Lyon & Lyon, Leonard S. Lyon, and Henry S. Richmond, all of Los Angeles, Cal., for plaintiffs.
R. Welton Whann and Robert M. McManigal, both of Los Angeles, Cal., for defendants.
This cause, in equity, was originally brought by the owners of Letters Patent No. 1,277,600, 1,625,391 and 1,625,414,— all devices relating to tools for cutting and removing pipe from wells. Before the trial, the case was consolidated with another one pending before me between the same parties and relating to Letters Patent No. 1,625,391 and 1,625,414 only.
At the trial, Letters Patent No. 1,277,600 and No. 1,625,414 were eliminated by the plaintiffs. So that the only issues tried were the validity and infringement of Letters Patent No. 1,625,391.
On the evidence before me, I am of the view that the patent covered by Letters Patent No. 1,625,391, issued April 19, 1927, to Reilly and Stone, is good and valid in law and owned by the plaintiffs, that the defendants have infringed Claims 1, 2, 3, 4, 5, 6, 7, 8, 9, 12, 14, 15, 16, 17, 18 and 21 of the patent, and that plaintiffs are entitled to a permanent injunction against the defendants and an accounting.
In what follows are set forth my conclusions on the fundamental questions involved.
The inventors describe the object of their invention in this manner:
The devices accused have, by agreement of the parties, been limited to three, represented in the record by (1) the model, which is Plaintiff's Exhibit 10, the drawings for which are Defendants' Exhibit E, (2) Defendants' Exhibit C and (3) Defendants' Exhibit D.
The plaintiffs have charged infringement of all the claims of the Reilly-Stone patent except Claims 10, 11, 13, 19 and 20.
From the claims, the plaintiffs have chosen more specifically as a basis for proving infringement or as typical of the remainder of the claims charged to have been infringed, Claims 1, 12 and 21, which read:
To each of the accused devices, the plaintiffs have sought to apply some of or all these typical claims, thus applying Claims 1, 12, 21 to Device 1 (Exhibit E), Claims 1, and 21 to Device 2 (Exhibit C) and Claims 1 and 21 to Device 3 (Exhibit D).
In their challenge to the validity of the patents and of the claims charged to have been infringed, and especially of the claims chosen as typical, the defendants insist that the elements of the combination in the patent in suit are old in the art and do not rise to invention over the prior art. To this is added the very familiar claim that whatever the deviation from the prior art is merely such as could have occurred to any mechanic skilled in the art.
A consideration of the testimony given in court, a study of the art and its history, a re-examination of the physical exhibits before the court, and of their methods of operation, lead to the conclusion that, while the elements of the combination may be old in the art, there is nothing in the prior art akin to the manner in which they are combined in this patent in order to produce a better result, — that is, a tool which, with great commercial success over a long period of years, achieved results not heretofore attainable by any prior device known to the art. This is invention over the prior art. Webster Loom Co. v. Higgins, 1881, 105 U.S. 580, 592, 26 L.Ed. 1117; Atlantic Refining Co. v. James B. Berry Sons Co., Inc., 3 Cir., 1939, 106 F.2d 644, 650; Forestek Plating & Mfg. Co. v. Knapp-Monarch Co., 6 Cir., 1939, 106 F.2d 554, 557; Amdur on Patents, 1935, p. 97.
The correctness of this conclusion is attested to by the chief expert of the defendants, Glen Bowlus, who, in answer to a series of questions propounded to him at the beginning of his cross examination, stated definitely that the chief elements of the combination, that of the pivoted cutters 11, the feed ring 15, the spring 21, the shear pin 28 and the overshot members 22 of the patent in suit, were not to be found in any of the long list of patents which have been pleaded either as anticipation or offered as prior art and which he had analyzed.1
He applied the same conclusion to the Kammerer patent, Letters Patent No. 1,277,600, issued September 3, 1917, (Transcript, Volume 6, pp. 569-572) of which the patent in suit was an improvement.
It is true that the same expert claimed, and counsel for the defendants have argued, that, while these elements are not found in the same combination in prior patents, each of them can be found in one or another of the patents in the rich prior art in the field of tools for cutting and removing pipe from oil wells. But this fact does not stand in the way of validity.
For, it is a fundamental principle of the law of patents, declared by the Supreme Court in a leading case, dating back to 1878, that the separate presence of the elements of a combination in three or four other patents in the prior art does not preclude a finding of invention when these elements are so combined as to produce a new or better result. The case to which I refer is Bates v. Coe, 1878, 98 U.S. 31, 48, 25 L.Ed. 68, where the court says: "Where the thing patented is an entirety, consisting of a single device or combination of old elements, incapable of division or separate use, the respondent cannot escape the charge of infringement by alleging or proving that a part of the entire thing is found in one prior patent or printed publication or machine, and another part in another prior exhibit, and still another part in a third one, and from the three or any greater number of such exhibits draw the conclusion that the patentee is not the original and first inventor of the patented improvement."
To the same effect are Brinkerhoff v. Aloe, 1892, 146 U.S. 515, 13 S.Ct. 221, 36 L.Ed. 1068; Diamond Rubber Co. v. Consolidated Rubber Tire Co., 1911, 220 U.S. 428, 439, et seq., 31 S.Ct. 444, 55 L.Ed. 527; National Hollow Brake-Beam Co. v. Interchangeable Brake-Beam Co., 8 Cir., 1901, 106 F. 693, 706, 707; Emerson Electric Mfg. Co. v. Van Nort Bros. Electric Co., C.C.E.D.Mo.1902, 116 F. 974; Craft-Stone, Inc., v. Zenitherm Co., Inc., 3 Cir., 1927, 22 F.2d 401, 403; Electrons, Inc., v. Coe, 1938, 69 App.D.C. 181, 99 F.2d 414, 422, 423; Atlantic Refining Co. v. James B. Berry Sons Co., 3 Cir., 1939, 106 F.2d 644, 650.
As it is not my aim to do other than indicate, in a very general way, the conclusions reached, it is unnecessary to go fully into the bases for the defendants' denial of infringement. The background of the defendant, Ira J. McCullough, shows the acquisition of knowledge in the art in the employ of one of the plaintiffs, the Baash-Ross Tool Company. The device manufactured is, in all respects, similar to the device of the plaintiffs.
In fact, the defendants seem to stress chiefly the fact that the device of the plaintiffs offered in evidence is not the device they manufacture. This is immaterial. For the question of infringement does not turn around ...
