Appeal No. 1997-1767 Application No. 08/442,959 As we discussed above, however, we find that the examiner has not provided the requisite factual basis upon which to assert that the enol form would necessarily be present in the keto-containing compound described in CA ‘566. Accordingly, the examiner has not met her initial burden of proof. Consequently, as in the rejection based on CA ‘389, we are not compelled to consider the sufficiency of the declaration of Dr. Lang. In summary, the examiner’s rejection of claims 11 and 12 under 35 U.S.C. § 102(b) as anticipated by CA ‘389 and the rejection of claims 11 and 12 under 35 U.S.C. § 103(a) as unpatentable over CA ‘566 are reversed. 9Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
