Appeal No. 1997-0276 Application No. 08/357,641 outer wall of Mattice. No purpose, articulated by the examiner, or otherwise, would be served by an extension of the tarp or awning. Accordingly, the rejection is not well founded, and we will not sustain the rejection of claims 8 and 9. Turning to a consideration of claim 10, we note that the extendable unit therein claimed does not rely on any fenestration for patentability. As noted supra, Mattice shows, particularly in Figure 9, a tarp 128 and roller 130. We note from the Figure that roller 130 extends at an elevation higher than the horizontal top wall of the extendable slide-out unit. Turning to a consideration of Boyer, Boyer shows a retractable fabric roof for an automotive vehicle in which the take-up roller 23 is mounted at an elevation lower than what could be said to be the horizontal top wall. The examiner is of the view that it would have been obvious to mount the roller of Mattice below the horizontal top wall so that the position of the roller would be more easily accessible for cleaning and maintenance. We are in agreement with the examiner that Boyer would have been suggestive of mounting the take-up roller 130 of Mattice in 7Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
