Appeal No. 1998-0575 Application No. 08/190,569 In the absence of sufficient factual evidence or scientific rationale on the part of the Examiner to establish why and how a skilled artisan would have arrived at the subject matter of claim 9, we find that the Examiner has failed to meet the initial burden of establishing the prima facie obviousness of the claimed subject matter. Accordingly, we are constrained to reverse the Examiner*s rejection of claims 9 and 10. -4-Page: Previous 1 2 3 4 5 6 NextLast modified: November 3, 2007
