Pansea Ltd had operated an electrical store in Clonmel under the DID name since October 2011.
The outlet at the Poppyfield Retail Park closed last week when the franchise came to an end following a breakdown in negotiations where DID had proposed buying the Clonmel business for €1.7 million.
Patrick Leonard, Senior Counsel for Pansea Ltd, claimed representatives from the retail chain turned up at the store last Thursday while the outlet was closed for rebranding.
He said DID began intercepting business destined for his clients.
Negotiations between both sides failed to resolve the issue following which Pansea sought ex-parte injunctions or undertakings.
Mr Justice Paul Gilligan gave Mr Leonard permission to serve proceedings at short notice on DID.
