Appeal No. 2002-2090 Application 08/430,311 On page 17 of the specification, appellant indicates that the invention being taught is a load bearing concrete panel structure which uses structural plain concrete for at least the upper portion of the panel, which concrete has, in preferred embodiments, been specially formulated and installed in a manner to resist temperature change and concrete shrinkage cracking at the upper surface, and which relies on flexural reinforcing materials, such as standard flexural reinforcing bars, being confined to the lower half of the panel to carry superimposed loads. Different practices envisioned by appellant for improving upper surface crack control are taught in the paragraph bridging pages 19-20 of the specification. On page 21, lines 18-21, it is noted that “[i]n preferred embodiments, a minimum of reinforcement material, such as fiber or fabric may be disposed in the panel, preferably in about the upper one-third to one-half portion of the concrete layer to provide control of cracking due to temperature change and concrete shrinkage.” Independent claims 57, 70, 72 and 74 are representative of the subject matter on appeal, and a copy of those claims is attached to this decision. 3Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
