263 F. 988 | N.D. Ohio | 1920
Plaintiff’s bill is based upon reissue patent No. 14,255, reissued February 6, 1917, being a reissue of original United States letters patent No. 836,843, issued to T. Van Kannel November 27, 1906. The invention claimed therein relates to an automatically collapsible revolving door, such as is commonly used at the street entrance to public buildings. The defendant has pifrchased, installed, and is using a collapsible revolving door manufactured and sold by the Atchison Revolving Door Company, which has assumed and undertaken the burden and expense of defending this suit. The defenses are (a) that the claims in issue of this reissue patent are void for lack of novelty and lack of invention; (b) that it is void because no inadvertence, accident, or mistake is shown whereby the original patent is inoperative or invalid; and, even if so, the reissue was not applied for with due diligence; and (c) that, if valid at all, these claims must, in view of the prior art, as declared by numerous decisions, be so limited that defendant’s door does not infringe.
The inventor, Van Kannel, was in 1888 granted a patent, being No. 387,571, for a revolving door, having a series of radiating wings, rotating in a casing. It did not have any automatic or collapsible features, although the desirability of providing for tire egress of an excited or panic-stricken crowd was foreseen and disclosed therein. On August 14, 1900, he was granted patent No. 656,062 for an automatically collapsible revolving door, designed to provide for rapid exit by automatic collapse in the event of panic or other necessity therefor. Later, on November 27, 1906, he was granted an additional patent for an automatically collapsible revolving door, being No. 836,-843, of which the one now involved is a reissue. The 1900 and the 1906 patents have been extensively litigated, and defendant contends that all questions touching the validity of the claims now in dispute of the reissued patent have been fully considered and adjudged adversely to plaintiff’s present contentions. These decisions are as follows: Van Kannel v. Revolving Door & Fixture Co. (2 C. C. A.) 219 Fed. 741, 135 C. C. A. 439; Louisville Trust Co. v. Van Kannel (6 C. C. A.) 231 Fed. 166, 145 C. C. A. 354; Van Kannel Revolving Door Co. v. Nathan Straus (2 C. C. A.) 235 Fed. 135, 148 C. C. A. 629; Van Kannel Revolving Door Co. v. Lyon & Healy (7 C. C. A.) 247 Fed. 329, 159 C. C. A. 423; Van Kannel Revolving Door Co. v. Uhrich, decision and opinion by Pollock, District Judge, 247 Fed. 344.
The nature and elements of plaintiff’s invention and of the state of the art respecting revolving doors are so fully stated and described in these several decisions that it is unnecessary to go over the same ground. The conclusions reached in these cases are in accord; indeed, there is an unusual uniformity, not only in the result, but in the reasoning by which the results have been reached. Briefly, my understanding of these decisions is that the Van Kannel 1900 patent, No: 656,062, was held to be the pioneer patent for an automatically collapsible or panic-proof revolving door, and that the inventor was entitled to a wide range of mechanical equivalents, and his patent claims to a reasonably broad construction. More specifically, as regards devices for hinging the radial wings to the spindle or center posts, and devices for connecting or tying the radial wings in an automatically detachable manner, it was held that any device which would produce substantially the same result was an infringement. Accordingly the 1900 patent was in all these cases uniformly sustained, and its claims protected against infringement, as against any construction having any form of hinge or tying device which permitted these results to be realized. On the other hand, and in view of this broad construe
Thus, in Van Kannel Revolving Door v. Revolving Door & Fixture Co., 219 Fed. 741, 135 C. C. A. 439, Mayer, District Judge, had sustained the validity of claims 1, 2, 3, and 8 of the earlier patent, and of claims 13 and 14 of the later patent, and had held that claims 1 and 2 of the later patent were invalid. This holding as to claims 1 and 2 of the later patent is based upon the disclosures of the earlier patent, but as to claims 13 and 14 he held that they stated a combination of elements from which “we have apparently, a new structure in commerce, a new result for operative panic-proof doors, and all described with words of limitation sufficiently definite and limited to save the combination from all the prior art.” The Circuit Court of Appeals, Second Circuit, sustained this decision, except so far as it found claims 13 and 14 to be valid, and reversed as to these, holding that they also were anticipated by the disclosures of the earlier patent. Judge Mayer had stressed particularly this feature of the flexible tie, and the great merit thereof in permitting all the doors to collapse upon the release of any one fastening, and the easy restoration of all the wings to their normal position; but Circuit Judge Dacombe, who delivered the opinion, said as to these claims that they were merely an attempt to extend the monopoly of the earlier patent by changing the names of the various elements or the location of the folding device, or by, merely combining old elements which would be evident to an ordinary mechanic. The construction held to infringe was not defendant’s present construction, but the tying devices for holding together the wings, it was held, did not avoid infringement, even though they were made of such fragile construction as to be breakable rather than automatically releasable.
