2 Biss. 472 | U.S. Circuit Court for the Northern District of Illnois | 1871
The issue in this case under the pleadings is simply upon the question of the identity of the three devices used by the defendants With that invented and patented by Nyce. It appears from the evidence that the specifications in the original letters patent, described a building constructed with two or more outer walls with the space filled with chaff, tan-bark, charcoal or other non-conducting substances, after the manner usually adopted for the construction of ice-houses. This building was to be divided into upper and lower rooms or chambers by a floor to be made of metal, recommending galvanized iron as the best material for the purpose. The upper room or chamber was to be filled with ice, packed upon said metallic floor, and the articles to be preserved were to be placed in the lower room or chamber. The patentee then describes the method in which said floor is to be supported, providing for transverse .ioists, the upper edges of which should be beveled so as to cover as little as possible of the under surface of the floor, and the beveled (Ages should be tipped or covered with metal, thereby securing the contact of the atmosphere of the preserving chamber with the greatest possible amount of the surface of the ice floor. Provision was also made for the drainage of the water from the melting ice by means of pipes at the sides of the building, passing through the walls. To secure the necessary degree of dryness in the air of the preserving chamber, certain chemical absorbents were prescribed to be used. The specifications also described a vestibule or entry, to be so constructed as to enable persons to enter the preserving chamber without the admission of external air.
The claims of the patentee under this original patent were: “1st. The construction of a preserving house, whose lower chamber, to contain provisions, is separated from its upper or ice chamber by an air-tight metallic floor, ‘jU,’ supported on metallic joists, ‘L,’ whose upper surfaces consist of a series of thin edges or points, substantially as set forth.” (2d claim, not important in this case.) “3d. The combination of the vestibule and the preserving chamber, constructed as set forth. 4th. The combination of the preserving chamber with the use of the chemicals used for desiccating the atmosphere, and the hygrometric apparatus.” In the re-issued letters the patentee only claims on: “1st. An insulated house * * *. having an ice reservoir above, and separated from it by an air-tight metallic floor. 2d. The combination of such a house with a vestibule. as described. 3d. The use in such a house of a hygrometer, constructed substantially as explained.”
It will thus be seen that while in his original patent the inventor claims the various parts of his house and apparatus in combination, in his re-issued patent his first and chief claim is for an air-tight metallic floor, separating the preserving chamber from the ice reservoir. He does not as in the first patent, claim for a metallic floor, resting on metallic joists with thin edges, although he states that method of construction as the best, when the lowest degree of temperature is desirable. But he says: “It is obvious that there are purposes to which these improvements are applicable, that do not require cold so excessive or an atmosphere so dry as to preserve fruit through successive seasons. For example, to preserve lager beer a temperature of forty-six degrees will answer, forty-three degrees being the best temperature to insure the slow and even chemical changes necessary during its two weeks of fomentation, a necessity which has heretofore closed almost all the breweries of the World from June to September. For all such purposes the strict conditions may be modified, as greater or less cold or dryness is desired. If moisture is not detrimental, leave out the absorbents. If a uniform temperature of forty degrees will suffice, the walls may be less perfect, and the instructions for insulating the metal ice floor less rigidly adhered to.”
The defendants are brewers, and the alleged infringements are in certain buildings constructed by them in this city, for storing lager beer during the hot weather. The proof shows that all said buildings contain an ice reservoir, separated from the store or beer room by a galvanized iron floor, resting on wooden joists with flat edges or bearings, or on. wooden knobs; that said floors pitch or descend from the center towards the outer wall, and next the wall have a trough or gutter to catch the drippings from the melting ice — the floor not fitting tightly to the wall. Defendants do not use the chemical absorbents described in the patent, but to protect .the contents of the store room from the drippings from the ice floor, caused either by leakages or condensation, they construct another floor of zinc, or zinc and wood, under the metallic ice floor, which is made tight and sloping, or pitching from the center to the walls of the room. In fact, they construct a zinc roof beneath the ice floor and over the contents of the store room, to catch and carry off the water which would otherwise drip from the ice floor upon the beer casks. And defendants claim that the floor thus used by them does not infringe on complainant’s patent, because: First. Complainant’s patent calls for an iron floor, resting on iron supports — iron on iron. Second. The water runs off from their floor differently from what it does from floors described in the patent. Third. Their floor is not air-tight. It has a space next the wall, and also leaks some. Fourth. They use the metallic ice floor in combination with the
By their first point the defendants insist that the patentee is bound by the specifications in his original patent, and can only hold under his patent an iron floor on iron supports or bearings. This involves the question as to the validity of the re-issued patent.
Tile 13th section of the act of July 4, 1830 (5 Stat. 122), provides that: “Whenever any patent * * * shall be inoperative or invalid by reason of a defective or insufficient description or specification, or by reason of the patentee claiming in his specification, as his own invention more than he had or shall have a right to claim as new, if the error has or shall have arisen by inadver-tency, accident or mistake, and without any fraudulent or deceptive intention, it shall be lawful for the commissioner * * * to cause a new patent to be issued to the said inventor * * * in accordance with the patentee’s corrected description and specifications.”
In considering the validity of a re-issued patent, then, the only question is as to whether the invention described in the reissued letters is to be found in the original model, specifications or drawings of the inventor. In other words, is it his invention? If it can so be found, although defectively described, or if claimed with other matters not new or not the invention of the patentee, the re-issue is granted; and the action of the commissioner in granting the re-issue cannot be impeached or inquired into, except for alleged fraud or collusion. Blake v. Stafford [Case No. 1.604].
