Appeal No. 1999-2235 Application No. 08/577,493 examiner has provided no line of reasoning why such a relationship would have been obvious. As the examiner has not accounted for each and every element of the claims, the examiner has failed to establish a prima facie case of obviousness. Consequently, we cannot sustain the rejection of claims 1 and 14, nor of their dependents, claims 2 through 6, 8, 10, and 15 through 20. Regarding claim 7, the examiner adds Frey to the combination of Chapman and Hamilton. However, Frey does not cure the above-noted deficiency of the primary combination. Accordingly, we will not sustain the rejection of claim 7. 6Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
