(a) Infringement under s 120(1) of the Trade Marks Act
58 Section 120(1) of the Trade Marks Act provides:
120 When is a registered trade mark infringed?
(1) A person infringes a registered trade mark if the person uses as a trade mark a sign that is substantially identical with, or deceptively similar to, the trade mark in relation to goods or services in respect of which the trade mark is registered.
59 The SUNNY ROO mark was used to sell solar inverters. Although in its pleading SMA alleged infringements of a number of its trade marks, in its final submissions it directed its focus solely on its SUNNY BOY mark. The SUNNY BOY mark is registered in Class 9 for:
Energy supplying devices, essentially comprising transformers, inverters, battery storage and measuring and controlling devices therefore; computer software, namely evaluation software designed for inverter products in photovoltaic installations; all aforementioned goods included in this class.
60 The first question posed under the rubric of s 120(1) is whether BBS used the SUNNY ROO mark 'in relation' to inverters. The second question is whether it so used the mark as a trade mark. That question will receive an affirmative answer when the nature and purpose of the use is examined objectively and an inquiry is then posed as to whether consumers would see the sign as possessing the character of a brand or badge of origin: Nature's Blend Pty Ltd v NestlÉ Australia (2010) 272 ALR 487; [2010] FCAFC 117 per Stone, Gordon and McKerracher JJ at [19].
61 Both of these matters should be answered in SMA's favour. BBS advertised the availability of its inverter range through its SUNNY ROO PRODUCTS website (www.sunnyrooproducts.com). This range included four inverters called the SUNNY ROO SR200TL, the SUNNY ROO SR3000TL, the SUNNY ROO SR4200TL and the SUNNY ROO SR5000TL. The website put the matter this way: '[t]he SUNNY ROO TL range of inverters has been created specifically for the Australian solar market'. The inverters thus marketed bore one of the SUNNY ROO logos which also, obviously enough, contained the name SUNNY ROO. There is no doubt, therefore, that the SUNNY ROO name was used by BBS to sell its inverters and that its use to do so was use of the mark as a trade mark. I did not apprehend that these two aspects of the matter were seriously contested.
62 The real question was whether, as SMA contended, the SUNNY ROO name was deceptively similar to the SUNNY BOY registered trade mark. This directs attention to s 10 of the Trade Marks Act, which provides that 'a trade mark is taken to be deceptively similar to another trade mark if it so nearly resembles that other trade mark that it is likely to deceive or cause confusion'.
63 In my opinion, the name SUNNY ROO so nearly resembles the name SUNNY BOY that it is likely to cause confusion. In reaching that conclusion, I do not put the two marks side by side and ask myself how they look. Rather, I inquire into the impression that persons of ordinary intelligence and memory would have of the name SUNNY ROO based on their recollection of SMA's mark, SUNNY BOY: cf. Shell Company of Australia Ltd v Esso Standard Oil (Australia) Ltd (1963) 109 CLR 407 at 415 per Windeyer J (at trial). I do so cognisant of the fact that there is considerable aural similarity between the two marks and not a small degree of visual similarity. SUNNY appears in both, ROO and BOY are both monosyllabic nouns and each consists, as Mr Darke pointed out, of a consonant followed by a diphthong: cf. Australian Woollen Mills Ltd v FS Walton & Co Ltd (1937) 58 CLR 641 at 658 per Dixon and McTiernan JJ. That similarity is, in effect, a function of the fact that the idea that SUNNY ROO naturally suggests to the mind of a person who sees it - the word combination of the word SUNNY with a short name - is likely to resonate with their recollection, however imperfect, of SUNNY BOY: cf. Jafferjee v Scarlett (1937) 57 CLR 115 at 121-122 per Latham CJ. In that regard, the impact of the word SUNNY in association with goods related to the solar industry should be acknowledged. Relevant, too, is the fact that the SUNNY ROO mark is applied to inverters which are marketed to the public in similar ways, such as via brochures and the internet: cf. Shell at 416; Crazy Ron's Communications Pty Ltd v Mobileworld Communications Pty Ltd (2004) 209 ALR 1; [2004] FCAFC 196 at [87] per Moore, Sackville and Emmett JJ. In particular, it is of significance that BBS sold both its own and SMA's inverters.
