Who originally patented ivermectin?
Ivermectin was developed from a family of naturally occurring compounds (avermectins) made by the soil bacterium Streptomyces avermitilis. The major patent rights tied to ivermectin’s development in humans and animals are associated with the company that carried the program through discovery and commercialization—Merck (historically Merck & Co.).
Which company is most associated with ivermectin’s patents?
Merck is widely credited with the patent portfolio that enabled ivermectin’s large-scale commercialization, including the key uses that made it a standard antiparasitic drug for humans and animals.

Are “patented ivermectin” and “patented uses/formulations” the same?
No. Even when a molecule like ivermectin is first patented, later patents can cover specific therapeutic uses (such as particular indications), formulations, or combinations. That’s why multiple assignees/patent families can appear in public patent databases over time even if the original discovery/commercialization effort is associated with Merck.
What if you mean “who invented ivermectin,” not just “who holds patents”?
If you mean the people credited with discovery rather than the legal patent assignee, ivermectin’s breakthrough is commonly linked to research that led to the drug’s antiparasitic development, with major credit associated with the Merck-led program (and the broader scientific work on avermectins). However, patent “owners” (assignees) and “inventors” (named people) are two different fields on patent documents.
