[251 U.S. 134, 135] Messrs. Clarence E. Mehlhope, of Chicago, Ill., and Arthur H. Ewald, of Cincinnati, Ohio, for petitioner.
Mr. V. H. Lockwood, of Indianapolis, Ind., for respondents.
Mr. Justice McKENNA delivered the opinion of the Court.
Suit brought in the District Court of the United States for the District of Indiana to restrain the infringement of a patent for a retaining wall, which, to quote petitioner, is "a wall to prevent the material of an embankment or cut from sliding."
After issue joined and proofs submitted, the District Court (Anderson, J.,) entered a decree dismissing the bill for want of equity. The decree was affirmed by the Circuit Court of Appeals, to review which action this writ of certiorari was granted.
The bill in the case is in the conventional form and alleges invention, the issue of a patent numbered 705,732, and infringement by respondent. The prayer is for treble damages, an injunction, and accounting.
The answer of respondent is a serial denial of the allegations of the bill and avers anticipation of petitioner's device by prior patents and publications, in this and other countries.
This summary of the issues is enough for our purpose and we need only add preliminarily to their discussion that Bone's device has the sanction of a patent and a decision sustaining it by the District Court for the Northern District of Ohio and the Circuit Court of Appeals for the [251 U.S. 134, 136] Sixth Circuit. The difference of decision in that circuit and the Seventh circuit is an important consideration and must be accounted for, which is best done by a display of the patent and the case.
First, as to the patent: It describes the invention as being one that--
The following figure represents a cross-sectional view of the device- A representing the masonry, B the material retained, and B1 the earth on which the wall rests. The metal parts within A are indicated by the smaller letters.
The patent does not insist upon that form of the masonry in all particulars. The base of the wall may be, it is said, 'varied to suit the circumstances'; it (the base) may extend to the rear rather than the front 'with proper proportions of metal ... the form shown in the drawings being what might be called an inverted T, while those suggested would be in the form of an L or reversed L.'
The utility of the wall of these shapes is represented to be that it is 'not so liable to be overturned from the pressure of material behind it as would be a wall of the same height and area of section but having a rectangular, trapezoidal or triangular shaped section,' the latter shapes requiring more masonry. And it is said that the patented wall, 'having more base and less weight' than such other shapes, 'will rest more securely on a soft or yielding foundation, the weight of the material resting on the heel' causing the latter 'to press on the earth below, and thus cause friction to prevent the whole wall from sliding outward.' This is the especial effect of the patent, achieved by the wall of the shape described, and distinguishes it, is the contention, from the retaining walls of the prior art.
The patentee admits, however, that retaining walls had been 'constructed of concrete and steel, but none' to his 'knowledge' 'had been supported on their own base as' his, nor had 'any of them entirely inclosed the steel within the concrete,' nor had 'any of them used the weight of the material retained as a force to retain itself.'
Such, then, is the wall and the utility attributed to it. The combinations which may be made with it are set forth in 17 claims, of which 1, 3, 5, 16, and 17 are involved in the present action. Counsel for petitioner considers, however, that 1 and 17 are so far illustrative that the others need not be given. They are as follows:
So much for the device of the patent. How far was it new or how far was it anticipated?
Bone's idea was conceived in 1898, and his patent issued in 1902, upon an application made in 1899, but according to his counsel the value of the invention was not recognized 'until after the lapse of several years,' when he, Bone, brought a suit against the city of Akron, Ohio, in the District Court for the Northern District of Ohio, in vindication of the patent and in reparation for its infringement. He was given a decree which was affirmed by the Circuit Court of Appeals for the Sixth Circuit. 221 Fed. 944, 137 C. C. A. 514.
The District Court (Judge Day) gave a clear exposition of the patent, the relation of its metal parts1 to the masonry [251 U.S. 134, 139] parts and their co-operating functions, and adjudged the patent valid and the wall of the city of Akron an infringement of it.
The Circuit Court of Appeals affirmed the decree. The court said that the record disclosed nothing which anticipated 'the substantial thought of the patent.' If it had done so, or, to quote the exact language of the court:
Those decisions confronted the District Court in the present suit and fortified the pretensions of the patent. They were attacked, however, as having been pronounced upon a different record and this conclusion was accepted by the District Court. The latter court found from the new evidence the existence of a structure upon the nonexistence of which the Circuit Court of Appeals for the Sixth Circuit based its conclusion. The District Court said that Bone was not the first to do the things he asserted he was the first to do, and that whatever the record in the Sixth Circuit might have shown, so far as the record before the court 'was concerned, the absolute converse of that proposition' had 'been demonstrated.'
The court, therefore, as we have said, dismissed the bill for want of equity.
The decree was affirmed by the Circuit Court of Appeals; indeed, the reasoning of the District Court was approved after painstaking consideration of the patent and an estimate of the anticipatory defenses; none of which the court said was introduced in the Akron Case, 'otherwise a different conclusion would have been reached,' adducing the opinion of the court. 249 Fed. 214, 161 C. C. A. 247. This being so, and there is no doubt it is so, the present case is relieved of the authority or persuasion of the Akron Case and it becomes necessary to consider the prior art and decide the extent and effect of its anticipation.