64 I have also considered whether the fact that the SUNNY ROO mark incorporates the word SUNNY means that it is possible to say, as SMA does, that it incorporates an essential feature of SMA's mark. This is a different question to whether the word SUNNY in SUNNY ROO is apt to create a similar impression by reason of its association with the sun. I think, on balance, that this is not a matter which assists SMA. In Crazy Ron's, the Full Court gave some consideration to this issue (at [79]-[90]) and, in particular, the advice of Lord Radcliffe in de Cordova v Vick Chemical Co (1951) 1B IPR 496; 68 RPC 103 at 498-499 (IPR); 1055-1056 (RPC) that '[t]he identification of an essential feature depends partly on the court's own judgment and partly on the burden of the evidence that is placed before it'. That tells one what to look at, but not necessarily where to go. The cases perhaps provide more guidance by way of illustration. In de Cordova itself, 'Vapo Rub' was held to be an essential feature of the trade mark 'Vicks VapoRub' because it was commonly used by the public to describe the product. In Crazy Ron's, the Full Court asked itself (at [98]) what the dominant idea conveyed by the mark to a casual observer would be and concluded, by inspection, that the phrase CRAZY JOHN was not an essential feature of the following mark:
65 I do not think that the dominant idea conveyed to the casual observer by the SUNNY BOY mark is the word SUNNY. Nor do I think that SMA's use of the word SUNNY to market its product has reached a level where it could be said that the mark had become 'notoriously so ubiquitous and of such long standing that consumers must be taken to be familiar with it': cf. Crazy Ron's at [99], quoting CA Henschke & Co v Rousemount Estates Pty Ltd (2000) 52 IPR 42; [2000] FCA 1539 at 66 [52] per Ryan, Branson and Lehane JJ.
66 However, I do not think that conclusion detracts from the other matters to which I have referred. Those matters generate a real and tangible risk of deception or confusion arising. The reality of that risk is confirmed by the fact that consumers have, in fact, been misled. In that regard, I refer to the evidence of the erroneous returns of a SUNNY ROO inverter to SMA for repair together with the other evidence of consumer confusion in telephone calls to SMA Australia: see above at [31]. This is a matter of considerable weight: see Australian Woollen Mills at 658 per Dixon and McTiernan JJ.
67 For those reasons, I conclude that deceptive similarity is established.
68 In the case of the name SUNNY ROO PRODUCTS, I accept a similar conclusion. The addition of the word 'products' does not retrieve the situation.
69 In the case of the use of the two SUNNY ROO FROM BYRON BAY and SUNNY ROO AUSTRALIA logos, matters are more complex. There is little doubt that the depiction of Sunny in these logos reduces the visual similarity of the marks. But the aural similarity remains essentially unchanged. Although I accept that the difficulty is not so extreme in the case of these marks, on balance, I still accept SMA's case that these logos are deceptively similar to the SUNNY BOY mark. The principal reason I accept SMA's submission is because deceptive similarity may arise where consumers are caused to wonder or to entertain a reasonable doubt as to whether the products bearing the marks might not come from the same trade source: Southern Cross Refrigerating Company v Toowoomba Foundry Pty Ltd (1954) 91 CLR 592 at 594-595 per Kitto J (at trial) and 608 per Dixon CJ, McTiernan, Webb, Fullager and Taylor JJ (on appeal). As Kitto J observed in that case (at 595) 'it is enough if the ordinary person entertains a reasonable doubt'. My conclusion to that effect is borne out by the fact that a BBS inverter was returned to SMA even though it had the logo on it.
70 I accept, therefore, that each use of the SUNNY ROO brand impugned by SMA infringed SMA's SUNNY BOY mark where utilised in relation to inverters.
