When does the eculizumab patent expire if it was filed in 1996?
The information needed to answer “eculizumab patent 1996” accurately is the specific patent number (or at least the applicant/assignee and jurisdiction, such as US vs. EP). “Eculizumab” is associated with multiple patents filed and granted across different countries and years, and different patents can expire on different schedules.
To verify the exact patent expiry tied to a 1996 filing, you need to identify which 1996 eculizumab patent you mean (for example, a primary composition-of-matter patent vs. a later formulation, use, or method patent).
Which specific eculizumab patent was filed in 1996?
Eculizumab (Soliris) has had a long, multi-patent life, so “patent 1996” could refer to:
- the first composition-of-matter family in a given jurisdiction,
- a continuation/divisional in the same family,
- or a separate patent covering an indication, dosing, or manufacturing detail.
If you share the patent number (e.g., “USxxxxxxx”) or jurisdiction, I can pinpoint the expiry date for that exact filing.
Where can I check the eculizumab patent filed in 1996?

Is the 1996 date about the active substance patent or exclusivity?
In many cases, the earliest composition-of-matter filing date drives baseline patent term, but regulatory exclusivity (and other patent layers) can extend market protection in practice. The “real-world” end date for competition can depend on:
- whether other patents in the family are still in force,
- whether any additional exclusivities apply in that country,
- and whether litigation affects launch timing.
What I need from you to give the exact expiry date
Reply with any one of the following, and I’ll map it to the correct expiry:
- the patent number (US/EP/WO, etc.), or
- the patent link, or
- the name of the patent family/assignee from the 1996 reference.
