“ We are clearly of opinion that a change in the mode of cooking the meat from broiling, roasting, or steaming to boiling, all the other parts of the process remaining unchanged, cannot be called invention, and does not entitle the party who suggests the change to a patent for the process. 'All improvement is not invention, and entitled to protection as such. ”

“ The second disclaimer of Wilson is a substantial admission that his patent only covers the process in which the boiling of the meat is one of the elements. That is to say, any one may pack cooked meat for transportation by compressing it while heated with cooking into air-tight hermetically sealed packages, so as to preserve it in its integrity and retain all its natural juices and nutritious qualities, substantially as set forth in the patent, and not infringe the patent, provided he does not cook the meat by boiling. ”

“ Thus to entitle it, it ought to be the product of some exercise of the inventive faculties, and it must involve something more than what is obvious to persons skilled in the art.' Pearce v. Mulford, 102 U.S. 112. ”
