Consideration of fourth ground of appeal for period down to 17 June 2004
122 As will be recalled, s 77 uses the term corresponding design, which was defined in s 74 to mean a design that, when applied to an article, resulted in a reproduction of that work, but did not include a design consisting solely of features of two-dimensional pattern or ornament applicable to a surface of an article (see [84] above). At [86] above I set out the definition of "design" in s 4 of the Designs Act 1906 and s 18 of that Act which applied in this period.
123 The primary Judge addressed the concept of a "corresponding design" and noted (at [219]) that the term "design" was not defined in the Copyright Act but was defined in the Designs Act 1906. His Honour observed (at [221]) that in Edwards Hot Water v SW Hart & Co Pty Ltd (1983) 49 ALR 605, Franki J held (at 632) that before a design could be a "corresponding design" within Div 8, it must satisfy the definition of "design" within the Designs Act 1906. Similarly, the High Court noted in Burge v Swarbrick (2007) 234 ALR 204 (at [17]) that the term "design" in s 74 of the Copyright Act picked up the definition in the Designs Act 1906 (citing Muscat at 349). In similar vein, the primary Judge held (at [224]) that a design for the purposes of ss 74 and 77 of the Copyright Act is a design as defined by the Designs Act. In other words, there must be a design that fell within the definition of s 4 of the Designs Act 1906 before there could be a corresponding design, and before the s 77 exception can operate.
124 The primary Judge discussed the principles in relation to designs. At [225] and [226], his Honour stated:
[225] … the fundament of a design remains that there must be some aspect of visual appeal to the eye. It may well be that the features of shape serve a functional purpose or assist in making function efficacious but these attributes will not disqualify the features of shape or orientation as a design for the purposes of the Designs Act 1906 if the designer has selected features of shape or configuration or, put differently, "if there was room for choice by the designer" Hosokawa [Micron International Inc v Fortune (1990) 26 FCR 393] per Gummow J at FCR 429-30.
[226] As a result, it is not an infringement of the reproduction right comprised in the copyright subsisting in an artistic work to reproduce the work by applying features of shape, pattern or configuration derived by selection by the designer (author) notwithstanding efficacious functional contribution, to an article that when so applied, those features are capable of being judged by the eye in the finished article.
His Honour also stated (at [230]):
[230] The notion of appeal to the eye does not necessarily mean aesthetic appeal (although that may well be present in a particular design) but simply mean a "mental conception conveyed to the mind of the eye" (Dart Industries v Décor Corp Pty Ltd (1989) 15 IPR 403); in that sense, visual differentiation of shape is required. In some cases, the drawings potentially exhibiting a design may be complex such as detailed sectional engineering drawings and the features of shape may therefore be difficult to discern with the result that any element of appeal to the eye is solely based on the functional efficiency of the component…
125 The primary Judge's reasoning on the issue as to whether there was a relevant "design" in respect of the Pivot Arms is found at [229] and [230]:
[229] … it seems to me from an examination of each of the applicant's artistic works in suit and particularly those drawings for the components I have found to be original drawings, namely, drawings for the outside mounting bracket, inside mounting bracket and pivot arms comprising the pivot mechanism, that features of shape or configuration are apparent. … As to the pivot mechanism, there is no doubt that the outer pivot arm and cranked inner pivot arm assume the features of shape in very large part to give structural strength to the opening mechanism under hydraulic load. That design change was brought into existence as a result of complaints to Mr Pesch of failures in the bucket under load by users. Clearly, the pivot mechanism with its two arms exhibit features of shape. However, it seems to me that these features are more than a blend of industrial efficiency with visual appeal. These features are very substantially determined by the requirements of strength and configuration for a double arm mechanism to enable the applicant's 4 in 1 bucket to open and close under hydraulic static and dynamic load. The demands of function overwhelm the features of shape for such a utilitarian component of a utilitarian bucket.
[230] … Although the pivot mechanism exhibits identifiable features of shape, I am satisfied that those features, although they involve some minor element of shape selection, are almost entirely dictated by the utilitarian function that a pivot mechanism must perform in facilitating the separation of the front and back sections of the bucket. In respect of that component therefore, there is no relevant design.
126 It is apparent from [231] of the primary Judge's reasons that in [229] and [230], his Honour was addressing only the question of whether the drawings satisfied the first limb of the definition of design, that is, whether they exhibited "features of shape, configuration, pattern or ornamentation". In subsequent paragraphs, his Honour addressed the other limbs of the definition, namely, whether the features were applicable to an article (at [231] - [234]) and whether they were "capable of being judged in the finished article" (at [235]).
127 Digga submits that Hosokawa Micron International Inc v Fortune (1990) 26 FCR 393 (Hosokawa) and other authorities referred to by his Honour were concerned with the statutory concept of "design" as it existed prior to 1 April 1982 (in Hosokawa, the design was created in October 1972) and are therefore no longer relevant. At that time, the definition in s 4 was:
"Design" means an industrial design applicable, in any way or by any means, to the purpose of the ornamentation, or pattern, or shape, or configuration, of an article, or to any two or more of those purposes.
128 The Designs Amendment Act 1981 (Cth) replaced the definition of "design" in s 4 of the Designs Act 1906 and replaced s 18 of that Act. The definition of "design" became:
"design" means features of shape, configuration, pattern or ornamentation applicable to an article, being features that, in the finished article, can be judged by the eye, but does not include a method or principle of construction.
