In cases of claimed copyright infringement, it is not the function of the expert to decide the question of substantiality. In cases of simple visual comparison the court can and should do the visual comparison for itself. A distinction between the ‘idea’ of the program and its ‘expression’ is not a distinction known to English law.
Jacob J said: ‘The true position is that where an ‘idea’ is sufficiently general, then even if an original work embodies it, the mere taking of that idea will not infringe. But if the ‘idea’ is detailed, then there may be infringement. It is a question of degree. The same applies whether the work is functional or not, and whether visual or literary. In the latter field the taking of a plot (i.e. the ‘idea’) of a novel or play can certainly infringe-if that plot is a substantial part of the copyright work. As Judge Learned Hand said (speaking of the distinction between ‘idea’ and ‘expression’): Nobody has ever been able to fix that boundary and nobody ever can.”
