The witnesses
13.Charles Shaw is a former Managing Director of Quinn. He was Quinn’s expert at the trial. Between 1993 and his retirement in 2014 he held managerial roles in the plastics industry, both in this country and in Spain, becoming Managing Director of Quinn in 2012. Mr Shaw gave clear answers to all question put to him. He was a good witness. He had less direct design experience than the other experts who gave evidence, his views having been formed very largely from a managerial perspective. He was therefore further from the notional skilled person than the other two but I do not believe that this undermined the credibility of his evidence on technical matters. 14.Mark Strachan gave expert evidence for Linpac. Since Mr Strachan graduated in 1986 he has worked in the plastics industry in the UK and abroad, with experience in plastics thermoforming, extrusion and injection moulding, this experience including the design of new packaging products. Mr Strachan was a good witness although not always completely clear. 15.Thomas Lynggaard is a Senior Materials Scientist at Faerch in Denmark and is one of the two named inventors of the Faerch patent. Mr Lynggaard is a specialist in the design and manufacture of plastic packaging for food and has worked for Faerch since 1999. Mr Lynggaard was also a good witness, giving clear and straightforward answers.
