Patent-right must not be confounded with Copyright. The latter stands on perfectly different grounds, and can be advocated and upheld, as he (Mr. Macfie) himself does, in perfect consistency with disfavour for the former. There can be no rival claimant to the authorship of any particular book; many persons may honestly and indisputably claim originality in an invention. The true similarity between these two subjects of privilege is not between the book and the invention or machine, but the book and the specification of the invention. When you buy a Murray’s handbook, a book on medicine, or a commercial guide, you are at liberty to act on information you find in it, and to travel, trade, or prescribe, according to the directions you find there. But mark the contrast in what Patent-Law creates. When you buy a specification, you know it tells only of certain things that you are not at liberty to do. Lastly: I acknowledge that it is legitimate to legislate with a view to promote or protect trade. The interference, however, which is now wanted is not a return to the old protective system of discriminative duties, but the clearing away of evil laws, and especially deliverance from the bondage and wrongs involved in Patent monopolies. For the origin of our definite Patent legislation we go back to the famous statute of James I. of England. At that time the people of this kingdom were in a state somewhat resembling our present state. They were desirous to extend trade and introduce new arts and manufactures. Parliament was powerful and hated monopolies, under which the people had been writhing. These it reprobated in the spirit of the jurists of antiquity. While by that statute it swept away all other monopolies, it permitted, or tolerated, that the Crown should grant the exceptional privilege for “the sole working or making of any manner of new manufactures within this realm, to the true and first inventor and inventors of such manufactures, which others at the time of making such Letters Patent and grants shall not use, so as also they be not contrary to the law nor mischievous to the State, by raising prices of commodities at home or hurt of trade or generally inconvenient.”
