Costs
5 This brings me to the issue of costs.
6 While the Court's power to award costs under s 43 of the Federal Court of Australia Act 1976 (Cth) (the "FCA Act") is broad and unfettered, it is to be exercised judicially and in accordance with well-established principles. As stated by French CJ, Hayne, Bell, Gageler and Keane JJ in Gray v Richards (No 2) (2014) 315 ALR 1 at 2 [2]:
The disposition of costs is within the general discretion of the court. Ordinarily, that discretion will be exercised so that costs are awarded to the successful party, but other factors may have a significant claim on the discretion of the Court [Stewart v Atco Controls Pty Ltd (In liq) (No 2)(2014) 252 CLR 331 at 334 [4]]. The disposition which is ultimately to be made in any case where there are competing considerations will reflect a broad evaluative judgment of what justice requires.
7 The relevant principles were summarised by the Full Court in EMI Songs Australia Pty Limited v Larrikin Music Publishing Pty Ltd [2011] FCAFC 92 ("EMI") as follows at [9]:
Costs are in the discretion of the Court (Federal Court of Australia Act 1976 (Cth) s 43). The discretion is broad but is to be exercised judicially. The fundamental purpose of the discretion is to compensate the successful party, not to punish the unsuccessful party. The furtherance of the goal of compensation means that, in general, a successful party will obtain an order for costs in its favour (Oshlack v Richmond River Council (1998) 193 CLR 72; [1998] HCA 11 at [65]-[68]). However, "a successful party who has failed on certain issues may not only be deprived of the costs of those issues but may be ordered as well to pay the other party's costs of them…" (Hughes v Western Australian Cricket Association (Inc) (1986) ATPR 40-748 at 48,136). If apportionment of costs is appropriate, the object is not mathematical precision (Dodds Family Investments Pty Ltd (formerly Solar Tint Pty Ltd) v Lane Industries Pty Ltd (1993) 26 IPR 261 at 272) but a result that best reflects the interests of justice in the overall circumstances of the case.
8 It is well recognised that "[a] successful party who has failed on certain issues may not only be deprived of the costs of those issues but may be ordered as well to pay the other parties' costs of them. In this sense 'issue' does not mean a precise issue in the technical pleading sense but any disputed question of fact or law": Ruddock v Vadarlis (No 2) (2001) 115 FCR 229 at 234 [11] per Black CJ and French J.
9 Thus, while the ordinary rule is that costs follow the event, the Court exercises a broad discretion with respect to costs that permits it to adopt other approaches, which may be more appropriate in litigation involving a multiplicity of parties, issues or outcomes.
10 Section 43(3)(c) of the FCA Act makes clear that the Court may, in its discretion, order the parties to bear costs in specified proportions. Orders in that form are often made with a view to avoiding an overly complicated taxation of costs which may give rise to further costs that may be unnecessary or disproportionate to the amount in issue in the proceeding. As the Full Court made clear in EMI, the object of such an order is not to apportion costs with mathematical precision but to arrive at an outcome that best reflects the interests of justice. In determining what proportion of one party's costs another party should bear, it will usually be necessary for the Court to make a broad assessment of the time and effort spent by the parties litigating different issues.
11 The question of costs in this matter is complicated by the fact that there were five sets of proceedings heard together brought by the applicant in which the applicant was represented by the same counsel and solicitors and the respondents were represented by two different groups of counsel and solicitors. In that regard, I have derived some assistance from the judgment of Goldberg J in Dr Martens Australia Pty Ltd v Figgins Holdings Pty Ltd (No 2) [2000] FCA 602. That was a case in which the applicant brought four separate proceedings which were heard together. The applicant was wholly unsuccessful against the respondents in three of those proceedings but enjoyed some limited success against certain respondents in the fourth. His Honour observed at [3]:
The four proceedings were heard together so that evidence of the applicants was not duplicated and the respondents in each proceeding in a number of respects relied on the evidence of the respondents in the other proceedings. The result was that a substantial body of evidence led by the applicants was only led once although it was subject to cross-examination by each set of respondents. There were costs consequences in two respects. First there was a saving of time and costs for the applicants who only had to lead their evidence once with a consequent saving of time and expense not only with evidence-in-chief but also in relation to cross-examination as, substantially, cross-examination was not duplicated. Secondly, each group of respondents effectively had to participate in the whole of the trial which meant that they were present whilst other respondents were conducting their cases with a consequent increase in expense. Overall there was a substantial saving of Court time.
