Patents - Life Sciences

• Advised and acted for Wyeth in one of the largest and most complex life sciences patent litigations ever in Australia, involving three separate proceedings against eight separate parties (including the Commonwealth of Australia) in respect of their claims on undertakings as to damages ordered in return for interlocutory injunctions preventing the launch of generic extended release venlafaxine products. These three cases, which involved a six week trial, were the first cases in Australia to address claims on undertakings as to damages in pharmaceutical patent litigation by generic pharmaceutical companies, their suppliers and the Commonwealth of Australia.
• Advising and acting for Pfizer in Australia’s first biologic / biosimilar patent dispute, as well as several other patent disputes, involving six adverse parties, relating to Pfizer’s patents covering the process for producing etanercept, the active ingredient in Pfizer's blockbuster biological medicine Enbrel®. We have already achieved success in this ongoing matter before Australia’s highest court.

This ongoing case has already established new law in several areas, including in relation to patent amendment. We worked as part of a global team, managing and coordinating strategy across numerous jurisdictions.
• Advising and acting for Pfizer and Pharmacia in patent infringement and revocation proceedings in relation to Pharmacia’s patent covering the parecoxib reconstitutable powder injectable formulation for Pfizer's Dynastat® pain medicine.

• Advised and acted for an American global pharmaceutical company in relation to patent issues relating to a number of the company's products. This included acting for the company in multiple proceedings in Australia, and co-ordinating proceedings in other Asia-Pacific jurisdictions, as part of a global team involved in multi-jurisdictional patent infringement and revocation proceedings with respect to a family of patents relating to the company's successful anti-cancer treatment product. In the main Australian proceedings, the company successfully resisted a challenge to the patent term extension of one of the patents-in-suit, successfully amended the claims of that patent in the course of litigation and successfully obtained an interlocutory (preliminary) injunction enjoining the marketing of two generic competitors' products. The proceedings established an important set of guiding principles in Australia for determining when an interlocutory injunction will be granted in pharmaceutical patent infringement cases.
