Consideration
21 We are conscious of the fact that the primary judge's refusal to permit Hytera to plead the proposed amendments involves a discretionary judgment on a matter of practice and procedure. We acknowledge that an appeal court should exercise cautious restraint before interfering with such a judgment. Having said that, we also accept that substantial injustice would result to Hytera if his Honour's decision were to remain, assuming it to be attended by sufficient doubt. Hytera can only ventilate its proposed claims in the context of the primary proceeding.
22 It is trite that, generally speaking, an appellate court will only interfere with a discretionary judgment if the exercise of the discretion miscarried in some material way - such as, for example, the primary judge acting on a wrong principle, allowing irrelevant matters to affect the decision, mistaking the facts or failing to take account of some material consideration. In the present case, we are persuaded that his Honour's discretion miscarried in material ways.
23 First, we are persuaded that his Honour erred in finding that the proposed amendments lacked coherence.
24 In this connection, we accept Hytera's submission that, in reaching this finding, his Honour appears to have proceeded on the basis that Hytera's allegations of delay were only engaged after an anterior finding of flagrant conduct. However, the proposed amendments include allegations that are directed to disputing the very proposition that Hytera did, in fact, act flagrantly, assuming infringement to be established.
25 Further, even if the Court were to find, on final analysis, that Hytera acted flagrantly, Hytera wishes to add facts (in respect of which it will bear the onus of proof) which qualify the nature of its conduct. In this connection, Motorola's allegations of flagrancy are made in the context of a claim for additional damages. As the relevant provisions in the Patents Act and the Copyright Act make clear, in considering whether additional damages should be awarded, the Court is required to consider factors extending beyond the fact of flagrancy. In short, flagrancy, as such, is not the only relevant consideration in an award of additional damages. These other factors include the conduct of the infringer after the acts of infringement (including after the infringer has been informed that it has infringed the rights in question), and the benefits accruing to the infringer by reason of the infringements that are found. Indeed, the factors that are required to be taken into account extend to "all other relevant matters" - meaning, all other matters that can be seen, rationally, to bear on an assessment of the conduct that is found to be infringing and the context in which that conduct takes place. The delay which Hytera alleges, and the alleged consequences on which it seeks to rely, can be seen to fit within the purview of the relevant provisions, even if the Court should find, by reference to other facts, that Hytera has acted flagrantly (once again, assuming infringement to be established). Thus, the primary judge's approach does not reflect the full scope and operation of the provisions in question.
26 Further, the amendments which Hytera proposes are also directed to other aspects of the relief that Motorola seeks, independently of the question of additional damages and any finding that Hytera acted flagrantly. Specifically, these amendments are directed to aspects of Motorola's conduct (not Hytera's conduct) on which, if established, Hytera would seek to rely to contend that Motorola is disentitled to all or part of that other relief: see [17] above. It is not apparent that the primary judge took these considerations into account when considering whether Hytera should be granted leave to amend.
27 In referring to these matters, we should not be taken as expressing any view on the strength of the case that Hytera wishes to advance in respect of Motorola's alleged delay. The only question is whether Hytera should be afforded the opportunity to raise the question of that delay. For present purposes, we accept that the delay, if established, may be relevant to determining whether Hytera's conduct was flagrant and, if flagrant, relevant to viewing that conduct in a context which reveals, more finely, its true character. More broadly, it may be relevant to the question whether, in light of all relevant matters, an award of additional damages is appropriate. We also accept that relevant delay, if established, could affect Motorola's entitlement to the other relief it seeks.
28 Secondly, with respect to Hytera's delay in raising the proposed amendments, we note that the primary judge considered delay from the standpoint of the patent infringement claims which had been on foot for some time. His Honour did not refer to, and does not appear to have considered, the relatively recent introduction by Motorola of its copyright claims and its allegation that, in that context, Hytera acted flagrantly. Pleadings on that claim did not close until April 2019.
29 The allegations of flagrancy in the copyright infringement case are based on the same underlying facts as the allegations of flagrancy in the patent infringement case - primarily, the conduct of the Hytera Personnel. If it be the case, as the primary judge found, that Hytera could have raised, long ago, Motorola's alleged delay in raising the issue of flagrancy in the context of the additional damages claim in the patent infringement case (a matter to which we will return), then that was not the position with respect to the corresponding claim in the recently introduced copyright infringement case. Indeed, his Honour made no finding that Hytera had delayed in raising the proposed amendments in that context.
