Category 1
5 By category 1, VIP seeks all documents recording, referring or relating to the development of the pallet container disclosed in the Patent, including without limitation all documents recording, evidencing or referring to any trial, working or experimentation of the pallet container and all documents constituting or referring to any prior publically available material (including prior art products) that were referred to in the development of the pallet container. In essence, while the original categories 48 and 49 contained particular limitations as to date, versions and the like, this category seeks the whole of the research and development documents not just a subsection.
6 VIP argues that they are plainly relevant, in particular, to the question of inventive step.
7 VIP makes the point that the Patent is for a particular type of cage that has a type of welding which is said to 'relieve stresses'. VIP wants to explore the extent to which it might have been within common general knowledge that there were problems with these cages. VIP want to ascertain whether customers complained to Schutz about the problems with the cages which, VIP suggest, would say that the problem was an 'obvious one'.
8 In Wellcome Foundation Ltd v VR Laboratories (Aust) Pty Ltd (1981) 148 CLR 262, the High Court affirmed a decision of the Full Federal Court (Wellcome Foundation Ltd v VR Laboratories (Aust) Pty Ltd (1980) 142 FLR 266) on this topic. Wellcome had sued in the Supreme Court of New South Wales for infringement of a patent in relation to 'improvements in or relating to injectable therapeutic compositions'. VR denied infringement and counterclaimed for a declaration of invalidity of the patent on various grounds including that the invention was obvious and did not involve an inventive step, having regard to what was known or used in Australia on or before the priority date of the claim. To support that defence and counterclaim, VR sought further and better discovery of the following classes of documents:
(a) documents relating to research and development and experimental work on a claimed invention both before and after the priority date of the subject of the subject letters patent;
(b) documents relating to the provisional application for the patent and documents relating to the application for the complete patent, as the case may be, both in the United Kingdom and in Australia and elsewhere insofar as they contained matters relevant to (a) and, in any event, all such documents for the United Kingdom and Australia; and
(c) documents relating to infringement, revocation or opposition proceedings in any country of the world where a corresponding patent has issued or been applied for insofar as they contained admissions by or on behalf of Wellcome and relevant to (a).
9 At first instance, the primary judge made an order for further and better discovery in terms of para (a) and para (b) but deleted from the description of the documents in para (b) the words 'and elsewhere' and the words 'and in any event all such documents for United Kingdom and Australia'. Discovery was refused in relation to the documents described in (c). Wellcome appealed to the Full Federal Court (Bowen CJ, Franki and Deane JJ). The appeal was dismissed by Aickin J in the High Court, with whom Gibbs ACJ, Stephen, Mason and Wilson JJ concurred, affirming the decision under appeal saying (at 287-288):
In the result therefore I have concluded that evidence of research and experiments (if any) of a patentee leading up to his claimed invention is generally admissible though not always likely to be helpful. The fact that in a particular case there may not have been any research or experiment involved in the making of an invention does not require the conclusion that evidence relating to research and experiments, where they took place, will not be admissible.
So far as discovery of documents is concerned the test is wider than the test of admissibility as the statement of Windeyer J. in Temmler's Case, which I have quoted above, demonstrates. It may be that in many cases documents recording such research and experiment could properly be said to relate solely to the inventor's own case but that ground for refusing discovery is no longer available in New South Wales, having been abolished in 1976 by the insertion of r. 6a in Pt 23 of the Supreme Court Rules 1970 (N.S.W.).
The cases to which I have referred appear to show that some discovery in respect of the work done by a patentee in arriving at his invention has been given as a matter of course and that the disputes have been as to the extent of discovery. Since evidence of such work may in some cases be relevant to the issue of obviousness it must follow that discovery should generally be given, even if only on the basis that the documents discovered may suggest a line of enquiry worth investigation.
10 In the last passage cited above, his Honour makes the point that 'some' discovery of this character would be appropriate. His Honour then ultimately makes the point that this would be so even if only the documents may suggest a line of inquiry worth investigation. This reasoning was consistent with the Peruvian Guano test (Compagnie Financiere et Commerciale du Pacifique v Peruvian Guano Company (1882) 52 LJQB 181). That position has significantly changed. The Rules of this Court, consistent with those changes, reflect a significantly less broad ranging ambit of discovery.
11 While the nature of the discovery pursued by VIP may be relevant, it does not follow that the extensive range of discovery which might once have been permitted will now be appropriate. The observations of the High Court in Wellcome do not constitute an erosion of the Court's general discretion to be applied in permitting discovery, especially in more modern times when electronic reproduction has massively magnified the burden compared with the benefit.
12 The following observation applies to the approach I adopt for most of the categories of discovery sought by Schutz and VIP. I consider that most of the categories are so broad as to be oppressive on their face.
