(after stating the facts as above). The street pavement of the Warren patent is plainly differentiated from the pavement structures in practical use before his invention, and no serious effort has been made to show its anticipation by any of the known and practical methods of making roadways. The old and well-known forms of such structures included roadways made of granite or other hard stone blocks, vitrified brick, blocks or strips of wood, and well-known macadam. A more modern, and yet well-known, pavement is known as “sheet asphalt.” Each of these forms had its well-known advantages and disadvantages. The structures of blocks of granite or other stone, or brick, were notably durable, but they were noisy and slippery. Blocks of wood become too smooth and slippery. A defect common to all block pavements, whether of wood, or stone, or brick, is that their joints become harbors for filth, causing such pavements to become very unsanitary. The macadam was made entirely of stone broken into pieces of irregular sizes and laid in layers, the bottom one being generally of large cracked stone filled in with finer stone. Over this was laid a layer some inches deep of broken stone rolled down with heavy rollers, and on top a surfacing of fine stone dust, which, when wet, formed a temporary cement. This is not particularly noisy, but in wet weather is muddy or pasty, and in dry weather very dusty. In durability it was very defective. The macadam roadway is the foundation ordinarily for the Warren bitulithic structure, as shown by the specifications of the patent.
The sheet asphalt pavement belongs to a later class, and, like the Warren pavement, is intended only as a top or wearing section over a foundation of broken rock like the ordinary macadam. The surfacing of the pavement is composed of sand with the interstices filled with bituminous cement. If made with a bitumen hard enough to constitute a rigid structure at summer temperatures, it is shown to be so brittle in severe cold as to crack and break up ttnder traffic. If soft enough to resist the breaking effect of traffic during cold weather, the evidence tends to show that the grains of sand through friction slip by each other, and under the influence of traffic the sheet surfacing is subject to be pressed into irregularities, making an uneven or humpy surface, resulting in disintegration. Neither is such a pavement so waterproof as to prevent altogether the penetration of water with bad results. Aside from the defects in the matter of durability under ordinary street traffic conditions, it is shown that the standard asphalt pavement is unduly slippery and affords a bad footing for horses, especially when wet or upon slopes.
Warren’s invention, shortly stated, consists in the' discovery that an aggregate of large and small pieces of stone, together with a certain proportion of stone dust, all mixed together and thoroughly permeated with bitumen or asphalt, results, when set, in a compact, stable structure, and is less liable to disintegrate from traffic or weather than any other method of grading or arranging the mineral constituents. Under the evidence, the particles are more compact in their relation to each other, and there is a minimum of friction in their interaction. The larger pieces of stone withstand the tendency of the small grains or dust to slip by each other and change the form
haying on one side for later notice certain patents which have, in a way, been referred to as anticipations, and the use of an asphalt concrete as a lining for a reservoir on the Pacific Coast, the great weight of the evidence and argument has been addressed to an alleged anticipation in .1896 and use since that date of a bit of sidewalk in front of the Asphalt Street Paving Company’s office at Tong Island City, N. Y. If the defendant’s evidence is to be believed and credited as precisely describing the mixture of the materials employed in building this piece of sidewalk, it must be conceded that the method and materials used in that pavement are such as are covered by the fifth, sixth, and eleventh claims of the Warren patent, they being the broad claims allowed Ihe inventor. Í1: may also be conceded that the infringement here involved substantially follows the method and materials claimed to have been used in the sidewalk construction referred to. The Asphalt Street Paving Company, which constructed the street pavement at Owosso, and which has assumed the defense of this case, very emphatically urge that, if the Owosso construction infringes the broad claims of the Warren patent, their 1.896 sidewalk was an anticipation. But this conclusion does not necessarily follow, for the argument loses sight of the question as to whether the sidewalk construction relied upon as an anticipation was anything more than an abandoned experiment. Whether á patentable invention would be involved by the employment of the same construction for roadway purposes which had been publicly employed for sidewalk purposes is another question, and one which we pretermit now as not necessarily presented upon the facts of this case.