12 As I explained in the principal judgment, the applicant was represented by Mr Green SC with Ms Oliak, Dr O'Shea and Mr Cameron, all of whom were instructed by the firm of LJ Sharpe & Co. The respondents in the Bush Pharmacy, Down Under and New Directions proceedings were represented by Mr Fox and Mr Hallahan, both of whom who were instructed by Gadens Lawyers. The respondents in the Native Oils proceeding and the Heritage Oils/Levinson proceeding were represented by Mr Reuben and Ms Whitaker who were instructed by Malcolm McDonald & Co Solicitors.
13 What Goldberg J said in Dr Martens at [3] holds true in the present case. The fact that the five proceedings were heard together gave rise to some savings in time and costs because the patent validity issues and at least some of the patent infringement issues (primarily the s 117(2)(b) issues) were able to be dealt with without the duplication of time and effort that would have likely occurred if the proceedings had not been heard together. Some savings were no doubt also achieved because all of the respondents were represented by either Mr Fox and Mr Hallahan or Mr Reuben and Ms Whitaker. On the other hand, each respondent had to participate in the whole of the trial and sit through some lengthy cross-examination, argument and submissions relevant to the applicant's case against other respondents, including other respondents against whom the applicant has obtained no relief.
14 I was informed by Mr Fox that the respondents in the Bush Pharmacy, Down Under and New Directions proceedings had entered into costs arrangements under which the costs of their representation by counsel and solicitors were to be equally shared between Bush Pharmacy, Down Under and New Directions.
15 In the Native Oils and the Heritage Oils/Levinson proceedings I was informed by Mr Reuben that Native Oils and Heritage Oils have also agreed to share the respondents' costs of those two proceedings. In particular, I was informed that the respondents in the Native Oils proceeding are responsible for 50% of the costs incurred in relation to their legal representation and that Heritage Oils and Ms Levinson are jointly responsible for the remaining 50% of those costs.
16 I mention these costs sharing arrangements because they are relevant to the manner in which I propose to exercise my discretion in relation to costs. The costs orders I propose to make will be made on the basis that what I have been told by the respondents' respective legal representatives in relation to the costs sharing arrangements made between their clients is correct.
17 It is useful to refer to the different outcomes that were reached in the five proceedings:
(a) In the New Directions proceeding and the Native Oils proceeding, the applicant was wholly unsuccessful in establishing any of the pleaded causes of action upon which it relied. In the result, the proceeding brought by the applicant against New Directions and the proceeding brought by him against Native Oils will be dismissed. Each of those parties is entitled to its costs of the application filed by the applicant.
(b) In the Bush Pharmacy proceeding, the applicant established that Bush Pharmacy had infringed claim 5 of the patent by supplying, or offering to supply, Kunzea ambigua oil in circumstances referred to in s 117(1) when read with s 117(2)(c) of the Act. Bush Pharmacy was also found to have contravened s 18 and s 29(1)(a) of the Australian Consumer Law ("ACL").
(c) In the Down Under proceeding, the applicant established that Down Under had contravened s 18 and s 29(1)(a) of the ACL, but failed to establish that Down Under had infringed the patent .
(d) In the Heritage Oils/Ms Levinson proceeding, the applicant established that Heritage Oils and Ms Levinson had infringed claim 5 of the patent, but failed to establish the alleged contraventions of s 18 and s 29 of the ACL.
