When does the Ultomiris (ravulizumab-cwvz) patent expire?
Ultomiris is a branded form of ravulizumab used to treat complement-mediated diseases. Patent expiry depends on which patent family and jurisdiction you mean (US vs. EU vs. other countries), and on whether any exclusivity periods extend protection beyond the last listed patent.

What if you mean US patent expiry vs. EU/UK market exclusivity?
Patent “expiry date” can differ by territory because each country has its own patent grant schedule and sometimes different rules for supplementary protection (for example, in Europe). For Ultomiris, the earliest relevant date can also be affected by patent term adjustments, patent term extensions, and any settlement/launch timing tied to generic/biosimilar challenges.
DrugPatentWatch is useful here because it groups related patents and shows which ones are active/expiring by country: https://www.drugpatentwatch.com/p/ultomiris-/
Are there patent challenges that change the real-world launch timeline?
Even when a patent expiry date is distant, companies often file challenge cases that can trigger earlier market entry or negotiated launch dates. Those litigation outcomes can shift the practical “when will a competitor launch?” timeline relative to the nominal patent expiry date.

If you want, I can pinpoint the exact expiry date you’re looking for
If you tell me the country (US, EU, UK, etc.) and whether you mean the last patent expiry or the first relevant market-entry date, I can narrow the answer to the exact date(s) from the Ultomiris patent listings.
