Section 120(1) of the Trade Marks Act: THE scope of "thermoplastic polymerS (for packaging)"
71 The trade marks "Flexopack" and "Flexopack Australia" used by the First Respondent are deceptively similar to the sign in the Flexopack Registration. Each sign used by the First Respondent includes the word "Flexopack". The Respondents admit that these names are deceptively similar to the Flexopack Registration. Indeed, if it was necessary so to find, I would also be inclined to the view that they were "substantially identical". The real question debated between the parties was the goods or services in relation to which the First Respondent's trade mark was used or applied and whether they fell within the scope of the Flexopack Registration for the purposes of s 120(1).
72 Section 120(1) applies where the infringing use is in relation to goods or services that are the same as those for which the relevant trade mark is registered. Are the goods within the scope of the description of goods for which the trade mark is registered? The question is therefore whether the First Respondent has used its trade mark in respect of "thermoplastic polymers (for packaging)".
73 As I have said, the Flexopack Registration is registered in class 16 in relation to "thermoplastic polymers (for packaging)" (the Designated Goods). It has been so registered from 26 March 2008. Class 16 includes packaging materials.
74 I should say that I enquired of the parties what the Nice Classification said about the ambit of class 16. As a result, it was tendered in evidence (International Classification of Goods and Services, Part II; World Intellectual Property Organization, Geneva, 2006, Ninth Edition). Class 16 specifically refers to this class as including "plastic materials for packaging (not included in other classes)". The explanatory note elaborates by giving examples of "plastic sheets, sacks and bags for wrapping and packaging" (page 16). The List of Goods in the Class Order also referred to "[p]lastic film for wrapping" (page 103). Notwithstanding the contents of this Classification, the Respondents suggested that it was unheard of, if not heretical, to construe the scope of the registration in the light of the Nice Classification. I must say that such a submission surprised me, particularly in light of the Flexopack Registration's express reference to class 16. Now strictly, class 16 first takes its content from Schedule 1 to the Trade Marks Regulations 1995 (Cth) (see also reg 3.1). But Schedule 1 refers to "plastic materials for packaging (not included in other classes)" and the language of the Schedule reproduces the language of the Nice Classification. I do not see why I cannot refer to the Nice Classification as extrinsic material. But in any event, I am satisfied that the Flexopack Registration was identifying a type of plastic material for packaging.
75 What is embraced by the description of the Designated Goods? Is the description of the Designated Goods wide enough to encompass the relevant products sold, offered to be supplied or advertised by the First Respondent? There is no question that its goods are for packaging. But what is embraced by the description "thermoplastic polymers"?
76 A thermoplastic polymer is a type of plastic material that softens and becomes pliable above a specific temperature and which solidifies again upon cooling. This is distinct from a thermosetting polymer which is a plastic material that does not readily melt or decompose on heating. I have written elsewhere in a little more detail on thermosetting polymers. No further detail is necessary for the present context.
77 The Respondents have sought to draw a distinction between single layer and multilayer products and assert that the Flexopack Registration only applies to the former. But no distinction is made in the Designated Goods as to whether the plastic material is formed from multiple layers or single layers. The question is whether the goods sold have a characteristic of being thermoplastic polymers (plural).
78 In my view the evidence establishes that multilayer films are properly within the definition of thermoplastic polymers. I enquired of Mr Gkinosatis the following:
HIS HONOUR: So just to be clear then, your position is that - say you have got three layers and each of the layers consist of perhaps different types of polymers. Putting all the three layers together, you still describe the whole product which is the three layers as a thermoplastic polymer or thermoplastic polymers?
MR GKINOSATIS: Yes.
79 Initially, the evidence provided by Mr Katelis was that he had never heard of multilayer films described as thermoplastic. But this was shown to be incorrect. Indeed, Mr Katelis had filed a trade mark application for a trade mark specifying "co-ex thermoplastic polymers" being multilayered thermoplastic polymers. Mr Katelis subsequently received an examiner's report and responded to it by submitting a declaration of accuracy to IP Australia (exhibits A3 and A4). The Respondents have therefore described their own multilayer films as thermoplastic polymers.
