Analysis
77 We do not see this appeal as raising any significant question of principle, despite the fact that the appellants and IPTA have made oblique attacks on the correctness of Research Affiliates and RPL Central by resort to possible interpretations which, ultimately, they dismiss as misinterpretations. Having regard to the particular submissions made by the parties and the interveners on this question, we do not think that the correctness of those decisions is seriously in doubt. In truth, the burden of this appeal lies in whether the primary judge correctly applied them to the case at hand. This appeal does not provide the occasion for this Court to set out the metes and bounds of patentable computer-implemented inventions, assuming that be an appropriate task: see, in that regard, the cautionary observations of the plurality in Myriad at [18].
78 We commence our analysis by noting certain propositions which are not, and cannot be, in dispute.
79 First, in NRDC, the High Court made plain that, in the context of considering whether a claimed invention is a manner of manufacture, the inquiry is not into the meaning of words but into the breadth of a concept which the law has developed by its consideration of the text and purpose of the Statute of Monopolies. The High Court said (at 269):
… One may remark that although the Statute spoke of the inventor it nowhere spoke of the invention; all that is nowadays understood by the latter word as used in patent law it comprehended in "new manufactures". The word "manufacture" finds a place in the present Act, not as a word intended to reduce a question of patentability to a question of verbal interpretation, but simply as the general title found in the Statute of Monopolies for the whole category under which all grants of patents which may be made in accordance with the developed principles of patent law are to be subsumed. It is therefore a mistake, and a mistake likely to lead to an incorrect conclusion, to treat the question whether a given process or product is within the definition as if that question could be restated in the form: "Is this a manner (or kind) of manufacture?" It is a mistake which tends to limit one's thinking by reference to the idea of making tangible goods by hand or by machine, because "manufacture" as a word of everyday speech generally conveys that idea. The right question is: "Is this a proper subject of letters patent according to the principles which have been developed for the application of s. 6 of the Statute of Monopolies?"
80 Thus, when determining whether a claimed invention is a manner of manufacture, a question of characterisation of the invention is involved. However, the question of characterisation is the broad question posed by the High Court: whether the invention is proper subject matter according to the principles developed for the application of section 6 of the Statute of Monopolies.
81 Secondly, this question of characterisation is to be addressed as a matter of substance, not merely as a matter of claim form. In Myriad, Gageler and Nettle JJ so held at [145], adopting an observation by the Full Court to that very effect in Research Affiliates at [107]. The plurality in Myriad at [87] - [88] and [94] also emphasised the need to approach the characterisation of the invention as a matter of substance, saying:
94 Although it may be said in a formal sense that the invention as claimed, referring to isolated nucleic acids, embodies a product created by human action that is not sufficient to support its characterisation as a manner of manufacture. The substance of the invention as claimed and the considerations flowing from its substance militate against that characterisation. To include it within the scope of a "manner of manufacture" involves an extension of that concept, which is not appropriate for judicial determination. …
82 Thirdly, the plurality in Myriad accepted (at [21]) that the analysis of the invention in NRDC by reference to the notion of a "vendible product" can be explained because of "the qualities of the invention before the court". As we have also noted, the Commissioner's argument in NRDC was directed to an application of the "rule" articulated by Morton J in GEC. It is not surprising therefore that the High Court in NRDC discussed the question before it in terms which reflected the substance of the arguments which the parties had, in fact, advanced or addressed. However, the High Court clearly articulated the broad scope to be given to the notion.
83 Fourthly, three propositions emerge from [20] of the reasons of the plurality in Myriad that are particularly pertinent to the present appeal. The first is that the terminology of an "artificially created state of affairs of economic significance", as used in NRDC, was not intended to be, and should not be seen as, a definition of "manner of manufacture" given that, in the same case, the High Court "had denounced the idea of an exact formula". The second proposition is that the terminology is not an exhaustive formulation of the concept of manner of manufacture. The third and related proposition is that satisfaction of such a formulation does not, in any event, mandate a finding of inherent patentability, although "[this] is not to say that it will not suffice for a large class of cases in which there are no countervailing considerations".
84 Against the background of these propositions, the plurality in Myriad at [21] made specific reference to CCOM where the Full Court had said (at 295):
The NRDC case at 275-277 requires a mode or manner of achieving an end result which is an artificially created state of affairs of utility in the field of economic endeavour. In the present case, a relevant field of economic endeavour is the use of word processing to assemble text in Chinese language characters. The end result achieved is the retrieval of graphic representations of desired characters, for assembly of text. The mode or manner of obtaining this, which provides particular utility in achieving the end result, is the storage of data as to Chinese characters analysed by stroke-type categories, for search including "flagging" (and "unflagging") and selection by reference thereto.
