The Copyright (Amendment) Ordinance 2004 introduces a new offence, which is known as the "copyshop offence", into the Copyright Ordinance. Under the copyshop offence, a person would be criminally liable if, for the purpose of or in the course of a copying service business, he possesses an infringing reprographic copy of a copyright work as published in a book, magazine or periodical. It is important to note that it has all along been an offence for any person (including a copyshop) to make for sale or hire an infringing copy of a copyright work without the permission of the copyright owner. Under this existing offence, the prosecution is required to prove the making of an infringing copy by a copyshop, which can be difficult to establish. The copyshop offence is introduced to facilitate enforcement and prosecution work against illicit reproduction of books, magazines or periodicals by copyshops for the purpose of or in the course of their business.
