Callum Judd
Callum is an associate in AJ Park’s Auckland engineering and ICT team.


Callum’s role includes preparing, filing and prosecuting patent applications in Australia, New Zealand, and internationally. He is also experienced in a variety of patent searching, including patentability and freedom to operate searches, as well as considering infringement positions.


With a degree in Chemical and Materials Engineering, Callum understands how mechanical inventions or processes operate, as well as the relationships between the components and their environment.

Callum became interested in intellectual property (IP) early while at university. He spent the summer and final year of his degree working at another New Zealand IP firm, before joining Baldwins (now AJ Park) in 2019.

Building client relationships is key to achieve trust and clear communication between both parties to ensure an efficient and clear path to the client’s goals.

Beyond Work

In his spare time, Callum enjoys watching and playing various sports (some more socially than others) and is always open to discuss these at length.
