Reduction of Inventions to Practice

Inventions to be patentable must be reduced to practice and embodied in some distinct machinery or composition of matter that will work and accomplish its intended purpose. The mental process of the inventor must be complete and brought to a point where invention ceases and construction may begin. This law does not require that an inventor develop his discovery to the highest degree of perfection, but he must describe his method with sufficient clearness and precision to enable those skilled in the matter to understand what the discovery is and point out a practicable way of putting it into operation. It is not the object of these laws to grant a monopoly for every trifling device, every shadow of a shade of an idea which would naturally spontaneously occur to any skilled mechanic or operator in the ordinary process of manufacture.
