The Court indicated that, in order to determine whether the reproduction of a
copyrighted work conflicts with the normal exploitation thereof and is unreasonably prejudicial
to the legitimate right of the copyright owner, it is necessary to consider the circumstances on a
case-by-case basis, involving an examination of the factors of quality and quantity. In
determining the issue of whether the quantity of duplication is a reasonable amount, the Court
acknowledged the difficulty in interpreting the two conditions. The exception allows for the
reproduction of copyright works for research or study which is not for profit, provided that the
two conditions are satisfied; but it does not set a clear limitation as to the amount of
reproduction, nor does it prohibit multiple reproductions of copyrighted materials.
