Paul Kallenbach
Partner, Melbourne
I have wide-ranging expertise which spans strategic and global outsourcing, procurement and supply, technology contracting, licensing and commercialisation, ecommerce, privacy and content regulation, and intellectual property.

My practice traverses multiple public and private industry sectors including financial services, mining and resources, government, health, pharmaceutical and biotechnology, ecommerce and telecommunications.

I bring a heightened understanding and sharp commercial focus to technology transactions, having established and managed a software start-up.

I am a frequent commentator, platform speaker, author and guest lecturer on a wide range of legal and commercial issues across the technology sphere.
