Callum Wardle B.Eng, CPA, EPA


Callum is a patent attorney in our Electronics, Computing & Physics group.

Callum’s technological specialism is in electronics, though his broader engineering experience has enabled him to work in other related fields, most notably aerospace components and systems.

Callum’s wide ranging technological and engineering interests have equipped him with the ability to appreciate quickly the fundamental concepts behind new inventions. An easy going nature and common sense approach helps Callum quickly form a strong rapport with his clients.

Education & background

Callum gained a degree in Electrical & Electronic Engineering at Nottingham University before beginning his training as a patent attorney with a London firm in 1997. He joined Withers & Rogers in 2001 and became a partner in 2005. In March 2023, he was registered as a representative before the new Unified Patent Court, one of the first European patent attorneys to be entered on the list of UPC representatives.

On a personal note...

Callum’s main hobby is music, playing the trumpet in a local concert band. His greatest claim to fame is performing on stage at the Festival Hall in London. Callum is also a canal enthusiast, being an active member of his local canal restoration trust and owning his own narrowboat. Both activities provide a relaxing counterpoint to Callum’s professional life!