30 Thus, delay could not stand as a reason for refusing the proposed amendments to the extent that they bear on the copyright infringement case. But if that be so, there appears to be no cogent basis for not permitting Hytera to also raise Motorola's alleged delay in answer to the claim for additional damages for patent infringement. This is because, fundamentally, the same facts are at issue, namely whether, by reason of the matters it knew in late 2010/early 2011 and thereafter, Motorola delayed in informing Hytera of the allegation that Hytera had infringed Motorola's intellectual property rights as part of a course of conduct involving knowing and intentional copying and misuse of information and documentation relating to Motorola's digital mobile radio devices.
31 With respect, we think that the assessment of any delay by Hytera in raising the proposed amendments could not ignore this consideration. In short, we are persuaded that the primary judge erred in considering Hytera's delay only from the standpoint of the patent infringement case. By considering Hytera's delay in raising the proposed amendments only from the standpoint of the patent infringement case, the primary judge precluded Hytera from raising Motorola's alleged delay as reason for refusing all or part of the other relief that Motorola seeks for copyright infringement.
32 As we have noted, the primary judge found that Hytera's explanation for its delay in raising the proposed amendments was unsatisfactory, essentially because his Honour reasoned that Hytera should have applied in the US proceeding to permit the issues raised in that proceeding, which, as explained above, had been covered by a protective order, to be communicated to Hytera's Australian lawyers. However, Motorola did not raise that circumstance in the course of the amendment application as relevant to his Honour's consideration of Hytera's delay. Further, the protective order prevented Hytera's US lawyers from disclosing matters, including the factual basis for the delay allegations, to Hytera or its Australian lawyers. As Hytera puts it, Hytera (either directly or via a request from Hytera's Australian lawyers) could not be expected to have instructed, in the abstract, the US lawyers to apply for a release of the protective orders in respect of information to which Hytera was not privy.
33 We return to the question of whether there has been delay on Hytera's part in proposing the amendments. Mr Vincent is a principal of the lawyers who have been retained by Hytera to conduct its defence of the copyright infringement claims and in relation to the allegations concerning Motorola's entitlement to additional damages, including in respect of the allegations of copying and misuse of information and documents. Mr Vincent made a number of affidavits which were relied on in support of Hytera's amendment application. Mr Vincent deposed to his view, which does not seem to have been challenged, that, although certain inferences in respect of delay by Motorola were open to be made, he did not consider that Hytera had sufficient facts to support a pleading in respect of that delay before reading the decision of the US Court. Hytera's Australian lawyers were aware that there was a decision in mid-March 2019, but were not able to review and assess it until obtaining a copy on 2 April 2019. Mr Vincent read the decision on 4 April 2019. Before that time, it had been Hytera's intention to obtain further information in order to plead delay. Motorola had refused to provide discovery on that topic. That refusal was overtaken by the availability of the US decision, which now provides Hytera with information which it considers to be sufficient to properly allege delay on Motorola's part. As we have stated, this evidence does not seem to have been challenged and provides a substantial reason for not raising the proposed amendments earlier.
34 At [7] of his reasons, the primary judge referred to the fact that, had the allegations of Motorola's alleged delay been raised earlier, it is likely that Motorola would have been entitled to discovery in relation to Hytera's contentions about its ignorance of the conduct of the Hytera Personnel. We do not presume to intrude on his Honour's management of the proceeding in this respect. However, we do wish to record what seems to be Hytera's acceptance that there is no reason why Motorola cannot seek appropriate discovery from Hytera on this topic at a time before May 2020, when the question of Motorola's entitlement to additional damages is listed for hearing.
35 We also wish to record that, under current case management orders, Hytera is required to file its evidence in answer to the copyright claim and on the question of additional damages in the coming month. Hytera informed the Court that it anticipates that this evidence will address the steps that Hytera would have taken had Motorola not (allegedly) delayed in notifying Hytera of its allegations of knowing and intentional copying and misuse of information and documentation relating to Motorola's digital mobile radio devices. Motorola's responsive evidence is to be filed in March 2020.
36 For these reasons, we will grant leave to appeal and allow the appeal, with the intent that Hytera will have leave to file the third further amended defence, the draft of which was before us.
