second axially extending dimension” as including any axially
extending measurement of the passageway end taken near the
edge of the passageway end opening.
Reading independent claim 3 on the Figure 4 brake rotor
of Soltis, we find that the Figure 4 brake rotor comprises an
annular mounting flange and an annular friction disk having a
generally elliptical air passageway extending radially
therethrough. The outer end of the passageway has a first
center axially extending dimension (A1) and a first
circumferentially extending dimension (A3), and the inner end
of the passageway has a second center axially extending
dimension (B1) and a second circumferentially extending
dimension (B3) such that (B1) > (A1) and (B3) < (A3), as
required by claim 3. Moreover, based on our above
interpretation of the claim terminology “a first axially
extending dimension” and “a second axially extending
dimension,” we find that the Figure 4 passageway of Soltis has
a first axially extending dimension (A2) as measured near the
edge of the outer end of the passageway and a second axially
extending dimension (B2) as measured near the edge of the
inner end of the passageway, such that (A2) < (A1) and (B2) <
