Can an ISP be liable for Copyright Infringement for users who use their service to browse on the Internet?
Possibly. A copyright holder of an article or photo which he or she places on the Internet with the intent and desire that it is to be browsed, gives the viewer the implied license to browse and print-out a copy if the material. Such, is subject to the fair use doctrine. If a person’s browser prints-out an article or photo that was placed on the Internet without authorization is protected and considered an innocent infringement.
