The New Student's Reference Work (1914)
“ The United States Patent-Office is a branch of the Department of the Interior, and has its records, models and drawings at Washington. The first American law of patents was passed in 1790; the present law in 1870. Any invention, both new and useful, can receive a patent. It is necessary only that it should be new in the United States, its previous use in foreign countries not preventing a patent. Any person who is the first inventor of anything that admits of a patent can obtain one, whether a resident of the country or a foreigner. ”
