*AFD Software Ltd v ZIP Address Ltd

Copyright – Infringement. The first claimant company, AFD, supplied database services to the defendant, DCML. After some years, AFD recalculated its fees and demanded a much higher sum from DCML. It brought proceedings, seeking to recover that sum. The Chancery Division held that DCML's representative had not misled AFD's representative, and that DCML's defence of estoppel was made out, so that AFD's claim failed.
