Principal & National Practice Group Leader - Chemical

With over 24 years’ experience as a registered patent attorney, I have vast experience in drafting and prosecuting patent applications.

Having acted in patent litigation and patent opposition proceedings before the Federal Court of Australia and Australian Patents Office, I practise all aspects of patent attorney work – from drafting specifications for new inventions to enforcement work, as well as providing patent validity and infringement opinions.

I specialise in the field of chemistry which spans across the pharmaceuticals, biotechnology, food technology and mineral processing industries. My clients range across the whole spectrum – I act for large multinational clients, small local clients, universities and start ups.

I graduated from the University of Western Australia with first class honours and a PhD on the synthesis of macrocyclic compounds and their application in the solvent extraction of lanthanides and actinides. A number of publications in international journals resulted from this work. I then completed a postdoctoral position at the University of Liverpool in the United Kingdom researching small molecule syntheses in supercritical fluids.

I enjoy the hands on element of working at Wrays. Attorneys get exposure to clients across a whole range of sectors and, being a very flat organisation, clients get access to everyone.
