    HEATON PENINSULAR BUTTON-FASTENER CO. v. SCHLOCHT-MEYER.
    (Circuit Court, S. D. Ohio, W. D.
    July 22, 1895.)
    No. 4,775.
    1. Pleading in Patent Cases—Pkofert of Patent—Demurrer to Bill.
    A bill containing this language, “All of which will more fully appear by the said letters patent, or by a copy of the same duly certified from the records of the patent office, and in this court to be produced as your honors may direct,” makes formal profort of the patent, so that it may be considered on demurrer to the bill. 1
    
      2. Same—Infringement Suits—Judicial Notice of Prior Art.
    In determining the validity of a patent on demurrer to the hill, courts will take judicial notice of matters of common knowledge relating to the state of tile art; hut the judge must he careful to distinguish between his own special knowledge and what is strictly within the field of common knowledge, and the matter must be so plain as to leave no room for doubt.
    3. Same—Description of Prior Art—Estoppel.
    The description in the specification of the existing state of the art bears upon the construction of the patent, and is a limitation of the grant. It forms the representations upon which the grant is obtained, and the patentee is estopped to say that such representations were incorrect.
    4. Same—Button-Fastening Staples.
    The Vinton and the Prentice, patents, Nos. 324,053 and 451,070, respectively. hot! for improvements in button-fastening staples, held void, on demurrer, for want of invention.
    This was a bill by the Heaton Peninsular Button-Fastener Company against Schloehtmeyer, for infringement of two patents for improvements in button-fastening staples.
    Jas. II. Lmge, Odin B. Roberts, Gardner Perry, and S. L. Swartz, for complainant.
    Taggart, Knappen & Denison, for respondent.
   SAGE, District Judge.

The bill is for an injunction and account against defendant as an infringer of two patents, owned by complainant, for button-fastening staples,—the first being No. 324,053. to John H. Vinton, August 11, 1885, and the second No. 451,070, to George W. Prentice, January 26, 1891.

The defendant demurs upon the grounds r First, that it is apparent upon the face of the letters patent referred to, that the two inventions and improvements described and claimed therein cannot be used conjointly in the same structure; second, that the Vinton I atent is invalid for the reason that the improvements described and claimed did not, in view of the static' of the art within common knowledge, and of which the court will take judicial notice;, constitute; patentable invention; and, third, that the Prentice patent is invalid, for the same reason. The first ground of demurrer wa.s abandoned upon the argument, and upon the averments of the bill was untenable. That a demurrer to a bill for infringement will be sustained in any c.ase where it is apparent to the court that the alleged improvement does not involve patentable; invention, although the hill allege;» novelty and utility, is well-establishe;d. The demurrer admits only those facts which are well pleaded, and an allegation of fact in one part of the bill, which by inspection of the entire bill appears to be untrue, cannot be said to be well pleaded.

In Wollensak v. Reiher, 135 U. S. 96, 5 Sup. Ct. 1137, the supreme court held, upon inspection of the original and the reissued patent, and upon demurrer to the bill, that the original specification was not: insufiicie'nt or defective, and that the sole object of the reissue was to enlarge the claim, and sustained the demurrer, notwithstanding the avenan ent of the bill that the original patent was inoperative or invalid by reason of an insufficient or defective specification, which insufficiency or defect bad arisen through inadvertence, accident, or mistake.

In Richards v. Elevator Co., decided by the supreme court of the; United States, May 20, 1893, and reported in 71 O. G. 1456, 15 Sup. Ct. 831, Mr. Justice Brown, dedivering the opinion of the court, said that:

“While; patent cases are usually disposed of upón bill, answer, and proof, there is no objection, if the jaitent bo manifestly Invalid npon its face, to the point being raised on demurrer, and the case being determined upon the issue so formed.”

The patent in that case was for a grain-transferring apparatus, and the claims were fpr combinations which the court held to be; for a puro aggregation of old elements. It was not claimed that -there was any novelty in any one of the elements of the combination. The court said (hat they were all perfectly well known, and, if not known in the combination described, were known in combinations so analogous that the court was at liberty to judge of itself wind her (here was any invention in using them in the exact combination claimed. In the language of the opinion, the justices of the court “did" not feel compelled to shut their eyes” to certain well-known facts in reference to the use of grain elevators in transferring grain from railway cars to vessels,—that this method involved (lie use of a railway track, entering a fixed or stationary building, an elevator apparatus, an elevator hopper scale for weighing the grain, and a discharge spout for discharging the grain into the vessel. Applying to the patent these; facts, and other facts referred to in the opinion, which were not averred in the bill but were generally known, the court held that the combination claimed was a pure; aggregation, and affirmed the decree of the court below, dismissing the bill.

