- The Full Federal Court has unanimously confirmed that isolated nucleic acids, either DNA or RNA, are patentable in Australia
- The decision is in contrast to the recent decision of the US Supreme Court, which held a naturally occurring DNA segment is not patentable because it has been isolated
- The decision does not change the law in Australia but will be welcomed by the biotechnology industry for the certainty it provides
In D’Arcy v Myriad Genetics Inc  FCAFC 115, a specially constituted five-member bench of the Full Court of the Federal Court of Australia held that isolated nucleic acids, either DNA (eg genomic DNA or cDNA) or RNA, are patentable in Australia. In doing so, the Court unanimously upheld the 2013 decision of Justice Nicholas at first instance in Cancer Voices Australia v Myriad Genetics Inc  FCA 65.
The patent at issue is directed to mutations in the breast cancer gene BRCA1, which is associated with an increased risk of breast cancer, and a diagnostic test to detect the presence of the BRCA1 gene. Only the claims directed to nucleic acids were considered. The case has attracted significant media attention due to the policy, social and moral issues at play.
