Appeal 2007-4310
Application 10/950,830
14. Mangum also notes that the characteristics of the polyvinyl chloride
are known to affect the characteristics of the foam coating. (Mangum
at 1:64-2:14.)
15. According to Mangum, all of these factors can be varied to achieve
different products to meet end-user requirements. (Mangum at 2:15–40.)
16. In certain embodiments, Mangum is concerned with two-scrim non-
slip pads in which the first and second foamed resin-coated scrims have
different properties. (Mangum at 3:1–15.)
17. For example, according to Magnum, Figures 5 and 6 depict a non-slip
pad 10 having a first scrim 12 that has, in the alternative, "very small holes
extending through the scrim, when coated with polyvinyl chloride liquid and
the liquid coating is cured about the first scrim 12." (Mangum at 4:15–19.)
18. Mangum further describes the second scrim 20 as having "alternating
apertures . . . when coated, the coating is not retained in the larger apertures,
but substantially coats the remaining portions of the second scrim 20. This
design has been found to provide an advantageous texture on its top surface
while providing good cushioning effects." (Mangum at 4:22–26.)
19. Mangum states that "[o]ther embodiments could utilize multiple
layers of the same and/or different scrim types." (Mangum at 4:22–26.)
The Examiner's Rejections
20. With regard to claim 1, the Examiner finds that "Mangum teaches a
multi-scrim non-slip pad comprising multiple layers of the same scrim types
wherein each scrim is substantially coated with a polyvinyl chloride coating
such that the coating is not retained in the larger apertures of the scrim for
