Appeal No. 2001-0786 Application No. 09/089,575 Appellant further argues that the proposed "reconstruction" would have the effect of removing the overlapping feedhole structure in Duerr and require delivery of batch material directly from the compound feed section to the slots as in Kragle. See Brief, pp. 8-9. However, one cannot show nonobviousness by attacking the references individually where the rejection is based on the combined teachings of the references. As explained by the Court in In re Keller, 642 F.2d 413, 425, 208 USPQ 871, 881 (CCPA 1981): The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art. Therefore, it is of no moment that batch material is delivered directly from the compound feed section to the discharge slots in Kragle or that the compound feed section in Kragle does not have an overlapping feedhole structure. The examiner merely relied on Kragle for its teaching of forming a compound feed section in a multilayer structure. Based on the record before us, we find the facts on which the examiner’s conclusion of obviousness was based to be of 7Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
