The respondents' position on implementation of the claimed system
17 Voxson insisted that Optus had, itself, implemented assisted GPS (A-GPS). This was maintained through a number of hearing days and four different versions of the statement of claim, until the proposed amended pleading served on 23 March 2015 (the proposed March pleading). Optus submits that this amounted to the making of groundless contentions and allegations and a refusal, by a party holding a patent in the field of telecommunications and therefore with a degree of expertise, to investigate necessary matters of fact upon which the cause of action was said to be founded.
18 Optus says that Voxson failed to investigate matters that could readily have been ascertained (as in Australian Guarantee Corporation Ltd v De Jager [1984] VR 483 where Tadgell J awarded indemnity costs for a "high-handed presumption") and where the proceedings have been "grossly prolonged", thereby subjecting Optus to costs 'far beyond what [it] would really have expected to incur in litigation of the genuine issues'. Optus emphasises that the onus was not on it, as a respondent, to prove to Voxson's satisfaction that it did not implement the claimed system before Voxson would amend its pleaded causes of action.
19 I have read and taken into account the many letters in evidence that passed between the parties but shall refer only to some of them, as necessary.
20 Optus points to its letter of 22 September 2014 (the September letter), preceding the filing of the strike out application, where it:
asserted an absence of a factual foundation for the case of infringement;
stated that Optus has not implemented the infrastructure and protocols to support A-GPS in its network, either on the control plane or the user plane;
dealt with each step of the claimed allegations and asserted that there was no implementation;
pointed out that the Vox 1 pleading was premised on the Optus infrastructure implementing the steps, including use of Secure User Plane (SUPL) architecture, and asserted that Optus has not implemented any such system; and
pointed out that the examples provided in the pleading refer to the SUPL enabled mobile device or terminal's (SET) use of A-GPS and not to implementation by the Optus network, but rather that the particulars indicated a third party provision of the A-GPS services.
21 Voxson's response was to say that Optus did not dispute that it sold and authorised 'activities, services and products' which had A-GPS capability. Voxson then asked for an explanation of Optus' denial, without saying what was incomplete in the detailed denial set out in the September letter. Further, while SUPL was included in the case being made by Voxson at that time, its reply made it clear that its allegations, including those as to SUPL, were in the context of services operated by or on behalf of Optus and its related bodies corporate, as set out in amended statement of claim filed on 29 August 2014 (the pleading).
22 In the September letter, Optus not only complained of the lack of particulars in the pleading, it also set out its understanding of the case being made against it, being that it had implemented an A-GPS system. It went further, as it provided a summary of the steps alleged in that statement of claim and asked for confirmation that the summary was accurate or, if not, why not. It pointed out that the steps in the pleading were 'premised upon the Optus Infrastructure' receiving requests and responding. It then stated: 'We are instructed that in fact this does not occur, because Optus has not implemented any such system'.
23 In the September letter Optus referred to the Nokia N95, as particularised in the pleading, and stated:
Particulars (e) and (f) to [146] refer to the iPhone and the Nokia N95 as offering A-GPS features. That does not indicate that Optus infrastructure provides or has implemented such a service. Indeed, the particularised Nokia manual indicates that Nokia provided the A-GPS service in the absence of the configured service. We assume that your client does not assert that these matters suggest that Optus has implemented on A-GPS system.
24 The response from Voxson was a reiteration that the allegations concerned 2G, 3G and 4G location servers and SUPL Location Platforms operated by or on behalf of the Optus respondents.
25 Voxson complains that it did not and does not understand what Optus meant by using the word "implemented". That complaint must be rejected. Even to the lay reader, let alone to a reader of the relevant sophistication of Voxson as the patentee, the meaning is abundantly clear. In any event, when Voxson responded on 10 October 2014, it did not complain about the use of the word but asked for the basis of the denial and whether the denial extended to a capability of using the claimed system. Voxson maintained that the servers involved in its allegations were those operated by or on behalf of Optus. There was no suggestion by Voxson of a third party server.