The lining in the reservoir, says Stanton’s paper, “was painted with hot asphaltum paste mixed in the same proportions, but boiled a much longer time, until when entirely cold it was hard and brittle, breaking under a hammer like glass, yet tough, elastic, and pliable with the least warmth.” It is evident that such a lining was not designed or fitted to meet the wear and disintegrating influences to which the wearing section of a street pavement would be subject, and that it taught little or nothing in the art of street paving. The conditions involved in a successful street pavement are so materially different from those involved in waterproofing a reservoir as not by any means to make the solution of one the solution of the other. The disclosures with respect to the usefulness of such a composition for a reservoir teach little of value as to the other. Clough v. Barker, 106 U. S. 166, 176, 1 Sup. Ct. 188, 27 L. Ed. 134; Ajax Metal Co. v. Brady Brass Co. (C. C.) 155 Fed. 409, 419. The use of an asphalt cement foundation for machinery was purely experimental. It is quite remote from street-paving construction, and may be dismissed, both as an abandoned experiment and as teaching nothing of value in the art of street paving. The shed driving floor
The sidewalk construction was much the closest approximation to the invention of Warren. That Warren believed himself to be the discoverer of his composition for street paving is presumed from his oath to that effect, and that presumption must stand until overthrown by very clear evidence. Smith v. Goodyear Dental Vulcanite Co., 93 U. S. 486, 23 L. Ed. 952; Elizabeth v. Pavement Co., 97 U. S. 120, 24 L. Ed. 1000. He died before the evidence was taken, and was not able to testify in support of this presumption. The circumstance that he was in the service of the Asphalt Company when this pavement was pur down amounts to nothing, in view of the fact that he was then and for a long time afterwards on service in the far West and had no connection whatever with IJpham’s experiments. That he subsequently saw the pavement is by no means enough to charge him with knowledge of the composition. The evidence fails to convince us that he acquired his knowledge from that source. The presumption that he believed himself to be the inventor of the pavement for which he was given a patent must be our starting point in determining whether his patent is defeated by anticipation. That somebody had, in fact, made the same composition before he did does not necessarily defeat his patent. In one sense, he would not be the first inventor in such case. Rut, in the sense of the patent statute, he is the first inventor who, by his own thought, makes an article or material and first perfects and adapts his discovery to actual use, although some one may have previously made a similar article without putting it to practical use or giving; his discovery to the public in any way. Gayler et al. v. Wilder, 10 How. 477, 496, 13 E. Ed. 504; Seymour v. Osborne, 11 Wall. 517, 552, 20 L. Ed. 33; Albright v. Celluloid Co., 2 B. & A. 629, 1 Fed. Cas. 320 (No. 147); Bullock Printing Press Co. v. Jones et al., 3 B. & A. 195, 4 Fed. Cas. 659 ; Agawan Co. v. Jordan, 7 Wall. 583, 602, 19 L. Ed. 177; Whiteley v. Swayne, 7 Wall. 685, 687, 19 L. Ed. 199; Decring v. Winona Harvester Works, 155 U. S. 286, 301, 15 Sup. Ct. 118, 39 L. Ed. 153; The Corn Planter Patent, 23 Wall. 181, 211, 23 L. Ed. 161; Smith v. Goodyear Dental Vulcanite Co., 93 U. S. 480, 498, 23 L. Ed. 952; Gamewell Fire-Alarm Tel. Co. v. Municipal Signal Co., 61 Fed. 948, 951, 10 C. C. A. 184.
The fact that the sidewalk was purely experimental as to the value of such a product for that purpose is indicated by several circumstances. It was one of a number of experiments made about the same time for the purpose of ascertaining uses for asphaltum other than in the form of a sheet-wearing surface for street pavements. The office was upon a street corner. The front sidewalk alone was made of the composition covered by the Warren patent. The larger piece of
“Experience with such pavements as have worn the best shows that they have accidently been made with sand containing but a small proportion of coarser sized particles. Further experimental tests have shown me that it is desirable to have the mineral aggregate rich in particles of the size passing the 200, 100 and 80 mesh sieves, and I have also found that mineral aggregates which carry much fine material will carry more bitumen, will prove more dense and compact, and will have better wearing properties than those made of coarser material and which will carry more bitumen.”
