3.6.3 Consideration
76 A person infringes a registered design if the infringing product embodies a design that is substantially similar in overall impression to the registered design: s 71(1)(a). As the principles identified in section 2 above indicate, this involves a qualitative evaluation of the importance of the similarities and differences between the competing designs, focussing on the whole of the appearance, rather than counting the differences. It is necessary for the Court to apply the standard of the informed user within s 19(4) which, in the present case, has been assisted by the evidence of Mr MacDonald and Mr Simpson, having regard to the prior art. In considering this question I have taken into account the various matters set out in s 19, some of which I refer to explicitly below.
77 I have noted in section 3.6.2 the similarities and differences between the GME design and the XTRAK device. The overall shape of the XTRAK is very similar to the GME design in that both are vertically symmetrical curve-shaped trapezoids, tapering to the base.
78 One point of difference is that the XTRAK has a smooth silhouette whereas the GME design has a step-in in its lower third on its front and sides that follows around to the lower portion of the housing at the rear. Mr Simpson gave evidence in chief that he considered the step-in to be the "dominant visual element" of the GME design, because it creates the impression that the microphone is a constructed form consisting of two distinct components. He considered that the overall impression given by the GME design is that of a durable and technical design, and that this is primarily conveyed by the step. In cross examination Mr Simpson appeared to resile from this view, contending instead that it was the speaker that created a distinct difference between the more technical rarely used lower buttons, and the more frequently used upper buttons. He explained that he did not intend to identify the step as suggesting that the device was made of two components, but rather that the form creates a break between the upper and lower portions. Mr MacDonald disagreed with these views. He gave evidence that he "barely noticed" the step when he first saw the GME design.
79 Having regard to the whole of the design, and taking into account the evidence of the experts, I accept that the step-in is a design feature, but I do not consider that it is a strong, let alone the dominant visual element, of the design. It is one of the aspects that adds to the overall aesthetic, but does not have the effect for which Mr Simpson contends. This may particularly be seen from the isometric view, which demonstrates that the step is but a relatively minor aspect of the overall vertically-symmetrical curve-sided trapezoid, tapering to the bottom end. I consider the similarity of overall shape and silhouette to be important points likely to make a strong visual impression.
80 Turning to other aspects of the respective designs, the screen arrangement and screen surrounds are very similar. The PTT button is also very similar in both. This is a prominent feature, and one that is curved to blend in with the overall silhouette of the devices. The boss and grommet in both are very similar. The effect of these similarities is to accentuate the vertically symmetrical curve-shaped trapezoid shape of the XTRAK, which, as I have noted, is a significant aspect of the GME design. Another relevant similarity is the fact that both have clear spatial separation below the upper buttons and the lower buttons. In the case of the XTRAK, this is created by the first of the speaker grilles and the two dummy buttons, in the case of the GME design it is created by the speaker.
81 I consider these similarities against three more relevant differences. First, the smooth housing shape of the XTRAK compared to the GME design, which includes the step-in at its waist and extending around the device. Secondly, the arrangement of lower buttons around a central trapezoidal button in the GME design compared with the two columns of buttons separated by the central column of the speaker grille in the XTRAK device. Thirdly, the row of two dummy buttons and the central row of the speaker grille in the XTRAK compared to the speaker in the GME design.
82 Other differences and similarities are relatively trivial and I give them lesser weight. In the GME design there is a small recess for the microphone at the top, whereas it is concealed in one of 3 indentations in the XTRAK device. The arrangement of the top buttons is different in both, with the only button on the top of the GME design slightly protruding. The rear of the devices is very similar, although the informed user would, in my view, pay little regard to it.
83 Taking into account these similarities and differences, but placing more weight on the similarities between the designs than the differences as required by s 19(1), I consider that the XTRAK embodies a design that is substantially similar in overall impression to the GME design. In this regard I am particularly influenced by the similarities to which I have referred.
84 I take into account the state of development of the prior art in making my assessment, in accordance with s 19(2)(a) of the Act. In my view the informed user would regard the XTRAK to be more similar in overall impression to the GME design than any of the other prior art devices. The prior art base demonstrates that the overall shape of each of the devices considered in section 3.3 above varies considerably, from broadly rectangular, to trapezoidal, to the waisted rectangle of the Crystal. The two most similar to the GME design, in terms of shape, in the prior art are the TX4500S and the Standard Horizon, yet they have more obviously different appearances in terms of their front face arrangements.
85 The statement of newness and distinctiveness of the GME designs draws attention to no individual aspect to which "particular regard" should be given pursuant to s 19(2)(b).
86 Having regard to all of these matters, I assess that the XTRAK device is substantially similar in overall impression to the GME Design.
