Appeal 2007-3148
Application 10/638,885
extensions 56a and 56b do not extend around the perimeter of the body and
so do not define an encircling lip (Br. 5).
We have considered Appellants’ arguments and are unpersuaded for
the reasons below.
Meyers discloses a trench drain system 20 (i.e., body) that includes a
U-shaped drain member 24 that has a three-dimensional outline with height,
width and depth and defines a drainage channel 50 (i.e., open interior)
(Meyers, Figures 1 and 2, col. 3, ll. 43-67). Meyers further discloses that the
drainage channel 50 (i.e., open interior) is adapted to be positioned (i.e.,
drain opening 27 with pipe connector flange 58 permits the U-shaped drain
member to surround the pipe 42) so that the drainage channel 50 (i.e., open
interior), via the pipe connector flange 58, surrounds the pipe 42 (i.e.,
exposed floor drain) (Meyers, Figure 2; col. 4, ll. 64-67; col. 5, ll. 1-2).
Meyers further discloses that a plurality of nails 148 (i.e., ground
securing fasteners) are engaged with the ground through base members 56a
and 56b (i.e., lower-most extremities associated with said body) (Meyers
Figure 12, col. 10, ll. 10-15). Meyers’ trench drain system 20 (i.e., body)
composed of U-shaped drain members 24 with the connector flange 58
isolates the end of the pipe 42 (i.e., the floor drain) from the encircling and
poured concrete C, which adheres against exteriorly facing surfaces (i.e.,
56a, 56b, 52a, 52b) of said body (Figures 1 and 2).
Regarding claim 2, Meyers discloses that when the desired trench
drain length is achieved, end caps 110 and 94 are placed on both ends of the
trench drain system 20 (Meyers, col. 10, ll. 30-35). Once the end caps 110
and 94 are placed on the trench drain system 20, the base extensions 56a and
56b form a closed and encircling lip as claimed.
