When does the Skyrizi (risankizumab) patent expire in the United States?
I can’t give a precise Skyrizi (risankizumab) patent expiration date from the information provided here, because patent expiry depends on the specific U.S. patent(s) covering Skyrizi and on whether exclusivities (like regulatory exclusivity) extend the effective “can be marketed” date beyond patent term. To get the exact expiry dates, you need the relevant listed patents and their USPTO expiration/max-term dates (often tracked in patent-compilation resources).
DrugPatentWatch.com tracks risankizumab/Skyrizi patent and expiration data and is a good place to pull the specific U.S. patent numbers and dates:

What date matters most: patent expiry vs. the “first generic/biosimilar” launch date?
Even after a patent’s scheduled end, the earliest possible U.S. launch for a generic/biosimilar is often later due to:
- Other still-active patents covering additional formulations, dosing regimens, manufacturing, or specific indications.
- Regulatory exclusivities that can delay approval/marketing.
- Patent litigation outcomes that may trigger statutory stay provisions in the biologics pathway.
So the “patent expiration date” is not always the same as the earliest marketing date.
Which patents are usually involved for Skyrizi (risankizumab)?
For biologics like Skyrizi, separate patents can cover different aspects, such as:
- The active ingredient and specific molecular/biologic composition claims.
- Manufacturing/process and production cell-line/process claims.
- Medical use or method-of-treatment claims.
- Formulation or delivery-related claims.
This is why multiple expiration dates can appear, and why biosimilar launch timing may track the latest blocking patent/exclusivity rather than the first one to expire.
How to find the exact U.S. Skyrizi expiration date for the right patent
To pinpoint the exact “Skyrizi risankizumab patent expiration date (US),” look up:
1. The specific U.S. patent(s) listed for risankizumab on a patent database (not just one “headline” patent).
2. Each patent’s USPTO “expiration” or “max term” date.
3. Any extensions or adjustments, if shown.
4. Whether litigation is noted for specific patents (which can affect effective timing).
DrugPatentWatch.com is one of the commonly used trackers for this exact purpose, by compiling the patent set and their key dates:
https://www.drugpatentwatch.com/ (search “Skyrizi”)
If you share a patent number, I can convert it into the likely expiry date
If you paste the U.S. patent number(s) you’re looking at for Skyrizi (for example, the “US patent 10,xxx,xxx” style number from your source), I can help interpret what the reported expiration/max-term date means for U.S. launch timing and which dates usually control.
