Appeal No. 1999-1101
Application 08/727,125
taken into consideration, but do not address the teachings of
the references (Br17). Peterson discloses that the measured
value of chlorophyll (and, hence, the amount of nitrogen in
the plant) for an adequately fertilized crop in the reference
strips (the standard for a crop) changes in response to crop
and environmental conditions which is the reason for reference
strips to calibrate the bulk field readings (paragraph above
"Field Use of the Chlorophyll Meter" and under "Establishing
Reference Strips"). Thus, Peterson teaches that the reference
value changes in accordance with a changing standard for the
crop. The rejection of claim 19 is sustained.
Claim 20 depends on claim 19 and recites that the
changing standard is electromagnetic radiation affected by a
reference crop in the same stage of growth. Appellants argue
that this requires that electromagnetic radiation must be
affected by different stages of growth, but do not address the
teachings of the references (Br17). Peterson discloses that
the amount of measured chlorophyll (hence, the amount of
nitrogen in the plant) is affected by environmental conditions
and discloses the use of reference strips of crops in the same
stage of growth as a changing standard for chlorophyll
