Appeal No. 2001-0220 Application No. 09/244,044 find that the examiner has committed reversible error in dismissing the claim limitation concerning the dam and not establishing, prima facie, that the tundish/dam arrangement of Schmidt meets the claim limitation. As for the § 102 rejection of claims 30 and 31, we do not agree with appellants that the claim language "said dam having holes consisting essentially of a pair of holes substantially uniformly spaced across the width of said dam" provides a patentable distinction over Schmidt. We say this because it is not clear what meaning to ascribe to the language "substantially uniformly spaced across the width of said dam," i.e., does the language mean that each of two holes have to be equally spaced from the nearest side edge of the dam, or must the two holes be positioned at locations one-third and two-thirds of the width of the dam. Also, it is not clear to us that the claim language does not encompass any pair of holes depicted by Schmidt that are uniformly spaced across the width of the dam. However, we cannot sustain this rejection because appellant's argument that "there clearly and unequivocally is no teaching of the 25 mm-50% of the height of the dam limitation set forth in claim 30" (page 10 of principal brief, second paragraph) has not been addressed by the examiner.
