Assessment of Mr Simons' evidence
136 TiVo placed considerable reliance upon the evidence of Mr Simons which, it submitted, should be given "great weight". In oral submissions Senior Counsel for TiVo put his submission in relation to this evidence in this way:
We say that there are two marks. The only distinguishing feature is the first consonant. We say that the people who ought to know the difference are the people who are confused and the time of the confusion, of course, is when they had both products but they were confused. They thought one was the other. If they think that, in a non-pressured environment, then how do they deal with the consumer? If a consumer says, "Is this the same as the Tivo I've read about", they're going to say, "Aren't they the same thing?" Isn't there a good prospect of that? And the answer, we say, is yes there is.
137 It is well established that evidence of actual confusion may be highly persuasive. But as with other evidence, in assessing what weight should be given to it, the Court must evaluate the quality of the evidence by reference to its internal features, the other evidence and the Court's own knowledge of human affairs. In Australian Woollen Mills Ltd v FS Walton & Co Ltd at 658, upon observing that "[e]vidence of actual cases of deception, if forthcoming, is of great weight", Dixon and McTiernan JJ went on to dismiss evidence from a few people who mistook a newspaper advertisement of the respondent for an advertisement of the appellant on the basis that it "amounted … to very little."
138 There is little point speculating about why Mr Simons was not cross-examined. But it is important to remember that he gave evidence of what staff at various Dick Smith stores said and did in response to him introducing himself as "Peter from TiVo". He might have been cross-examined with a view to eliciting more about what those people said and did, but he could not give direct evidence of their state of mind or their reasons for responding to him in the way they did. Nevertheless, the usual consequences follow from the failure to cross-examine Mr Simons: first, it was not open to Vivo to submit that Mr Simons' affidavit evidence was untruthful; secondly, Mr Simons' affidavit evidence was not contradicted or qualified by any other evidence, including, in particular, oral evidence that might have been elicited from him in cross-examination.
139 A court is not bound to accept evidence that has not been the subject of cross-examination. In Ellis v Wallsend District Hospital (1989) 17 NSWLR 553 at 588-589, Samuels JA (with whom Meagher JA agreed) rejected the view that evidence unchallenged by cross-examination must be accepted unless it was inherently improbable. In his Honour's view, a court may decide not to accept such evidence whether or not it is inherently improbable though it may, of course, be wrong, unreasonable or perverse not to accept such evidence in a given case. Samuels JA's views were endorsed by Kirby A-CJ (as his Honour then was) in Elkington v Shell Australia Ltd (1993) 32 NSWLR 11 at 17.
140 It is clear from Mr Simons' account of his conversation with the member of the sales staff at the Dick Smith store at Campbelltown that this person thought there was some connection between TiVo and Vivo even after Mr Simons had made it clear that he was from TiVo rather than Vivo.
141 The position is a little less clear in the case of Mr Simons' conversation with the store manager at the Dick Smith store at Menai. However, Mr Simons' evidence suggests that the manager with whom he spoke also thought there was some connection between TiVo and Vivo even though he was familiar with both trade marks and the products to which they were applied.
142 I do not consider Mr Simons' account of his conversations at the Dick Smith stores to be evidence of confusion occurring as a result of differences in pronunciation, slurring, mishearing or imperfect recollection. None of these possibilities explain why the confusion referred to in Mr Simons' evidence occurred. How then is his evidence to be explained?
143 I have difficulty understanding why a sales person who was familiar with the products he or she was selling would think that the TiVo products and the Vivo products were the same or that they came from the same source unless he or she mistook one mark for the other. It seems to me extremely unlikely that sales staff who were mindful of the differences (both visually and aurally) between the two marks would believe that goods marked with one mark came from the same source as goods marked with the other. Nor do I think that sales staff would be caused to wonder whether or not the goods came from the same source in such circumstances.
