Evidence
20 The defendants relied upon reports from Dr Wynn-Hatton. Dr Wynn-Hatton had been a chemist in industry for 15 years and had been involved in the development and launching of new products in this field. His expertise was not challenged.
21 He said that the successful performance of any product in the laundry/cleaning market was multi-dimensional and did not rely upon a single product attribute alone. He thought that market performance encompassed more than just the ability of the product to meet the consumer expectation of removing a stain from a fabric.
22 Doctor Wynn-Hatton's evidence was directed to the new laundry products to be launched in the domestic market. He identified the following qualities which were asserted for these products:
· Superior ability to remove stains from fabric.
· Containing special enzymes.
· Possessing a superior shelf life.
· Is concentrated.
· Is fully biodegradable.
· Possessing superior environmental benefits.
· Having no petrochemical derived components.
· Possessing softening qualities.
· Possessing anti-wrinkling qualities.
· Providing easy ironing.
· Providing ultraviolet protection.
· Possessing sterilising/sanitising ability.
· Providing colour brightening and protection for coloured items.
· Possessing stain blockers.
· Possessing softening qualities.
23 Doctor Wynn-Hatton's contention was that many of those performance claims could not be assessed by comparative testing alone. It was his opinion that such tests would yield information about one characteristic of the products' likely market performance but could not identify individual formulations so that there was no way of determining how the result was obtained. He thought it was necessary to have the relevant formulation and method of manufacture to ensure that the stated wash test performance was consistent with the composition.
24 In this field of expertise a distinction is drawn between the formula and the manufacturing process. The formula will identify the component parts of a product and their quantity. Information about the order in which the components are mixed is regarded as part of the manufacturing process (T.74-75).
25 It was the opinion of Dr Wynn-Hatton that the testing of products could not identify the presence and performance of active enzymes. This was important because it was the active enzymes which gave to a product its cleaning capacity. Similarly, Dr Wynn-Hatton thought that testing could not determine the presence and performance of stain blockers in a product. On these issues he differed from Professor Pailthorpe and Dr Crank, the company plaintiffs' experts.
26 It was the opinion of Dr Wynn-Hatton that no information as to the stability of the enzymes in the product could be obtained from testing. Detailed knowledge of the composition was required to assess enzyme stability and hence market performance. He was of the opinion that testing would give no information about the environmental performance or credentials of a product. Before that information could be obtained one would need to know the following:
The amount of water present, the number and type of surfactants, the presence or absence of poorly biodegradable components, the number and type of additives to enhance stability in performance and the source of these components (ie whether naturally derived or synthetically produced). (In this context a surfactant is an ingredient which is active in removing dirt).
27 His conclusion was that many of the performance claims made on behalf of the products, required specialised expensive testing and specific knowledge of the component or the ingredient being used to deliver the performance. Information concerning the formulae and the manufacturing process was therefore required to test these performance claims.
28 Doctor Wynn-Hatton also sought to rebut the proposition fundamental to the plaintiffs' refusal to provide the formulae, ie that this information could be obtained by reverse engineering. The definition used by Dr Wynn-Hatton of "reverse engineering" was accepted by the parties:
"Reverse engineering refers to the process of taking a complete product and deconstructing it through various procedures and processes to its component parts, which can then be sourced separately and reconstructed to obtain a fully functional duplicate copy of the original product."
29 Doctor Wynn-Hatton was of the opinion that in most laundry products there will be a surfactant or a combination of surfactants with complex structures, as well as other additives, that contribute to either the stability or performance of the product. He accepted that testing would be able to analyse and identify major components in a product. Such testing would be expensive, difficult, time consuming and could never be guaranteed to be one hundred percent accurate.
30 In his reports Professor Pailthorpe said that it was not necessary to have a formula and method of manufacture of a product in order to make an accurate assessment of the product's likely performance. He illustrated this by reference to his own experience. When he was asked by a client to test the performance of a product he was never given the formula or method of manufacture.
31 In response Dr Wynn-Hatton said that defining performance of a product solely by reference to product evaluations achieved through specific wash tests, was unduly restrictive. It provided no information concerning environmental, cosmetic and therapeutic performance claims made in respect of the product. Those could only be assessed through an intimate knowledge of the composition. He said that the reason why Professor Pailthorpe was never given the formula and method of manufacture of a product was because his expertise was in comparative cleaning performance testing and he was providing only one piece of data in a total picture. Professor Pailthorpe's tests could show how a product cleaned but could not explain the reason for the performance or the attributes of the products that are measured by the tests. Without the formula there was no way of knowing how the products achieved their claimed superior performance.
32 Doctor Wynn-Hatton disagreed with Professor Pailthorpe and Dr Crank on the question of whether the preparation of a sample in 2008 could replicate a product that existed in 1999. It was the opinion of Dr Wynn-Hatton that such a process was not straightforward and could only be reliably achieved when the original formula was known and could be referred to and if all the original chemicals were still available.
33 Doctor Wynn-Hatton was of the opinion that it was necessary to obtain the formulae and method of manufacture of products in order to determine whether those products could contravene existing intellectual property rights such as patents. While that proposition might be correct in theory, under cross-examination it was clear that Dr Wynn-Hatton was not aware of any actual patents in Australia which might affect adversely the marketing of any of the products relied on by the company plaintiffs.
34 Doctor Wynn-Hatton was on stronger ground in his evidence as to the need for new products to withstand attack from competitors based on the Trade Practices Act and similar legislation. He said that if claims were made as to the content of a product, those claims had to be capable of substantiation. It was necessary to know the formula of a product to assess whether it could withstand such challenges.
