Appeal No. 1999-1101
Application 08/727,125
Demetriades-Shah compares measurements of crop reflectances
taken from a conventional nadir view (vertically downward
looking) against reflectances taken at an oblique angle.
Canopy reflectance from a downward view includes the influence
of soil visible between the plants and is primarily sensitive
to the relative amounts of soil and green vegetation in its
field of view rather than the greenness of canopy leaves
(p. 1055). There is a strong correlation between reflectance
measurements and chlorophyll content per unit ground area, but
poor correlation between reflectance measurements and
chlorophyll per unit plant weight for downward-looking
measurements (p. 1051). Demetriades-Shah concludes "that
plant chlorophyll concentration is better predicted from
oblique-looking reflectance measurements than from vertically
downward-looking measurements, because the influence of soil
reflectance is removed" (p. 1055).
THE REJECTIONS
Claims 1, 3, 7, 9, 13, and 17-21 stand rejected under
35 U.S.C. § 103(a) as being unpatentable over Monson,
Demetriades-Shah, and Peterson.
