Jeff is European Patent Attorney, Chartered UK Patent Attorney and Australian Patent Attorney, with over 20 years’ experience in the patent profession. His experience spans a broad range of technologies, ranging from electronics, image processing, telecommunications, printer technology and medical devices to automotive engineering, consumer goods packaging, gas turbine engineering and mining technology. 

Jeff’s current focus is patent drafting and prosecution, along with freedom-to-operate and validity opinion work.  Jeff has a keen interest in invention capture and working with inventors to get to the heart of inventive subject matter. His extensive experience before the EPO (including oral proceedings) means he offers a high prosecution success rate.

Jeff loves working with early stage businesses and SMEs. Unfortunately, many growing companies leave it too late to sort out their IP. Early advice needn’t be expensive but can make a huge difference to growth, survival rates and, ultimately, valuation where an exit is intended. Jeff’s experience with taking a start-up with no paid employees through to a successful trade sale following several fund-raising rounds leaves him with a unique understanding of the IP pressures facing young businesses.

Career history

Jeff has worked in the UK and Australia, both in private practice for British and Australian firms, as well as in-house at a major inkjet printer research company. 

He was the first full-time employee and executive director of a start-up patent administration company that he helped build towards acquisition by an international patent services company. This experience gave Jeff a fantastic insight into the pressures faced by early stage businesses. 

Jeff recently provided litigation support to a US-based patentee, working with solicitors, barristers, expert witnesses and the patentee over three years in relation to several successful high-profile British and German court cases involving standards-essential telecommunications patents.
