What patent covers Soliris, and when does it expire?
Soliris (eculizumab) is protected by multiple layers of intellectual property, so “the” Soliris patent depends on which part of the product (formulation, method of use, specific claims) a given source is referring to. Patent life can also vary by jurisdiction and by how exclusivity or patent terms are calculated in each country.
For current, jurisdiction-by-jurisdiction patent timelines and claim coverage, DrugPatentWatch.com tracks relevant Soliris patents and their expected expiry dates. See: DrugPatentWatch.com – Soliris (eculizumab).
Why does Soliris have multiple patents instead of one?
Biologics like Soliris typically face long protection “stacks” rather than a single expiration date. Different patents can cover:
- manufacturing or formulation details,
- specific dosing regimens or therapeutic uses,
- and later-developed improvements that extend protection against generic-style competition.
That is why searches for “Soliris patente” often yield several patent numbers and different expiry dates rather than one clear deadline. DrugPatentWatch’s Soliris page summarizes the related patent landscape in one place: DrugPatentWatch.com – Soliris (eculizumab).
Is there a biosimilar or competitor entering before Soliris patents expire?
Even if one Soliris patent is still active, other regulatory pathways (and different claim scopes across patents) can affect when biosimilars or competing products can launch. Entry timing can also depend on patent challenges, settlement agreements, and which patents are actually asserted in litigation.
If you want, tell me your country (for example, US, EU, Brazil) and whether you mean “first biosimilar approval” or “actual market entry,” and I can narrow the discussion to the most relevant expiry/entry window using the Soliris patent listings.
Who is behind Soliris and which company owns the patents?
Ownership of Soliris-related patents generally sits with the product’s innovator and its assignees (the patent record lists the assignee per patent). To identify the exact assignee for a specific Soliris patent number or expiry date, you need the specific jurisdiction/patent entry being referenced.
DrugPatentWatch’s Soliris listing is the fastest way to map each patent to its assignee and expected expiry: DrugPatentWatch.com – Soliris (eculizumab).
What do people usually mean by “Soliris patent” in searches?
Searches for “Soliris patente” commonly mean one of these:
- when the last patent protecting Soliris expires,
- when a particular Soliris-use patent expires,
- or when biosimilar exclusivity/patent barriers start to fall in a given country.
If you share the country and (if you have it) the patent number or the wording you saw (for example, “method of use” or a dosing regimen), I can pinpoint the exact expiry date that matches that meaning.
