1.1 Global costs order or issue by issue - submissions
8 Camco relies on the observation of McHugh J in Oshlack v Richmond River Council (1998) 193 CLR 72 at [66] that the outcome of the case is "[by] far the most important factor which courts have viewed as guiding the exercise of the costs discretion", to contend that costs should be addressed having regard to the outcome of the case as a whole. Camco submits that, as the successful party in the litigation, costs should be awarded in its favour and concedes a discount of 20% to account for matters in which it was not successful.
9 Camco acknowledges that in patent cases the Court has in the past treated the claim for patent infringement and the cross-claim for invalidity as separate events and made separate orders with respect to the costs of the claim and cross-claim: see, eg, GlaxoSmithKline Consumer Healthcare Investments (Ireland) (No 2) Ltd v Generic Partners Pty Ltd (No 2) [2018] FCAFC 100 at [8] (per Middleton, Nicholas and Burley JJ); Damorgold Pty Ltd v Blindware Pty Ltd (No 2) [2018] FCA 364 at [56]-[61] (per Middleton J). Camco proposes that in the present case it is more efficient, and better serves the interests of justice (having regard to Camco's overall success in the litigation), that a single global costs order be made which addresses both the claim and the cross-claim. Such an approach was applied in Davies v Lazer Safe Pty Ltd (No 2) [2018] FCA 971 (per McKerracher J); Dometic Australia Pty Ltd v Houghton Leisure Products Pty Ltd (No 2) [2019] FCA 57 (per White J) (see in particular at [36]-[45]); Quaker Chemical (Australasia) Pty Ltd v Fuchs Lubricants (Australasia) Pty Ltd (No 3) [2020] FCA 515 (per Robertson J); and recently in TCT Group Pty Ltd v Polaris IP Pty Ltd (No 2) [2023] FCA 284 (per Burley J).
10 Camco highlighted the centrality of MMD's ore fines argument to the factual and oral evidence. Camco also noted that it had incurred additional unnecessary costs in responding to a substantial affidavit of Mr Mark Botes (405 pages), whose expert evidence (on infringement) was not ultimately relied upon. Camco prepared and filed responsive evidence from its expert Mr William Hunter, which was not required to be read given that MMD decided not to call Mr Botes. MMD indicated to Camco that it would not be relying on Mr Botes' evidence about a week after the Hunter evidence was served.
11 Camco submits that its cross-claim did not form a significant component of the trial. The trial was heavily devoted to questions concerning infringement. The invalidity issues were confined at trial only to two pieces of prior art for novelty and obviousness (which were reduced from the five originally pressed). Obviousness did not form part of the joint session evidence and minor arguments as to manner of manufacture, fair basis and clarity were raised solely due to MMD's construction of the claims.
12 In a table appended to its submissions, Camco estimated that the percentage of the evidence, transcript and judgment allocated to the issues on which it succeeded were: 77%, 83% and 71%, respectively.
13 As to reserved costs of the proceeding, Camco submits that it would simply occasion unnecessary complexity in the resolution of the question of costs for separate orders to be made for each interlocutory application. In any event, Camco submits that the mixed success of the interlocutory applications is accounted for in the proposed 20% discount to its costs.
14 In the interest of justice and efficiency, Camco does not press for a separate costs order for the cross-claim. Camco seeks for the global costs orders to encompass both the main proceeding as well as the subsequent cross claim, conceding that a discount to its costs of 20% is appropriate.
15 MMD concedes Camco should be awarded the bulk of its costs with respect to construction, infringement, the ACL claim and entitlement. However, in relation to construction and infringement, MMD contends that it is appropriate that a 35% discount should be applied to Camco's costs when awarding costs for the issues of construction and infringement, by reason of the following:
(a) MMD was successful with respect to the construction of the majority of the integers in issue between the parties.
(b) MMD incurred significant costs trying to accurately identify the design of each of Camco's tooth constructions. These unnecessary costs were incurred as a result of:
(i) significant inconsistencies and omissions in Camco's drawings and 3D models (including the presence of weld); and
(ii) Camco's failure to inform MMD of these omissions, despite MMD's request for such clarification.
(c) MMD sought admissions from Camco concerning the existence of welds and transmission of force within its tooth constructions. Camco did not admit the presence of weld between the rear covers of the First Yandi Constructions and Solomon Constructions. Camco also made no admissions regarding the transmission of force throughout each of the Camco Constructions. MMD maintains that it established each of these facts at trial and refers to the following paragraphs of the July Reasons to support this contention:
[314] Mr de Vos acknowledged that in the configuration depicted above, the force is transmitted via the welds and the forces down the side cover were going to be much greater than the forces into the rear face of the horn. Mr de Vos also acknowledged that the transfer of forces between the rear cover and the rear face of the support body would be much more effective if the two faces were flush, than if there was a gap of the kind depicted above.
…
[334] When questioned as to the configuration depicted in diagram 3, Mr de Vos acknowledged that, in terms of force, the forces down the side cover were going to be much greater than the forces into the rear face of the horn. Mr de Vos said the forces would, after exiting the weld between the rear cover and the side cover, take a 90-degree turn through the weld between the side cover and the rear face of the horn. As Camco submitted, no experiments were conducted by MMD which might have established the extent to which forces are efficiently transferred through to the support body, in accordance with Mr de Vos' construction.
…
[359] MMD relies on its transmission of forces argument to contend that each of the rear covers is seated in face to face contact with the rear face of the support body. In the case of the rear projection of the intermediate cover, forces can be transmitted directly as the rear projection touches the rear face of the support body, as well as indirectly via the welds. For the other rear covers the forces are transmitted indirectly through the welds.
…
[379] I do not consider that the front/rear faces of the intermediate cover are in face to face contact with the front/rear faces of the support body. There is no aperture in the front face of the intermediate cover as this is filled prior to installation. To the extent that there is any spill over penetration of the weld on to the front, side and rear faces, that is a minimal amount which does not result in the majority of the faces being in physical contact. Nor do I consider that the chamfers constitute more than a minimal part of the front or rear faces of the support body.
16 As to (c) above, MMD submits that ordinarily it would be entitled to its costs with respect to these matters. However, it notes that, for convenience, MMD is content for this aspect of its costs to be dealt with by way of a reduction in Camco's recoverable costs.
17 In response to MMD's submission that Camco's depictions of the tooth construction led them to undertake additional and unnecessary work and incur unnecessary costs, Camco argues it should not be penalised for the presence of welds not being included in the discovery drawings. Camco maintains that the presence of these welds was not redacted, or concealed, but rather never included in the drawings.
18 In addressing the Notice to Admit, Camco submits that it was critical of the form adopted by MMD and responded to this notice in a sensible and pragmatic manner, pointing out the ambiguities it said were present, and suggesting a series of facts that it was prepared to admit. Camco further adds that no relevant fact findings are established in [314] and [334] of the July Reasons. Indeed, these paragraphs reflect the findings and analysis of Mr de Vos. In addition, Camco states that [379] of the July Reasons comprises of findings favourable to Camco. I accept this assertion.
19 MMD also submits that it should be awarded its reserved costs in respect of the interlocutory applications on which it submits it was successful. Camco submits that the results of the interlocutory applications were mixed and that they should be included as costs of the proceeding as part of the single global costs order, subject also to the 20% discount.
