United States District Court for the Southern District of New York, Valvoline Oil Co. v. Havoline Oil Co… (1913)
“ If I did not know anything about motor oils, and some one told me to buy "Valvoline," the word "valve" would be impressed on my mind. True, "Valvoline" has been held not to be descriptive, yet just as the English court held [4] that the word meant valve oil, so would I, as a purchaser, think that it had something to do with valves. Of course, I would soon discover that "Valvoline" had a wider meaning, but when I heard "Havoline" I would think that it was some coined word or perhaps some technical term, and it would not suggest "Valvoline" to me. ”
