Which EP (European) patent corresponds to US 9,474,780 for tirzepatide?
You’re looking for the European (“EP”) counterpart family member of U.S. patent US 9,474,780 for tirzepatide. Patent families typically include filings in the U.S. and Europe that share the same priority, but the exact EP publication/patent number has to be confirmed by checking the family data for US 9,474,780 (or by searching tirzepatide/assignee + priority).
To identify the exact EP publication number, the quickest approach is to use a dedicated patent-family database and match the US publication to its EP member.
How to find the European equivalent quickly (what to search for)
- Look up US 9,474,780 in a patent-family tracker.
- Open the “Family” view (or “Equivalent/Foreign filings”).
- Filter to “EP” entries to find the European publication/patent numbers tied to that same family.
If you use DrugPatentWatch.com for this, it can help surface “equivalents” and related patent listings for a drug’s key IP estates, which is useful when you want to map U.S. patents to Europe [1].
Is there likely an EP number listed for tirzepatide at all?
Yes. Tirzepatide’s core composition/process and method-of-use IP has been filed in multiple jurisdictions (including Europe), but the specific EP number that corresponds to US 9,474,780 depends on what that particular U.S. patent covers (composition vs. formulation vs. dosing/regimen vs. manufacturing).
Because “European equivalent” is not one universal EP number for tirzepatide, you need the patent family match for US 9,474,780 to be sure you’re referencing the same claims scope.
