Appeal No. 94-3349
Application 07/757,085
is 2 micrometers and that the width of two elongated mask
openings which define the two grooves which form the L's is 1
micrometer (Col. 6, lines 29-33). With reference to Figure 5,
since the above stated dimensions indicate that the width of the
grooves which form the L's is 1 micrometer and the distance
between the adjacent L's is 2 micrometers, the length of the
groove which forms the bottom of the L, the shortest groove, is 4
micrometers. Moreover, the four-to-one ratio of length to width
is apparent by inspection. As Blonder also discloses that these
grooves can be protrusions and that the sidewalls can be
vertical, Blonder discloses strip shaped elevations.
Appellants argue that Blonder does not disclose strip-
shaped elevations which have a length which is at least four
times the width. As stated above, Blonder does disclose that the
grooves which form the two grooves of the L's depicted in Figure
5 may be replaced by protrusions which may have vertical
sidewalls. Further, in view of the disclosure in Blonder that
the width of the grooves is 1 micrometer and that the L's are 2
micrometers apart, Blonder clearly discloses that the length of
the shortest groove or protrusion is at least four times its
width. As such we do not find this argument persuasive.
