As to the cost of the system to the public, I don’t see how it could be calculated, for it consists not merely of the licence fees, but also of the loss resulting from the stamping out of competition, which would cheapen production and, in most cases, lead to improvement. My great objection to our indiscriminate Patent system is, that it is scarcely possible to strike out in any new direction without coming in contact with Patents for schemes so crudely developed as to receive little or no acceptance from the public, but which, nevertheless, block the road to really practical improvement. Nothing, I think, can be more monstrous than that so grave a matter as a monopoly should be granted to any person for anything without inquiry either as to private merit or public policy—in fact, merely for the asking and the paying. Amongst other evils of this indiscriminate system is that the majority of Patents granted are bad, and yet such is the dread of litigation, that people submit to a Patent they know to be bad rather than involve themselves in the trouble and expense of resisting it. So that a bad Patent, in general, answers just as well as a good one. One of the most common arguments in favour of Patents is, that they are necessary to protect the poor inventor, but it is manufacturers and capitalists, and not working men, who make great profits by Patents, and that, too, in a degree which has no reference either to the merit of the inventor or the importance of the invention. One rarely hears of a working man making a good thing of a Patent. If he hits upon a good idea he has seldom the means of developing it to a marketable form, and he generally sells it for a trifle to a capitalist, who brings it to maturity and profits by it. He could sell his idea just as well without any Patent-Law. May 13, 1869. FROM ANOTHER HIGH PRACTICAL AUTHORITY, LIKEWISE A NOTABLE INVENTOR.