26 After the first day of the hearing of the strike out application on 4 February 2015, when Optus' counsel had made statements to the effect of the contents of the September letter and Voxson had said that it may wish to investigate third party implementation, Optus again wrote to Voxson. It repeated part of the September letter and reiterated that A-GPS had not been implemented in the Optus network, whether by Optus or by a third party on its behalf. It reminded Voxson that it had stated back on 3 May 2012, by letter, that it does not provide an A-GPS service.
27 Voxson said that this assertion conflicted with Dr Harper's evidence.
28 As at 5 February 2015, Optus' stated position was that Dr Harper's evidence did not involve testing what the network does and that the Optus infrastructure (Optus 2G-GERAN and/or external servers operated by or on behalf of Optus) may be used 'simply as a conduit, as dumb pipes', as in the transmission of emails. Dr Harper's evidence was to the effect that the Optus network was 'in some way' providing assistance data. On that same hearing day, counsel for Telstra stated that Telstra does not implement A-GPS with respect to the 4G network and added: 'frankly, we think that those in the industry must know that no telecommunication provider would because with this latest level of technology, your Honour, handset makers are implementing their own A-GPS arrangements'. Vodafone placed itself in the Optus camp, stating that Vodafone does not believe that it implemented A-GPS and adopted 'the dumb pipes theory'.
29 Despite this appearing on the transcript, Optus again wrote to Voxson on 5 February 2015. It stated that the pleading required:
for all forms of infringement, that the Optus Infrastructure (ie 2G GERAN and any external location servers operated by or on behalf of Optus) must respond to a request from the Location Based Services application by transmitting the pleaded RRLP (or RRC, LPP or UPL) messages, as specified in the Standards, to a mobile device; and that it must also respond to information received back from the mobile device by undertaking the further processing of that information pleaded in relation to each mode. This may be referred to as the implementation of A-GPS in the Optus Network.
(emphasis added)
30 There could not have been any misunderstanding at all of what Optus meant by "implementation". Optus also explained in the letter the detail of the alternative mechanism which does not involve the implementation of A-GPS in the Optus network, using the Optus network "pipes" as a conduit, an 'over the top service', and points out that the statement of claim 'does not and could not allege that Optus is liable for such scenarios', pointing out that Voxson's oral submissions confirmed that the over the top scenario is not what is embraced by "external location servers" of the then current statement of claim, the pleading. It pointed out that Dr Harper's affidavit did not distinguish between the two possibilities, or distinguish between the implementation of A-GPS in the Optus network and an over the top application.
31 Vodafone also wrote to Voxson on 5 February 2015. In that letter, Vodafone stated that it does not accept the position put forward by Voxson's senior counsel that Vodafone accepts that it provides A-GPS. Vodafone stated that it 'made it clear in its letter of 26 September 2014 that it does not implement the system as claimed in the Vox 1 GPS Patent'. In its letter dated 26 September 2014, Vodafone stated the following:
We are instructed that Vodafone does not implement any system as claimed in claims 1-4, 10-15, 22 and 24 of the Vox 1 GPS Patent. In particular, Vodafone does not employ a system in which there is a process of 'correcting' existing data as described in paragraphs 72-74 of the FASOC.
32 On 4 February 2015, the solicitor for Vodafone stated that Vodafone 'didn't say we didn't do Assisted GPS, we just said we did not implement the system of claim 1.' However, on 5 February 2015, the solicitor for Vodafone informed the Court that he was now instructed that 'Vodafone does not believe that it implemented Assisted [GPS]' and offered to write formally to Voxson to inform them of that fact, resulting in the letter of 5 February 2015.
33 Voxson's response to all respondents on 9 February 2015 was to demand 'an Affidavit supported by documents which demonstrate each of your clients' respective positions' and ask a series of specific questions. On 9 February 2015, Optus filed the affidavit of Mr Colgan dealing with the lack of implementation and the function of the network only as a conduit, without knowledge or control of the data. A concurrent affidavit of Mr Hayes reported on experimental use and raised the possibility of receipt of data from an external source, that is, a third party server through the conduit of the Optus mobile data connection. Mr Hayes, in his affidavit dated 23 February 2015, subsequently identified the relevant registrant of the URL, which was not Optus.
