EPO decision T 769/92 (1995): Sohei file shuffling system
According to this landmark decision of the European Patent Office's Technical Board of Appeal of 1995, computer-implemented business methods are patentable. In the EPO's own words "An invention comprising functional features implemented by software is not excluded from patentability under Art 52(2"(c) if technical considerations lend a technical nature to the invention in that they imply a problem to be solved by implicit technical features. So an accounting system can be technical if it has technical features (in this case, shuffling of files).)
