Commonwealth can sue on the undertaking as to damages
The Full Court (Dowsett, Kenny and Nicholas JJ) has upheld the Commonwealth’s power to sue for damages on the undertaking as to damages given by Sanofi and Wyeth when obtaining interlocutory injunctions against generic suppliers.
Sanofi sued Apotex (then called GenRX) for patent infringement when the latter sought to registration in the Therapeutic Goods Register of drug containing clopidogrel. Sanofi obtained an interlocutory injunction preventing the listing and sale of Apotex’ product, on terms of the “usual undertaking as to damages”. Thus, as a condition of obtaining the interlocutory relief, Sanofi undertook to the court:
(a) to submit to such order (if any) as the Court may consider to be just for the payment of compensation, to be assessed by the Court or as it may direct, to any person, whether or not a party, adversely affected by the operation of the interlocutory order or undertaking or any continuation (with or without variation) thereof; and
(b) to pay the compensation referred to in (a) to the person there referred to. (emphasis supplied)
After the trial judge found Sanofi’s patent valid and infringed, the Full Court on appeal held that the patent was invalid. Ultimately, the High Court refused special leave.[1]
The Commonwealth, which was not a party to either the Sanofi or Wyeth proceedings is now claiming compensation from Sanofi and Wyeth under the “undertaking as to damages”. In broad terms, it says it suffered losses because the price it paid under the Pharmaceutical Benefits Scheme was higher than it would have been if the generic parties had not been prevented from listing and selling their products by the interlocutory injunctions.
Sanofi and Wyeth argued that sections 26B, 26C, 26D of the Therapeutic Goods Act[2] precluded the Commonwealth from claiming under the usual undertaking as to damages. The Full Court held, however, that these provisions were ancillary or additional to the Court’s powers under the undertaking. They did not provide an exhaustive code which excluded the operation of the undertaking.
Dowsett J delivered a concurring judgment, suggesting at [20] that some restriction on the scope of the usual undertaking should have been sought and then questioning, if such a restriction had been sought, whether it would have been appropriate to grant the interlocutory injunction:
…. As the Commonwealth was not a party to the proceedings in which the undertakings were given, they were presumably not extracted at its request. I infer that the Court extracted the undertakings. It is not suggested that it lacked the power to do so in order to protect the interests of identified or unidentified third parties. In submitting that the Commonwealth may not recover other than pursuant to s 26C, the Sanofi and Wyeth parties effectively seek to resile from their undertakings. It may be simply too late for them to do so. Any limitations upon the undertakings ought to have been sought at the time at which they were given. The Court would then have had to consider whether such limited undertakings were sufficient to justify the grant of the interlocutory injunctions. The Commonwealth has not put its case in that way. However, in any event, I see no basis for limiting the Commonwealth’s right to seek to enforce the undertakings to the extent that it benefits under them.
If only the regime under sections 26B, 26C, 26D had been available, it looks like Sanofi’s and Wyeth’s exposure would have been limited to situations where they had given false or misleading certificates or did not have “reasonable prospects of success”.[3]
Commonwealth of Australia v Sanofi (formerly Sanofi-Aventis) [2015] FCAFC 172
- Similarly, in the Wyeth proceedings an interlocutory injunction was granted on the usual undertaking as to damages, but the patent was ultimately found to be invalid. ?
- These provisions were introduced as part of the package implementing the Australia – United States Free Trade Agreement relating particularly to the 5 year data exclusivity for pharmaceutical test data. ?
- Defined in s 26C(4) as “(4) For the purpose of paragraph (3)(b), proceedings have reasonable prospects of success if: (a) the second person had reasonable grounds in all the circumstances known to the second person, or which ought reasonably to have been known to the second person (in addition to the fact of grant of the patent), for believing that he or she would be entitled to be granted final relief by the court against the person referred to in paragraph (1)(a) for infringement by that person of the patent; and (b) the second person had reasonable grounds in all the circumstances known to the second person, or which ought reasonably to have been known to the second person (in addition to the fact of grant of the patent), for believing that each of the claims, in respect of which infringement is alleged, is valid; and
(c) the proceedings are not otherwise vexatious or unreasonably pursued.” ?
