When does ultomiris patent expire?

When does the Ultomiris (ravulizumab) patent expire?

I can’t give an exact “patent expires on” date for Ultomiris from the information available here. Patent life depends on multiple filings (primary patent, continuation patents, method vs. composition claims) and the applicable term adjustments, plus any patent-for-patent litigation or settlements that can affect market exclusivity.

What to check to find the exact expiry date

To get the precise expiry timing, you typically need the specific patent numbers covering Ultomiris (ravulizumab), then apply:
- Patent term (generally tied to earliest non-provisional filing and normal USPTO term rules)
- Any patent term adjustments (PTA) granted by the USPTO
- Any patent term extensions (PTE), when applicable
- Whether exclusivity (e.g., biologics exclusivity) runs longer than the last composition claim
- If a competitor’s biosimilar application has been timed around the listed “Orange Book” protections (for biologics, the “Purple Book” can also be relevant)
