Our research concluded that both buyers and sellers are prepared to accept a universal standardized copyright notice, together with standard procedures for displaying them. It is not clear to what extent copyright holders agree on the extent to which buyers and end-users may make use of copyrighted information over networks. It is also recommended that the copyright notice mark appear immediately upon accessing a file and that prior to downloading the end-user be cautioned about restrictions imposed on copyrighted material. Certainly it is best that copyright holders defend their rights by introducing copyright notices in order to guard against indiscriminate use of material without just compensation. From a legal perspective, the display of copyright notices can benefit copyright holders in the event of unauthorized use.
Sellers can then use the force of law to defend their rights.
The appearance of copyright notices in appropriate sequence, on the correct screen and even with the clearest language, does not prevent users from willfully or in ignorance, making use of copyrighted material without compensation to the sellers.
