Samuel Freeman Miller,
Hammond v. Mason and Hamlin Organ Company…
“ While it is, perhaps, not necessary to decide whether in any case a sale of an invention which is never patented carries with it any thing of value, we are of opinion that the rights growing out of an invention may be sold, and that in the present case the sale, with the right to use it in connection with the existing patent and its reissues or renewals, protects defendants from liability as infringers. ”
