(specification, page 3, line 26 to page 4, line 4). The
specification indicates that error correction codes and time
interleaving are used in the present invention (specification,
page 4, lines 10-14, before amendment): "Thus, all
information to be transmitted, consisting of, for example the
interleaved coded information (i.e. the useful information is
interleaved in time after the addition of an error correction
code), is divided into slots which are referred to herein as
replicas, said replicas undergoing the time multiplexing
operation so that the use of excessively deep time
interleaving is avoided." Manifestly, the encoded and
interleaved information must be deinterleaved and decoded
after transmission. Accordingly, we disagree with the
examiner's rejection to the extent it finds that the original
disclosure does not provide written description support for
the functions of encoding, interleaving, deinterleaving, and
decoding.
In regard to the structure for performing the functions,
and the exact type of encoding used, appellants argue (Br7):
[T]he "specific improvement" is the dispersion of
information, not its coding, interleaving, deinterleaving
or decoding. Nothing in the specification or claims
suggests that the invention involves or requires a new or
