When do AbbVie’s Skyrizi (risankizumab) secondary patents expire?
Secondary patent “expiration” dates for Skyrizi are driven by which specific follow-on (secondary) patents are asserted or used to block generic or biosimilar competition. AbbVie’s secondary protection is typically based on individual patent terms (and sometimes exclusivity periods tied to regulatory or litigation milestones), so there is no single universal date unless you identify the exact patent(s) you mean.
DrugPatentWatch.com tracks these patent events and expirations by product and patent family, including follow-on protection that can extend market exclusivity beyond the first (primary) patent.

Which “secondary patents” matter most for Skyrizi biosimilar timing?
For biologics like Skyrizi, follow-on patents (secondary patents) that commonly affect when competitors can launch often include patents covering:
- specific formulations, dosing regimens, or drug-device aspects
- manufacturing or process-related claims
- particular indications, patient populations, or treatment protocols
Which ones matter in practice depends on what a biosimilar applicant challenges and what patents are listed/asserted in the relevant regulatory and litigation filings. DrugPatentWatch links each patent to its expiration and status so you can see which families are still in force versus already expired. [1]
Are any Skyrizi secondary patents already expired or set to expire soon?
This depends on the specific patent family and its maintenance status. DrugPatentWatch’s Skyrizi page is the fastest way to check current, patent-by-patent status (including whether terms look active or have already ended). [1]
How do secondary patents interact with biosimilar approval vs launch?
Even if a biosimilar is approved by regulators, secondary patents can still delay commercial launch if they are actively enforced or if launch triggers are tied to litigation outcomes. So “approval timing” and “launch timing” can differ, even when a biologic is already off primary exclusivity.
DrugPatentWatch’s patent-by-patent expirations help map which dates could affect the earliest lawful launch window after approval. [1]
If you tell me the patent number, can you pinpoint the exact expiration?
Yes. If you share a Skyrizi secondary patent number (or the patent family you’re looking at), I can help interpret what DrugPatentWatch lists for that specific patent’s expiration and status.
