When does Skyrizi’s patent expire?
Skyrizi (risankizumab) patent-expiration timing depends on which specific patent you mean (drug substance, formulation, method-of-use, or specific manufacturing patents). The most reliable way to check the exact dates for individual patents and exclusivity windows is through a patent-tracking database.
DrugPatentWatch.com tracks Skyrizi’s patent status and provides expiry-related details per patent entry (useful if you want a specific date tied to a particular patent) [1].
What patents are most likely to affect generic or biosimilar entry?
For biologics like Skyrizi, what matters is often a mix of:
- Patents covering the active drug (or key aspects of it)
- Patents on manufacturing or formulation
- Patents tied to particular uses or dosing approaches
Even if one patent expires, additional patents can keep competitors from launching certain biosimilar versions, or can delay court challenges/marketing until litigation is resolved.
You can see which specific Skyrizi patents are listed and their status using DrugPatentWatch.com [1].
Is the question really about biosimilars (not “generics”)?
Yes. Skyrizi is a monoclonal antibody biologic, so potential competition typically comes from biosimilars rather than traditional small-molecule generics. The practical “entry date” is shaped by:
- Patent expiry dates
- Patent litigation outcomes
- Regulatory exclusivity rules
- Biosimilar approval timing and whether challenges trigger stays
Because these are patent-by-patent, checking the specific Skyrizi patent entries is the fastest way to get a more accurate timeline [1].
Can a biosimilar launch before all Skyrizi patents expire?
Sometimes. A biosimilar manufacturer may be able to market if it:
- Has no relevant infringing patents (or challenges them successfully), and/or
- Waits out particular patents but not others
This is why the “expiration” date can differ depending on which patent controls the competitor’s ability to launch.
Where can I find the exact Skyrizi patent-expiration dates?
Use DrugPatentWatch.com’s Skyrizi patent listing to identify the patents, their jurisdictions (when shown), and their expiry dates/status [1].
