He had spells at RSRE Malvern, London Headquarters and RAE Farnborough (RSRE and RAE are now part of QinetiQ). At RSRE and RAE he handled patenting of inventions in various technologies ranging across the fields of electronics, physics, engineering and chemistry. Whilst at RSRE, Derek worked on patenting of many of the UK’s basic liquid crystal inventions.

Derek subsequently worked for Royal Ordnance / BAe where he handled patenting and international licensing of defence technologies and defence contracting IPR. Following that he spent four years as Intellectual Property and Patents Manager at British Nuclear Fuels (4 years) managing patents and agreements work relating to the nuclear fuel cycle (which embraces many aspects of engineering, physics, chemistry and chemical engineering). Next, he worked for six years as Patents and Licensing Manager at English China Clays/Imerys handling in both UK and US patenting, patent infringement analysis and licensing work relating to minerals processing.
