The project of law to repeal the Act of 1817 for granting exclusive rights on inventions and improvements of objects of art and industry, has given general satisfaction in four Committees of the House, and many have received it enthusiastically. By introducing this Bill, Government has satisfied a desire which of late was frequently manifested by members of the House. The memorial of explanation, with its vouchers, gives full particulars of the objections raised against the Patent system. Most members, in fact, simply gave their adhesion in substance, without considering it necessary to “motivate” their opinion. A few Members of one of the Committees did not agree with absolute repeal, and even held such a measure to be at variance with justice and equity; they recognised the law of 1817 to be defective and in many cases impracticable; they granted that when a reform might be arrived at “Patents of admission” ought not to remain in force; but they did not see why, on account of the insufficiency of the law in this country, “Patents for invention” should be abolished as well. There are a good many industrial inventions which cost the originator vast mental labour, sometimes even heavy pecuniary sacrifice. By means of his invention he renders society a service which entitles him to enjoy, for a fixed period at least, the exclusive benefit of bringing it into operation. Should this benefit be denied him, it would be but fair that the State should give him a reward; this, however, is subject to difficulties of a peculiar nature. The opinion that the repeal of the law would leave intellectual property altogether unprotected, may be refuted by the fact that the principle of intellectual property cannot possibly form the basis for a Patent-Law. Although it was emphatically proclaimed in the French Legislature of the first years subsequent to the Revolution of 1789, it will not stand the test of sound criticism. Could right of property be admitted in this case, it ought to be permanent, and not temporary. Yet no Legislature ever dared to extend the so-called right, even for the inventor’s lifetime; the terms were generally ten, twelve, fifteen, and, at most, twenty years. Another circumstance, which is in downright contradiction with the notion of right of property, is the fact that everywhere Patents are granted only on payment of a certain sum. If Patents are to be defended at all, better try to do it on a principle of utility. Some appearances are in favour of the plea that anticipation of reward and pecuniary benefit originates useful inventions; but pecuniary experience has taught that although every now and then this may be the case, still the very existence of a strict Patent-Law, is, on the whole, a decided hindrance to industry; that the inventor’s benefit from his Patent is, in most instances, but doubtful, whereas by doing away with this artificial encouragement, inventions will not, on this account, remain in the bud undeveloped.
