Appeal No. 97-4249 Application No. 08/249,400 apparatus (Figure 1) and the inventive apparatus (Figure 3), utilize a pair of serpentine heat exchangers, with the improvement provided by Oogushi being the use of full length plates 11 (Figure 3) rather than partial length plates 8 (Figure 1). The teachings of the other references applied against independent claims 11 and 16, as well as against various of the dependent claims, fail to alleviate the deficiencies pointed out above. It is our conclusion that the teachings of the references applied against independent claims 1, 11 and 16 fail to establish a prima facie case of obviousness with regard to the subject matter recited in each, and we therefore will not sustain the rejections of these claims or of the others, all of which depend from them. 9Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
