The evidence did warrant the conclusion which McLelland C.J. in Eq. reached that no bottom for a toilet pan had been made of the shape described before the date of the respondent's application for registration nor had there been earlier any publication of a description or representation of the bottom of a toilet pan of that shape. It was argued, however, that because an arrangement of the three sections of the design which has been described (that is, the rim, dome and the annular portion between them) was not indicated with any precision, the so-called design was altogether too vague to qualify for registration. The same contention was put somewhat differently in the form of an argument that any person inspecting the certificate of registration, although shown the features of the design, could not know the extent to which a different arrangement of those features would be protected by the registration of the design. The answer to these contentions lies, we think, in the recognition of what is essential to distinguish a design from a mere shape. It is, of course, true that every shape is not a design; there must be "sufficient individuality of appearance" to distinguish it from what Russell-Clarke in Ch. 2 of his book Copyright in Industrial Designs aptly describes as "the fundamental form" of an article. Furthermore, the existence of that sort of individuality is to be determined by the eye and not by measuring dimensions. It follows that a design need not have the precision of a working drawing; it concerns the shape or configuration of an article, as it appears to the eye. If a design applied by another has the features that are characteristic of the registered design and are so arranged that to the eye the resulting shape is substantially the same, there is infringement, whereas if the same features are arranged so that to the eye the resulting shape is different, there is, in the absence of fraudulent imitation, no infringement. In deciding one way or the other the proportions of common features may be of the utmost importance, but acceptance of this does not involve deciding that to be registrable the representation of the design must be represented so that its proportions can be accurately calculated; it is sufficient if it shows a shape with enough individuality of appearance to distinguish it and to enable it to be determined by visual comparison whether the shape of an article is either the same as, or nothing more than an imitation of, that disclosed by the registered design. If, for instance, a crescent were a new or original design for a light reflector, it could be registered although the representation depicted did not specify the degree of the curve, and if the question ever arose whether a reflector in the shape of a crescent but with a curve that by measurement was not the same as that represented would constitute an infringement, a comparison of the sort already indicated would then have to be made. Applying these principles to the shape of the bottom for a toilet pan that has been registered as a design, we consider that, taking the various features that are disclosed and their general arrangement, there is sufficient individuality of appearance to justify registration if the design was new or original.