144 This brings me to the relevance of Mr Simons' evidence to this appeal. As I have mentioned, TiVo did not challenge the primary judge's rejection of its case based upon any visual similarity between the marks, but sought only to uphold the primary judge's finding of deceptive similarity on the basis of their strong aural similarity. It follows, in my view, that TiVo must be taken to accept that use of the Vivo mark in a normal and fair manner on audio-visual equipment would not of itself give rise to any tangible risk of confusion except in circumstances where sales staff and customers also used the mark orally, which was something that the primary judge found (at para [176]) occurred in a significant number of cases.
145 There may be situations in which a mark may be found to be deceptively similar to another mark even though the differences between them would be readily apparent to the consumer: see, for example, the trade marks in issue in In the Matter of John Fitton & Co Limited's Application (1949) 66 RPC 110 (JESTS and EASYJESTS) (UK Reg.); Tonka Corporation v Chong (1994) 29 IPR 253 (MONOPOLY and MUSICOPOLY) (Reg.); Telstra Corporation Ltd v Yellownet Corporation (1999) 44 IPR 415 (YELLOW PAGES and YELLOWNET) (Reg.); and Caterpillar Inc v Amco (Vic) Pty Ltd (2000) 49 IPR 407 (CAT and LANDCAT) (Reg.).
146 In Polo Textile Industries Pty Ltd v Domestic Textile Corporation Pty Limited (1993) 42 FCR 227 (POLO and POLO CLUB) Burchett J held (at 230) that POLO CLUB was deceptively similar to POLO because (inter alia) "someone who knew of a 'Polo' product, upon seeing a similar product selling under the name 'Polo Club' would be quite likely to think it was a particular version of the product which could be described as the Club version." Similarly, in Pfizer Products Inv v Karam (2006) 237 ALR 787 (VIAGRA and HERBAGRA) Gyles J held that the mark HERBAGRA was deceptively similar to the mark VIAGRA because a substantial number of members of the public would think products bearing the former mark were a "herbal version" of VIAGRA: see para [38] of Gyles J's reasons.
147 While I can readily understand why consumers might think there is an association between products marked POLO and those marked POLO CLUB, or products marked HERBAGRA and those marked VIAGRA, it is much more difficult to see why a consumer would understand there to be such an association between the two marks in issue in the present case.
148 The primary judge appreciated that the confusion described in Mr Simons' evidence was "not plausibly explicable as a result of mishearing" (at para [182]). Even so, her Honour's decision on the issue of deceptive similarity was not based upon contextual confusion of the type to which I have referred, but phonetic similarity and the impact of careless pronunciation and imperfect recollection. As the primary judge said (at para [179]):
In my opinion, allowing for imperfect recollection, careless pronunciation, the range of goods (and services) covered by the registrations, and the context and circumstances of promotion, advertising and sale, the visual differences between the marks are not sufficiently compelling to overcome the impact of the strong aural similarity in the purchasing environment.
149 In oral submissions Senior Counsel for TiVo argued that manufacturers sometimes use more than one trade mark. In the course of explaining why Mr Simons' evidence should not be regarded as inherently improbable Senior Counsel then said:
They might use multiple related trademarks. They might be regarded as so close that they have to come from the same source. It's not inherently improbable.
150 In my opinion, the present case is quite unlike the "contextual confusion" cases to which I have referred. Where marks have been refused registration on account of "contextual confusion" in the past, the mark in question has usually incorporated the whole of a registered mark or some distinctive component of the registered mark which has been coupled with some additional descriptive element, all of which will suggest that the marks are related in some way, even though they are perceived to be different. I do not think a person who was mindful of the difference between the marks in issue in this case would think, or wonder whether, the marks (and therefore the goods to which they are applied) were related.
151 Mr Simons' evidence suggests to me that there was some other factor at work that may explain why the Dick Smith staff with whom he spoke may have thought that the TiVo and Vivo products were from the same source. In the absence of evidence from the sales staff concerned or other evidence that might explain why they thought as they did, I am not persuaded that Mr Simons' evidence should be given any significant weight.
