“The unlimited power given by a monopoly to an inventor has this practical effect at present, that when an invention has been made the subject of a Patent, everybody shrinks from it, everybody runs away from it, everybody avoids it as an unlimited evil, because the person who has the monopoly can subject you to a most expensive prosecution, and can charge you a most inconvenient sum for what you have done, and can punish you in every way for having touched his invention.” Mr. Grove says it is natural that people should yield to the holder of the Patent, for, if “He has a letter from a patentee saying, ‘You are infringing my Patent;’ I do not believe that the tradesman would go to the expense of litigation with the patentee, and for this reason, it is the patentee’s interest to give a very large sum of money to support his Patent. His Patent, although for a very trivial thing, may, taking the vast extent of sale, be a very lucrative affair, and therefore it is worth his while to lay out a large sum of money to support his Patent. It is not worth the while of the opponent, because he has only a little stock which affects him; the patentee has his whole interest consolidated in the Patent. All those who might oppose the Patent are a scattered body, namely, the public generally, not one of whom has any strong interest in opposing the Patent; and I believe that that has been very much worked by patentees, particularly in a small and comparatively frivolous and perhaps an all but useless invention. The public is a scattered body, not one of whom has sufficient interest to meet with equal force the patentee.” Mr. Platt, M.P., presents the following case, to show how unprincipled people use the power which the law gives them, and how, even with a good case, if they but knew it to be so, people in business are led to succumb to extortion:—
