"This decision certainly is not a landmark ruling setting out a major change in patent law for computer-implemented inventions in Germany. It's rather a continuation of a long line of thinking by the German courts. It is interesting because it is one of several cases in which the Federal Patent Court (Bundespatentgericht) has given applicants leave to appeal in order to clarify the law in Germany on computer-implemented patents. […] The court confirms previous case law that an invention is technical when the invention relates to the functioning of a computer system and allows the interworking of the computer system's elements. However, the court also confirms that this does not mean that all computer-implemented inventions are per se patentable. On the contrary, it emphasises that merely using a computer program does not confer patentability."
