Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 11 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Kunitz in view of Patrick (US 5,657,967). As to claim 11, Kunitz fails to disclose a modular fence system wherein each of the first tab and second tab comprise an aperture, and wherein the modular fence system comprises a second plurality of fasteners, each of the second plurality of fasteners configured to extend through the apertures in the first tab or second tab and into one of the first and second vertical posts to secure the first horizontal support to one of the first or second vertical posts. Patrick teaches a modular fence system wherein a first horizontal support 16 comprises a first tab 25 comprising an aperture 28,30,32, and wherein a plurality of fasteners 34 are configured to extend through the apertures in the first tab and into one of a first and second vertical posts 12 to secure the first horizontal support to one of the first or second vertical posts; the apertures in the tab enabling the horizontal support to be affixed to greater variety of vertical posts utilizing a conventional fastener (Figures 1-4). Accordingly, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fence system disclosed by Kunitz wherein each of the first and second tabs comprises apertures, as taught by Patrick, in order to enable the horizontal support to be affixed to greater variety of vertical posts utilizing a conventional fastener. As to claim 12, Kunitz as modified by Patrick discloses a modular fence system wherein the aperture (28,30,32 Patrick Figure 3) in the first tab 18.1 and the aperture (28,30,32 Patrick Figure 3) in the second tab 18.1 are disposed at an aperture distance, DA, from the first end, wherein the first horizontal support 14 is configured such that the first horizontal support and one of the first and second vertical posts 12 form a gap when the first horizontal support is secured to and extending orthogonally from one of the first or second vertical posts, wherein the gap has a gap width, WG (Figures 1-11). Kunitz as modified by Patrick fails to explicitly disclose a fence system wherein WG/DA ≥ 0.06. Applicant is reminded that a change in the size of a prior art device, wherein there is no structural or functional significance disclosed as to the specific size of an element, is a design consideration within the skill of the art. In re Rose, 220 F.2d 459, 105 USPQ 237 (CCPA 1955). Accordingly, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the fence system disclosed by Kunitz as modified by Patrick wherein WG/DA ≥ 0.06, as such change in size is a design consideration within the skill of the art that would yield expected and predictable results; and as it would be expected that one of ordinary skill in the art would routinely experiment to arrive at the optimum or workable dimensions for a given application. Claims 15-17 are rejected under 35 U.S.C. 103 as being unpatentable over Cofield in view of Walker Industries (GB 2 298 439). As to claims 15-17, Cofield fails to disclose a modular fence system wherein the first vertical panel comprises a second protrusion extending from the first securing recess oppositely from the first protrusion and a third protrusion extending from the second securing recess oppositely from the first protrusion; and a first edge extending from the second protrusion oppositely from the first securing recess and a second edge extending from the third protrusion oppositely from the second securing recess, and wherein the first and second edges comprise an open hem. Walker Industries teaches a modular fence system wherein a first vertical panel 2 comprises a second protrusion 7 extending from a first securing recess 3 oppositely from a first protrusion 6 and a third protrusion 7 extending from a second securing recess 3 oppositely from the first protrusion; and a first edge extending from the second protrusion oppositely from the first securing recess and a second edge extending from the third protrusion oppositely from the second securing recess, and wherein the first and second edges comprise an open hem; the second and third protrusions providing for greater rigidity of the vertical panels (Figures 1-3). Accordingly, it would have been obvious to one having ordinary skill in the art before the effective filing of the claimed invention to modify the fence system disclosed by Cofield wherein the vertical panels comprise second and third protrusions, as taught by Walker Industries, in order to provide for greater rigidity of the vertical panels. Claims 1-9, 13 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Cofield in view of Simioni (US 6,152,428).
