Appeal 2007-2140
Application 09/892,790
Patent 5,917,679
platforms 110c and 110d together define a substantially
U-shaped projection that extends from the principle [sic]
surface 111 of the slider 100. The curvature of the cross rail 130
forms a negative pressure cavity 150, that may be somewhat
rounded, at the center of the slider body 100.
4. Appellants disclose the cross rail 130 may be formed of a series
of straight sidewall segments or alternatively may be a smooth curve
(Specification col. 6, ll. 35-38):
As shown in FIG. 6, the cross rail 130 may be respectively
smoothly configured without inner or outer corners, or it instead
may be formed by a series of connected straight sidewall
segments, or a combination thereof.
5. Appellants disclose that the cross rail extends from side to side
of the principal surface and thus the ABS (e.g. 110c) does not extend into
the center portion of the principal surface (Specification col. 6, ll. 54-57):
an interface region between the ABS rail 110c and the cross
rail 130 includes a stepped down surface portion 112 extending
between the ABS platform 110c and an edge of the slider
body 100 . . .
B. Prosecution history of the original application
6. On December 1, 1998, Appellants filed an Amendment that
in-part amended originally filed claim 1 and added new independent
claim 21 during prosecution of the patent for which reissue is sought.
