To an argument which has repeatedly been urged—_i.e._, that the granting a temporary exclusive right is indispensable (so as to secure for the meritorious inventor a reward adequate to the mental labour and money expended, as well as risk incurred, in order that there be no lack of encouragement to the inventive genius)—the objection may be raised that the remarkably developed system of communication and conveyance now-a-days, which has opened a wide field to real merit, and enables industrial men promptly to reap all benefit of production by means of enlarged outlets for their articles, will, generally speaking, bring those who know how to avail themselves before others of useful inventions to such an extent ahead of their competitors, that, even where no permanent privilege is longer admissible, they will make sure of a temporary extra profit, in proportion to the service rendered to the public. It is, in fact, in the peculiar advantage produced by the early bringing into operation of a fresh suggestion of their minds, that the remuneration of those lies, who, through cleverness and steadiness of purpose, succeed in satisfying existing wants in a manner less expensive and superior to what previously was the case, and notwithstanding do not obtain any monopoly. Not of less account are the practical impediments which stand in the way of every effort to bring about an improvement of the Patent-Law. It is generally admitted by the promoters of Patent-right, that the system of inquiry or examination, as it is now working in Prussia, cannot possibly remain in its present condition, and the experienced officers appointed to decide upon Patent matters and make the necessary inquiries, unanimously confirm that opinion. Though provided with relatively excellent means of ascertaining, the Prussian Technical Committee for Industry had to acknowledge as early as 1853 (_Vide_ Prussian Trade Archives of 1854, Vol. ii., page 173, ff.) that the question whether an invention submitted for being patented might not perchance already have been made or brought into operation elsewhere, was almost an unsolvable one. Since then, inventions have augmented yearly in steadily increasing proportion. The main difficulty, however, not only rests in the impossibility of mastering the matter submitted, but equally so with the upholding of firm principles relating to the criterion of originality. If the inquiry do not altogether deviate from its primitive object by patenting any and every innovation in construction, form, or execution, which is presented, we fall into such uncertainty when sifting actual inventions from the mass of things which are not to be considered as undeniable improvements—owing to the continually increasing and diversified combinations of generally known elements or material and altered constructions or modes of application—that it is hardly possible not to be occasionally chargeable with injustice.
