    "Be it known that I, HANS HOHNER, a citizen of the German Empire, residing at Trossingen, lViirtemberg, Germany, have invented certain new and useful improvements in Mouth-Harmonicas; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same."

  • The patent act of 1790 established the rules for submitting a patent application. Each application had to be submitted with specifications, a patent drawing, and if possible a model of the invention. Eventually, models were no longer required.

    The National Archives holds nearly three million patent case files from 1836-1956.
