Clare is listed in Doyle's Guide to Leading Victorian Intellectual Property Barristers (2023) and in Doyle’s Leading Intellectual Property Junior Counsel – Australia (2022) as a pre-eminent junior counsel.

She has been listed in Chambers Intellectual Property: The Bar as a Band 1 practitioner since 2020.  Her review reads:

“Operating across the IP spectrum, Clare Cunliffe is particularly well known for her "encyclopedic knowledge of patent law and patent decisions in Australia and beyond, and her ability to bring that knowledge to bear in cases." This makes her "a first choice for large, complex patent infringement and validity proceedings," it being further noted that "leading IP senior counsel tend to choose her as their junior." More than one interviewee places her in the front rank of junior counsel practising at the IP Bar.”

 and in the Legal 500 Asia-Pacific (2020) as a Leading Junior.  Her review reads:

Her knowledge of patent law and her ability to grasp complex technology sets her apart in this field. Clare is a leading junior in patent, trade mark, copyright, consumer law and competition matters.”
