Besides, it is not sufficient to make up one’s mind to make an invention capable of being patented; such proceedings lead to a success in the most rare cases. The most important discoveries have proceeded, on the contrary, from those who thoughtfully prosecute their regular avocations. The fear that with abolition of Patents the ingenuity of mankind would slacken, we cannot share, because the germ of progress is embodied in human nature, and because the joy over an invention made, and the satisfaction felt at a new discovery, in themselves are powerful impulses for the employment of energies in such directions. A strong proof of the correctness of this assertion the men of science furnish, whom we have to thank for the most important discoveries, in so far as the application of physical and chemical laws to industry are concerned—which have been always handed over immediately to the public with the utmost liberality. Others have based their inventions on such laws, and managed to acquire for this one or that other a Patent, and thus, to their own advantage and to the cost of the public, made an invasion of territory hardly legitimately theirs. They reaped where others had sowed. Let us take, for instance, all the lighting apparatuses during the last twenty-five years. The different lamp contrivances during this period for which Patents have been granted by the industrial States of Europe will number several hundreds. Now, if we sift the matter, we will find that all these patented combinations are simply variations of a principle which Berzelius established and applied to his spirit-lamp. Similar is the experience with the invention of Bunsen, who reduced the costs of the electric battery considerably, by applying a hard sort of coke in place of the platinum in Grove’s Battery. In a still higher degree has Morse acted meritoriously. It is true, Morse, in consideration of the signal importance of his invention, has received a public reward in the shape of money, and this mode of acknowledging real merit in the province of inventions recommends itself for adoption even in individual States. After the abolition of Patents, apart from such acknowledgments as aforesaid, very soon associations of the various interested parties who, by each discovery, would be equally benefited, will be formed for the purpose of rewarding new inventions made in accordance with indicated problems, the solution of which may be felt to be most important to them. For State rewards only such inventions should be taken cognizance of as, according to their nature, cannot be kept secret, and are not of a kind that will ensure to the inventor an adequate reward by his own use of them.
