17 Does Stena have an accrued right to have the opposition proceedings continue in accordance with the law as it stood at the time the notice of opposition was filed? Prior to the making of reg 5.3B Stena's defence of Danyard's opposition was not susceptible to the possibility that Danyard's sale of its business might result in the opposition continuing in the name of the purchaser. In my view that is not an accrued right. The regulation is a procedural facility enabling the purchaser of an opponent's business (including opposition proceedings) to seek an order that the proceedings continue as if the purchaser were the opponent. There is no alteration of Stena's rights. Its pursuit of a patent is currently being opposed by Danyard. If Austal replaces Danyard, Austal will become the opponent. The nature of the opposition will not change.
18 The next question is whether the right or interest on which Danyard relied to file its notice of opposition vested in Austal. I pose this question not because I am considering whether to make an order under reg 5.3B, but because, in fashioning an appropriate order under s 160(e), I am entitled to have regard to the fact that reg 5.3B exists, and empowers the Commissioner to make orders of the type I am asked to make under s 160(e). The right or interest on which Danyard relied was that from the early 1990s it marketed a Seajet hull design having many similarities with the hull shape disclosed in Stena's patent application. That was part of the business Danyard sold to Austal. That business passed to, or became the property of, Austal as a result of the sale agreement. It thereby vested in Austal.
19 Regulation 5.3B requires the new opponent to give notice to the Commissioner of the vesting in it of the opponent's right or interest and request the Commissioner to amend the notice of opposition. The Commissioner must give the parties to the opposition the opportunity to make representations concerning the proposed amendment. Obviously none of these steps has been taken in the precise manner contemplated by the regulation. But that does not matter. As I have said, I am not considering whether to make an order under reg 5.3B. The essential concern of the procedural requirements of the regulation is that the parties to the opposition have the opportunity to make submissions on the matter. In substance that has happened as a result of this motion. The Court has power under s 160(e) to make any order it thinks fit. In determining whether to make the substitution, the Court will consider whether the safeguards in the regulation have been satisfied. If, as in the present case, they have, it may, all other things being equal, make the order sought.
20 The final question is whether the Court should order that the notice of opposition be amended so as to show Austal as opponent. The facts I have summarised in pars 4 to 6 show a clear case for making such an order. Austal has a genuine and substantial commercial interest in the opposition and its prosecution. It has purchased the business of the opponent, together with the right to maintain the opposition. Even before the purchase Austal had a genuine commercial interest in the opposition. On the evidence now before me, whatever may be the position at trial, Austal entered the field of Stena's patent application before Stena, and continues to operate in the field. If granted, the patent has the potential to be a significant restriction on Austal's business. Austal has already taken part in the opposition through its alliance with Danyard, and has expended significant sums in costs associated with the opposition proceedings in the Patent Office and in the Court. Most of the costs have been incurred since its purchase of the business. All these costs would be wasted if Austal cannot be substituted as opponent before Danyard is dissolved.
21 Austal has explained its delay in causing Danyard to make this application. Until it discovered that Danyard was to be liquidated, Austal felt adequately protected by the sale agreement in which Danyard declared itself trustee for Austal of all the business assets, which included the opposition proceedings and the rights flowing therefrom. It was only in October 2001 that Austal became aware that Danyard was going to be liquidated in due course, and it became necessary for Austal to be substituted as opponent. Austal had disclosed to Stena its acquisition of Danyard's business about ten months earlier. In October 2001 it sought Stena's consent to the substitution, and provided it with the evidence showing its title to the opposition proceeding.
22 Danyard is entitled to an order under s 160(e) that Austal replace it as opponent. I will consider the precise form of the order in pars 29 and 30.
