 A divergence between, on the one hand, decisions T 163/85 and T 190/94, according to which a technical effect on a physical entity in the real world is required (to escape the exclusion under Article 52(2)(c) and (3)), and, on the other hand, T 125/01 and T 424/03, according to which the technical effects can be essentially confined to the respective computer programs, is cited as justifying this question.A divergence between decisions considering that a programmer's activity, i.e.writing computer programs, falls within the exclusions of Article 52(2)(c) (T 833/91, T 204/93, and T 769/92) and decisions having taken the opposite view (T 1177/97 and T 172/03) is cited as justifying the question.
