John Catron,
Troy Iron and Nail Factory v. Odiorne…
“ Henry Burden obtained a patent, in 1840, for a machine to make hook-headed spikes. He applied for the patent on the 18th of April, 1839. It was assigned to the Tory Iron and Nail Company, who filed a bill against the Odiornes, to enjoin them, and for an account for using a machine to make similar spikes; and which machine, it is alleged, infringed the monopoly secured to Burden, by his patent of 1840. ”
