"Section 226 appears to require the owner of a design right to establish that copying has taken place before infringement can be proved; that is similar to copyright. However the test of infringement is different. Under section 16 copyright will be infringed if the work, or a substantial part of the work, is copied. Under section 226 there will only be infringement if the design is copied so as to produce articles exactly or substantially to the design. Thus the test for infringement requires the alleged infringing article or articles be compared with the document or article embodying the design. Thereafter the court must decide whether copying took place and, if so, whether the alleged infringing article is made exactly to the design or substantially to that design. Whether or not the alleged infringing article is made substantially to the plaintiff's design must be an objective test to be decided through the eyes of the person to whom the design is directed."
