Ward Hunt, Eunson v. Dodge — Opinion of the Court
“ That the purchase of the machine was made from an infringer, and a wrong done, is true. When informed of the offence, the purchaser at once corrected the evil by purchasing the entire right of the patentees for the county where his machine was then used, and where it has since been used. This was equivalent to an original lawful purchase or manufacture of the machine. ”