34 Dr Harper stated that the Optus Nokia device 'received A-GPS information by use of a SUPL server and the Optus 3G Network'. On 19 June 2015, Mr Colgan stated in a further affidavit that:
In relation to the function of the Optus network as a conduit for a third party SUPL service, such a service, in order to operate, may utilise a cellular mobile network (such as a 2G, 3G or 4G network) as a conduit, but it does not require the cellular mobile network to have any functionality other than its pre-existing functionality as a 2G/3G/4G network. Optus has not implemented in its mobile telecommunications network (that is, incorporated any functionality other than its pre-existing functionality as a 2G/3G/4G network) any of the OMA Secure User Plane Location standards.
35 Optus' position was that it did not implement the claimed system and that there is a difference between it providing A-GPS and third party A-GPS which interoperates with the Optus infrastructure. That position was reiterated in writing and orally during the early days of the hearing of the strike-out application. It was made clear, despite Voxson's assertions that Optus did not clarify whether there was an infringing system being operated on its behalf, that Optus did clarify that as early as 22 September 2014, in the September letter. It was clearly stated that the denial of implementation extended to an 'external service as operated by or on behalf of Optus'.
36 This, Optus says, represented a clear statement that equated to an explanation that the Optus network functions as the "dumb pipes" for the purposes of transmission of messages. While the expression "dumb pipes" was not used in the correspondence relied on by Optus, it is a reference to a third party service providing the A-GPS data using the Optus network as a conduit. This, Optus emphasises, was precisely what it stated in the September letter, including identifying Nokia as a relevant third party. Even if there was an onus on Optus to inform Voxson of the "dumb pipes" position, which it refutes, it points out that it did so. It did so again in its opening written submissions dated 25 January 2015 and again during the hearing on 5 February 2015.
37 When Voxson, on the second day of the February 2015 hearing, adduced evidence from Dr Harper, for the first time purporting to establish that Optus had implemented A-GPS by a demonstration with a Nokia phone as sold by Optus, Optus immediately pointed out that the evidence only supported the conclusion that a third-party service was providing assistance data, utilising the Optus network as a conduit only. Optus' explanation about this was detailed. Optus adduced evidence from publicly available sources to support its contentions and the explanation.
38 Voxson's response was not to amend its pleading but to tell the Court that it was to seek further information from Optus and, on the third hearing day, 10 February 2015, Voxson indicated that it would state its position on the Vox 1 proceedings as quickly as possible. In fact, Voxson did not respond to Optus' letters dated 10 and 13 February 2015, the latter seeking urgent clarification as to whether Voxson intended to pursue this proceeding against any of the Optus respondents, and set out its position prior to the matter returning to Court for the fourth hearing day. Voxson still maintained that Optus implemented A-GPS, relying on the evidence adduced from Dr Harper.
39 That same evidence from Dr Harper was, by 25 August 2015, relied upon by Voxson to establish that Nokia, a third party, and not Optus, provided the A-GPS service, that is a third party SUPL server. Optus adds this to the matters that had to be clarified by successive hearings as Voxson changed its reliance on Dr Harper's evidence from supporting implementation by Optus to supporting the identification of the third party server SUPLNokia.com.
40 Voxson did not seek to investigate its contention that the Optus mobile network had implemented A-GPS, notwithstanding Optus' denial prior to the commencement of proceedings that it had done so. Voxson's pleadings and correspondence have never, at any subsequent stage, provided any substantiation for that contention, notwithstanding the reiteration of that denial and the requests for information made by Optus in correspondence, in Optus' interlocutory application and in its submissions in support of that application. Eventually, on the first day of the hearing, after Optus' senior counsel explained Optus' position again, Voxson offered to consider its position against Optus. However, having done so it then, on the following day, sought to adduce evidence of an experiment it had just conducted which, it said, indicated that Optus had implemented A-GPS. Optus immediately pointed out, including by reference to Voxson's own particularised documents, that this experiment indicated that the device was using a third party service, not any service implemented by the Optus mobile network. Voxson provided no substantive response to this.
