tlbe Conservative * that cnso ( Hotchkiss v. Greenwood , 11 Howard , 248) ) that hnd the court found mechanical skill or ingenuity present , even in the means of attaching the knob to the shank , to that extent the patent would have been upheld , but , as it was reduced , at most , mi'reJy to the selection of materials , the patent was found in valid for want of novelty. On the other hand , in the cose of Col gate v. Western Union Telegraph Co. (15 ( Elatchf. , 805) ) , Judge Blatchford held that a patent for a metallic wire covered with gutta-percha , based upon the dis covery of the fact that gutta-percha is a non-conductor of electricity , was prop erly the subject of patent protection under the statute , though covered wire , as a protection against rust , existed be fore the patent. "Wo make the bald statement , and wo challenge its contradiction in our federal constitution , in the history of our acts of congress in respect to pat ents , or in the acts of congress them selves , that , bo the thing patented new and usrful and let such a thing come fairly within the classes named in the statute , i. c. , "any new and useful art , machine , manufacture , or composition of matter , or any new and useful im provement thereof , " the patent granted for same is one contemplated by law ; and puch o patent should not bo declared invalid because , forsooth , some chan- celor , after the thing has been disclosed , turning pro ( em. into a metaphysician , finds the subject of the grant in volved , by the test of metaphysics , but mechanical skill. Call it by what name you will ( like the rose , by any other name it will be as sweet to the patentee ) if it respond to the above statutory requirements , it is a thing "invented" brought to light by the inventor , as such has become a part of the stock of useful knowledge , and as such is entitled to protection under our patent laws , as they exist today , and as they have existed since the first act of congress on the subject. Iii nothing that wo have said do wo mean to charge that the courts have been wrong in all cases in which they declared patents invalid for want of novelty. No doubt , in many such cases the courts have arrived at correct con clusions and by correct methods of rea soning ; while in others their conclusions were correct though the' reasons for their conclusions may not have been sound. But we do mean to say that in all such cases in which patents have been justly declared invalid the judg ments were just and lawful , no matter what the reasons assigned for the judg ments may have been , not because the subjects of the patent were the result of mechanical skill , but because they were lacking either in novelty or utility. Copyrights. Our copyright statutes rest upon pre cisely the same foundation as our stat utes in respect to patents , f. e. , that con gress shall have power "to promote the progress of science and useful arts , by securing for limited times to authors and inventors the exclusive right to their re spective writings and discoveries , " yet the copyright laws , interpreted by the courts with that same liberality which lias been evidenced by the supreme court in dealing with the patent laws , as expressed in its opinion by Chief Justice Marshall , supra , make no distinction be tween the humble compiler of a direc tory , the less deserving author of the "dime novel , " and the genius of the poet , but recognizing each as an "author , " deal out even justice to all. It might as well bo said , and with quite as much reason in the constitution and statutes , that a chancelor could sit in judgment upon the literary merit of a book , the contents of which are ad mittedly new and useful , to determine whether or not the holder of the .copy right was an "author" that his bnok tiad enough literary merit to be consist ent with the dignity of "authorship" as to say that under our patent statutes , as they exist , a chancelor , in a case where the patented thing is admittedly new and useful , is to pass upon the meta physical question as to whether or not the subject of the patent rises to the dignity of an invention or involves merely mechanical skill. "We submit that reason and the opin ions of the most learned chancelors are with us in our contention ; that the only safe guide to follow in these cases is to take the law as we find it in the statute , and , imbued with the history of that law and its tnie spirit as expressed by those nearest the fountninliPad , and by those who have followed and by their writings rhown themselves to be most thoroughly conversant with its history and the reason for its existence , and when we find that the subject of the patent can fairly be said to be or relate to "ani/ art , machine , manufacture , or composition of matter or any improve ment thereof" and that it is new and useful , no matter how simple , then to uphold the patent. Mr. Curtis ( Curtis on Patents,4th ed. , ยง 8.i ) saw this very clearly ; he says : "It may be doubted , whether all the different forms of stating or investiga ting the question of sufficiency of inven tion are anything more than different modes of conducting the inquiry , whether the particular subject of a pat ent possesses the statute requisites of nov elty and utility , both of which qualities must bo found uniting in it. " This , after all , is the principle recog nized by the supreme court in the barbed wire cases (148 ( U. S. , 275) ) by the able opinion of Mr. Justice Brown , and it is the same principle which has been recog nized as correct and applied by many ot the most learned judges of our country and of our day , in many cases. We think we see in some of these more recent decisions a recognition of the principles which are thus stated by Chief Justice Marshall in Grant v. Raymond mend and which will bear repetition here : "To promote the progress of use ful arts , is the interest and policy of every enlightened government. It en tered into the views of the framers of our constitution , and the power to 'pro mote the progress of science and useful arts , by securing for limited times , to authors and inventors , the exclusive right to their respective writings and discoveries' is among those expressly given to congress. This subject was among the first which followed the or ganization of our government. It was taken up by the first congress at its second session , and an act was passed authorizing a patent to bo issued to the inventor of any useful art , etc. , on his petition , 'granting to such petitioners , liis heirs , administrators , or assigns , for any term not exceeding fourteen years , the solo and exclusive right and liberty of making , using , and vending to others to be used the said invention or dis covery. ' The law further declares that the patent 'shall be good and available to the grantee or grantees , by force of this act , to all and every intent and pur pose herein contained. ' The amenda tory act , of 1793 , contains the same language and it cannot bo doubted that the settled purpose of the United States has ever been , and continues to be , to confer on the authors of useful inven tions an exclusive right in their inven tions for the time mentioned in their patent. It is the reward stipulated for the advantages derived by the public for the exertions of the individual and is intended as a stimulus to these exer tions. The laws which are passed to give effect to this purpose ought , we think , to be construed in the spirit in which they have been made , and to execute the contract fairly on the part of the United States , where the full ben efit has been actually received if tin's can be done without transcending the intention of the statutes , or countenan cing acts which are fraudulent or may prove mischievous. "Tho public yields nothing which it has not agreed to yield it receives all which it contracted to receive ; the full benefit of the discovery , after its enjoy ment by the discoverer for fourteen years , is preserved ; and for his exclusive en joyment of it during that time the pub lic faith is pledged. That sense of jus tice and of right , which all feel , pleads strongly against depriving the inventor of the compensation thus solemnly promised. " Justice . How just and equitable these princi ples are , and what a safe guide do we not find in them 1 What harm can come of following these principles , even as applied to what the courts may call "a narrow inven-
