Who currently owns the leucovorin (folinic acid) patents?
Based on the information provided, there isn’t enough detail to identify a specific “leucovorin patent” owner. “Leucovorin” (also known as folinic acid) has multiple related patents and ownership can vary by jurisdiction and by patent family (for the original compound, manufacturing process, or specific formulations).
Which specific patent do you mean?
To determine who owns it, you need at least one of the following:
- the patent number (e.g., US…, EP…, WO…)
- the assignee/holder named on the patent document
- the active ingredient version (e.g., calcium folinate vs. disodium folinate) and dosage form
- the country/region where you’re looking (US, Europe, etc.)
How to find the patent owner quickly
If you share a patent number or jurisdiction, I can pinpoint the assignee/owner from the patent record. If you don’t have the number, the fastest path is to look up “folinic acid / leucovorin” patents in the relevant country’s patent database and then match the specific claim set you care about.
If you want, tell me your target and I’ll identify the owner
Reply with any of these:
- the patent number you saw
- where you saw it (site, article, label, or filing)
- the drug name wording (leucovorin vs folinic acid, and whether it’s calcium folinate or disodium folinate)
Then I can tell you who owns that specific patent.
