To be newin the sense of the aet it must be the prôdùct of original thought or inventive skill, and not a mere formai or meohan- ical change of what was old and well known; but the effect produced by the change is often an appropriate though nota oontroUing consideration in determining th« char ac ter of the change itself . " �Tested by the mie of utility here euggested, this record abundantly shows that the device in question bas been ac- cepted by the public to an extent which bas hardly heretofore followed the most successful inventions. Its utility must be considered as a conceded fact. From what has already been developed, it is clear that it has made possible the cultiva- tion of the extensive praries of the west, the pampas of BrazU, and the steppes of Eussia, where, before the introduction of this cheap mode of fencing, it was imposible ; and it has, even to agreat extent, already superseded the uSeof wooden fonces in the timberted portion of the country; and the question i&, to whom but these inventors is. the public indebted for this widely-useful device ? > �The third objection, that the re-issues are invàlid, involves a consideration of the original patents in their ord^r, and those patents as they now stand amended and re-issued. �The Hunt patent of July 23, 1867, was fôr his method of "providing the wircs of a wire fence with a series of spui wheels." ^ The re-issued is "foir "à fence wire prbvided with spurs for the pùrpose specified." In other words, what Hurit at first claimed as his invention, and obtained a patent for, was his special mode of arming the wires of a wire fence with spur whfiels or barbs ; but in his re-issue he claimed as his invention a barbed fence wire as a new article of manufac- ture, and it is argued that while he may have been the first to place hia particular kind of spur or barb on a fence wire, and may bave been entitled to a patent for such specifie device, yet he nowhere claimed to be the inventer of barbed or spurred wire as such, and therefore his broad claim in the re-issue should not have been allowed and cannot be aus- tained. ����
