Consideration
31 I will first consider the period of time Pavetest saved by having access to the UTS software and the UTS communications protocol documents. Insofar as the UTS communications protocol documents are concerned, I have found that the amount of time saved was two to three weeks (see the Reasons at 125). In relation to the UTS software, in 125 and (l) of the Reasons, I said:
(j) Although Mr Li said that, other than code in the UTS system libraries, he did not copy any of the UTS code, there is evidence (discussed below) that version 2 of the TestLab software contains a number of unusual names that may suggest copying beyond the system library. Whether or not Mr Li copied parts of the UTS source code beyond the system library, I think it is likely that he consulted and derived assistance from the UTS test modules that were provided to him.
…
(l) Mr Li gained considerable assistance in the development of the TestLab software from consulting the UTS source code. Mr Li said that, by reusing data structures used by the UTS code, and system library functions, instead of developing these from scratch, he estimated that he saved himself "about a couple of months of development time". This does not take into account the benefit he gained generally from consulting the UTS software. I think it likely that the amount of time saved was considerably greater than two months.
32 At [214] of the Reasons, I said:
In my view, the evidence establishes that Pavetest gained a substantial springboard benefit by the misuse of the confidential information discussed above. Apart from the two to three weeks that were saved by Mr Feeley not having to develop a new communications protocol document, Pavetest saved a substantial amount of time by Mr Li having access to the UTS source code. The benefit gained is not limited to using the UTS source code to educate Mr Li about the problem domain, and the copying of source code as set out in Annex D. I would infer that Mr Li utilised ideas from, and otherwise gained a benefit from examining, other aspects of the UTS source code in writing the TestLab software. Given that he was writing software for the same type of equipment, it would be surprising if he did not draw on other aspects of the UTS source code, notwithstanding the new and more efficient approach to the architecture of the software. Thus, while I accept that he did not copy (in the sense of reproducing the text of) functions in the UTS test modules, I do not accept that he did not draw on other aspects of the UTS source code, including in the test modules, in the course of writing the TestLab software.
33 It is difficult to be precise about the period of the springboard benefit or head start, but based on the evidence as a whole I think it likely that Pavetest would have taken approximately three years to develop the TestLab software had it not had access to the UTS software, compared with the approximately two and half years (from September/October 2012 to April/May 2015 - Reasons, [104], [130]) that it actually took to develop the software. In forming this view, I have taken into account, in particular: the period of time IPC Global took to develop the initial UTS software (about three person-years - Reasons, [48]); the previous experience of the developers of that software (Reasons, [48]); the period of time during which Mr King created 19 test modules for UTS (a period of about a decade - Reasons, [49]); the period of time Pavetest took to develop the TestLab software (about two and a half years - Reasons, [104], [130]); the new and more efficient architecture of the TestLab software (Reasons, 125); Mr Li's lack of experience in the 'problem domain' (Reasons, 125); the period of time during which Mr Li referred frequently to the UTS source code (November 2012 to April 2013 - Reasons, 125); Mr Li's invoices and evidence regarding subsequent reference to the UTS source code (Reasons, 125); and Mr Feeley's experience and expertise. I do not consider the 'clean room' development estimates in section 2.13 of the Fourth Sizer Report to be of much assistance in this regard. The estimates are expressed at a high level of generality. In any event, the estimates provided by Mr Sizer (ie, two to three person-years for PC software development and one person-year for system integration and testing) are consistent with the above estimate, if the lower end of the total of these estimates is adopted. On the basis that it would have taken Pavetest approximately three years to develop the TestLab software had it not had access to the UTS software, compared with the two and half years it actually took, Pavetest gained a springboard benefit or head start of approximately six months. I do not think it necessary to add the period of two to three weeks referred to earlier in this paragraph to the period of approximately six months; it is likely that the two periods would have overlapped.
34 It is appropriate for there to be an inquiry as to monetary relief, whether this be damages (or equitable compensation) or an account of profits, in connection with the misuse of IPC Global's confidential information. However, I do not think it necessary or appropriate to grant a temporary (or springboard) injunction restraining Pavetest from reproduction, importation, supply, sale or offer for supply or sale of version 2 of the TestLab software for a period of time from the date of the orders. My reasons are as follows.
35 The period of the springboard benefit or head start has now passed. If Pavetest had developed the TestLab software without access to the confidential information, it would have completed development of the software in about September/October 2015 (being three years after development commenced). Thus the period of the springboard benefit ended some time ago. In oral submissions, senior counsel for IPC Global sought to address this issue by submitting that version 1 and version 2 of the TestLab software should be viewed as distinct products, and the springboard period commenced when Pavetest started to develop version 2 of the TestLab software (in December 2015 - Reasons, [135]). It was submitted that: Pavetest should have adopted a 'clean room' method for the development of version 2; had it done so, it would have taken four years from that date to develop a new version of the software; hence, Pavetest is still now enjoying a springboard benefit or head start. I do not think this analysis is convincing. In particular, it is artificial, in my view, to view version 1 and version 2 of the TestLab software as two distinct products for present purposes. The labels "version 1" and "version 2" were adopted for convenience to differentiate the software as it existed before and after Pavetest sought to address the issues raised by this proceeding. For the purposes of calculating the springboard benefit that Pavetest obtained, it is appropriate to consider the TestLab software as the relevant product, and assess how long it would have taken Pavetest to develop the software without access to the confidential information and compare this with the time actually taken. On this basis, as indicated above, the period of the springboard benefit has now passed.
36 In these circumstances, granting a temporary injunction is likely to put the applicant, IPC Global, in a better position than if there had been no breach of confidence (and, in any case, would not serve to restore the parties to the competitive position that each would have occupied absent Pavetest's misconduct). On the findings that I have made above, absent the breach of confidence, Pavetest would have entered the market for materials testing equipment in September/October 2015 and would now be competing with IPC Global. The grant of a temporary injunction would likely have the effect of taking Pavetest out of the market, and thus removing Pavetest as a competitor of IPC Global, for the period of the injunction.
37 Further, in considering whether or not it is appropriate to grant a springboard injunction, it is relevant to have regard to the other parts of IPC Global's case (in respect of which it was largely successful) and the relief likely to flow from those other parts. IPC Global succeeded in its copyright infringement case in relation to the firmware and version 1 of the TestLab software. This is likely to lead to monetary relief, either in the form of damages or an account of profits. IPC Global also claims monetary relief in respect of the misuse of its confidential information. This claim arises out of the same events, or course of conduct, as the copyright infringement claims. It is likely, therefore, that any damages or account of profits awarded in respect of copyright infringement will substantially, if not wholly, subsume the monetary relief for breach of confidence. In these circumstances, the grant of a temporary injunction, in addition to the likely monetary relief, may well go further than is necessary to address the misuse of the confidential information.
38 Accordingly, I will not grant a temporary (or springboard) injunction.
