“A Moron in a Hurry” is a formalized legal term used in the UK and Canada and the US. It was first established in a 1978 UK court case : The Morning Star Cooperative Society v Express Newspapers Limited, and subsequently reaffirmed by Alfred Thompson “Tom” Denning, OM, PC, DL (Baron Denning,) [pictured] in the case of Newsweek Inc. v British Broadcasting Corp. [1979] R.P.C. 441
The phrase is typically used in cases of copyright infringement – examining the question of whether a moron in a hurry would spot the difference (or similarity) of two products or services.
