The Global/Impact parties
20 We will first consider the position of the Global/Impact parties with respect to the costs of the proceeding excluding the costs of the remittal hearing.
21 The principal focus of the proceeding until the first of the Full Court decisions was on the allegations of copyright infringement which the Aristocrat parties made against all six respondents.
22 The case against the Global/Impact parties was that they were each knowingly concerned in copyright infringement on an enormous scale. Very substantial damages were sought by the Aristocrat parties pursuant to s 115(4) of the Copyright Act 1968 (Cth) ("the Act") from each of the Global/Impact parties on the basis that their infringements were flagrant. The copyright case against the Global/Impact parties was wholly unsuccessful.
23 In their submissions, the Aristocrat parties contended that the overwhelming focus of the proceeding (excluding the remittal hearing) as between the Aristocrat parties and the Global/Impact parties was the factual contest as to whether the joint venture had in its possession counterfeit gaming machine components and whether the joint venture sold machines that contained such components.
24 However, it is clear that there was another important factual contest which concerned the issue of knowledge, including, in particular, whether the Global/Impact parties knew, or ought to have known, that the gaming machines sold to their South American customers included counterfeit EPROMs and counterfeit compliance plates. The Aristocrat parties were wholly unsuccessful on those issues.
25 There are other matters that must be considered when determining what is the appropriate orders for costs:
The Aristocrat parties alleged that a total of 618 gaming machines included "counterfeit" compliance plates and EPROMs but were only able to make that allegation out in relation to a comparatively small number of machines.
The Aristocrat parties also advanced a case based upon the tort of conversion that was rejected.
The Aristocrat parties also advanced a case of copyright infringement based upon artwork. That case was abandoned shortly prior to final submissions.
The Aristocrat parties also advanced a case under s 52 of the Trade Practices Act 1974 (Cth) and for passing off that was not pressed.
A considerable amount of time and expense was devoted to the Aristocrat parties' data matching evidence, which the primary judge found to be unreliable and of no assistance.
26 As to the data matching exercise, the primary judge said in his judgment of 8 March 2010 at [10] that "the data matching exercise was an enormous one and … a huge amount of time and painstaking effort was put into meeting that part of the Aristocrat companies' case."
27 The Aristocrat parties succeeded in obtaining injunctive relief in respect of a number of their trade marks (including the Aristocrat word marks) against the Global/Impact parties over what was at all stages of this litigation forceful opposition from the Global/Impact parties. The Aristocrat parties are entitled to their costs of that aspect of the proceeding recognising, at the same time, that for them the trade mark infringement case was a fall back case that was only faintly argued, and that did not result in the award of any damages, much less the very substantial damages that they had sought.
28 We are mindful that the principal case that was advanced by the Aristocrat parties was one of copyright infringement no doubt because it might, if successful, result in an award of substantial damages pursuant to s 115(4) of the Act. The copyright case against the Global/Impact parties failed in its totality. The modest success achieved by the Aristocrat companies on their trade mark claims against the Global/Impact parties was limited to an award of declaratory and injunctive relief.
29 On the other hand, we accept the Aristocrat parties' submission that, so far as the factual allegations were concerned, there was a considerable amount of overlap between the copyright case and trade mark case. In particular, in order to succeed in their claims for trade mark infringement, it was necessary for the appellants to establish that one or more of their registered trade marks was applied, without their consent, to second-hand gaming machines that were exported by the joint venture, and that included counterfeit EPROMs and compliance plates.
30 We do not think the costs orders proposed by either the Aristocrat parties or the Global/Impact parties are appropriate in the circumstances of this case. We have given consideration to other forms of orders including, in particular, an order that each party pay its own costs, but in our view an order to that effect pays insufficient attention to the scope of the Global/Impact parties' overall success and the very limited relief obtained against them compared to the scale of the case that the Aristocrat parties set out to prove.
31 All things considered, in our opinion the preferable order is that the Aristocrat parties pay 50% of the Global/Impact parties' costs of the proceeding excluding the remittal hearing.