The patents sued upon in this case are for improvements in button-fastening staples, to be used in attaching buttons to shoes. The Vinton patent describes a staple made of wire. The claims are as follows:

(1) “As an article of manufacture, a button-fastening staple composed of wire, tbe legs of wliicb are provided with V-shaped points broader than the diameter of the wire from which the staple is made, the cutting edges of both of said points being substantially at right angles to the length of the staple head, substantially as described.”
(2) “A staple fastener for leather work, it having V-shaped points spread wider than the diameter of the wire, and set at one side of the center of the wire forming the legs above the point, to thus compel the staple to clinch uniformly in the desired direction, substantially as described.”

The Prentice patent described a wire staple of similar general construction. The claim is as follows:

“A one-piece metallic button fastener, substantially uniform in size throughout, consisting, essentially, in an are-shaped crown or top and two curvilinear side portions diverging from said crown or top, the whole forming a body portion, the curvilinear contour of iho inner wall of which follows substantially the curv linear contour of the outer wall thereof, or is parallel therewith, and an attaching portion consisting of two prongs or legs substantially parallel with each other and depending from the extremities of the body portion, the junction of the legs with the body portion forming comers or bearing shoulders to define said’ body portion, and to limit the penetration of the legs of the fas ener into the material to which it is to be attached, substantially as described.”

Tbe bill makes profert of tbe letters patent in this language:

“All of which will more fully appear by the said letters patent, or by a copy of the same duly certified from the records of the patent office, and in this court to be produced as your honors may direct.”

This is a formal profert, and is sufficient to make tbe letters part of tbe bill, so that they may be considered on demurrer. Dickerson v. Greene, 53 Fed. 247; Bogart v. Hinds, 25 Fed. 484. Courts, in determining tbe validity of a patent, will take judicial. notice of matters of common knowledge relating to the state of tbe art. This proposition is supported by the decision,of tbe court in Richards v. Elevator Co., cited above, where tbe court referred to facts not set forth in tbe record, but recognized because they were perfectly well known.

Tbe rule suggested by Judge Blodgett in Manufacturing Co. v. Adkins, 36 Fed. 554, imposes a proper limitation, to wit, that tbe court must keep strictly within the field of common knowledge, and tbe judge must be careful to distinguish between his own special knowledge and what he considers to be the knowledge of others in the field or sphere where the device is used. “But when the judge before whom rights are claimed by virtue of a patent can say from his own observation and experience that the patented device is in principle and mode of' operation only an old and well-known device in common use, he may act upon such knowledge. The case must, however, be so plain as to leave no room for doubt; otherwise, injustice may be done, and the right granted by tbe patent defeated, without a hearing upon the proof.”

In Root v. Sontag, 47 Fed. 309, the patent was held invalid on demurrer, and the court said that, upon investigation of the question whether the patent was void upon its face by reason of want of novelty or patentable invention, the court xuig'ht “take judicial notice of a thing within the common knowledge and use of the people throughout the country.”

In Brown v. Piper, 91 U. S. 37, the supreme court took judicial notice of the ice-cream freezer in common use throughout the country, and, as illustrating the common knowledge on the subject of the art involved, referred to lire's Dictionary of Arts, Watt’s Dictionary of Chemistry, and the American Encyclopaedia. That court, also, in Terhune v. Phillips, 99 U. S. 593, took judicial notice of the common use and knowledge of corner sockets for show cases; in Slawson v. Railroad Co., 107 U. S. 654, 2 Sup. Ct. 663, of reflectors for directing the rays of a lamp to any desired spot; in King v. Gallun, 109 U. S. 102, 3 Sup. Ct. 85, of the customary trade packages of plug tobacco; and in Phillips v. City of Detroit, 111 U. S. 606, 4 Sup. Ct. 580, of the method of constructing pavements by preparing a foundation, placing the blocks thereon, and filling the space between with sand.

In New York Belting & Packing Co. v. New Jersey Car Spring & Rubber Co., 30 Fed. 785, Judge Wallace held a patent for a design for rubber mats invalid upon demurrer to the bill, iaking judicial notice of the fact that the design was old as applied to other fabrics, and holding that its application to rubber mats did not involve invention. On appeal the supreme court (137 U. S. 445, 11 Sup. Ct. 193), Justice Bradley pronouncing the opinion, sustained the decree so far as the first claim was concerned, “for the reason stated in the opinion,” which he quoted, including the portion where the judge below took judicial notice of the fact that the design was old as applied to other fabrics; but Justice Bradley thought that, as to the other-more limited claims, proof should have been heard.

In Buckingham v. Iron Co., 51 Fed. 236, Judge Blodgett held a patent void on demurrer to the bill because the court, from common knowledge, took notice that the structure was old.

