Claire joined the Davies Collison Cave chemistry/pharmaceutical group as an Associate in 2020. Her practice involves assisting clients to obtain patent protection for innovations in the chemical and pharmaceutical fields, including securing extensions of patent term for pharmaceutical patents. Claire also conducts patent oppositions and procedural hearings before the Patent Office, provides advice in relation to patent strategy, validity and infringement, and assists in patent litigation.

Claire began her scientific career studying a Bachelor of Technology (Forensic & Analytical Chemistry) and a Bachelor of Science with first class honours from Flinders University, for which she was awarded a University Medal. She then completed a Ph.D. for research on the total synthesis and structural elucidation of complex biologically active natural products, also at Flinders University. Claire’s research in synthetic organic chemistry continued at the Bio21 Molecular Science and Biotechnology Institute of the University of Melbourne, before she took up a postdoctoral fellowship at Vanderbilt University in the United States. Her postdoctoral research focused primarily on hit-to-lead optimisation of small molecule inhibitors of protein-protein interactions in highly validated cancer targets, as part of a multidisciplinary team in collaboration with the National Cancer Institute.

In 2013, Claire commenced her training as a patent attorney at a large patent firm in Sydney, and gained further experience in contentious patent matters at a top-tier commercial law firm. She is an active member of the Institute of Patent & Trade Mark Attorneys (IPTA), the peak professional body for patent and trade mark attorneys in Australia, and co-convenes the Young IPTA (YIPTA) committee. She is also a member of the Future Directions and Conference committees, and a former member of the Legislation committee. Claire has been awarded the John McLaren Emmerson QC Essay Prize (formerly the Intellectual Property Society of Australia and New Zealand (IPSANZ) Prize) twice, once in 2014 for her essay on the patentability of isolated nucleic acids in Australia and again in 2019 for her essay on Australia’s controversial ‘best method’ requirement. She was also awarded second prize in 2017 for her essay exploring whether Swiss-style claims should be eligible for patent term extension.