In the re-issued patent the patentee need not claim all that was claimed in the original patent. He may retain what he deems proper. Crompton v. Belknap Mills [Id. 3,-400]. In this ease the original specifications described a metallic ice floor, but claimed it in combination with the beveled and metal-tipped joists or supports. And the courts must accept the action of the commissioner as the lawful exercise of his authority, unless it is apparent upon the face of the patent that he has exceeded his authority, and there is a clear repugnancy between the old and the new patent. Woodworth v. Stone [Id. 18,021],
“An inventor is always at liberty in a renewed patent to omit a part of his original invention, if he deems it expedient, and to retain that part only of his original invention which he deems it fit to retain. No harm is done to the public by giving up a part of what he has actually invented; for the public may then use it, and there is nothing in the terms or policy of the patent act which prohibits such a restriction.” Carver v. Braintree Manuf’g Co. [Id. 2,485],
“When the commissioner accepts a surrender of an original patent and grants a new patent, his decision in the premises in a suit for infringement is final and conclusive, and is not re-examinable in a suit in the circuit court, unless it is apparent upon the face of the patent that he has exceeded his authority, that there is such a repug-nancy between the old and the new patent that it must be held as a matter of legal construction, that the new patent is not for the same invention as that embraced and secured in the original patent.” Per Clifford, J., in Seymour v. Osborne, 11 Wall. [78 U. S.] 516, citing Battin v. Taggert, 17 How. [58 U. S.] 83; O’Reilly v. Morse, 15 How. [56 U. S.] 111; Sickles v. Evans [Case No. 12,839]; Allen v. Blunt [Id. 216.]
“Corrections may be made in the description, specification or claim when the paten-tee has claimed as new- more than he had a right to claim, or when the description, specification or claim is defective or insufficient, but he cannot under sach an application make material additions to the invention which were not described, suggested, nor substantially indicated, in the original specifications, drawings or patent office molel.” Seymour v. Osborne, 11 Wall. [78 U. S.] 516.
In the re-issue he claims simply the metallic ice floor. This is certainly within the rule. This floor was described in the original specifications, although combined with something else the inventor does not now desire to insist upon. There is no dispute but the patentee was the first inventor of the metallic ice floor, and he had a right to claim it as the sole subject matter of his invention, if he chose to do so. There is no departure from the original subject of his invention. He has merely simplified his claim, and confines it now to a single element, instead of a combination of elements, as at first. He is not confined to iron resting on iron; but may rest his floor on any support which enables it to subserve the object for which it is used.
The metallic ice floor was the main and controlling element of the invention. The method of supporting it. of drying the air, of securing ingress and egress, were mere incidents, whose use secured the more perfect working of the invention. This also disposes of the second objection, that the water runs off differently from defendants’ floor than it does from complainant’s.
It is obvious that some provision must be made for taking off from the floor the water formed by the melting of the ice. but the patentee is not confined to any special method of taking it off. He can carry it off by a gutter or through holes in the wails, or otherwise, as is most convenient. But it is urged, thirdly, that the patentee's floor must be "air-tight,” and it is said defendants’ is not air-tight, because it does not close up and make a tight joint with the wall, but admits a gutter along its edge between the floor and walls. I think it evident the
Suppose a machine is patented in which .a wheel is described as a material part— :a wheel should be a perfect circle — could .an infringer defend by showing that he used a wheel which was not a perfect circle? In other words, can any person use a patented ■device by constructing it in a slovenly or •imperfect manner, so that it will accomplisli the same kind of result as that intended 'by the inventor, but not so perfectly? But, -as a matter of fact, the proof shows that all defendants’ floors were made tight, and some have since become leaky by defective construction. Thus showing that in this regard the defendants attempted to make a tight floor, or an air-tight one.
But the defendants say they use the metallic ice floor in combination with the zinc •floor underneath, and hence they do not infringe. This fact cannot be allowed as a •defense, if in point of fact the complainant’s floor is part of the defendants’ combination, because the Nyce patent is for the metallic ice floor, and any additions or improvements added thereto do not entitle defendants to use what belongs to the owners of this patent. For the purposes to which this device is applied by defendants, I presume the •zinc floor, to take the place of chemical .absorbents, and to prevent drip, is a useful improvement, but that does not entitle defendants to use it without the consent of the patentee.
So, too, with regard to the vestibule. Defendants claim they do not use the vestibule described by the patentee, but tney do use .a room which performs the substantial functions of the vestibule in the patent. That is to say, the store room is entered through ■an adjoining room or entry, thereby preventing the external air from rushing into the preserving chamber or store room; so that this entry, as used by defendants in combination with the store room, is in all essential respects the equivalent of the p't-entee’s vestibule. As this case stands, then, upon the pleadings and proofs, Nyce must be deemed the original and first inventor •of a metallic ice floor for preserving houses, and of the vestibule in combination therewith. This fact, not being denied by the pleadings, must be held to be admitted, or, if not admitted, defendants only ask for proof, and that is furnished by the production of the letters patent. The right to use :and vend this patent has been duly assigned to and is held by complainant. The floors used by defendants are, in their construction and functions, substantially like that described in the patent, and complainant, as assignee of the patent for the county of Cook, is entitled to recover its damages for the infringement.
The matter will, therefore, be referred to H. W. Bishop, Esq., one of the 'masters of this court, to take testimony, and report as to the amount of said damages, and the injunction will be granted according to the prayer of the bill.
