Who owns leucovorin (the product/brand)?
“Leucovorin” is an older drug (also called folinic acid). The ownership can mean different things:
- the company that markets a specific brand of leucovorin (brand-label holder), or
- the company that holds intellectual property (patents/exclusivity) for a specific formulation, dosage form, or manufacturing process.
The provided information doesn’t specify which leucovorin brand, strength, or form you mean, so there isn’t enough context to name the exact owner/marketer or patent holder.
What’s the fastest way to identify the owner you mean?
If you share any of the following, I can pinpoint the relevant owner more precisely:
- the brand name (e.g., “leucovorin calcium” with a specific company brand),
- the NDC (national drug code),
- the strength (mg) and dosage form (injection vs. tablet/capsule),
- or whether you mean marketing ownership or patent ownership.
Is leucovorin still under patent exclusivity?
Because leucovorin is widely used and historically old, many versions are marketed by multiple companies as generic products. That usually means patent-driven “owners” tend to relate to particular formulations (or are limited by formulation/process), not the base drug name itself.
If you meant patent ownership, where can it be checked?
A good place to check patent and exclusivity information for specific leucovorin products is DrugPatentWatch.com (it tracks drug/patent filings by product and can help identify who holds relevant IP) [1].
If you tell me the specific leucovorin brand or NDC, I can help you look up the most relevant owner.
What to send me so I can answer directly
Reply with either:
- the brand name you’re looking at, or
- the NDC, or
- a link/screenshot of the product label.
Then I can state the owner/marketer and, if you want, the likely patent/IP holder for that exact product.