The claims of his patent proceed upon this line. From January 1, .1896, to January, 1900, Mr. Richardson was “superintendent of tests”
The contention that the construction of this sidewalk was not an experiment, because it was laid upon a public highway and subjected to practical public use, does not take it from the category of experiments. It was a product which could only be tested with respect to its durability for pavement purposes by laying it upon a highway. The facts, in this respect, are similar to those in Elizabeth v. Pavement Company, 97 U. S. 126, 24 L. Ed. 1000, where it was held that Nicholson’s pavement had not been in public use, within the meaning of the patent law, because an experimental section had been laid down and used by the public for some six years before he applied for a patent. That use was held, upon the facts of the case, to have been purely an experimental one. The teaching of the Elizabeth Paving Case upon this matter is that a test of utility and endurance made in good faith by putting down a small section of a street paving or sidewalk upon the highway at the expense of the inventor and by consent of those having authority is not such a public use as necessarily to anticipate a subsequent independent invention of the same pavement. Nevertheless, long delay in making his application was urged as indicating that he had abandoned his invention to the public, Put this was met by evidence that he had no other intention than to test its endurance and utility, it being shown that he made frequent close examinations, was constantly inquiring as to how it was liked, and spoke of it as a test he was making to determine its usefulness as a street pavement. Abandonment of an invention in its experimental stage is a question of intention, and may be shown by conduct, even within the two years allowed by the statute. But the use of an invention by the inventor for the purpose of testing its utility, which is not a public use, may continue indefinitely, if for the purpose of perfecting, improving, or testing its utility. That this Upbam sidewalk was not torn up was doubtless due to the character of the experiment. The material was useless for other purposes, and it could not be cast aside or devoted to another use as a discarded experimental machine. The results from the experiment were not deemed important enough to induce the construction of other sidewalks nor the material tried for street-pavement purposes, for it should not be altogether ignored that, though the analogy between street pavement and sidewalk pavement is close, there are material differences between the two problems. In one,
In Potts v. Creager, 155 U. S. 597, 604, 15 Sup. Ct. 194, 39 L. Ed. 275, an alleged prior use was not considered a success “from the fact that the machine was never reconstructed/'’ The effect of conduct as evidence of abandonment is also referred to in Gayler v. Wilder and other cases cited heretofore, as well as in the case of the Corn Planter Patent, 23 Wall. 181, 23 L. Ed. 161, and in Deering v. Winona Harvester Works, 155 U. S. 286, 301, 15 Sup. Ct. 118, 39 L. Ed. 153.
. We are the more indisposed to treat this piece of experimental sidewalk as an anticipation because, in the wide range which has been covered by the evidence in this case, it has not been shown that anywhere had there been constructed a single rod of street pavement according to his plan prior to his invention. Under such circumstances, we cannot think the proof of anticipation strong enough to deprive him of his invention.
The patents relied upon as anticipations need little notice, and have received little attention in briefs or arguments. Those most worthy of attention are the Van Camp and Clark provisional English specification and the British patents to Ward. They are both lamentably lacking in instruction as to the proportions of mineral ingredients of the different grades. They do propose the use of large stones and smaller ones to fill the voids together with asphalt or tar. But they do not' disclose Warren’s basic idea of using the several grades of stones so graded as that the stone aggregate will of itself have inherent stability, which will relieve in large part the burden and strain upon the bitumen binder. Warren gives clear directions as to the construction, and clearly discloses the factor of stability resulting from properly grading the mineral ingredients in excess of that found in the greater density of the sand and asphalt concrete. To overthrow a patent by a foreign one óf prior date, the description of the invention must be in such full, clear, and exact terms as to enable one acquainted with the art to which it belongs to make, construct, and practice the invention. Mere vague and general representations in a foreign patent will not support the defense of anticipation. A fatal objection to the Ward English patents is found in the fact that printed copies were not on sale prior to the actual date of Warren’s invention, which is clearly shown to have been made not later than January 4, 1900. The Warren patents were not published prior to October of 1900.
The fifth, sixth, and eleventh claims are infringed. The ninth is not, as it is not shown that the defendants below employed the “comparatively soft bitumen binder,” made an element of that claim.
The decree must be reversed, and the case remanded for an accounting.
