The question, then, is whether such a user of the oil drop figure as takes place by the exhibition of the films on television involves infringement of the trade marks. It is a question not to be answered in favour of the appellant merely by pointing to the brevity of the occasions when substantial identity is achieved. The assumption I have made means, of course, that if the oil drop figure as appearing in some of the individual frames of the films were transferred as separate pictures to another context the use of the pictures in that context could be an infringement. But the context is all-important, because not every use of a mark which is identical with or deceptively similar to a registered trade mark infringes the right of property which the proprietor of the mark possesses in virtue of the registration. Section 58 (1) of the Trade Marks Act 1955-1958 Cth defines that right as the right to the exclusive use of the trade mark in relation to the goods in respect of which the trade mark is registered; and s. 62 (1) adds that a registered trade mark is infringed by a person who, not being the registered proprietor, or a registered user using by way of permitted use, uses a mark which is substantially identical with or deceptively similar to the trade mark, in the course of trade, in relation to goods in respect of which the trade mark is registered. A use of a mark in an advertisement of goods is a use in the course of trade, and is of course a use in relation to the goods advertised: Henry Heath Ltd. v. Frederick Gorringe Ltd. [1] ; J. B. Stone & Co. Ltd. v. Steelace Manufacturing Co. Ltd. [1] ; Bismag Ltd. v. Amblins (Chemists) Ltd. [2] ; Hardmuth (Great Britain) Ltd. v. Bancroft & Partners Ltd. [3] . But in my opinion it is implied both in s. 58 (1) and in s. 62 (1) that the use which is there referred to is limited to a use of a mark as a trade mark. In many cases of high authority that limitation was held to be implied in provisions, similar in terms to s. 58 (1), in the trade mark legislation of the United Kingdom in force before the enactment of the Trade Marks Act, 1938 U.K.: Edward Young & Co. Ltd. v. Grierson Oldham and Co. Ltd. [1] ; Carless, Capel & Leonard v. F. Pilmore-Bedford & Sons [1] ; J. B. Stone & Co. Ltd. v. Steelace Manufacturing Co. Ltd. [2] ; Champagne Heidsieck et Cie. etc. v. Buxton [3] ; Irving's Yeast-Vite Ltd. v. Horsenail [4] ; see also Saville Perfumery Ltd. v. June Perfect Ltd. [5] , and Aristoc Ltd. v. Rysta Ltd. [6] . The Imperial Acts before 1938 contained no provision corresponding with s. 62 (1); but in the Australian Act of 1905, which in s. 50 repeated the English provision, there was included a provision (in s. 53) that the rights acquired by registration of a trade mark should be deemed to be infringed by the use, in respect of the goods in respect of which it was registered, of a mark substantially identical with the trade mark or so nearly resembling it as to be likely to deceive. The case of Mark Foy's Ltd. v. Davies Coop & Co. Ltd. [7] arose under the 1905 Act, and two members of this Court, applying the reasoning of the English cases, there held that the use referred to both in s. 50 and in s. 53 was use as a trade mark [8] . They treated s. 53 as having no other effect than to make clear on the face of the Act what formerly had been left to case-law, that identity was not necessary for infringement: substantial identity or deceptively close resemblance would suffice. I did not myself have occasion in that case to express an opinion on the point, but I respectfully agree in the view their Honours stated. The present Australian Act differs somewhat from its predecessor of 1905, but not, I think, in any material respect. In particular, s. 58 (1), defining the right conferred by registration as being the right to the exclusive use of the mark, adds never a word to displace the settled interpretation of the expression "use of the mark" in this kind of provision. This is the more significant because the Trade Marks Act, 1938 U.K. had made a provision which, in consequence of a marked difference of judicial opinion as to its meaning, had drawn attention pointedly to the very topic some seventeen years before. That Act had made in s. 4 (1) provisions which may be described, with sufficient accuracy for present purposes, as combining what is found in ss. 58 (1) and 62 (1) of the present Australian Act, but with an important addition to the description of the use which should constitute infringement, namely that it should be use in such a manner as to render the use of the mark likely to be taken either (a) as being use as a trade mark or (b) in certain cases as importing a reference to some person having the right either as proprietor or as registered user to use the trade mark or to goods with which such a person should be connected in the course of trade. These added words gave a clear foothold for a contention that the use referred to in the definition of the exclusive right was no longer limited to use as a trade mark. But even so, some eminent judges considered that the cases under the older legislation still applied, being unable to persuade themselves that so unsatisfactorily drafted a piece of legislation really meant to make the fundamental change which would be involved in converting the right formerly protected by trade mark law into what Simonds J. described as "something akin to a limited form of copyright": Bismag Ltd. v. Amblins (Chemists) Ltd. [1] . A majority of the Court of Appeal thought the intention to make the change sufficiently evinced: [1] . We have not here to choose between the opposing views. What is important is to notice that the draftsman of the Australian Act of 1955 not only refrained from adopting the particular provisions which in England had been held to enable a use otherwise than as a trade mark to be an infringement but, using words to which the earlier English cases had for so long assigned a meaning, abstained from all direct attempt to modify or exclude that meaning. He did introduce into s. 62 (1) the expression "in the course of trade", following in this respect s. 4 (1) of the 1938 Act of the United Kingdom; but presumably the purpose was to ensure that (to take an example) anyone who put petrol not being "Shell" petrol into a can marked "Shell", but without any intention of supplying it to anyone else, should not be held to infringe the trade mark "Shell": see Kerly on Trade Marks, 8th ed. (1960) p. 272. See also Ravok (Weatherwear) Ltd. v. National Trade Press Ltd. [2] . It is not possible, I think, to conclude from this that an intention appears to free the expression "uses a mark" from the limitation which so often and for so long has been recognized as necessarily to be read into it in such a context.
