Appeal No. 2000-1269 Application 08/756,349 Maus discloses a honeycomb body of a catalytic reactor, and teaches that when there are alternating layers of smooth and corrugated sheet-metal layers, “it is suitable to reinforce some of the smooth sheet-metal layers. Smooth sheet-metal layers deform less under tensile strain than corrugated ones and can therefore transmit the resultant forces better than corrugated sheet-metal layers” (col. 2, lines 54-59). The admitted prior art relied upon by the examiner (answer, page 3) is the discussion of Maus in the appellant’s specification, wherein the appellant states that “preparing individual, different-thickness sheet-metal layers in the stack entails increased production cost” (page 2, lines 1-2) and that “[i]t is also fundamentally advantageous, for the sake of reducing the mass and expense of the honeycomb body, to make the sheet-metal layers as thin as possible. However, that objective contradicts the objective of high strength of the honeycomb body and long-term resistance to corrosion” (page 2, lines 6-11). The appellant refers to these excerpts as the appellant’s teachings (brief, pages 6-7), and the examiner has not 3Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