85 The plurality said that this formulation, like Morton J's vendible product "rule", should be taken as a guide rather than as a rigid formula.
86 In a similar vein, Gageler and Nettle JJ said (at [125]) that the High Court's references in NRDC to "artificial state of affairs" and "economic utility" in the passage we have quoted at [39] above are not to be taken as suggesting that these are the only considerations relevant to whether a claimed invention is a manner of manufacture for the purposes of the Act. At [126], their Honours explained that a manner of manufacture must be "something more than a mere discovery" and that "(t)he essence of invention inheres in its artificiality or distance from nature". While these remarks were no doubt made with the particular invention in that case in mind, they are no less apposite to all cases where patentable subject matter is to be distinguished from avowedly unpatentable subject matter, including where the latter is mere abstract information.
87 In Grant, the patentee argued that his claimed method (a method of asset protection which utilised a trust, a gift, a loan and a security) was a manner of manufacture because it involved the creation of an artificial state of affairs with economic utility. The Full Court did not accept that characterisation of the claimed method and concluded that a "physical effect in the sense of a concrete effect or phenomenon or manifestation or transformation" was required in order to support its patentability: see at [32]. The claimed method did not exhibit such an effect. In reasoning to that conclusion, the Full Court said at ([30] - [32]):
30 Contrary to Mr Grant's submission, the method of his patent does not produce any artificial state of affairs, in the sense of a concrete, tangible, physical, or observable effect. It is quite different from the invention in Catuity, which was a method involving components such as smart cards and point of sale terminals, and produced tangible results in the writing of new information to the Behaviour file and the printing of the coupon (at [128]). While there was not a physically observable end result in the sense of a tangible product, the invention involved an application of an inventive method where part of the invention was the application and operation of the method in a physical device. Within the concept of NRDC an artificial state of affairs was produced, a state of affairs created by the application or effect of the method.
31 What Mr Grant's method results in is at best an abstract, intangible situation, namely that a hypothetical unsecured creditor who recovered judgment against a user of the method could not levy against the user's assets to the extent they were subject to the charge. (We say at best because the application of the Bankruptcy Act 1966 (Cth) preference provisions and the laws against fraudulent conveyances have not been considered in this litigation; see Trustees of the Property of Cummins (a bankrupt) v Cummins (2006) 224 ALR 280 at [21]-[24].)
32 A physical effect in the sense of a concrete effect or phenomenon or manifestation or transformation is required. In NRDC, an artificial effect was physically created on the land. In Catuity and CCOM as in State Street and AT&T, there was a component that was physically affected or a change in state or information in a part of a machine. These can all be regarded as physical effects. By contrast, the alleged invention is a mere scheme, an abstract idea, mere intellectual information, which has never been held to be patentable, despite the existence of such schemes over many years of the development of the principles that apply to manner of manufacture. There is no physical consequence at all.
88 We do not read these passages as straying from the propositions we have drawn from Myriad. It can be seen that, in these paragraphs, the Full Court was seeking to explain why a mere "abstract, intangible situation" is not a manner of manufacture, and hence not a patentable invention. Although the Full Court referred to the need for a "physical effect", it is abundantly clear that their Honours used the word "physical" in a very broad or extended sense. It is apparent that their Honours did so in an endeavour to demark, as best as words can, the conceptual distinction between, on the one hand, a manner of manufacture and, on the other, "a mere scheme, an abstract idea, mere intellectual information, which has never been held to be patentable …": see at [32]. We see the Full Court's reference to, and use of, "physical effect" to be in no way different to the High Court's reference to, and use of, "physical phenomenon" in the passage from NRDC we have quoted at [38] above.
89 The appellants submitted that there is an apparent inconsistency between the conclusion of the Full Court in Grant and "the principle in CCOM and Catuity". We see no inconsistency. Indeed, in Grant the Full Court accepted (at [32], quoted above) that CCOM and Catuity both concerned methods where a component was physically affected or a change in state or information in a part of a machine was involved. In doing so, their Honours made clear that the requirement of a "physical effect" did not mean that the method must result in a tangible product as such.
90 But perhaps more importantly for present purposes, the reasons of the plurality in Myriad make it perfectly clear that CCOM should not be taken as laying down a rule or rigid formula to be adhered to when characterising the claimed invention, although recourse to the terminology of an "artificially created state of affairs of economic significance" can be taken as a guide when analysing the true character of the invention that is claimed. Even then, it does not follow that the demonstration of a physical effect mandates patentability.
