It was noted by the Court of Appeal in Aerotel and Macrossan that using the reasoning of most of the EPO case law (such as T 258/03 – Hitachi) would result in the same final conclusion as the "contribution" approach. However, the reasoning in a particular Microsoft case was held up as being flawed. The UKPO have also expressed the opinion that the end result would normally be the same. This is disputed by groups such as the Foundation for a Free Information Infrastructure who consider that the EPO is consistently granting patents that would be refused by the Courts in the UK and elsewhere in Europe.[http://press.ffii.org/Press_releases/Software_Industry_prepares_for_key_UK_patent_ruling_this_Friday
