rolling and folding of the sheathing material without cracking or crumbling of the matrix.
The examiner argues that Webb’s statement that “[t]he composite coating 15 such
as ‘Icote’, can be varied in any number of textures including smooth, rough, gravelled, sand
blasted or trowelled and all made in a myriad of colors to suit the architectural design
needs of the building to which the panel is attached” (col. 2, line 64 - col. 3, line 1) indicates
that Icote was not meant by Webb to be the only material usable in his invention (answer,
pages 4-5 and 7-8). This statement, the examiner further argues, would have provided one
of ordinary skill in the art with motivation to optimize the proportions of the components of
the coating to obtain the desired aesthetic features (answer, pages 4-5). Although Webb
refers at the above-noted location to a coating “such as Icote”, Webb states that the
coating is “a composite coating 15, (known as “Icote”)” (col. 2, lines 30-31) and that “[i]n
the present invention, the exterior architectural surface features are provided in a coating
known as ‘Icote’” (col. 3, lines 39-41). Thus, the reference taken as a whole indicates that
the coating material used to make the wall panel system disclosed by Webb is Icote.
Webb teaches in the portion quoted above that the texture and color of the coating can be
varied, but Webb provides no teaching regarding making the coating flexible.
The examiner argues that in view of the teaching by Brouessard, it would have been
obvious to one of ordinary skill in the art to make Webb’s coated fibrous material flexible
and waterproof (answer, page 5). Brouessard teaches that his resin drops fix the fibers