91 The decisions, and the language used, in Research Affiliates and RPL Central must be understood likewise. In each case, the Full Court was seeking to describe the conceptual distinction between a manner of manufacture and an unpatentable abstraction. In each case, the Full Court was explaining that a claimed method that is unpatentable does not change its legal character merely because the method is implemented by the instrumentality of a computer.
92 Thus, in Research Affiliates the Full Court also said (at [107]):
107 The determination whether the claimed invention is truly "an artificially created state of affairs" in satisfaction of NRDC is made not by some mechanistic application of the criterion of artificiality or physical effect, but by an understanding of the claimed invention itself. The invention is to be understood as a matter of substance and not merely as a matter of form.
93 This statement is consonant with the approach subsequently approved by the High Court in Myriad. Indeed, as we have noted at [81] above, the correctness of this statement by the Full Court was acknowledged by Gageler and Nettle JJ.
94 In considering whether the mere implementation by a computer of an abstract idea or scheme is enough to transform unpatentable subject matter into patentable subject matter, the Full Court in Research Affiliates (at [115]) resorted to the language of "artificial" or "physical" effects, "technical contribution" and suchlike expressions, as used by the High Court in NRDC. By resorting to this language, the Full Court was doing no more than explaining that the claimed method in that case did not transcend, as a matter of substance, what remained an abstract idea or mere information of a kind that has never been considered to be patentable subject matter under Australian law.
95 In RPL Central, which was decided after Myriad, the Full Court again dealt with the question of whether the computer implementation of an unpatentable abstract idea is sufficient to confer patentable subject matter. At [96], the Full Court said:
96 A claimed invention must be examined to ascertain whether it is in substance a scheme or plan or whether it can broadly be described as an improvement in computer technology. The basis for the analysis starts with the fact that a business method, or mere scheme, is not, per se, patentable. The fact that it is a scheme or business method does not exclude it from properly being the subject of letters patent, but it must be more than that. There must be more than an abstract idea; it must involve the creation of an artificial state of affairs where the computer is integral to the invention, rather than a mere tool in which the invention is performed. Where the claimed invention is to a computerised business method, the invention must lie in that computerisation. It is not a patentable invention simply to "put" a business method "into" a computer to implement the business method using the computer for its well-known and understood functions.
96 After noting that the respondent in that case did not claim any invention or ingenuity in any program or operation of a computer, or implementation by a computer to operate the method (although the method did utilise the speed, processing power and ability of a computer), the Full Court concluded (at [113]) that the claimed invention was, in substance, "a scheme or a business method that is not properly the subject of letters patent".
97 Further, after noting that Myriad had elaborated on the principles to be applied when considering whether a claimed invention is a manner of manufacture, the Full Court said (at [116]):
116 As their Honours observed in [Myriad] (at [18]), the question whether a claim is as to patentable subject matter in accordance with the principles developed for the application of s 6 of the Statute of Monopolies is answered according to "a common law methodology under the rubric of 'manner of manufacture'", as exemplified by NRDC. In this context, their Honours emphasised (at [20]) that, while satisfaction of an "artificially created state of affairs of economic significance" as stated in NRDC may "suffice for a large number of cases in which there are no countervailing considerations", this terminology is not to be treated as a formula exhaustive of the concept of manner of manufacture, or a formula which alone captures the breadth of the ideas to which effect must be given. Similarly, Gageler and Nettle JJ noted (at [125]) that the holding in NRDC does not mean that an "artificial state of affairs" and "economic utility" are the only relevant considerations in this context. However, the majority and Gageler and Nettle JJ acknowledged the usefulness of such characterisation in appropriate circumstances.
98 The Full Court continued by explaining its use of language (at [117]):
117 Where we refer in these reasons to the terminology in NRDC, we do so to explain the qualities of the invention being considered, as was done in Research Affiliates and in CCOM - as acknowledged in [Myriad] at [21] per French CJ, Kiefel, Bell and Keane JJ and by Gordon J at [273]. In this case, as in Research Affiliates, reference to the terminology used in NRDC is apposite, although, as we have explained, not conclusive of patentability.
99 Turning to the present case, we accept the respondent's submission that the method claims in suit are, in truth, no more than an instruction to apply an abstract idea (the steps of the method) using generic computer technology. The appellants endeavoured to explain why the claimed method falls within the notion of an artificially created state of affairs by attributing computer functionality to the method: the computer (or, in the language of the claims, the electronic processing device) searches remote data sources; the computer generates a network representation; and the computer responds to a user's selection to conduct a further search. The appellants also attributed computer functionality to the method by the computer determining additional information relating to the same entity. As we have previously noted, this involves the contentious question of "entity matching" - a step which the primary judge found was not a step in the claimed method. We discuss this below when dealing with the grounds relating to innovative step. But even if for present purposes "entity matching" is taken to be a step in the claimed method, neither it nor the other steps, individually or collectively, amount to anything more than a method in which an uncharacterised electronic processing device (for example, a computer) is employed as an intermediary to carry out the method steps - where the method itself is claimed in terms which amount to no more than an abstract idea or scheme.