41 All of the above is relied upon by Optus to support its submission that the pleading was unsupported by material facts and should never have been pleaded and that this was due to Voxson's failure to investigate available facts, having ignored Optus' assertions and its own evidence, until it abandoned the original assertions in the proposed March pleading and substituted the pleading based on SUPL, being the third party A-GPS case.
42 The following short chronology of the Vox 1 proceeding, with respect to Optus, is relevant in the context of the above:
Voxson, in correspondence commencing in 2007, alleged that Optus implemented A-GPS.
After other correspondence, on 3 May 2012, Optus stated that it did not provide an A-GPS service.
Voxson commenced proceedings on 29 November 2013 but Optus was not served with this statement of claim.
Optus was served with an amended statement of claim on 12 June 2014.
On 19 September 2014, a further amended statement of claim was served (filed on 29 August 2014).
On 22 September 2014, Optus wrote the September letter.
On 24 October 2014, Optus filed its interlocutory strike out application.
The first round of hearing of the interlocutory application commenced on 4 February 2015. Voxson states that it was only during this hearing that Optus raised the "dumb pipes" or third party service theory. Voxson makes no reference to the continued denial by Optus in correspondence of implementation of A-GPS in its network or its repeated references, from the September letter, to the alternative scenario, not pleaded, of a third party service.
On 10 February 2015, at the resumed strike out hearing, Voxson indicated that it would state its position as quickly as possible.
Voxson still refused to abandon the pleading that Optus, or someone on its behalf, implemented A-GPS at the resumed hearing on 25 February 2015.
43 Optus did not hide its position - it openly and clearly stated it.
44 In the circumstances set out above, it was unreasonable for Voxson to have commenced and maintained the pleading against Optus and to have subjected Optus to the consequential costs of maintaining its position.
45 Turning to a matter arising from the proposed March pleading, Optus points out that it notified Voxson of a problem it identified in the proposed March pleading as to the signalling layer/traffic channel of the claimed system on 17 April 2015, in a written submission. This asserted problem did not arise until the amendments to the pleading that gave rise to the proposed March pleading, which were the subject of the hearing in August 2015 (being version 2 of the second further amended statement of claim). Optus submits, correctly, that although Voxson subsequently made a further proposed amendment to include both the traffic and control channels as constituting the "special signalling layer", it was forced to argue the point in August 2015, despite having clearly warned Voxson of the problem it identified.
46 Optus also points out that it has had to deal with 'a litany of changed positions'. Optus submits that it should never have been obliged to pay the costs of the arguments, in particular where Optus had pointed out in writing the problems with Voxson's case and where Voxson first refused to change its position and then, when argued by Optus at a hearing, Voxson re-pleaded such that Optus had to look at the next version afresh and, again, point out "flaws" which were then dealt with in the same way. Optus points out that it was not until the proposed March pleading that Voxson abandoned allegations of implementation, without explanation as to why this was not done earlier. Optus relies on the observation by Heerey J in Black & Decker Inc v GMCA Pty Ltd (No 3) [2008] FCA 932 at [35] that while '[s]ome latitude needs to be allowed for the changing of a party's case as investigations reveal possible new arguments… a line has to be drawn somewhere'.
47 Optus' description is not an unfair description of what has occurred.
48 Reciting the relevant authorities, such as De Jager and Black & Decker, Optus' case for indemnity costs is to rely on:
The making of groundless contentions or allegations that the Optus network had implemented A-GPS with no factual foundation.
The refusal to investigate critical matters of fact upon which the action was said to be founded and yet maintaining the proceedings. Voxson did this despite Optus' denials prior to the commencement of proceedings and continued denials subsequently. Further, Voxson did this despite the fact that the evidence on which Voxson sought to rely to establish that Optus had implemented the system, that of Dr Harper, was pointed out by Optus to indicate a third party server.
The unreasonableness of subjecting Optus, as the innocent party, to expenditure of costs.
