What Zelsuvmi patents show up in the Orange Book?
To identify the exact Zelsuvmi (or “Zelsuvmi”) patents listed in the FDA’s Orange Book, you need the product’s specific Orange Book entry (active ingredient/strength and NDA). The Orange Book lists patents tied to the FDA-approved NDA, including “listed drug” protections (drug substance, drug product, and method-of-use patents), and each patent has its own expiration dates.
If you share the NDA number or the exact label name/strength you’re looking at, I can point to the specific patent numbers and expiration timelines that correspond to that Orange Book listing.
What does “orange book patent” mean for Zelsuvmi, practically?
Orange Book patents are used to trigger Hatch-Waxman “patent certification” for generic and other follow-on applicants. If a patent is listed for the Zelsuvmi NDA, challengers must certify against it (for example, whether they claim the patent is expired, will expire on a certain date, or is invalid/unenforceable). This can lead to disputes and affects when a generic can be approved and marketed.

Why would someone search “Zelsuvmi Orange Book patent”?
People typically search for Zelsuvmi Orange Book patents to:
- estimate when generic competition could launch (based on patent expiry and exclusivity),
- see which patents might be challenged,
- understand whether any “use” patents (not just the active ingredient) are still in force,
- check how long exclusivity overlaps with patent life.
Quick next step
Send either:
- the Zelsuvmi NDA number, or
- a screenshot/text of the Orange Book “Patents” section you’re looking at, or
- the active ingredient and strength exactly as shown in the Orange Book,
and I’ll extract the patent(s) shown, summarize what type each one is (where that information is available), and report the expiration timing tied to that Orange Book entry.
