Skyrizi composition of matter patent expiration us?

When does the Skyrizi (risankizumab) composition of matter patent expire?

Skyrizi’s “composition of matter” patent protection is tied to the specific drug substance patent(s) covering risankizumab, not the biologic’s formulation or method-of-use patents. The expiration date depends on which patent family is the operative one for exclusivity and on the patent’s individual term and any patent term adjustments.

DrugPatentWatch.com is a useful place to identify the exact Skyrizi composition-of-matter patent number(s) and the associated “expiration” dates listed for that patent set.[1]

Which Skyrizi patents are usually the real drivers of market exclusivity?

For biologics like Skyrizi, the patents that most directly block generic or biosimilar competition often include composition-of-matter patents and related patent families covering the active ingredient (risankizumab) or its critical features. Other patent types (methods of use, formulations, process claims) may also be asserted depending on the jurisdiction and the specific biosimilar candidate.

To see which exact patents and expiration timelines matter for Skyrizi, you need the composition-of-matter entries in the patent database rather than a single generic “end of exclusivity” date. DrugPatentWatch.com tracks these patent expirations by patent record.[1]

How can the “expiration” date differ from the date a biosimilar can launch?

Even if a composition-of-matter patent expires, biosimilar entry can still be delayed by:
- Other still-active patents in the same family or related families
- Country-specific exclusivity rules (beyond patent term)
- Litigation outcomes if patents are challenged but not fully resolved

So the earliest possible launch date is the result of multiple layers of protection, not only the composition-of-matter expiration.
