Restrictions imposed under Section 56 of the Ordinance, the buyers of computer programs may not copy or make copies of the programs by themselves or their employees. The illegal use of a computer program in a computer is also an infringement of the copyright. Similarly, if a duplicate of a computer program is required by someone who has no license to use it, the copyright owner has the right to stop him using it. Section 56 also restricts the rental of computer programs to unauthorized users. Intention to copy computer programs is not an essential ingredient of infringement; nor is it essential that the copying is in the same medium. Thus, a computer program stored on diskettes can be infringed by copying the same on paper or taking a print-out of the same.
