Kate likes intellectual property. A lot. And, unlike her clients, she likes intellectual property disputes. Luckily for her clients, she likes resolving them even more. 


She also quite likes commercial conundrums – contracts and agreements like licences, franchises, manufacturing, settlement, confidentiality, publishing and sale and purchase agreements. Yes, she likes drafting contracts in her spare time.


And, she really likes copyright. Copyright often involves the creative sectors and Kate loves working with creatives helping them navigate the complexities of copyright law.  She can also help protect and defend brands and trade marks and sort out any patent disputes, as well as how to best commercialise patents, in New Zealand and Australia and the rest of the world as well.   

She uses her 15 years of experience in litigation and dispute resolution as well as her two law degrees and registered patent and trade mark attorney qualifications to do this. She also brings experience in having represented clients at more than 5o hearings before the Intellectual Property Office of New Zealand and in more than 20 hearings before the High Courts and beyond. Check out some of her cases under the Cases tab.  

Kate's two law degrees are from Victoria University of Wellington and she started with the Intellectual Property Office of New Zealand in 2000 before becoming a team leader and Assistant Commissioner in 2001. Kate joined Baldwins Intellectual Property in 2002 and became a partner and head of litigation and commercial in the Wellington office in 2010 before starting Catalyst Intellectual Property as a partner at the end of 2012.  Kate is also a registered patent attorney and registered trade mark attorney in New Zealand and Australia.

Kate brings a fresh approach to intellectual property law. Her advice is pragmatic and straight forward and that is why she has been named in World Trade Mark Review's 2013, 2014, 2015 2016, 2017, 2018 and 2019 listings for "The World’s Leading Trademark Professionals" and the only New Zealand woman to be named as an IP Star in the Top 250 Women in IP 2017 by Managing Intellectual Property.

When not eagerly anticipating her clients’ next innovation, she will be doing something dangerous like water skiing racing, mountain biking, snow skiing or else running or at the gym.
