The action out of which these appeals arose was brought by the Jiffy Lubricator Company, as plaintiff, against The Alemite Company, as defendant, in 1938.
The defendant, in’ its appeal, challenges the validity of the judgment and the fairness of the trial. The plaintiff, in its appeal, charges the court with an abuse of discretion in not increasing the jury’s award and in not adding attorneys’ fees to the judgment.
The vital question for decision is, we think, whether the patent in suit (referred to as the Johnson patent) is clearly invalid for lack of patentable invention over the prior art. If the patent is clearly void, the verdict of the jury is, of course, of no help to the plaintiff and other questions need not be considered.
This controversy purports to be, and, is of record, one between two North Dakota corporations. In reality it is mainly between two large manufacturers of lubricating equipment, the Lincoln Engineering Company, of St. Louis, Missouri, which has financed the prosecution of the action for infringement, and the Stewart-Warner Corporation, of Chicago, which makes and markets the “Alemite Hydraulic Coupler,” and which has contributed to the defense. The action was brought in the Eighth Circuit, no doubt, because plaintiff’s counsel were of the view that the opinion of this Court in Stewart-Warner Corporation v. Jiffy Lubricator Co.,
We do not propose in this opinion to go into a detailed description of the prior art and the history of greasing equipment for motor vehicles. For approximately thirty years the manufacturers of such vehicles have equipped them with tubular nipples or pin fittings at points
The owner of the Gullborg patent took the position that anyone making, using or selling any kind of grease gun to be connected with the Gullborg pin fitting, or making, using or selling a pin fitting to be connected with the Gullborg coupler, was guilty of contributory infringement. The market for grease guns, couplers and pin fittings was large and lucrative. Much patent litigation ensued. The question of contributory infringement reached the Supreme Court in 1935 and was decided on May 18, 1936, in the cases of Bassick Manufacturing Co. v. R. M. Hollingshead Co., and Rogers et al. v. Alemite Corporation,
It is safe to say that in or about 1930, when the Johnsons devised their so called “Jiffy hydraulic coupler” and applied for the patent in suit, virtually all automobiles were equipped with Gullborg pin fittings, and the makers of grease guns with bayonet type couplers, as well as those who made pin fittings which could be used in Gullborg’s combination, were being sued as contributory infringers of Gullborg patent No. 1,307,734. August Johnson and his brother “wanted to get a coupler where we would not have to depend on the pin to hold the coupler on the fitting.” What they wanted “to get away from” was “an Alemite [Gullborg] pin connector.” This was “on account of all our trouble in these inventions of ours, which was on account of the coupler using a fitting that would hook on a pin.” It appears that August Johnson told an automobile mechanic in or about 1928 about making something to do away with the pld type of connector so that he (Johnson) would not have to use the pin on the Alemite fitting, and that he thought he could make something that would work like a drill chuck, utilizing the force from the grease gun to .grip the fitting during the greasing operation. The mechanic understood what Johnson was talking about, and thought it would work.
The production and sale by the plaintiff of the'Jiffy hydraulic coupler was followed by the action of Stewart-Warner Corporation v. Jiffy Lubricator Co., which was considered by this Court on appeal in
While this Court distinguished the Jiffy hydraulic coupler, the accused device in that case, from the device of Butler, and was of the view that the Alemite hydraulic coupler, made by the Stewart-Warner Corporation, did not conform to the Butler .patent, the Court did not hold that whatever advance in the art over the Butler coupler was disclosed by the Jiffy hydraulic coupler would amount to patentable invention.
Following our decision in Stewart-Warner Corporation v. Jiffy Lubricator Co., supra,
He was unable to read into claim 2 of Butler any requirement of springiness or spring fingers which this Court in Stewart-Warner Corporation v. Jiffy Lubricator Co., supra, considered a distinguishing feature of the Butler hydraulic chuck coupler. The Circuit Court of Appeals of the Seventh Circuit affirmed Judge Lindley,. in Lincoln Engineering Co. of Illinois v. Stewart-Warner Corporation,
“In its petition for certiorari, and in argument upon the merits, the petitioner insisted that the respondent’s commercial form of coupler was not that of the Butler patent; that the Circuit Court of Appeals for the Eighth Circuit Court had so held [Stewart-Warner Corp. v. Jiffy Lubricator Co.,
“The petitioner’s principal contention is-that our decision in the Rogers case, Rogers v. Alemite Corporation,
As -the Supreme Court and this Court have. stated, chucks are old and unpatentable as such. They are universally used in lathe and drill assemblies and can be operated manually or by pressure. Perhaps the oldest form of a chuck is to be found in the carpenter’s brace and bit.' What the Johnsons did — as we see it — was to substitute for the bayonet type of connecting means of Gullborg, which was old, a chuck type of connecting means, also old. Had Gullborg used either a manually or a pressure operated chuck to fasten his coupler to a grease nipple, it is doubtful if that would have added anything of novelty to the disclosures of his patent. Substituting an old and well known form of coupler for another form of coupler equally well known, did not, in our opinion, ' require invention, but merely mechanical skill. This Court virtually said as much in the case of Min-A-Max Co., Inc., v. Sundholm,
While that language was not necessary to the decision of the case, it was used advisedly. To use means old in the art to clamp a grease nozzle to a grease fitting so as to form a tight connection, does not involve patentable invention. Compare, Cuno Engineering Corp v. Automatic Devices Corp.,
Implications favorable to the plaintiff which might, perhaps, be drawn from some of the statements of this Count in Stewart-Warner Corporation v. Jiffy Lubricator Co., supra,
Since it is our opinion that the evidence, viewed in the aspect most favorable to the plaintiff, does not sustain the conclusion,that the Johnsons’ contribution to the art of lubrication rose to the level of patentable invention, it is unnecessary to consider other questions.
The judgment appealed from is reversed, and the District Court is directed to enter a judgment dismissing the plaintiff’s claim that the patent in suit is valid and infringed.
Notes
The Stewart-Warner Corporation and the Alemite Corporation, its subsidiary, were also originally named as defendants, but were, by order of the District Court, eliminated from the case with respect to the claim of patent infringement involved in these appeals,
Claim 1, which fairly may be considered as typical of the claims allegedly infringed, reads as follows:
“1. A connector for pressure lubricators comprising a casing having a cylindrical bore terminating at one end in a tapered bore, closure means on the other end having a passage therethrough communicating with the interior of said casing, said passage providing an inlet for lubricant into said cylindrical bore, a hollow piston member slidably received in said casing and adapted to be projected forwardly by the lubricant in said cylindrical bore under pressure developed in said lubricator during its operation and conveyed into said cylindrical bore through said inlet, rigid clamping members on said piston and slidable therewith having portions slidably engaging the tapered portion of said casing for securely clamping a fitting, and sealing means in said hollow piston against which the fitting is adapted to press when held by said clamping bore, a closure for the other end of said casing having a passage communicating with the bore of said casing to convey lubricant thereinto, a hollow piston member in said bore in said casing and movable by the pressure of lubricant in said bore developed in said lubricator during the operation thereof, rigid clamping members having portions arranged between said piston member and the casing, inwardly projecting clamping portions on said members, said members having surfaces slidably engaging the tapered1 wall of the casing whereby said clamp-, ing portions are moved radially inward when the piston merriber is moved toward the tapered end of said casing for clamping the end of a fitting when inserted in the end of said casing, and a sealing means in said hollow member against which the end of the fitting is adapted to press, said means comprising a flexible washer secured in said hollow piston adapted to be pressed against said fitting by the pressure of the lubricant being dispensed.”