13 The discretion as to the necessity for and the extent of the discovery will turn on the particular case. In my view, a stand must be taken against insistence of production of every last note of possible tangential relevance. A number of authorities have recognised that discovery can be an intrusive and oppressive tool, particularly in the hands of a business or trade rival: see Austal Ships Pty Ltd v Incat Australia Pty Ltd [2009] FCA 368 (at [129], [133]-[135], [137]-[139] and [150]):
129 It must be recalled that discovery is an invasive procedure by which production of a party's documents or other non-public records may be compelled. That compulsion is one of the reasons that the extent to which discovery must be given is limited.

133 One of the fundamental questions arising in the extent of discovery which is sought by this application is whether or not it constitutes a fishing expedition. In Associated Dominions Assurance Society Pty Ltd v John Fairfax & Sons Pty Ltd (1955) 72 WN(NSW) 250 at 254, Owen J described 'fishing' as arising when:
... a person who has no evidence that fish of a particular kind are in a pool desires to be at liberty to drag it for the purpose of finding out whether there are any there or not.
134 Similarly, if the attempt to gain information is speculative in nature it will be 'fishing': Melbourne Home of Ford Pty Ltd v Trade Practices Commission (1979) 36 FLR 450; WA Pines Pty Ltd v Bannerman (1980) 41 FLR 175. The question is whether the applicant has shown a good case, proof of which is likely to be aided by discovery.
135 In Trade Practices Commission v CC (New South Wales) Pty Limited (1995) 58 FCR 426, Lindgren J dealt with the balance between a fishing expedition and giving discovery by a party who has the only knowledge on which the claim is based. In that case, the applicant had already supplied reasonably detailed particulars and had the benefit of transcripts from compulsory examinations. His Honour said at 439:
4. Apparently the Commission does not know what was said at either the Meeting or at the alleged prior meetings. I do not think, however, that this means that it does not know whether it has a case. The pleading and the particulars supplied are reasonably detailed. Moreover, there is some evidence in the transcripts of the evidence given by individuals to the Commission of the existence of a case of the kind pleaded. In my view, the Commission's application is not a "fishing expedition".
5. The respondents submit that the Commission should be directed to "supply particulars by putting on its affidavit evidence" before the discovery issue is decided. I do not agree. A well accepted situation which the court often exercises its discretion by ordering discovery before particulars are supplied is that in which the party which seeks particulars and resists discovery is alone in possession of the relevant documents: Millar v Harper (1888) 38 Ch D 110 at 112; Egg & Egg Pulp Marketing Board v K H Korp Tocumal Trading Co Pty Ltd [1963] VR 378; L Grollo & Co Pty Ltd v Nu-Statt Decorating Pty Ltd (1978) 34 FLR 81 at 90-91; Halsbury's Laws of England (4th ed, 1975), Vol 13, par 28; BC Cairns, Australian Civil Procedure (3rd ed, 1992), p 348. In my view, I should exercise my discretion accordingly in the present case. (emphasis added)
…
137 It is well established that generally a discovery affidavit is conclusive on the question of whether a party has or has had in its possession, custody or control of any relevant documents other than those discovered: Betts Group Pty Ltd v Paul's Retail Pty Ltd [2007] FCA 1983 at [15]; Mulley v Manifold (1959) 103 CLR 341.
138 Under O 15 r 8, however, there is a procedure under which particular discovery may be sought where a party is dissatisfied with the extent of the discovery made by the opposing party. The Court may exercise its discretion under O 15 r 8 where it is clear that there has been a defect in compliance with an earlier order for discovery if it appears, for example, that a party has excluded documents under a misconception of the case as Austal argues is the position here: Mulley 103 CLR 341 at 343.
139 However, in Slick v Westpac Banking Corporation (No 2) [2006] FCA 1712 at [43], particular discovery was refused on the basis that 'the theoretical possibility that something might turn up [was] well and truly outweighed by the cost and burden to Westpac' (see also Betts [2007] FCA 1983).
…
150 As observed by Tamberlin J in KGL Health Pty Ltd v Mechtler [2008] FCA 273 at [9], if classes of documents are sought, they should be framed so as not to be too wide and need to be stated with sufficient specificity.
14 Schutz contends that they have already discovered everything necessary in category 1 as they fall within the original categories 48 and 49 in which discovery has already been given. Given that the records are 15 years old, the Court should infer that any records not discovered by Schutz are records that were once in their possession, custody and power and have subsequently been lost or destroyed. Schutz complains that the category is not limited in time and is so broad as to be oppressive. The scope of category 1 would require Schutz to conduct searches for, translate from German to English (at great expense and causing significant delay) and discovery of potentially thousands of documents in a very wide category.
15 I consider that this category is too broad. I do not propose ordering discovery in terms of category 1 but I would review the position if the category of documents were substantially narrowed.
