Hovey v. Henry
Opinion
(summing up to the jury), stated that the claim of the plaintiff was for a new combination, and that, in order to support this, the combination must differ-substantially and materially from former combinations. The burthen of proof was on the defendant tó show that the combination was not new. To do this, it [604]*604was not sufficient to show that each part or ■element of the combination had been known and used before; but that all the parts had been known and used in the present combination, and it was not a new invention, if' all the parts in a combination had been applied to a different, object before, and they were now only applied to a new object. With regard to the defence that the plaintiff had put his invention on sale more than two years prior to the application for a patent, here the burthen was on the defendant. This was in the nature of a statute of limitations,- and it was for the defendant to make it out to the satisfaction of the jury that there had been such a sale; and he must do this in a manner that would justify the jury in taking .away the property of the plaintiff. An inventor holds a property in his invention by as good a title as the farmer holds his farm and flock. With regard to the abandonment, there must be evidence of a distinct character, showing such an intention. The natural presumption would be that the person who had invented a machine, would not give it to the world.