18 Each of the respondents applied for orders revoking the claims of the patent upon which they were sued. Ultimately, the applicant accepted that claims 1-4 (each of which is a product claim) were invalid for lack of novelty. That concession was not made until day five of the trial. The other claims challenged by the respondents were all method of treatment claims. Some of these were found to lack clarity based on the existence of the obvious errors that will be corrected by the orders to be made pursuant to s 105(1) of the Act. However, each of the respondents found to have infringed the patent, was found to have infringed claim 5, the validity of which did not depend upon the making of any order under s 105(1).
19 The respondents asserted that the claims upon which they were sued were invalid on a number of different grounds including that the invention claimed was not for a manner of manufacture and did not involve an inventive step. The challenge to the validity of those claims failed in so far as it was based on lack of inventive step. Because the applicant ultimately accepted that claims 1-4 were invalid for lack of novelty, it was not necessary for me to decide the issue of manner of manufacture in relation to those claims.
20 The respondents also challenged the validity of claims 8 and 9 on the basis that each claim lacked fair basis. That challenge was successful in relation to claim 8. The challenge made in relation to claim 9 failed. The fair basis issues did not, in my view, add significantly to the evidence or the time spent on submissions.
21 The applicant submitted that the fact that he was successful in establishing infringement of claim 5 in the Bush Pharmacy and the Heritage Oils/Levinson proceedings, should weigh against those parties' entitlement to any costs in respect of their challenge to the validity of the patent. In effect, what the applicant submitted was that, at least in those proceedings, the applicant should have all its costs of defending the cross-claims because it was successful in establishing infringement of claim 5 of the patent.
22 The applicant also submitted that a great deal of attention was given in both the evidence and the parties' submissions to validity issues upon which the respondents failed. He referred, in particular, to the extensive expert evidence that was filed directed to the issue of inventive step. This included most of the evidence of Dr Carson, Dr Clark, Dr Southwell, Professor Menary and Dr Narkowicz. However, as is apparent from the principal judgment, Dr Narkowicz's evidence was mostly concerned with the question whether Kunzea ambigua oil was a staple commercial product. In my view his evidence had very little bearing on the issue of inventive step. Subject to that qualification, I accept that most of those witnesses' evidence was primarily concerned with the issue of inventive step.
23 The applicant, while succeeding under claim 5 against some respondents, wholly failed in his action based on claims 1-4. These were the product claims which, had their validity been upheld, would have enabled the applicant to recover damages from each of the respondents for what would have been a direct infringement of the patent. The significance of the applicant's belated concession that claims 1-4 were invalid for lack of novelty is not to be underestimated. In particular, I do not accept the applicant's submission that, because the applicant succeeded against some of the respondents under claim 5, then he should be awarded all of his costs in relation to the patent case. That submission ignores the significant difference between a product claim and a method of treatment claim and the much broader scope of protection usually provided by a valid product claim.
24 Most of the expert evidence filed by both parties was filed in the New Directions proceeding but when read, became evidence in all five proceedings. I was not provided with any information by the respondents as to the arrangements in place in relation to the costs of producing the expert evidence which, I assume, was covered by the costs sharing arrangement between Bush Pharmacy, Down Under and New Directions to which I have previously referred.
25 Although Mr Fox undertook most of the cross-examination in relation to the validity issues and made almost all of the submissions on the question of validity, the other respondents represented by Mr Reuben adopted the submissions made by Mr Fox on the validity issues. All respondents relied on the same validity arguments as those developed by Mr Fox on behalf of Bush Pharmacy and the other respondents for whom he appeared. In substance, there was a single cross-claim supported by the same body of expert evidence and the same submissions. That is an important consideration in determining what approach to take in relation to the costs of the cross-claims filed in the five proceedings.
26 The respondents sought indemnity costs in relation to the claim for additional damages for patent infringement. I refer to the way in which this claim had been pleaded in the principal judgment and the absence of any evidence which could support findings of additional damages based on the matters that were pleaded.
27 All the respondents against whom the applicant made a claim of trade mark infringement also sought costs orders that would permit them to recover their costs of the trade mark infringement case on an indemnity basis.
28 I turn now to consider what costs orders should be made in each of the five proceedings. However, before continuing I should refer in more detail to the offers of compromise that were made by three of the respondents.
