"The European Patent Convention (EPC), Article 52, paragraph 2, excludes from patentability, in particular
1. discoveries, scientific theories and mathematical methods;
2. aesthetic creations;
3. schemes, rules and methods for performing mental acts, playing games or doing business, and programs for computers;
4. presentations of information."
I believe the patent in question falls under 4, 3 and perhaps 2.
Unlike prior art, which often needs to be proven in court, disallowing software patents as a class means that this patent simply would not get issued in EU.
