of the specification as to why an artisan would not have used
oriented strand lumber (OSL) as the flange material in any of
the I-beams of Scarlett, Onysko, or Brightwell.
In response to this argument of the appellant the
examiner states (answer, p. 5) that
Scarlett, Brightwell, and Onysko et al. teach utilization
of "oriented strand lumber" as chord [flange] members as
at col. 4, lines 23-25 of Scarlett or col. 3, lines 31-34
of Brightwell or col. 6, lines 29-33 of Onysko et al.
We have reviewed the entire disclosures of Scarlett,
Brightwell and Onysko, especially those passages cited by the
examiner, and fail to find any disclosure or suggestion
therein to use oriented strand lumber (OSL) as an I-beam
3The meaning of oriented strand lumber and the
differences between oriented strand lumber and other types of
engineered lumber are set forth on pages 3-4 of the
appellant's specification.
