Who invented Tylenol?
Tylenol [acetaminophen] was discovered by David W. Young, a graduate of Covington Latin School and the University of Kentucky, while working on chemical patents at Standard Oil of Ohio in Cleveland, Ohio. – Wikipedia
When acetaminophen was discovered, it was thought to be useless. Therefore, the patent went with no problem to David Young himself, rather than to the University employer. Sucks for them. Young later discovered its use and sold the patent to Johnson & Johnson, who marketed the drug as Tylenol in 1955, first to children, then to the widespread marketplace.
Tylenol is one of those brands that has become so household in nature that it has lost its brand value (in monetary terms) – the name becomes a common term for the drug and has little footing when it comes to brand name infringement.
Arieanna fact: I have consumed more than 500 Tylenol this year alone (moderate guess).
