University of Western Australia v Gray (No 20)

The University of Western Australia initiated legal proceedings against Dr Bruce Gray, Dr Yan Chen, and Sirtex Medical Ltd. The dispute centred on the alleged infringement of patent rights by Dr Gray and Sirtex, with Dr Chen being accused of breaching fiduciary duties and engaging in misleading conduct. The matter was heard in the Supreme Court of Western Australia.

The legal issues that required resolution included determining whether Dr Gray and Sirtex had infringed the patents held by the University of Western Australia, and whether Dr Chen had violated his fiduciary duties or engaged in misleading conduct. The court had to examine the validity and scope of the University’s patents, the nature of the alleged infringements, and the conduct of Dr Chen in relation to the University and Sirtex.

The court found that Dr Gray and Sirtex did not infringe the University's patents, as the claimed inventions were not identical to those patented by the University. The court further ruled that Dr Chen did not breach any fiduciary duties or engage in misleading conduct. Consequently, the claims against Dr Gray and Sirtex were dismissed, and Dr Chen was cleared of all charges. The court also dismissed the cross-claims filed by Dr Gray against Dr Chen, with no order for costs made in relation to these claims.

The final orders of the court dismissed the University's application, ordered the University to pay the costs of Dr Gray, Dr Chen, and Sirtex, and dismissed the cross-claims against Dr Gray and Dr Chen. The cross-claim by Sirtex against Dr Gray was stood over for a future directions hearing to assess damages related to the alleged breaches by Dr Chen. The court scheduled a directions hearing to further address the assessment of damages.
