Appeal No. 95-3185
Application 08/129,029
Moreover, in the background section of the applicants’
specification, it is acknowledged that it has been known to
record digital audio signals in compressed form. While
Yamaguchi does not expressly state that the digital audio
signals on the master disk are in compressed form, it cannot
be reasonably argued that one with ordinary skill in the art
would not have recognized that the stored signals can be in
compressed form.
Furthermore, the applicants are estopped from arguing
that Yamaguchi’s stored signals are not in compressed form.
In the appeal brief on page 9 and in connection with
Yamaguchi’s disclosure, the applicants state "conversion of
the bit compressed data from the [Yamaguchi] master disk to a
form which could be audible to a user, i.e., by decompression,
expansion, etc. requires considerable time as opposed to
direct recording without decompression and expansion, so that
monitoring the mastering progress would just slow it down for
no good reason." Thus, the applicants themselves have assumed
that the recorded signals on Yamaguchi’s master disk can be in
compressed form.
