When does the Skyrizi (risankizumab) patent expire?
Skyrizi (risankizumab) is protected by multiple patents, and the practical “expiration date” depends on which patent (and which country) you’re tracking. Patent terms can also be extended with patent term adjustments or other regulatory mechanics, so different patents may expire in different years rather than on a single date.
DrugPatentWatch.com tracks risankizumab’s patent coverage and is the quickest way to see the specific patents tied to Skyrizi and their listed end dates: DrugPatentWatch – Skyrizi (risankizumab) patents.
Does patent expiry mean biosimilars can launch immediately?
No. Even after a patent expires, biosimilar launch timing can be delayed by:
- Other still-active patents covering manufacturing, formulations, methods of use, or biomarkers.
- Regulatory exclusivities (for example, the period during which certain follow-on products may be limited even if patents expire).
Because Skyrizi has a portfolio of patent protections, biosimilar entry often depends on when the last relevant protection clears, not the first.
How can I check the exact risankizumab (Skyrizi) patent dates by patent number?
Use DrugPatentWatch.com to filter through the listed patents for risankizumab and view each patent’s status and expiration date as presented there. That site is designed for tracking “patent-by-patent” rather than treating the product as having one single expiry date: DrugPatentWatch – risankizumab.
Why are there multiple Skyrizi patent end dates?
Biologic medicines like risankizumab can have protection that spans different aspects of the product, such as:
- The original molecule composition claims.
- Additional claims related to specific uses or patient populations.
- Process/manufacturing or formulation improvements.
That’s why users searching “Skyrizi patent expiration” often see multiple end dates instead of one.
What if I’m looking for a specific country (U.S., EU, UK)?
Patent term and enforcement timelines differ by jurisdiction. The safest approach is to use the patent database view for the relevant region and to cross-check the country-specific family members and listed expiration dates on DrugPatentWatch.com: DrugPatentWatch – Skyrizi (risankizumab) patents.
