What “Zelsuvmi” Orange Book patent listings are (and why people look them up)
The FDA’s Orange Book lists drug products with “patents” and “exclusivities” that affect when generic or biosimilar versions can be approved. For a given product, the listings typically include patent numbers, expiration dates, and whether the patent is tied to exclusivity blocking (for example, by use/approval or composition). This is the key reference point used when determining potential launch timing for follow-on manufacturers.
Which Orange Book patents are tied to Zelsuvmi?
To identify the exact Orange Book patent numbers and expiration dates for Zelsuvmi, you need the product’s specific Orange Book entry (product name + manufacturer/label strength). Zelsuvmi’s Orange Book listings can vary depending on the specific formulation and applicant/labeling details, and Orange Book entries are where the patent numbers and relevant expiration windows appear.
If you share the exact Zelsuvmi entry you mean (manufacturer name and/or strength), I can map it to the specific Orange Book patents and their stated expiration dates.
When does patent protection for Zelsuvmi expire, according to the Orange Book?
Patent “expiration” in the Orange Book depends on which listed patent you’re asking about, because different patents can expire at different times. Also, Orange Book exclusivity (not the same thing as a patent) can extend market protection even after a particular patent expires, depending on the exclusivity type.
For exact dates, the Orange Book listing for Zelsuvmi is the authoritative source.

Are there risks or confusion points when reading Orange Book patents?
Yes. Common pitfalls include:
- Mixing up Orange Book listings for different strengths or manufacturers.
- Confusing a listed “patent expiration date” with the end of all exclusivity protections.
- Assuming Orange Book listings alone fully predict generic launch timing; FDA approvals also depend on the applicant’s application pathway and whether patents are challenged or carved out.
