4. Case study of current best-practise Eco-Innovation: the development of energy
efficient lighting
In this part of the study the authors wanted to study a collection of best available
environmentally designed products which we have called ‘Eco-innovation exemplars’. The
sunbject chosen was energy efficient lighting. Without any sophisticated patent searching
software the authors needed to study the development of energy efficient lighting to be able
to select the most relevant products and select a limited time span over which to study their
patents.
