Application No. 09/131,386
distribution system that can implement copyright management and
charge management of the vended digital contents. According to
Appellants, the conventional digital contents distribution
systems are unable to flexibly designate the contents and
generate a trial-use version of them since not only the
expiration date, but also a range of available functions and data
that can be referred to, are restricted (specification, page 2).
As depicted in Figures 1-3, the first execution verify logic 7,
which is initially linked with the digital contents 8 to generate
the encapsulated contents 8, is replaced afterward with the
second execution verify logic. (specification, page 13). Thus,
the encapsulated contents 6 including the first execution verify
logic 7 is distributed as a trial-use digital contents with
restricted operation, whereas the execution verify logic
conversion software is distributed to replace the first execution
verify logic 7 with the second execution verify logic which has a
looser restriction (id.).
Representative independent claim 11 is reproduced below:

an author terminal for transmitting digital contents;
a copyright manager for carrying out copyright management of
said transmitted digital contents;
