Opinion

Hatfield, Judge,

delivered the opinion of the court:

This is an appeal from the decision of the Board of Appeals of the United States Patent Office affirming the decision of the Primary Examiner rejecting the appealed claims, Nos. 21 and 22, in appellants’ application for a patent for an alleged invention relating to a “unit of structural material of uneven surface, and particularly,”' according to the specification, “to a rigid shingle with an irregularly corrugated surface.”

The invention is sufficiently described in the appealed claims, which read:

21. A preformed non-inflammable structural unit, adapted for use as a siding slab, sbingle, and the like, consisting chiefly of asbestos fibers and Portland cement and including, on the face thereof, elevated portions extending in irregularly longitudinal manner and to irregularly varying elevations, depressed portions alternating with the elevated portions and extending in irregularly longitudinal manner and to irregularly varying depths, and intermediate portions of irregularly sloping surfaces defined between the said elevated and depressed portions, whereby the unit is adapted to reflect light in diffuse-manner.
22. A rigid shingle comprising an end adapted to be exposed on its face to-view and another end adapted to be concealed from view in a finished roof assembly, the end adapted to be exposed having a rear surface that is substantially plane and having a face including elevated portions extending in irregularly longitudinal manner and to irregularly varying elevations, depressed portions alternating with the elevated portions and extending in an irregularly longitudinal manner and to irregularly varying depths, and intermediate portions of irregularly sloping surfaces defined between the said elevated and depressed portions and the said end adapted to be concealed from view having substantially plane front and rear surfaces.

Fischer, 1,584,023, May 11, 1926.

In its decision, the Board of Appeals made the following observation:

It is noted that applicants have proposed an amendment, changing the term, “unbroken,” or otherwise modifying each of the claims to substitute moldedf relating to the irregularities of the surface. The claims are being considered as with these amendments entered.

In explanation of the board’s statement, counsel for appellants state that—

[1134]*1134In copying these claims, we have inserted the limitation “molded”, because they were amended after the final rejection to include this word, and the Board of Appeals considered the claims as so amended (R. 18).

In his brief the Solicitor for the Patent Office states, in substance, that, although as “it formally stands of record in the application file” claim 21 does not include the word “molded,” in copying it he had inserted the word because the Board of Appeals had “actually considered the claim as if the word ‘molded’ had been entered therein * *

In their brief counsel for appellants state that—

Prior to the advent of the applicants’ invention, there was an unsatisfied demand in the building trade for a fireproof, waterproof shingle, which would make an inexpensive and durable covering for roofs or walls, which would not be shiny but would diffuse reflected light, which would not be broken or cracked by frost, which would simulate old weather beaten wooden shingles, and which would harmonize with the old Colonial types of architecture. The demand was not satisfied by anything known to the trade or by anything disclosed in the prior patents relied upon by the Patent Office,

and contend that, in order to meet the demand, appellants used a mixture of “hydraulic cement and reinforcing asbestos fibres” to “produce a strong, durable, waterproof, and fireproof shingle.”

It is conceded that the combination of materials used by appellants is old.

The feature claimed by counsel to lend patentability to appellants’ product is defined in the appealed claims as—

* * * elevated portions extending in irregularly longitudinal manner and to irregularly varying elevations, depressed portions alternating with the elevated portions and extending in irregularly longitudinal manner and to irregularly varying depths, and intermediate portions of irregularly sloping surfaces defined between the .said elevated and depressed portions.

The Scharwath et al. patent discloses a press molded asbestos cement shingle, the “exposed upper face” of which, according to the specification, is “ribbed or corrugated,” the surface being “broken by a plurality of substantially parallel longitudinally extending ridges * * * and by substantially transversely extending parallel curved intersecting ridges * * *, of comparatively small height * * * merely * * * sufficient to make pronounced markings or roughening of the surface.” Elsewhere the specification states that one object of the invention is to produce an article which will be free of “the glare ordinarily present in roofs of artificial shingle or tile.” The words “press molded” appear only in the claims of the reference.

The patent to Perry relates to a strip shingle in which a substantially homogeneous material is used. In his specification the patentee states that “the impressions are in the main or body por[1135]*1135tion of the construction strips, which has distributed therethrough the fibrous material, and which is of a homogeneous material capable •of receiving and permanently retaining impressions of the desired ■sort and not merely in any superficial coating on such strips”; that the depressions or grooves may be either straight or curved, and may be of any desired shape, depth, or width; that “It is, of course, to be understood that in the articles which are the object of my invention the) depressions are deep enough to provide of and by ■themselves the desired appearance of separate unit shingles or tiles without in any way relying on the use of pigmenting or similar materials of various classes to produce the desired effect.” After .giving various examples, the patentee states that “Any other desired form of groove or depression may be used”; that they may “be made by pressing the strip between rolls having projections corresponding to the depressions desired,” or they may “be made by hand or in any other feasible manner”; and that the depressed or corrugated portions, being of increased density “due to their having been compressed, act as mechanical strengthening members.”

The Putnam patent is for imitation shake.shingles, made of wood, having longitudinal grooves cut therein.

The patent to Fischer is for a fireproof shingle made of asbestos fibers and cement, such as Portland cement, combining together under hydraulic pressure.
