Appeal No. 97-2243 Application 08/222,584 Rejections based on 35 U.S.C. § 103 must rest on a factual basis. In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 177-78 (CCPA 1967). In making such a rejection, the examiner has the initial duty of supplying the requisite factual basis and may not, because of doubts that the invention is patentable, resort to speculation, unfounded assumptions or hindsight reconstruction to supply deficiencies in the factual basis. Id. In the present case, Trower and Jaschek do not justify the examiner’s conclusion that it would have been obvious to one of ordinary skill in the art to laminate Trower’s intermediate layer 14 and outer wall 12 to one another. In short, the semi-rigid, self-supporting pool wall defined by Trower’s intermediate layer 14 and outer wall 12 and the highly flexible coated fabrics disclosed by Jaschek have little, if any, meaningful relevance to one another. The only suggestion to combine these two references in the manner proposed by the examiner stems from impermissible hindsight knowledge derived from the appellant’s own disclosure. Moreover, this deficiency in the basic Trower-Jaschek combination is not cured by the German reference which discloses a pool wall laminate consisting of a polyurethane foam core sandwiched between polypropylene liners. -5-Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
