227 F. 436 | 9th Cir. | 1915
(after stating the facts as above).
First. That the processes patented are the result of mechanical skill, and not the product of inventive genius, and the patents are therefore void.
Second. That the processes embodied in the Hassam patents were anticipated by prior patents, by prior use, and by prior publications.
Third. That the appellees, by their acts in inducing the officers of the city of Portland to include their process of paving in an ordinance defining the method, manner, and kind of street pavement to be laid in the city of Portland, with knowledge that all street improvements must, under the city charter, be let to the lowest responsible bidder, waived all rights under their patents, and granted to the appellants the right to utilize the processes covered thereby.
1. There are five elements entering into the construction of a pavement in accordance with the alleged infringed claims of the patents in suit: (1) A bottom layer of uncoated stone. (2) The rolling of the stone. (3) A grouting of cement placed upon the stone and filling all the voids therein. (4) Agitation of the mass to expel the air and fill the voids. (5) A top layer of small uncoated stones compressed into the surface of the grout before it sets.
“The invention of discovery relied upon aa a defense must have been complete, and capable of producing the result sought to be accomplished ; and this must be shown by the defendant. The burden of proof rests upon him, and every reasonable doubt should be resolved against him.”
In the second case the same defense in a suit for infringement was set up-, and there the -court again stated the rule to- be:
“The burden of proof is upon the defendants to establish this defense. For the grant of letters patent is prima facie evidence that the patentee is the*441 lirst inventor of the device described in the letters patent and of its novelty. * * * Not only is the burden of proof to make good this defense upon the party setting it up, but it has been, held that ‘every reasonable doubt should be resolved against him.’ ”
It follows that we are clearly of the opinion that the defendants have not made out their defense that the device or process described in plaintiff’s patent was the result of mechanical skill, and not the product of inventive genius.
2. In support of the defense of anticipation, the appellants rely upon a patent for pavement issued to one John Murphy on March 8, 1881, a patent for concrete pavement issued to Thomas F. Hagerty on October 22, 1889, a patent for concrete pavement issued to George A. Bayard on April 24, 1888, and a patent for pavement or roadway issued to Frederick J. Warren on June 4, 1901.
The processes covered by these patents are readily and clearly distinguishable from the processes embodied in the Hassam patents. Under the Murphy patent the broken stone or slag is grouted before rolling. The first Hassam. patent calls for a “bottom layer of hard rolled uncoated stone.” In the Bayard patent the foundation consists of broken stone and ashes or pebbles, and a second layer consists of stone, cinders, and pebbles mixed with tar. Ashes, cinders, and tar play no part in the Hassam processes. In the Hagerty patent there is no preliminary hard rolling of the broken stone, nor is there any filling of the voids between the stones with grout. In the Warren patent no grouting whatever is used.
We have examined with care each of the prior publications, consisting of excerpts from encyclopedias, dictionaries, scientific notes, etc., introduced by the appellants and claimed by them to show anticipation. The rule is that a description in a prior publication, in order to defeat a patent, must contain and exhibit a substantial representation of the patented improvement in such full, clear, and exact terms as to enable any person, skilled in the art or science to which it appertains, to make, construct, and practice the invention patented. It must be
The decree of the court below is affirmed.