We have given a cross section of the device of the [251 U.S. 134, 141] patent, showing its shape and strengthening 'metallic members,' and the patent informs of their co-operative function. We reproduce the device and set by its side the Marion county wall for comparison.
If we may assign novelty to the Bone wall and consider it a broad advance upon the prior art [the extent of its advance, if any, we shall consider later], we may assign infringement of it by the Marion county wall. To an examination of the prior art we are therefore brought.
It would be difficult to add anything to the consideration and comment of the Court of Appeals. The court cited in support of its judgment a patent issued to Francois Coignet in 1869, and one issued to Stowell & Cunningham in 1899 upon an application made in 1897, and to articles written by P. Planat which appeared in 1894 and 1896 in a scientific magazine called 'La Construction Moderne,' published in Paris; also a publication which appeared in Germany in 1894 concerning a wall which is given the name of Bauzeitung wall. The article recites that a 'utility model patent' had been granted, consisting 'of a vertical and a horizontal member.'
The Coignet patent is somewhat indefinite. It relates, according to its declaration, to 'monolithic structures, or articles made of artificial stone paste' into which irregular shaped irons are introduced to be 'arranged in such a [251 U.S. 134, 142] manner as to interlace each other, so that by the combination of this metallic skeleton and of agglomerated artificial stone paste the thickness of the walls or size of the articles may be considerably reduced and yet great strength be attained.'
It will be observed that there is nothing explicit of how 'stone paste' and the 'irregular shaped irons' operate or co-operate, aside from their cohesion or interlacing. Their arrangement is not definite as the 'metallic members' in the Bone patent are, so that there might be as in that patent, reinforcing metal in the heel of the wall acting with its upright portion serving the function, to quote Judge Day, 'of a cantilever beam whereby the weight of the material pressing upon the heel is transferred to the upright of the wall and operates to retain the wall in a vertical position.'
If there was any prophecy (to borrow counsel's word) in it the world was slow to discern it, and we are not disposed to give much anticipating effect to it, a view in which we have confirmation in the disclaimer of Bone-he conceding he was not the first to discover the art of reinforcing concrete.
The Planat publications are more explicit. We there see a relation between the metallic and masonry parts of a wall and their cooperation to produce strength in the wall and resistance to the pressure of and bulging from the stress of earth behind it. Both articles the Court of Appeals said, 'deal with retaining walls of reinforced concrete of the cantilever type' and quoted from the article of 1896 as follows:
The court did not enlarge upon other examples of the prior art nor do we think that it is necessary to do so. The court, however, referred to a publication in Bauzeitung and the patent to Stowell & Cunningham. The former is too technical to quote and the latter has not the simplicity of the Bone device; but both publication and patent represent structures that resist a tendency to tilting or bulging from the pressure of the earth in their rears. The Bauzeitung article did this by a wall which consisted of a 'vertical and a horizontal member' which were 'rigidly connected with each other' and--
It is further said:
It will be observed, therefore, that there are no metallic reinforcing members. It is the shape of the wall-one having a base extending to the rear in the form of an L, the exact antecedent of one of the shapes described by Bone as having advantage over other shapes. And there was also the suggestion of the value of a firm connection between the 'vertical and horizontal member.' In other words, the publication showed a retaining [251 U.S. 134, 144] wall having a heel such that the weight of the earth thereon would tend to keep the wall erect, an effect and operation that Bone declares in his patent no wall had attained prior to his invention. And that effect and operation the Circuit Court of Appeals for the Sixth Circuit considered the essence of the Bone patent, and the court said that-
The Stowell & Cunningham structure is, as we have said, somewhat complex in its mechanical parts. But these are but details; the physical laws that they are to avail of are explained so that 'the volume of masonry' of retaining walls may be reduced yet retain their strength by the use of metallic reinforcements.
Counsel attacks the sufficiency of the asserted anticipations, especially the publications, and in effect says that whatever conceptions lurked in them conveyed no suggestion of a 'concrete entity,' to use counsel's words, to execute them and laments that Bone should be robbed of the credit and reward of adding to the world's useful instrumentalities which, but for him, would have remained in theories and the 'dust from which respondent recovered them.'
To execute theories by adequate instrumentalities may indeed be invention, but an answer to petitioner's contention we have given by our comment on the Bauzeitung and Planat publications and the fullness of their expositions. Bone may have been ignorant of them and his device may not have been their suggestion. They seem to have been unknown to American engineers, not even the interest of the controversy in the Sixth Circuit having developed their existence. From this local ignorance nothing can be deduced favorable to the patent. Its device having been described in printed publications, although in foreign countries, patentable novelty or originality cannot be asserted for it. Section 4886, R. S.; 29 Stat. 692, c. 391 (Comp. St. 9430). [251 U.S. 134, 145] Such is the provision of the law and we cannot relax it in indulgence to what may seem the individual's merit.
The Circuit Court of Appeals, to show the progress of the prior art, made use of the illustrations of the patents and publications
that preceded Bone's, and we also avail ourselves of the same to show that Bone's patent was a step, not a leap, in that progress, and that the only originality that can be accorded it is in its special form and there can be no infringement except by a copy of that form or a colorable imitation of it. We do not think the Marion county wall is subject to either accusation and the decree of the Circuit Court of Appeals is
