Application No. 08/592,109
on the ground "with the rails vertically oriented relative to
the ground" and rotating the rails of the ladder system
relative to the ladder shoes at least 15 degrees as claimed.
Similarly, with regard to claim 13, we find no teaching in
Kiska of the steps of piercing a first rail with a first
curved slot while a first rail is oriented with its flange
facing up and piercing a second rail with a second curved slot
while the second rail is oriented with its flange facing down,
as required by the claim.
For all of the foregoing reasons, we shall not sustain
the examiner's rejection of claims 1 through 13 under 35
U.S.C. § 103 as being unpatentable over Kiska.