80 The Respondents have asserted that a different meaning should be given to "thermoplastic polymers".
81 First, it is said that to a person familiar with flexible packaging, the word "polymer" naturally refers to a particular type of chemical compound such as polyethylene to take an example. One can agree that a "polymer" can refer to the chemical (indeed the macromolecule itself), but that does not take the matter far. It is divorced from the context that I need to consider where one is looking at a packaging material, rather than the raw chemicals that go to manufacturing the packaging material. Moreover, the use of the description "thermoplastic" makes this clear. It is a reference to the physical properties of the composite material once formed from the chemical(s).
82 Second, it was said that a multilayer film formed from different polymers could be said to be polymeric but not a thermoplastic polymer. But in my view, the evidence did not support the First Respondent's construction.
83 Mr Gkinosatis, who had relevant manufacturing expertise as well as qualifications in polymer chemistry, simplistically explained (I am reciting his evidence rather than endorsing the precision of the explanation):
(a) that a polymerisation reaction forms a polymer by reacting multiple monomer units together to form a series of linked chains; and
(b) the polymer chains for a thermoplastic polymer are then "entangled" together when forming a pellet (the form in which the raw material is provided), film, or other product made from that particular polymer.
84 Mr Gkinosatis said that when forming a multilayered film this involved choosing "different polymers for the different layers". This was also the way that Mr Gkinosatis used the word "polymer" in his affidavits in describing both the Applicant's and the First Respondent's multilayered products, repeating variations of phrases including "[e]ach product is made from thermoplastic polymers" and "[a]ll of these materials used in the manufacturing of shrink bags and films are thermoplastic polymers". Mr Gkinosatis' affidavits included at least two references to the multilayer films as being "thermoplastic polymers". In my view, in context, this was a natural use of the word polymer.
85 The Respondents have referred to the following evidence of Mr Gkinosatis:
COUNSEL FOR THE RESPONDENTS: And if so - turning that around, if someone said to you what polymer is it ---
MR GKINOSATIS: It constitutes from different layers of polymers, thermoplastic polymers. For example, if it's a polypropylene polyethylene, there is one layer of thermoplastic polypropylene and one layer of thermoplastic polyethylene. So if your question is, is it a polymer, polymeric material this structure - yes, it is a thermoplastic polymeric material. It is - can you name by one name this - if it's different five layers, no you have to name with different polymeric structures. But all of them, they make a thermoplastic polymer.
COUNSEL FOR THE RESPONDENTS: Your answer to that is that it makes polymeric material not a polymer. That's correct, isn't it?
MR GKINOSATIS: In my opinion, the terminology is the same - plastic polymer, polymeric material is the same terminology.
86 The Respondents have submitted that this answer supports their position that while a multilayer film may be "polymeric", calling it a "polymer" is not a natural use of that word.
87 The Respondents assert that the word "thermoplastic" most naturally applies to an individual polymer rather than to a product made from layers of different polymers. The Respondents assert that the description "thermoplastic polymers (for packaging)" is a natural description of the products that the Applicant originally sold, namely, polyethylene sheets.
88 I reject the Respondents' arguments limiting the relevant scope to single layer products. In my view they have an air of artificiality for the following reasons:
(a) First, they seek to decontextualise "polymers" from its context of describing a packaging material rather than the raw chemical(s).
(b) Second, it is well apparent from the evidence that people in the industry are using "polymers" to refer to the product made from the raw chemical(s). Moreover, it is not confined to a single polymer.
(c) Third, the contention that the description only includes a single layer film or a film comprised of multiple layers but using the same polymer is too narrow. It is sufficiently broad to include multiple layers, including layers composed of different polymers. Both the text and context of class 16 make that apparent.
89 In summary, and in my view, the First Respondent's clear lidding films, pouches and bags, rewind film and thermoforming film are all goods falling within the scope of the Flexopack Registration. The First Respondent's use of its trade mark in relation to such goods has infringed the Flexopack Registration under s 120(1), subject to any available defences that I will discuss later.
