News Datacom Ltd. v. Lyons [1994] IEHC 1; [1994] 1 ILRM 450 (20th January, 1994)

News Datacom Ltd. v. Lyons [1994] IEHC 1; [1994] 1 ILRM 450 (20th January, 1994)

The plaintiffs failed to provide direct or inferential evidence of copying of their software or algorithm, relying solely on functional similarity and speculative expert opinion. The court held that functional similarity is insufficient to infer copying without evidence of similarities in the actual software or algorithm. Therefore, the plaintiffs did not raise a fair question to be tried, and the interlocutory injunction was refused.
