Subsequent changes to the pleading
42 The pleading underwent a number of iterations before the proposed amended pleading. A comparison is not straightforward. However, one relevant amendment was to change the assertion that the external location servers were operated by Optus or on its behalf to an assertion that the servers were operated by Optus or entities other than Optus. A key amendment was that Voxson no longer claimed that Optus implemented A-GPS, rather it claimed that Optus is liable for an A-GPS service implemented by third parties on third party servers.
43 It is fair to say that there were wholesale amendments made, which in part reflected a different case being made as to the nature of the system alleged to have been implemented and the involvement of the Optus network.
44 In a position paper served with the statement of claim relied upon as at 23 March 2015 (the proposed March pleading), Voxson stated that it no longer alleged direct or secondary infringement in respect of the Optus 2G Network, 3G Network or 4G Network. Voxson no longer alleged direct infringement in respect of Optus SUPL but continued to allege secondary infringement in respect of Optus SUPL.
45 By proposed amendment, the previous definitions of Optus 2G/3G/4G SLP were no longer used. SLP was now defined to denote one or more SUPL Location Platforms that transmit Satellite Data while working with the Optus 2G GERAN, 3G UTRAN and 4G E-UTRAN. It was no longer alleged that Optus operated, or had operated on its behalf, the SLP. Voxson's position was that, in the context of secondary infringement, it was the consumer who uses the claimed system, which includes the SLPs. Voxson maintained the allegation that Optus operated its 2G/3G/4G Networks and the respective 2G GERAN/3G UTRAN/4G UTRAN during the infringement period, but no changes limited that to a claim of direct infringement.
46 The pleading was further amended in the proposed March pleading so that the particulars did not differentiate between whether the system is a product, method or process, but related to Optus' acts of exploitation. The allegation was that Optus authorised the use by the consumer of the claimed system. The provision of Location Based Services as alleged in the pleading was amended to refer to the provision of Location Based Services applications in the proposed March pleading.
47 Voxson explained this as amendments being made to remove any paragraphs of the pleading that were 'no longer necessary' with paragraphs being retained that related to allegations of infringement concerning Optus SUPL.
48 Optus submitted that the change in the case, from actual implementation of A-GPS in the pleading to liability for an A-GPS service implemented by third parties on third party servers in the proposed March pleading was 'fundamentally different in character from the case previously pleaded'. I accept Optus' characterisation. Although authorisation was originally pleaded and had been maintained, and SUPL was referred to, taking the pleadings as a whole, Optus' submission should be accepted.
49 Optus then raised concerns as to the proposed March pleading, including:
As to asserted compliance with the SUPL Standards, it is not mandatory for either a network operator or a third party location service provider to implement the SUPL Standards. The proposed March pleading did not assert that it is.
The Optus mobile network has not implemented the SUPL Standard.
The proposed March pleading did not identify any basis for asserting that Optus or a relevant third party service provider or server has implemented the SUPL Standards.
The proposed March pleading conceded that any third party service provided utilised the data channel (or "traffic" channel) of the Optus network. The consequence is that the requirement of all pleaded claims for the relevant signal to be transmitted on a "special signalling layer" was, on the face of the pleading, unfulfilled.
The conduct pleaded cannot amount to authorisation.
50 Optus adduced evidence, that was unchallenged, that it has not provided or implemented an A-GPS service on its mobile telecommunications network, and neither has a third party on its behalf. This includes a SUPL service. The Optus mobile telecommunications network does not incorporate a SLP and Optus does not operate any such platform. The Optus network functions only as a conduit of the relevant data between the handset and the third party infrastructure. The network does not distinguish such data from other data such as email data. Optus has no knowledge of, or control over, communications of such data. Optus has not implemented in its network any of the SUPL Standards.
51 Voxson raised certain matters as to that evidence, such as a distinction between assertions couched in the present tense and those in the past tense and as to the asserted incapability to manage data sent on the network - an asserted distinction for example between "cannot" distinguish data and "do not" distinguish data. This does not detract from the general assertions by Optus. Voxson did not suggest that it has any evidence to contradict Optus' evidence.
52 In written submissions elaborating this position, Optus drew attention to the fact that, in the pleading, Voxson did not plead any case involving a SUPL service implemented by a third party but pleaded a requirement for the Optus mobile network to have implemented an A-GPS service. Optus' secondary liability was pleaded as derived from consumers' alleged use of the system that was said to have been implemented by Optus. Accordingly, while it is correct that, as Voxson asserts, Voxson continued to allege secondary infringement in respect of Optus SUPL, it was a different case being alleged.
