This finding is erroneous. A "header" refers to
identification or control information placed at the
beginning of a file or message, as contrasted with a
"trailer" which refers to information placed at the end. It
is clear that header 68 is associated with subsequent
blocks, two of which are the escape code block 70 and
block 72, and not with the previous blocks. Although
figure 3 shows a gap between header 68 and block 70, this
only means that one to three elementary units may be encoded
before the escape code, not that header 68 is functionally
associated with the previous blocks. That is, header 68 has
the same structure as header 42 and refers to subsequent
elementary units in the stream 38.
Second, the Examiner errs in finding that where the
escape code indicates elementary units crossing quadruple
boundaries, "the generated trailing byte header of the first
quadruple would indicate the actual positional
implementation of the escape code compression technique for
the specific elementary units in the subsequent quadruple"
(EA10), i.e., the trailing header follows the escape code.
As discussed in the preceding paragraph, there is no
