Appeal No. 2005-0564 Application No. 09/732,787 admitted prior art and Gerrans (brief, page 7). However, the Examiner’s discussion of Hauchard and its teachings related to the concave grooves and convex ribs as well as the desirability of providing structural strength without added material (answer, page 4) also reasonably support a prima facie case of obviousness. Therefore, the 35 U.S.C. § 103 rejection of claims 6 and 8 over the admitted prior art, Gerrans and Hauchard is also sustained. 8Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
