Abuse of Process
8 The respondents identified the substance of their abuse of process argument and, therefore, their proposed separate question as being set out in paragraphs 76, 77 and 78 of their Amended Defence. Those paragraphs are in the following terms:
76 By reason of the conduct of the Applicants, in the circumstances as above set out, the commencement by the Applicants and any continuation of these patent infringement proceedings by the Applicants against the Respondents based on the same core orientation tool which twice has been the subject of separate and earlier patent infringement proceedings in this Court was and is an abuse of process as it would involve:-
(a) substantive patent infringement issues and considerations for the Court that could have, and should have, been raised by the Applicants in those earlier proceedings;
(b) wasted Court time and wasted public resources in litigating for the third time patent infringement issues, and a defence to such issues including by way of a challenge to the validity of the Patent that could have, and should have, been relied upon by the Applicants in those earlier proceedings;
(c) substantial unfairness, injustice and prejudice to the Respondents by way of substantially increased legal costs and business inconvenience associated with defending a third, separate consecutive patent infringement proceeding in respect of the same core orientation tool of the First Respondent which had been the subject of those earlier proceedings; and
(d) as to the Fourth Respondent, would involve substantial unfairness, injustice and prejudice arising from matters now alleged against it which could have, and should have, been raised in proceeding NSD 2082 of 2011.
77. In the premises of the foregoing, the commencement and continuation of these further proceedings of patent infringement by the Applicants against the Respondents was, and is, an abuse of process so that the said proceedings should be permanently stayed or dismissed.
78. Further or alternatively to paragraph 77 hereof and in the premises of the foregoing:
(a) the Applicants have failed in their obligations to the Court arising under s37N of the Federal Court of Australia Act 1976 (Cth);
(b) the maintenance of these proceedings is in breach of s37M of the Federal Court of Australia Act 1976 (Cth); and
(c) the proceedings should be permanently stayed or dismissed
9 I do not think that the respondents have established a sufficient basis for a separate question. My reasons are as follows:
(1) The abuse of process argument seems to involve a mixed question of fact and law. The precise evidence which may be called is difficult to identify at this stage, and the likely length of a hearing with respect to the abuse of process argument is unclear. There is a reasonable prospect there will be not insignificant evidence called with respect to the argument. The extent to which the judge determining the abuse of process argument could then go on and hear the remaining issues is unclear.
(2) There is a good deal of force in the applicants' submission that no draft of the proposed separate question has been provided to the Court and to the applicants and that that indicates that a concise question appropriate for determination as a separate question cannot be formulated. In other words, although it is no doubt possible to formulate questions about issues in a proceeding, the more difficult it is to formulate the questions and identify the way in which they link to each other, the greater the probability that it is not appropriate to hear and determine those questions separately.
(3) The point that the respondents wish to raise by way of their abuse of process argument appears to be a novel one. They accept that what the applicants have done is "entirely permissible" under the Patents Act 1990 (Cth). However, they claim that "the abuse arises when divided out patents are then used as a basis for litigation in this Court". They claim that the difficulties with what the applicants have done is "a worldwide problem, this issue of divisionals". They claim that it raises "a serious policy issue". It seems to me that the more novel the issue sought to be raised as a separate question, the more likely it is that there may be appeals which would have the potential to delay the overall resolution of the proceeding. I think that is undesirable.
10 I refuse the respondents' application for a stay and for the hearing and determination of a separate question.
I certify that the preceding ten (10) numbered paragraphs are a true copy of the Reasons for Judgment herein of the Honourable Justice Besanko.