Importantly, prior to the amending act of 1981, there was no equivalent to the s 18 that was introduced by that Act and which provided:
An application for registration of a design shall not be refused, and a registered design is not invalid, by reason only that the design consists of, or includes, features of shape or configuration that serve, or serve only, a functional purpose. [my emphasis]
129 The Explanatory Memorandum for the Designs Amendment Bill 1981 stated in its outline:
The Bill introduces a new definition of "design" which is coupled with a new provision [clearly a reference to the proposed s 18], the combined effect of which makes it clear that design features which serve a functional purpose should not be taken into account when determining the registrability or validity of the design.
Similar words were used by the Hon D.S Thomson, Minister for Science and Technology, in the Second Reading Speech in the House of Representatives on the Designs Amendment Bill 1981 (Parl Debs, HR, vol 122, 7 April 1981, 1368) in which the Minister stated (at 1369):
This will allow registration of shapes which enable an article to perform a particular function. The function itself will not be registered, merely the shape or feature needed to achieve the function.
Clause 10 of the Explanatory Memorandum for the Design Amendment Bill 1981 that related to the proposed s 18 was:
This section makes it clear that a design may include features of shape or configuration that serve a functional purpose, and that the decision of the House of Lords interpreting the corresponding UK legislation in AMP Inc v Utilux [1972] RPC 103 [in which it was held that a shape chosen solely to perform functional requirements of an article did not qualify as a design] does not apply to the interpretation of the Principal Act.
130 As mentioned at [123] above, a design must fall within the definition of "design" before it can be a "corresponding design". However, there is no requirement that, in order to be a "corresponding design", a design must satisfy the other requirements of registrability (Greenfield Products Pty Ltd v Rover-Scott Bonnar Ltd (1990) 95 ALR 275 at 287). Norm submitted that s 18 is relevant only to the registrability of a design, and not the definition of "design", and that therefore s 18 has no relevance to the inquiry as to whether a design falls within the definition of "corresponding design". I disagree. Section 18 is an elaboration of the definition of "design" in s 4. It would be nonsense to consider the definition as insisting that features of shape or configuration not serve a functional purpose, and then to attempt to apply s 18 to the field of candidate designs for registration. Designs that s 18 would have saved would have been already eliminated from the field, and s 18 would be left with no work to do.
131 It follows that features of the finished article of the kind described in the definition of "design" in s 4 (as in force during the period down to 17 June 2004) will be features capable of falling within the definition of "design" unless they are "a method or principle of construction", and the fact that they include or consist of features of shape or configuration that serve only a functional purpose is not a disqualification. There was no suggestion that the features of shape of the Pivot Arms were a method or principle of construction (see his Honour's comments at [242]).
132 With respect, I do not think his Honour gave effect to the legislative change made by the Designs Amendment Act 1981 (Cth). His finding that "the requirements of strength and configuration" did "overwhelm the features of shape" did not resolve the issue before him in the light of that amendment. His Honour accepted (at [230] set out above) that the Pivot Arms exhibited "features of shape". Indeed, the primary Judge had earlier identified those features of shape as being both "original" and "visually apparent" when considering whether the drawings of the Pivot Arms were original works in which copyright subsisted. His Honour stated (at [127]):
As to the pivot arms (BC41-D015), I am similarly satisfied that the pivot mechanism is substantially different to the mechanism depicted in the drawing from the First Plans dated 30 August 1993 and that the work, labour, skill and effort by Mr Pesch in redesigning the pivot mechanism reflected in BC41-D015 is original and the changes are visually apparent.
The amendments made as a result of the 1981 Act make it clear that the fact that those features of shape also served, and were chosen to assist, a functional purpose, did not prevent those features of shape from falling within the definition of "design".
133 Furthermore, on the basis that the test proposed by Gummow J in Hosokawa (referred to by the primary Judge at [225] set out at [124] above) remains relevant to the question of design (contrary to Digga's submission noted at [127] above), there was "room for choice" in the shape and configuration of the Pivot Arms. In cross-examination, Mr Pesch agreed that the choice of the shape of the Pivot Arms depended on the designer's choice. In its submissions at trial in support of the originality of Norm's drawing of the Pivot Arms, Norm submitted:
It is...unique and novel and original in this sense and your Honour can test that by comparing it against the other brands of buckets that your Honour has had the opportunity of seeing.
Also, your Honour, it's not a component that can be said to be dictated solely by function. And this can be seen by the fact that there are various different designs of pivot mechanisms out there, all of which vary from those that you see in the Norm and the Digga bucket. So, for example, your Honour, if you look at the pivot mechanism in the Drott patent, and I've given you the reference there, it's quite dissimilar to the pivot mechanism used in the Norm drawings. And then, your Honour, in paragraph 73 I give other examples. Caterpillar and Daiken, all of which show differences.
134 With respect, I do not think it was open to the primary Judge to hold that there was no "design", and no "corresponding design" on the basis stated by his Honour at [229] and [230] set out at [125] above. There does not seem to be any reason why his Honour's findings (at [231]-[235]) as to the remaining limbs of the definition of design in relation to the drawings for the other components would not apply to the Pivot Arms. Therefore, in relation to the period down to 17 June 2004, Digga's appeal succeeds in relation to the three-dimensional reproduction of Norm's drawing for the Pivot Arms.
