last paragraph, and page 15, last paragraph). Maggard WO’762
does not describe the automatic injecting of the calibration
standards. Inman discloses an automatic fluid injection
device is capable of coordinating the sequence and entry of
desired parameter values for controlling the operation of
spectrophotometers. (Column 2, lines 47-53).
Spectrophotometric analysis of large number of samples is
performed more efficiently by the use of the automated fluid
injection device. (Column 1, lines 57-63). It would have been
obvious to one of ordinary skill in the art who performs
spectrophotometric analysis on a large number of samples to
incorporate an automatic injection device in the process of
Maggard WO’762 in order to obtain an efficient operation. The
measurement for PIANO content performed in Maggard WO’762 on
the multiple reference samples, shown in the examples, would
provide calibration of the spectrophotometer “over a range” as
required by claim 1.
Applicants also argue the combination of features
contained in claims 9, 10 and 11 provide a less obvious
combination. (Brief, page 16, line 15 to page 17, line 7).
