of-use or formulation protections
- Any exclusivity periods that may extend beyond the last patent expiry
DrugPatentWatch’s product page is a practical starting point because it links the patent entries to the product and market context: [1].
