Appeal No. 96-1445
Application 08/371,684
transferred to Hornbeck’s approach utilizing a different
structural device. The same may be said of the subject matter
of dependent claims 17 through 24, which in turn reflect in
part the subject matter of previous claims just discussed.
Finally, the dichroic filters in dependent claims 25 through
32 are met by the teachings of Ernstoff and Hornbeck as
discussed earlier.
As thus amplified in this opinion, the examiner’s
position does not appear to us to be based on hindsight or
contrived from the reading of the subject matter of the
disclosed and claimed invention. It appears also that the
DMDs of Hornbeck are a structural analogue to the dichroic
mirrors of Ernstoff since each pixel 20 of Fig. 1A of Hornbeck
may deflect the beam 30 along hinges 34 and 36 as shown in
Fig. 2 of Hornbeck for a particular color representation to
the viewer. Appellants repeated reference to the book by Sze
relating to CCD devices is misplaced since it represents an
incomplete consideration of the teaching value of Collender
which does not merely teach CCD devices alone but CCDLCLV
devices combined from CCD devices and LCLV devices.
