Appeal No. 1999-0587
Application 08/414,803
accordance with the various command information just discussed, operations are
performed upon the pixels in accordance with various attributes to be attributed to them.
This attribute information relates to the extent of pixel transparency and/or translucency,
color and Z values. In association with the discussion related to Figures 6 through 9
beginning at the bottom of column 4 of this reference to the end of the patent, there is
indicated that in effect the various draw commands associated with the respective pixels
can set forth relationships between the pixels and attributes associated with the respective
pixels such as to encompass the broadly recited mixing ratio selection of the claims on
appeal. It thus appears that the PERAM also may be analogous to the claimed mixing
ratio memory such that the commands from the sequencer SEQ and micro control memory
U are in effect the claimed mixing ratio selection information in the drawing commands as
claimed.
We thus conclude that Evangelisti in his own words does teach the claimed mixing
ratios selection information even though, as the examiner notes in the statement of the
rejection at pages 3 and 4 of the answer, this reference does not explicitly use the same
words to express the same feature. The examiner then in turn properly relies upon Kirk
which, even in the abstract, indicates that control data associated with controlling the
operation of the mixer circuit 8 in Figure 1, for example, feeds it control information for
generating display pixel data comprised of a combination of proportions of the data in the
