The EPO Board of Appeal refers to the decosion T 1227/05 in an attempt to define necessary conditions to be met by a simulation step in a method to contribute to the technical character of the method.
The board derives from T 1227/05 that:
The board held that beyond its implementation, a procedural step may contribute to the technical character of a method only to the extent that it serves a technical purpose of the method and, further, it held that a simulation of a circuit subject to 1/f noise constitutes an adequately defined technical purpose for a computer-implemented method, provided that the method is functionally limited to that technical purpose (Reasons, [3.1]). The claimed methods were held to meet these conditions because, firstly, they concerned an adequately defined class of technical items, and, secondly, the stated purpose, ..., was established in the further steps of the claimed methods, .... thereby functionally limiting the claims to the simulation of a noise-affected circuit (Reasons, [3.1.1-2] of T 1227/05, emphasis added).The Board further notes that these conditions are necessary but does not sufficient.
In the case at issue, the conditions were not found to be met
"since, in connection with the call handling simulation referred to in claim 1, the telephone call center and, in particular, its performance, are not further specified in the claim and, further, the claimed method does not define the further steps which actually result in the stated purpose, i.e. the call handling simulation." ([1.13] last par.)In other words - even if a call-center network is a technical system the simulation of which could be considered a technical task, the claim should cleraly define its technical features determining its performance and give details on how this is simulated.
At first sight, this appears to be somewhat narrower than the broader (and often-cited) statement in T1227/05:
"To that extent, specific technical applications of computer-implemented simulation methods are themselves to be regarded as modern technical methods which form an essential part of the fabrication process and precede actual production, mostly as an intermediate step. In view of this development it must be assumed that the outlay for implementing a technical product will increasingly shift to the numerical simulation phase, while final implementation of the simulation result in the actual manufacture of the product will entail no or only comparatively little extra innovation effort. In that light, such simulation methods cannot be denied a technical effect merely on the ground that they do not yet incorporate the physical end product (in effect the German Federal Court of Justice ruled in the same way in its decision of 13 December 1999, X ZB 11/98 - Logikverifikation; Reasons II.4(h))."However, the board appears to put emphasis on the words "specific" and "technical" in the first line of the above quote.
