Environmental Technologies Inc (EPI) & Anor v Symphony Plastic Technologies Plc & Anor [2006] EWCA Civ 3 (26 January 2006)

Environmental Technologies Inc (EPI) & Anor v Symphony Plastic Technologies Plc & Anor [2006] EWCA Civ 3 (26 January 2006)

The trial judge's finding that Symphony did not analyse or copy EPI's DCP509 additive was not shown to be wrong. Technical, documentary, and expert evidence did not support an inference of copying. The burden of proof remained on EPI, and the evidence did not establish breach of contract or confidence. The claim for damages for non-return of 'know-how' was speculative and unsupported.
