Stanley Matthews, Beedle v. Bennett — Opinion of the Court
“ The act of 1839, as has repeatedly been held, has no effect to invalidate a patent, unless there be proof of abandonment, or of a use of the invention for more than two years prior to the application for the patent. The only facts from which such an abandonment or dedication can be inferred are that Green, in June, 1861, put down a well at his house in Cortland, New York ”
