underlie definition
underlie means “to lie or be situated under.” Ex. 3001. Although baffle 36 is positioned at a lower position than the “upper end opening” or “vent passage” identified by Petitioner, it is apparent from Figure 1 that no vertical line intersects both the baffle and the “upper end opening” or “vent passage.” The position of baffle 36 cannot be characterized fairly as “under” such an opening. Accordingly, we are not persuaded that Petitioner has demonstrated adequately that Ward discloses a “baffle means” that “underlie[s] said upper end opening” or that “underlie[s] said vent passage.”
