The expert witnesses
The Claimants called Professor Bernard Thorens (biology/pharmacology) and Dr Paul Edwards (medicinal chemistry). AstraZeneca called Professor Clifford Bailey (biology/pharmacology) and Professor Barry Potter (medicinal chemistry). The judge found that all four witnesses had done their best to assist the court and that the areas of dispute between them on matters which were for expert evidence were fairly limited.
