Appeal No. 1999-1281 Application No. 08/712,249 Therefore, we agree with appellants (Reply Brief, page 8) that “[n]o prima facie case has been made out and therefore the burden has not properly shifted to [a]ppellants to provide evidence of unexpected superior results.” The initial burden of presenting a prima facie case of obviousness rests on the examiner. In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992). In our opinion, since the examiner’s combination of references fail to teach a heparin molecule having more than one metal salt thereon, the examiner has not meet her burden of establishing a prima facie case of obviousness under 35 U.S.C. § 103. Where the examiner fails to establish a prima facie case, the rejection is improper and will be overturned. In re Fine, 837 F.2d 1071, 1074, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988). Accordingly, we reverse the examiner’s rejection of claims 27-49 under 35 U.S.C. § 103. Having determined that the examiner has not established a prima facie case of obviousness, we find it unnecessary to discuss appellants evidence of unexpected results relied on by appellants to rebut any such prima facie case.