In Louisville Trust Co. v. Van Kannel Revolving Door Co., 231 Fed. 166, 145 C. C. A. 354, the decision of the lower court, which held claims 1, 2, and 13 of the 1906 patent valid and infringed, was reversed by the Sixth Circuit Court of Appeals. As to claims 13, this reversal was on the ground that the device for connecting the radial wings together was a bar, instead of a cord or strap or other flexible device, and it was not, therefore, the flexible tie which was supposed to give novelty and patentability to this claim. I do not understand judge Knappen’s opinion as expressing any dissent from the decision of the Second Circuit Court of Appeals, nor any intimation that the claim would be upheld, if it were so narrowed as to be limited to a flexible tying device, but merely that, inasmuch as infringement was not shown, no expression of opinion in that respect was called for. The reasoning of the opinion seems to me to lead to the conclusion that claim 13 was anticipated by the 1900 patent, as claims 1 and 2 were held to be anticipated.
However, in Van Kannel Revolving Door Co. v. Lyon & Healy, 247 Fed. 329, 159 C. C. A. 423, and in Van Kannel Revolving Door Co. v. Uhrich (D. C.) 247 Fed. 344, the construction held to infringe the 1900 patent was precisely the same as that involved in this case. It had the same form of hinge, called by defendant a “trammel hinge,” and the same flexible automatically releasing tie for holding the adjacent faces of the wings together. In the first case the District Court had held claims 1, 2, and 8 of patent 656,062 and claim 3 of patent 836,843 invalid. The appeal as to claim 3 of the latter patent seems either to have been dismissed, or the assignment of error with respect thereto not insisted upon, so that no discussion of it is found in the opinion of the Seventh Circuit Court of Appeals, but claims 1, 2, and 8 of the earlier patent were sustained and given the same broad construction as had been previously given thereto by the earlier decisions already reviewed. Defendant’s plate, called a “trammel hinge,” was held to be a mechanical equivalent of the hinge or wings whereby in the 1900 patent the radial wings were folded together, and the tie or device for connecting the adjacent wings and permitting all to fold upon the release of any one was held to be a mechanical equivalent of the self-releasing locking device called for by the 1900 patent. Judge Pollock’s holding in the other case is precisely the same as to the 1900 patent, and as to claim 3 his holding is that it also was invalid in view of the disclosures of the earlier patent.
Thus it appears that the earlier or 1900 patent has been uniformly upheld, and that no claim ever put in issue of the later or 1906 patent has been upheld, but, on the contrary, has been uniformly held to be invalid. The plaintiff has thus obtained from numerous courts a construction of the 1900 patent that is infringed by any form of double-acting hinges applied to all or any part of the wings, and by any form of self-releasing devices, wherever located and of whatever construction. In other words, the 1900 patent has been held to be a pioneer patent entitled to a broad construction, and to a wide range of mechanical
The claims now in issue of the reissue patent must be held invalid, unless there is a new patentable element embodied therein, not anticipated in the litigated claims of the 1900 or the 1906 patents. The differences between the claims of the reissue patent and of these earlier .patents can be clearly shown only by examining them side by side. It would expand this opinion unduly to quote these claims in parallel columns and point out in detail the points of resemblances and differences. This, however, I have done with care, and as a result am convinced that the changes are in phraseology only, and not in substance. The claims have been merely rewritten and rephrased as respects claims 1, 2, 13, and 23 therein, with a more specific description of the connecting device, so as to limit it to a flexible tie,' and to this extent only may these claims be said to be narrowed. As to claims 3, 23, and 24 a hanger plate is substituted for a hanger disc of the earlier claims, and this defendant contends, not without reason, is broadening intentionally these claims, so as to cover its trammel hinge, already held to be an infringement of the 1900 patent; but, as already said, an examination side by side forces the conclusion that these claims have been merely rewritten and rephrased, with the viéw and in the hope of escaping the adverse decisions of numerous federal courts. No new or patentable combination is disclosed thereby, which would not be an infringement of the earlier or 1900 patent.
This conclusion renders unnecessary an examination of the second defense relied on, namely, that no inadvertence, accident, or mistake is shown in the original patent as a basis for the reissue, and that, even if it were, due diligence was not exercised in applying for the
This motion will be denied. Plaintiff’s bill will be dismissed, at its costs.
