Product Management Group (PMG) has lost its appeal from Middleton J’s finding that it infringed Blue Gentian’s innovation patents for a self extending/collapsing garden hose.

The appeal seems like a fairly straightforward application of construction principles and demonstrates, yet again, how slender an innovation need be to secure a monopoly for eight years.

There may, however, be a question for the future whether or not the “substantial contribution” to the working of the “invention” required by s 7(4) must be a positive contribution to the working of the invention.[1]

An interesting point is the Order Middleton J made for delivery up. His Honour did not just require delivery up of PMG’s unsold stock and componentry. In addition, by paragraph 3(c), his Honour ordered that PMG should contact the customers to which it hold sold the infringing products, offer them a refund and request that they return the products to PMG.

Nicholas J considered this travelled well beyond the purpose of an order for delivery up. His Honour considered that purpose was to relieve the infringer from the “temptation” of further infringing and so, in that sense, was in aid of the injunction. Nicholas J considered that an order requiring a party to try and retrieve property to which it no longer had any legal title could not fairly be described as in aid of delivery up and so would have set aside that part of the Order.

In circumstances where the Court had not been favoured with any oral submissions and only brief mention in written submissions, however, Kenny and Beach JJ were not persuaded that his Honour’s discretion miscarried and their Honours would let it stand in this case. However, they warned:

But our rejection of this ground should not be taken as any endorsement of this form of order for the future. We doubt that such an order would ordinarily be appropriate. We do not need to comment further.

This may pose an interesting dilemma for “convicted” infringers: object to such an order or, as the purchasers’ use of an infringing product would itself be an infringement, risk having the successful plaintiff require discovery and then suing the individual customers for infringement too.[2]

  1. Compare Kenny and Beach JJ at [178] to Nicholas J at [284].  ?
  2. On the approach taken vy Yates J in Winnebago (No 4). Of course, the plaintiff might not be willing to pursue individual purchasers of garden hoses, but what about Bunnings and the other hardware chains?  ?
