preferably at least about 0.54." On page 8 of the
specification, it is indicated that "good torsion or
resistance to twisting in the portion of the frame most
subject to twisting" is achieved with a width of "at least
0.600 inch, more preferably at least about 0.620 inch, and
most preferably at least about 0.640 inch. With a W/L ratio of
"at least 0.500 and more preferably at least about 0.540 to
0.542," "good torsion (resistance to twisting) and good
stiffness (resistance to bending" is indicated. According to
appellants (specification, page 5), the illustrated cross
section of Figure 4 (4-4) has a length L of 1.181 inch and a
width W of 0.640 inch with the ratio of width W to length L
being 0.542. As revealed in TABLES I and II (specification,
page 6), width L and height W of cross sections above 4-4
progressively decrease toward the top section.
Appellants bring to our attention application Serial No.
569,348 (specification, page 7), which application matured
into the Garrett, Jr. patent now applied by the examiner. As
stated by appellants, in the 95 square inch model of the
