Opinion

COLE, Judge.

The subject matter involved in this appeal relates to a design patent application for a building roof.

In proceedings before the Primary Examiner of the United States Patent Office, the single claim of the application was rejected, three grounds therefor being assigned. The Board of Appeals affirmed the examiner’s decision, reversal of the first ground of rejection, however, specifically being manifested.

The claim reads as follows:
“The ornamental design for a building roof substantially as shown and described.”

With the consent of the Patent Office, the application drawing has been supplemented on appeal by more accurate reproductions of the design in question and while technically not a part of the record before us, said reproductions will be considered in arriving at the decision of the court.

A clear description of applicant’s design is found in the opinion of the Primary Examiner, as follows:

“The subject matter of the instant application relates to a building roof made up of shingles of the type having granules on the surfaces thereof. Said granules are arranged in batches which vary in hue, chroma and value embedded in areas on the surface of the shingles with adjacent areas blended together so that when the shingles are laid on the roof an optical effect of deep shadows below the butts of the shingle units is produced simulating shingles of greater than actual thickness, the blending of adjacent areas of the granules of different hue, chroma and value arranged irregularly depthwise of the roof revealing a non-banding visual appearance laterally of *702 the roof of gradually deepening color value throughout the entire exposed area of each shingle unit from butt to overlap and the blending of the granules of different hue and chroma in areas laterally of the roof arranged irregularly widthwise in each shingle unit to reveal a non-banding appearance depthwise of the roof, the pattern of distribution of granules of different hue, chroma and value being different in each shingle unit.”

It is essential that the terms “hue,” "chroma,” and “value” (color value), used in the foregoing description, be understood. In this connection, the applicant has stated in his brief that eyery colored article, exclusive of black and white or intermediates there-between, has three qualities. Hue commonly means color, i. e., red, green, blue, yellow, or intermediates thereof. Chroma has particular reference to whether the hue is intense, weak, faded, etc. Color value is indicative of the degree of luminosity.

It appears to us that the applicant, by arranging areas of mineral granules on the shingles which vary in hue and chroma, but which gradually deepen in color value from butt to overlap, achieves the non-banding shadow blend roof effect which is claimed to be the essence of the invention. More concretely, the overall concept amounts to this: Constantly change the areas of different hue and chroma laterally of the roof and, at the same time, maintain a constantly changing color value vertically of the roof panel.

In rejecting the application on appeal, the Board of Appeals placed reliance upon the following references: McKay 1,208,595 December 12, 1916; House and Garden page 50 April, 1950.

The McKay reference is a product patent for prepared roofing while the latter publication is pertinent in connection with alleged copyright protection granted the present applicant covering the identical roof design claimed in the instant appeal.

Considering now the patent to McKay, the tribunals below predicated their rejection of the appealed claim on the ground that the subject matter thereof was not patentably distinct from that disclosed by the reference. That a product patent, such as the McKay reference, can, if pertinent, be cited as a disclosure to anticipate the design application on appeal is not disputed.

McKay’s drawing shows a shingle darker at the lap end which gradually becomes lighter at the butt end. The applicant agrees that the following analysis of the McKay specification, as set forth by the board in its opinion, is correct:

“McKay states that he attains fictitious or illusory shadow-values by the graduated blending or merging of a lighter-colored color-layer into the darker mass of a plastic main layer and that by the coordination of the resultant illusory ‘deep-shadow’ areas and ‘shadow-blends’ with the physical elevation and depressions of the prepared roofing surface, he attains the optical illusion of depth of relief which greatly exceeds the physical depth of the material. McKay also states that the two layers may be so blended as to graduate the color of the color coating into the dark appearance of the deep-shadow area in the resultant ‘shadow-blend’ areas. * * * ”

Concededly, McKay suggests a shadow blend giving an artificial appearance of thickness to the shingles. Persistently urging, however, that McKay’s idea was completely inoperative to produce anything which resembles the appearance of that inventor’s drawing, the applicant, to strengthen such a conclusion, has submitted the affidavit of one Howard Callahan, a man considered to be highly skilled in the art in question. The Callahan affidavit is clear to the effect that following diligent efforts to practice McKay’s invention, according to the tenor of the patent disclosure, the affiant was wholly unable to produce any likeness to the patentee’s drawing. A specimen piece of roofing allegedly made in accordance with the McKay process was placed in evidence. That it differs in appearance from the drawing of Figure 1 of the McKay patent is quite apparent.

*703 The sum and substance of applicant’s position would thus seem to be based on alleged inoperativeness of the McKay disclosure insofar as producing anything having the appearance of what is shown in the drawing of that patent. The applicant believes that “the draftsman made a mistake as to what McKay’s roll roofing would look like” and further that “it is purely a chance showing having no basis in the specification.” Applicant submits that justification for its conclusion is readily found in McKay’s failure to avoid “banding.” The applicant insists that it is only by varying the hue, chroma and color value of the granules that “banding” is avoided, and that McKay allegedly fails to achieve this result is, according to applicant, evidence of inoperativeness, regardless of what the reference drawing discloses.

In applying the McKay reference, the Primary Examiner said:

“ * * * the drawing disclosure of McKay clearly illustrates a shingle which is darker at the lap end and gradually becomes lighter at the butt end. It would appear that McKay accomplishes the same result as to appearance when his shingles are laid in a finished roof. Applicant, in support of his traversal of this rejection, has submitted a sample roof section alleged to have been made by the process outlined by McKay.