100 In oral submissions, the appellants sought to make much of the fact (if it be a fact) that the claimed method cannot be implemented using "generic software". The difficulty with this submission is that the claims in suit do not secure, as an essential feature of the invention, any particular software or programming that would carry out the method. It is left entirely to those wishing to use the method to devise, and then to implement, a suitable computer program for that purpose. As we have said, all that the specification teaches is that the processing system be "suitably programmed".
101 As the oral argument developed during the appeal, the appellants submitted that the claimed method is, itself, a high-level description of a computer program. We do not accept this characterisation. If approached from this point of view, the method is really an idea for a computer program, it being left (as we have said) to the user to carry out that idea in an electronic processing device. Indeed, the method, as claimed, is no different in principle to the methods claimed in Research Affiliates and RPL Central. Patentable subject matter is not provided simply because the method is a "method … in an electronic processing device", which itself is not characterised. To find otherwise would be to elevate form over substance.
102 This conclusion applies equally to the apparatus claims which provide no more than an uncharacterised apparatus (which includes an uncharacterised electronic processing device) to carry out the steps of the abstract method.
103 As we have noted, the primary judge accepted (at [192]) that the method brings about an artificially created state of affairs in the sense that network diagrams are generated from querying remote data sources, and that this state of affairs is economic in character. However, he reasoned that this alone would not be enough to constitute the claimed method as a manner of manufacture. His Honour did so in reliance on the following passage from Research Affiliates (at [102]):
102 … the relevant inquiry is not into the form of the words to determine whether what is claimed is properly the subject of a patent. If a process is to be patentable, it must offer some advantage which is material, in the sense that the process belongs to a useful art. The characterisation of patentability by reference only to the description in NRDC of a product which consists of an artificially created state of affairs of economic significance was part of the High Court's reasoning but did not represent a sufficient or exhaustive statement of the circumstances in which a claimed invention is patentable.
104 Once again, this passage is consonant with the approach approved in Myriad. His Honour did not err, therefore, in adopting that approach.
105 As we have recorded (at [55] - [61] above), the appellants criticised the primary judge for inquiring whether the claimed method results in "an improvement in the computer". This was an allusive reference by his Honour to a statement made in Research Affiliates that there is a distinction between mere implementation of an abstract idea in a computer and the implementation of an abstract idea that creates an improvement in the computer. The context in which this distinction is expressed is found at [104] - [106] in Research Affiliates:
104 As Thomas J said in Alice Corporation, there is a distinction, between mere implementation of an abstract idea in a computer and implementation of an abstract idea in a computer that creates an improvement in the computer. There is also a distinction between, on the one hand, a method involving components of a computer or machine and an application of an inventive method where part of the invention is the application and operation of the method in a physical device and, on the other, an abstract, intangible situation which is a mere scheme, an abstract idea and mere intellectual information.
105 A useful description of the distinction to be drawn was set out by Lourie J in Bancorp Services LLC v Sun Life Assurance Company of Canada 687 F (3d) 1266 at 1277, 1278 (2012) (citations omitted):
"Modern computer technology offers immense capabilities and a broad range of utilities, much of which embodies significant advances that reside firmly in the category of patent-eligible subject matter. At its most basic, however, a 'computer' is 'an automatic electronic device for performing mathematical or logical operations'. As the Supreme Court has explained, '[a] digital computer … operates on data expressed in digits, solving a problem by doing arithmetic as a person would do it by head and hand'. Indeed, prior to the information age, a 'computer was not a machine at all'; rather, it was a job title: 'a person employed to make calculations'. Those meanings conveniently illustrate the interchangeability of certain mental processes and basic digital computation, and help explain why the use of a computer in an otherwise patent-ineligible process for no more than its most basic function - making calculations or computations - fails to circumvent the prohibition against patenting abstract ideas and mental processes. As we have explained,'[s]imply adding a "computer aided" limitation to a claim covering an abstract concept, without more, is insufficient to render the claim patent eligible'.
To salvage an otherwise patent-ineligible process, a computer must be integral process [sic], a computer must be integral to the claimed invention, facilitating the process in a way that a person making calculations or computations could not."
(Emphasis added.)