In Wall v. Leck, 61 Fed. 291, a demurrer to the bill was sustained, the court concluding, from an inspection of the specification, that tire patent did not cover- any patentable process. This decision was affirmed by the court of appeals (13 C. C. A. 630, 66 Fed. 552) in February, 1895, and it appears that the court resorted to a certified copy of the patent, outside the bill, to ascertain Its contents.

in Industries Co. v. Grace, 52 Fed. 124, Judge Putnam recognized that by making profert of the letter's patent the specifications were made a part of the bill, and said that a bill in equity did not necessarily make all the statements of fact contained in a contract or letters patent or other instrument proper parts of its pleadings, either by referring to them, or by annexing them as an exhibit, or by making profert, or by reciting the tenor at length. Claims of the patent become a fundamental portion of the allegations of the bill so far as they are relied upon by the complainant. The judge added:

“So everything in the specifications which must be resorted to by the court in construing the claims might be considered as part of the complainant's pleadings. But all portions which merely set out the state of the art, like recitals of facts in contracts or other instruments, are more or less conclusive on the party who sets them up, yet in the eyes of the law explainable, and not absolutely presumed to have been so alleged as to become the subject of demurrer. * * * It is true that, so far as the specification contains any representations which, if erroneous, may be presumed to have misled the paieut office to the detriment of the public, the patentee may be estopped.”

On the other hand, Judge Putnam said that a patent should not be forfeited because of inapt and somewhat inaccurate descriptions of the state of the art, or where, as in the case before him, the state of the art had been set out somewhat confusedly and with qualifications. All this must be taken in connection with prior cases, which were not criticised nor referred to by Judge Putnam, and from which evidently he did not intend to dissent, and in which the specifications were referred to for facts which had direct bearing upon the scope of the patent and the construction of its claims. The patent is, as is well said by counsel for defendant in their brief, the title deed through which the complainant must derive all his rights. It is the grant of a monopoly, and, with rare exceptions, every statement of the prior state of the art therein contained bears upon the construction, and is a limitation of the grant. The description in the specification of the existing art, and of the applicant’s improvements, form the representations upon which he obtains the grant. Having done so, he is estopped to say that his representations were incorrect. If the recitals of the state of the art do not tend to limit, explain, ór nullify the grant, they are of no possible pertinence, even if the same facts were fully proved aliunde. If, on the other hand, they do have such tendency, the patentee is bound thereby, and the patent must be construed in the light of the facts so recited.

In the light of the decisions above cited, let us look to the patents in this case. The staple shown and described in the Yinton patent is made of wire, and is of a U-shaped form. It is expressly stated in the specification that the general outline or form is the same as in the early Ely patent, to which express reference is made, and which is therefore a part of the Vinton specification. Inspection of the Ely patent establishes tbp absolute identity of the Ely and Yinton staples, so far as general form and shape are concerned. Vinton’s improvement consisted in making a V-shaped point, the apex of which is located at one side of the center line of the leg of the staple, and which is pressed, swaged, or flattened, and thus made broader than the diameter of the wire from which the staple is produced. That is the only possible novelty in the Yinton patent. The setting of the points at one side of the center line of the leg of the staple, and the making of the staple with slightly incurved legs, so that it will clinch in the desired direction, are fully shown in the Ely patent, and admitted to be old by the Yinton specification. Making the cutting edge of the staple points at right angles to the length of the staple head was a matter involving nothing more than ordinary mechanical skill.

Now, it is a matter of common knowledge that if a round wire is pointed, by being pressed or swaged or flattened upon two sides, the <liamotor of the point will be and must be greater than the diameter of the wire. The making of such broadened points upon nails and staple's was a matter of common knowledge years before the date of Vint on’s patent. The old cut nail was made in thin form for the very purpose mentioned in the patent,—that the broad, flattened point might cut a slit in the wood through which the shank would enter, and thereby prevent splitting the wood. Bo it was with common nails and staples. With reference to the patentability of such an improvement the case of Double-Pointed Tack Co. v. Two Rivers Manuf'g Co., 109 U. S. 117, 3 Sup. Ct. 105, is cited, and is pertinent.

The Prentice patent is for a button fastener differing from the Vinton and Ely fasteners only in trilling particulars. Prentice took almost the exact form of the Vinton staple with the beveled ends, and made a slightly different angle between the body of the legs, so as to make; the crown portion with a double reverse curve instead of a single curve. Prentice provided his staple with a sort of supplementary crown, leaving shoulders against which the legs might be clinched. The old paper staph', in common use long before Prentice’s pahmt, had a.Hat top against which the legs clinched, the top and-the logs lying parallel after the clinching operation was finished. If such a staple was required to hold the eye of a button, or any similar object, a portion of the crown must be raised so as not to bind against the paper or cloth or leather; and, the necessity being apparent, mechanical ingenuity was all that was involved in the requisite change of form.

The complainant’s patents are invalid upon tlieir face for want of invention. The demurrer will be sustained, and the bill dismissed, at the complainant’s costs.