35 The final point made by Dr Wynn-Hatton was that the disclosure of the formulae and method of manufacture of the products would significantly simplify the proceedings. He set out a table which indicated that the time and cost to perform tests to reverse engineer the products and to carry out other tests would cost tens of thousands of dollars and would take many months, if not years, to complete. He assessed the costs for all of the testing proposed by the plaintiff to be approximately $15,000 per product. This did not have regard to the testing of competitive products. While there was disagreement between Professor Pailthorpe and Dr Wynn-Hatton as to the precise costs involved, both agreed that the cost of the testing would be very high per product and very time consuming.
36 Dr Crank prepared reports and gave evidence on behalf of the company plaintiffs. He was also an industrial chemist with experience in analysing cleaning products. It was his opinion that it was not necessary to have the formula for a product in order to assess the product's performance. Such performance testing was a technical matter and simply involved subjecting a product to the appropriate tests either alone or compared with other established products.
37 It was his opinion that each performance characteristic identified by Dr Wynn-Hatton could be confirmed by an appropriate test. He accepted that a number of different tests would be required.
38 In relation to the particular matters referred to by Dr Wynn-Hatton he was of the opinion that there were tests which would identify the presence of active enzymes and that such tests would be able to identify the type of enzyme which was present. He agreed under cross-examination that such tests would not identify the quantity or percentage of enzyme in the products, although a reasonable level of accuracy could be achieved.
39 In relation to enzyme stability, it was Dr Crank's opinion that possessing the formula would not greatly assist in testing for this quality. This was because the problem of enzyme stability was a very complex one and that only tests over a period of time would give an accurate assessment of the stability of enzymes in a product.
40 In relation to environmental benefits Dr Crank was of the opinion that there were a number of tests which would establish such matters without it being necessary to have the formula. He identified those tests.
41 In relation to reverse engineering, Dr Crank was of the opinion that the constituent components of a product could be identified with a level of accuracy of up to ninety five percent. The surfactants could be identified, bleaches could be detected, alkaline salts could be identified and specific enzymes could be tested for by specific enzyme tests.
42 Under cross-examination the following answers were given by Dr Crank:
"Q. In order to determine whether it is commercially viable you don't need to know its constituent parts?
A. No. You can determine whether it is commercially viable by testing it to see whether it works and then by analysing it to see what it contains.
Q. In what order you do it nevertheless that is what you are seeking to ascertain and I am suggesting that its constituent parts or components is one of the elements that you are seeking to ascertain do you agree?
A. Yes eventually.
Q. Do you agree another element which needs to be known is the volume or quantity of each component or constituent part?
A. In order to accurately cost it, yes.
Q. Do you agree also that the cost of the product to produce including the cost of the chemicals and special or unique ingredients also needs to be known?
A. Yes. The cost of the chemicals has to be known yes." (T.71)
43 Professor Pailthorpe prepared reports and gave evidence in support of the company plaintiffs. He was a chartered textile technologist and had extensive experience in the evaluation of domestic laundry products.
44 It was his opinion that it was not necessary to have the formula and method of manufacture of the product in order to make an accurate assessment of the product's likely performance. A product's likely performance could be assessed by reference to a sample of the product without knowing its formula and method of manufacture. He thought that, providing all of the components that were used to formulate a product in 1999 were available today, it would be quite straightforward for a chemist to prepare a sample which replicated the product that existed in 1999.
45 As indicated, Professor Pailthorpe differed from Dr Wynn-Hatton in his assessment of whether the added performance achieved by the use of enzymes in a product could be assessed by testing. He thought that it could. He assessed the cost of such a test at $2,700.
46 As with Dr Crank, by reference to the particular qualities attributed to the products, he identified specific tests which could be carried out to substantiate or otherwise the presence of that quality. The cost of such testing varied significantly. For example to test the "softening qualities" of the product would cost $2,700 per test whereas to test the "anti-wrinkling" capacity would cost $92. To test stain blocking would cost $2,500 whereas to test brightening and the protection of coloured items would cost $100 per sample.
47 In relation to reverse engineering, however, Professor Pailthorpe largely agreed with Dr Wynn-Hatton.
"4.7 Reverse engineering.
I agree with PWH that an accurate qualitative and quantitative chemical analysis of a domestic laundry detergent would be nigh on impossible; even given today's sophisticated analysis techniques.
Such a detergent could contain a multitude of components, including detergents (conventional soaps, synthetic detergents etc), enzymes, water softeners, fabric softeners, alkali, anti-foaming agents, electrolytes, anti soil re-deposition agents, perfume and so on."
48 Under cross-examination Professor Pailthorpe agreed that in carrying out the various tests to which he had referred it would be necessary in some cases to know some components of the product that was being tested, eg the anti soil deposition agent, the name of the stain blocker, and the chemical names of the organic compounds employed in the formula. Nevertheless, Professor Pailthorpe adhered to his opinion that the entire formula was not required "as I have specified throughout my report, just certain compound names have to be disclosed, not the whole formula, not the method of manufacture but certain compounds would have to be disclosed to validate the claim." (T.85-86)
49 In answer to a series of propositions Professor Pailthorpe said:
"Q. Do you agree that in order to determine whether or not the product is going to be commercially viable you have to know certain things, I suggest one is what the product is?
A. Yes I agree.
Q. Two what its constituent parts or components comprise?
A. Yes.
Q. Three the volume or quantity of each component or constituent part?
A. Yes.
Q. Four, the cost of the product to produce including the cost of the chemicals and special or unique ingredients in the production?
A. Yes.
Q. Five, the performance characteristics of the products when used as intended?
A. Yes.
Q. Six, whether it can be legitimately or validly marketed, that is capable of withstanding challenges from regulators, opponents in the retail market, or under patents?
A. Yes." (T.88)
