“ Upon the American view, a patent is a compact made with the inventor to induce him to disclose his invention for the public benefit; as a reward for which he receives an exclusive privilege which is in the nature of property. As respects many important inventions, the privilege would have little value if not good against Government, for the reason that the thing is only useful in Government business. What would be the worth of a patent for articles useful only in the army and navy, for a revenue or postage stamp, or the like, if Government might use the invention free? ”