53 Optus again raised issues about the identity of the location server, the third party service provider, and whether the SLP is situated in Australia. If the SLP is not operated in Australia then, Optus said, the "local positioning supply means" is not operated in Australia, so that it could not give rise to infringement in Australia. These issues were raised as part of a submission that the proposed March pleading was deficient in providing sufficient facts to enable a determination of the case being advanced. Optus said that the proposed March pleading was 'evasive and ambiguous, and likely to cause prejudice, embarrassment and delay in the proceeding' and failed to disclose a reasonable cause of action.
54 It also complained about the uncertainty of the part of the proposed March pleading which asserted that Optus operated the Optus 2G GERAN that complied with the whole or part of a version of the SUPL Standard. Apart from a failure to identify the part of the SUPL Standard, which could be later particularised or provided in evidence, Optus said that, to Optus' knowledge, it does not operate an SLP and that its network merely serves as a conduit for transmission of data. Accordingly, Optus says, the failure to identify what functionality the Optus network is said to have, was embarrassing. There were other complaints about the lack of detail of the asserted functionality of the Optus network.
55 Additionally, Optus pointed to the integer of the claim, the "special signalling layer". The case made out in the proposed March pleading was that the transmissions on which Voxson relied are sent on a traffic channel of the network. Optus said, simply, that the traffic channel is not a special signalling layer as pleaded. At [408], the proposed March pleading stated, under the heading "Special Signalling Layer", that the messages were transmitted and/or received by the SET on one or more traffic channels. In [408], the proposed March pleading stated that prior to conveying the information to the SLP, the Optus 2G SET received at least a portion of the information contained in the information from the Optus 2G GERAN in messages transmitted on one or more control channels. In [409], it was stated that one or more traffic channels and one or more control channels corresponded to the "special signalling layer" of the claims. There were similar pleadings for 3G and 4G.
56 Optus seized on the definition of 'special signalling layer" as the combination of one or more traffic channels and one or more control channels. However, as pleaded, the control channels were not used for transmitting the necessary messages but were rather used in a prior step, which was not pleaded to constitute the transmission of a local positioning information signal, and it could not be so, because it is not a message. That is, Optus' contention was that the proposed March pleading, on its face, asserted that the third party SLP transmits communications over the traffic channel of the network and not over a control channel, whereas the special signalling layer of the claims was defined as consisting of both traffic and control channels which each carry information which is part of the local positioning information signal as pleaded.
57 Further, Optus submitted that 'a new paradigm' was introduced by the proposed March pleading. This was that a third party supplied a limited form of A-GPS, ie SUPL, and that no primary infringement was alleged against Optus. Alleged secondary liability was based on the assertion that Optus authorised consumers to infringe, because consumers use handsets or SETs that interact with third party SLPs. While secondary liability was pleaded prior to the proposed March pleading, it was in respect of a system implemented by Optus to use the Optus network as the means of infringement.
58 In addition, Optus addressed the case of secondary liability. It characterised the proposed March pleading as asserting acts that are, in substance, the sale of mobile devices (manufactured by third parties) having A-GPS capability, and the provision of access to its mobile network by way of a SIM card for those devices. It said that mere sale of a device which is capable of infringing and non-infringing uses is insufficient to found secondary liability as asserted, and that, as pleaded, the particularised manuals provided by Optus did not assist Voxson's case. Further, it pointed out that any A-GPS communications utilising a third party server are indistinguishable from any other data traffic and that Optus has no knowledge of them, nor does it have power to control such use of its network.
59 Optus provided schematics that set out some of its contentions, as follows:
60 Voxson's response to Optus' position as to the special signalling layer was to say that it would amend that section of the proposed March pleading 'to clarify that one or more traffic and control channels correspond to the "special signalling layer"'. Voxson said that Optus accepted that it provides both traffic and control channels and that SUPL data are transmitted over the Optus network. It submitted that the construction of this integer of the claims is a matter for evidence of the skilled addressee.
61 Voxson provided its own schematic:
62 Voxson made it clear that a combination of one or more traffic channels and one or more control channels provided by the mobile telephone system constitute the special signalling layer. It said that these channels allow for the transfer of messages between the SLP and SET within the mobile telephone system. It said that it does not assert that any communication path outside that system forms part of the integer. It accepted that its amendments 'clarify certain issues raised by Optus'.
63 At the same time, Voxson offered other amendments in relation to certain more minor complaints and responded to others. I am satisfied as to these more minor amendments.
