HOLLAND. I have before me a series of valuable illustrative documents printed by the Government of the Netherlands, which are too long to introduce here. The movement for abolishing Patents in that country, already referred to on pages 196-230, was consummated by a striking majority, in the First Chamber, of no less than 29 to 1; the abolition to take effect from 1st January next, existing rights, of course, to be respected. ON PERPETUITY OF PATENT-RIGHT. The following observations, abridged from a review, by M. Aug. Boudron, of M. le Hardy de Beaulieu’s _La Propriété et sa Rente_, are from the _Journal des Economistes_ for May:— The author assimilates the inventor’s privileges to proprietorship of a field. Nevertheless there is a fundamental difference between the two kinds of property. Independently of State privileges, the originator of a discovery may use it as his own, and even to the exclusion of all others, provided he keep it secret, so that he shall have no competitor to encounter; whereas the owner of a field, if he is deprived of his right, loses all. The advantages of an invention may be enjoyed simultaneously by many persons; the produce of a field by one only. Now for a difference of importance affecting the interests of the public. Give the possessor of a field his right in perpetuity, and you have circumstances the most favourable for its yielding all the produce which it can. Not so with the privilege of an inventor, for it essentially consists in hindering others from bringing the methods or materials that are patented into use. From the time of invention and first _exploitation_ the privilege is an obstacle; it limits the amount of good that society would in its absence enjoy. What, then, is the motive of certain States in conceding this exclusive privilege?... The legislators who have created the right thought that there would in consequence be a larger number of useful inventions and improvements, and that, on the whole, society would be a greater gainer than if there were no Patents.... As there are innumerable instruments and processes for which Patents have been and might still be taken, there must, if perpetuity of privilege be granted, be a prodigious number of monopolies, and almost no operation could be performed, nothing done, without people being obliged to pay tribute to some privileged person. There would be a countless host of administrators like receivers of tolls and pontages, diminishing wealth in place of creating it; the world would soon produce too little to sustain the monopolists and their _employés_. We thus arrive at an impossibility. But conceive all this possible, and the world must yet miss a great number of inventions and improvements, that would under the system of perpetuity be prevented. This is seen by the obstacles which even privileges of limited duration throw in the way of new inventions. In actual practice progress is often attained only by the use of previous inventions.
