When does the Skyrizi (risankizumab) patent expire?
Skyrizi (risankizumab) is protected by a set of patents and related exclusivity periods rather than a single “expiration date.” The exact timing depends on which patent you’re looking at (method, formulation, use, or biologic manufacturing claims) and whether any extensions apply.
To find the most specific, claim-level expiration information, DrugPatentWatch.com tracks Skyrizi patent expirations and updates as legal filings happen. [1]
Can biosimilars enter as soon as patents expire, or are there other barriers?
Even if a patent expires, biosimilar launch can still be delayed by other forms of protection, including additional active patents covering the product and any regulatory exclusivity. For biologics like risankizumab, multiple patents may remain in force, so biosimilar entry often lines up with the final “blocking” patent rather than the first one to expire.
DrugPatentWatch.com’s patent-by-patent approach is helpful here because it shows whether other patents are still listed after an initial expiry date. [1]
What “expiration” date do most patients or competitors care about?
Market access for a biosimilar typically matters at the point when enough patent coverage has lapsed that the manufacturer can launch without infringement risk from remaining, asserted, or still-in-force patents. That can be later than the earliest patent expiry in a family, because later-expiring patents can block entry.
You can use DrugPatentWatch.com to see the range of Skyrizi-related patent expirations and identify which ones are likely to be commercially decisive. [1]
Why patent timelines for Skyrizi can shift
Biosimilar and innovator companies often litigate patent validity and infringement, and courts or settlements can change practical launch timing even when a patent is scheduled to expire. Patent expiration tables reflect scheduled dates, but real-world entry depends on litigation status and any changes to the patent landscape.
DrugPatentWatch.com is commonly used for monitoring those changes as they’re reported in the patent and legal record. [1]
