elements, all arranged as claimed." (Paper 21 at 3.) This
finding is consistent with Rammos' subarrays. (5:44-58;
Figs. 9-11.) Consequently, the preponderance of evidence
supports the examiner's rejection of these claims.
Claim 10 recites a frequency ("approximately 12 GHz") and
a specific concavity spacing (5 mm). One-quarter wavelength
at 12 GHz is 6.25 mm. (Rammos 5:12-13.) Rammos discloses
only a 12 GHz array. Thus, a person having ordinary skill in
the art would have been motivated to apply any of Rammos'
embodiments to a 12 GHz array. Rammos teaches the use of a
spacing distance between the printed circuit and the ground
plane, H (4:4-6), such that H is at least 1 mm andL L
"about / ", which at 12 GHz is 6.25 mm. (5:7-17.) The8

teaching of about is sufficient to motivate a person having
ordinary skill in the art to optimize H starting at 6.25 mm.
L
Since thickness is a matter of concern in the art, the artisan
would have been motivated to find an effective value below
6.25 mm. To the extent there is any criticality associated
