Appeal No. 1999-2259
Application 08/711,614
step in an anticipation analysis involves a comparison of the
construed claim[s] to the prior art. Id.
Construing claim 1, we note that the claim language
plainly requires at least the limitations of “a surge clamp”;
“an extruded form being cutable to a length”; “a number of
busway housings”; and “said surge clamp for continuously
engaging a generally flat surface of said any one of the
busway housings . . . .” Appellant’s specification
discloses that surge clamps are fastened to the top and bottom
of busway housings to limit or prevent damage to the housing
caused by high short circuit magnetic forces. Busway housing
includes a duct top, duct bottom, two generally parallel duct
sides extending along the longitudinal dimension of the busway
section and a number of surge clamps placed across the duct
top and duct bottom. Specification, page 4.
Comparing the prior art, Rinderer discloses a ladder-type
cable tray with rungs. Specifically, column 2, lines 32-35
reads:
The cable tray 20 comprises first and second generally
parallel spaced-apart metal side rails 22, 24 and a
plurality of metal rungs, each designated 26, extending
between the rails at intervals spaced along the rails.
