Experience

Jason is a Division Head in our Technology and Engineering Group.

The majority of Jason's work is in advising SMEs and multinationals on their IP strategy, drafting, filing and prosecuting patent and design applications throughout the world and conducting freedom-to-operate projects.

Jason is a bilingual (French and English) European and Chartered UK Patent Attorney and UPC Representative. He also has Limited Recognition before the US Patent and Trade Mark Office. He was a European Trade Mark and Design Attorney before the UK left the EU.

He has a unique mix of skills and experience, from running an $8 million sales portfolio before entering the patent profession to developing a successful private practice and from successfully completing the USPTO Patent Bar exam to qualifying as a pilot (CAA Part-FCL IMC/IRR).

Jason's knowledge of both European and US patent systems, together with his commercial and sales experience gives Jason a unique advantage when advising both US and European clients.
