As evidence of obviousness of the claimed subject matter under 35 U.S.C. § 103, the examiner relies on the combined teachings of Touval, Breitenfellner and Sandler. The examiner relies on Touval to demonstrate that dehydrating a mixture of a hydrated sodium antimonate and a certain polymer during the production of a flame proofing or fire retardant would have been obvious to one of ordinary skill in the art. See Answer, page 5-8. The examiner then relies on Breitenfellner and Sandler to establish that the use of the claimed specific polymers and other ingredients in the process of Touval would have been obvious to one of ordinary skill in the art. See Answer, pages 6-8. However, as indicated by appellants at page 4 of the Reply Brief, Touval does not teach dehydrating a mixture of a hydrated sodium antimonate and at least one polymer. Touval teaches drying the hydrated sodium antimonate prior to incorporating it to a polymer formulation for the production of a flame proofing or fire retardant in an extruder. See, e.g., column 6, line 3, column 7, lines 50-53. Although the examiner appears to argue that Touval inherentlyPage: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
