Does the Ocrevus patent US7799900 expire in 2028?

When does Ocrevus (ocrelizumab) exclusivity end in the US—patent vs. exclusivity

Drug exclusivity in the US can extend beyond the date a specific patent expires. A drug may have:
- Patent expiration (e.g., for US7799900), which blocks certain generic/biosimilar launch attempts tied to that patent; and
- FDA exclusivity or reference-product protection periods that can delay biosimilar approval/marketing even after some patents expire.

If you are trying to pin down the first date a biosimilar could launch, you typically need to check both the relevant listed patents and any remaining exclusivity periods.

Why do patent-expiration dates sometimes differ (and what to check for US7799900)

Exact launch timing can shift because of:
- Patent term adjustments or extensions
- Related continuation/divisional patents
- Orange Book listing context (for the specific product/formulation)
- Litigation outcomes (if any parties challenge the patent or argue non-infringement/invalidity)
