Appeal No. 2005-2175 Application 10/104,383 adopted to provide a solid surface (col. 2, ll. 39-44, col. 9, ll. 50-51, col. 10, ll. 3-6 and col. 12, ll. 17-50). We find that Pitman would have disclosed to one of ordinary skill in this art a lighting system that includes a support 5 having a cover 8 that hides base 4, wherein these parts can be extruded from, for example, PVC compositions containing “color pigments” (e.g., col. 4, ll. 55-63, col. 5, ll. 51-53, col. 6, ll. 61-65, col. 7, ll. 30-48, and FIG. 1). We find that Nelson would have disclosed to one of ordinary skill in this art a laminated article which is a central core with interlocking male and female edges, a planar decorative surface and a lower planar surface, that can be used as flooring, wall coverings and ceilings, and wherein two sections of the flooring can be joined to form “a gapless seam” (e.g., col. 2, ll. 13-28, col. 4, ll. 29-34, col. 5, ll. 20-23). Nelson would have taught that the decorative layer can be formed from any material that can be attached to the central core, such as conventional polymeric solid surfacing laminates, wherein the decorative layer can be attached to the core by coextrusion of the core and decorative layer, wherein the extrusions can include an optional tie layer (col. 2, l. 52, to col. 3, l. 7, and col. 3, ll. 42-44). Nelson further would have taught that “it is possible to bevel the planar decorative surfaces of each of the male and female edges to provide an angled surface down to the point where the planar decorative surface meets the central core” which “would provide a grooved or notched seam upon joining adjacent sections” (col. 5, ll. 26-31). We find that Haid would have disclosed to one of ordinary skill in this art a panel structure comprising boards which can be used for, among other uses, a floor, in which a particular “T” shaped molding is used to join pairs of boards having grooves in opposing edges, wherein the “boards” can be made of “plastics” (e.g., col. 1, l. 41, to col. 2, l. 2, col. 3, ll. 19-55, col. 4, ll. 58-63, and Fig. 1). The examiner determines, with respect to appealed claims 67 and 68, that it would have been prima facie obvious to one of ordinary skill in this art “to color the cover layer of Pollock[, disclosed at col. 12, ll. 17-50,] with pigments as [Pitman] teaches the use of pigments to produce color in PVC layers” with respect to both claims (answer, page 6); to form the cover layer and the core of Pollock by coextrusion as taught by Nelson with respect to claim 68 (id., page 8); to join the planks of Pollock with the T-shaped molding of Haid for ease of installation with respect - 9 -Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