106 The use of a computer necessarily involves the writing of information into the computer's memory. This means that there are a number of "physical effects" in the sense of transformed data and memory storage during the claimed process. The claimed index in this case is data that exist in computer-readable form. The question is whether this is sufficient to make the claimed method properly the subject of letters patent. …
106 The passage in Thomas J's reasons when delivering the opinion of the Supreme Court of the United States in Alice Corporation is:
Considered "as an ordered combination," the computer components of petitioner's method "ad[d] nothing … that is not already present when the steps are considered separately." Id., at 79. Viewed as a whole, petitioner's method claims simply recite the concept of intermediated settlement as performed by a generic computer. See 717 F. 3d, at 1286 (Lourie, J., concurring) (noting that the representative method claim "lacks any express language to define the computer's participation"). The method claims do not, for example, purport to improve the functioning of the computer itself. See ibid. ("There is no specific or limiting recitation of … improved computer technology …"); Brief for United States as Amicus Curiae 28-30. Nor do they effect an improvement in any other technology or technical field. See, e.g., Diehr, 450 U.S., at 177-178. Instead, the claims at issue amount to "nothing significantly more" than an instruction to apply the abstract idea of intermediated settlement using some unspecified, generic computer. Mayo, 566 U.S., at 79. Under our precedents, that is not "enough" to transform an abstract idea into patent-eligible invention. Id., at 77.
107 The primary judge's inquiry at [193] as to whether implementation of the claimed method results in "an improvement in the computer" must be seen in the context of the corresponding and more fulsome discussion in Research Affiliates to which his Honour alluded. As can be seen, the discussion in Research Affiliates was directed to elucidating the distinction between mere schemes, abstract ideas and intellectual information on the one hand, and on the other, possibly patentable, subject matter.
108 This inquiry must also be seen in the context of his Honour asking concurrently and alternatively the question posed in RPL Central: does the claimed method "merely require generic computer implementation"? This last-mentioned aspect of the primary judge's inquiry is significant because if, on proper analysis, and as a matter of substance, the claimed method "merely require[s] generic computer implementation" (as in our view it does) then the method cannot be a manner of manufacture. We do not understand the appellants to contend otherwise.
109 Thus, his Honour's reference at [193] to whether the claimed method results in "an improvement in the computer" is to be understood as an inquiry into and search for possibly patentable subject matter by reference to a touchstone of such subject matter. So, too, should the primary judge's inquiry at [195] as to whether the claimed method results in an improvement in "the functionality of the machine".
110 So understood, we see no error in his Honour's approach. Indeed, the appellants' submissions advance the proposition that patentable subject matter does exist in respect of the claimed methods because of computer functionality. However, contrary to the appellants' submission, we do not read the terms in which the primary judge couched this inquiry as signifying that his Honour was seeking to import any particular test into his consideration. In particular, we do not understand his Honour to have been positing a hardware-specific test, as the appellants suggested in oral submissions. The primary judge was simply directing his mind to whether the claimed invention was something more than mere "generic computer implementation" of an otherwise abstract idea.
111 The appellants submitted that, by describing (at [195]) the claimed method as a concatenation of three other known methods, the primary judge misstated the integers of the claims and failed to consider the working interrelationship of the claimed combination. These submissions proceed from a somewhat over-meticulous analysis of this part of his Honour's reasons and, perhaps, a misunderstanding of the task his Honour was setting himself. As we have said, in this part of his reasons the primary judge is to be understood as inquiring into and searching for possible patentable subject matter, such that the claimed method was something more than "generic computer implementation" of an abstract idea. It can be accepted readily that the three methods of the concatenation to which his Honour referred might not, in terms, encompass all the individual steps of the claimed method. However, we do not read his Honour's reasons as suggesting that they did. We also do not read his Honour's reasons as focusing on individual features of the claimed method at the expense of considering the effect of their combination.
112 It is true that, at [194] - [197], the primary judge made a number of statements about whether the method and apparatus described in the specifications resulted in a computer being used to do something it has not been used to do before. His Honour also described the "enhanced user experience" afforded by the invention as resulting from a "combination of well-known computing mechanisms". We accept that his Honour's use of this language suggests that other, conceptually distinct elements of patentability might have intruded into his Honour's consideration of whether the claimed method and apparatus were directed to a manner of manufacture: see, for example, the caution expressed in CCOM at 291, which was repeated in Research Affiliates at [111]. But, at the end of the day, we see no error in his Honour's ultimate conclusion that no manner of manufacture is involved in the method and apparatus as claimed.
113 For these reasons, Grounds 1 - 7 of the appeal fail.
