246 F. 834 | 2d Cir. | 1917
(after stating the facts as above). The procedural question raised herein is not without importance, if plaintiff’s contentions are justified. They suggest consideration of (1) the fundamental nature of that portion of a decree not specifically covered by equity rule 71 (198 Eed. xxxviii, 115 C. C. A. xxxviii), i. e., the mandatory part; and (2) the effect of an appeal upon the trial record.
It is not uncommon for the court to distinguish between invalidity and noninfringement in dismissing a patent bill. The cases referred to and recently before us (Thacher v. Transit, etc., Co., 234 Fed. 640, 48 C. C. A. 406, and Oriental, etc., Co. v. De Jonge, 234 Fed. 895, 148 C. C. A. 493) do so, and we do not intimate, either that no lawful right exists to enter such decrees in discretion, or that circumstances may not render that or any other special form appropriate or fair. We do hold that it was not error to sign the form of decree herein.
liven when the whole record is before the appellate court, the assignments of error often (in effect) limit the appeal, in the sense of narrowing the field of discussion. This is pointed out in the case last cited, and this truth was assumed when we said in the Thacher Case, supra, that it was “necessary” to consider only the question of infringement, where the court below had decreed validity, and appellant assigned for error the infringement finding. But we did not, and do not, hold that, had we disagreed with the trial judge in his decree of non-infringement of a valid patent, we should have been in any way precluded from examining the record to ascertain whether the decree was right on the plain principle that there can be no such thing as infringement of an invalid patent.
Considering appellant’s contention in its entirety, it is substantially this: That because some of the evidence solely related to matters of defense, mentally and (so to speak) physically separable from other matters directed to the same legal question, it was therefore both proper and obligatory to enter a decree and authorize a transcript putting the noninfringing defendant to an appeal, in respect of every ruling on evidential values unfavorable to defendant. This is (as above intimated) mere fact finding-, and overlooks the legal certainty that there is no such thing as a dependent or ancillary appeal. Defendant, with bill dismissed, certainly could not have appealed alone or independently from an expression in decree of the fact that the Harris use was not lawfully established; therefore such finding was not part of the mandatory portion of any decree. But because the evidence relating to that use was within the pleadings, and might justify dismissal, and require affirmance of decree, if all else failed, plaintiff was rightly obliged to insert it in the appeal record.
In view of the exhaustive history of art given by the court below, and common knowledge of the heating capacity of the oxyhydrogen or other like flame under blowpipe influence, and the nature of oxidation as (in common speech) a burning process, it seems sufficient to assume and assert, as prior and even familiar art, that any and all metals or metallic bodies capable of oxidation could be and often had been melted (i. e., liquified by heat) or fused (i. e., strictly, melted into combination with others), or converted into oxides and as oxides removed from place, by one or both of the well-known implements, tools, or devices just named.
In such an art, Jottrand proposes, as a new method, the direction of a heating jet upon an object (i. e., oxidizable metal) along any preferred line, thereby raising the metal in its path to a temperature permitting “oxidation without fusion” (fusing here evidently means melting) and “simultaneously” putting an oxygen jet under pressure, on and along the heated line, and then driving the two jets (spaced apart a little) along the line of heat. He says the result of this operation is a cut.
The specification explains that oxides are more “fusible” than the metal itself, wherefore, if his pressure oxygen jet oxidizes at the proper temperature (not staled in the disclosure), the resulting oxides “flow readily,” and his path of preheating becomes a line of “severance, perfectly clean,” and therefore (we infer) he feels justified in calling it a cut.
There is no magic in a name, nor in a claim; that the words preferred by a patentee to define his invention apply literally to another’s device suggests, but does not prove, infringement; there must be a substantial identity, to justify that conclusion of law. Edison v. American Co., 151 Fed. 787, 81 C. C. A. 391.
Assuming, then (for argument’s sake), that defendants have cleanly severed metals with flame and jet, plaintiff cannot monopolize method, action or means by tire word “cut,” and since the means are not sought to be covered by this process patent, some other novelty and merit must be discovered to justify the grant. If found at all, the patentable invention must rest in the novel application of some thermo-chemical action so functioning, when instigated by Jottrand’s disclosure of old means, as to produce successively metallic oxides, and removal of same, within so confined an area as to justify calling the cleared space a cut, rather than a hole or hack.
Accordingly it is urged that, observing (dehors the specification) that the blow flame will easily heat to (say) 1000° C., at which temperature .oxygen combines with iron, that iron melts at about 1520° C., and its oxide at 1250° C., there is within this indicated range room to create and remove a line of oxide without disturbing the adjacent masses of iron not directly in the path of the heating flame, which may fairly be inferred from the disclosure as preferably of small area, or width. Such use of blow flame and oxygen jet is said to differ from everything in the prior art, in that it suggests, and indeed requires, a “pro
While noting that Jottrand does plainly contemplate (in his specification) punching holes as well as sawing with his flame and jet, wc think that the foregoing states the best case that can be made in support of any such invention as is claimed; for we pass as equally obvious and irrelevant any possibility of invention in the machine or appliance used in the specification to illustrate the method. A patent was obtained on that, which is not here in suit, and no limitations, expansions, or explanations of the method can be based on the mechanics of Jottrand’s apparatus; for it is also obvious that this is not one of those twice-patented inventions, as to which it is impossible to imagine an infringement of method that would not also infringe the only possible machine or device working by or in that method. If this patent is good, it is a true process.
Whether there is virtue in it depends’on this question of fact: What is the thermo-chemical action taking place in the hole, cut, kerf, opening, or solution of continuity produced by a preheating flame applied to oxidizable metal and followed by an oxygen jet under pressure, be said jets or flames narrow or broad? We think it plainly proved that the metal burns, and is blown out of the preheated area partly as oxide and partly as melted metal.
We do not think this method of removing metal either from a hole, or a cut can be thought new after Dr. Menne’s publications of 1903-04. The Menne patents we also regard as publications, as his claims were not directed to Jottrand’s goal. In the patent of 1902 (703,940) Menne discloses briefly the thermo-chemical action so laboriously sworn to in this record; and in his address he describes the release of one piece of metal from another by “melting through” one of them' — ■ the same being a stated equivalent for “sawing through,” and that Jott-rand’s cut is a cut by melting was admitted by all the experts — who really could not disagree, except as to how much of what was removed was oxidized and how much was unoxidized metal, a debate we cannot regard as important.
Plaintiff appeals to the rule, fully recognized by us, that prior publications, to be effective, must substantially furnish such details as are necessary for the practical working of the alleged invention. Seymour v. Osborne, 11 Wall. 516, 20 L. Ed. 33; McMillin v. Barclay, 5 Fish. 202, Fed. Cas. No. 8,902; Hill v. Evans, 31 L. J. 463. We find that for everything done by this defendant (very rough work) Menne was and is a much better- and clearer guide than Jottrand; whether the latter has anywhere disclosed a means for finer work is not before us. TIis cutting and Menne’s melting are as methods or processes identical; they are so for reasons that go back to chemical fundamentals, and that his cutting device may be clever, and has small, neat apertures, justly spaced and proportioned, is not now relevant.
It may be added that, if Menne’s publications needed strengthening, we should find reinforcement in the Revue Industrielle of April, 1904. The foregoing relieves us of the necessity of considering the other matters of defense, concerning which we give no opinion.
Decree affirmed, with costs.
