Conveying information and Inventive Step BGH "Entsperrbild"

In the case X ZR 110/13 "Entsperrbild", the BGH had do decide on a patent relating to the unlocking of a mobile phone. The key feature is that an icon (unlock image - the small arrow 402 in the figure on the rhs) is moved together with the finger when executing the unlock gesture.

The Bundespatentgericht had disregarded the icon in the assessment of inventive step and judged that it did not contribute to the solution of a technical problem.

The BGH did not agree. According to the headnote, features relating to the conveying of information in a patent claim need to be subject to a special treatment:

1. Statements relating to the conveying of certain information contents and hence aim at having impact onto the human imagination or intellectual power are, as such, disregarded in the assessment of inventive step. Statements relating to information which shall be conveyed according to the technical teaching of the invention are apt to support the patentability in view of inventive step only insofar as they determine or at least influence the solution of a technical problem by technical means.
2. Information-related features of a patent claim are to be examined as to whether the information to be conveyed is, at the same time, an embodiment of a means for a technical solution, which must not already be indicated as such elsewhere in the patent claim. In such a case, the means for the technical solution as to be considered in the assessment of inventive step.

This decision is likely to be discussed in more detail later on.

When Does a Simulation Step Contribute to the Technical Character of a Method?

Oliver Randl has posted an interesting decision (T 1265/09) relating to an application claiming a method for generating schedules in a call-center. The method basically determines staffing requirements split up in different skill group and "adapts" the settings iteratively as a function of the result of a call-handling simulation.

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.

 

BGH Webseitenanzeige X ZR 121/09 - Technicity

The German Federal Supreme Court (BGH) has now issued a new decision on an alleged computer implemented invention.

The patent was directed to a method including a "displayable representation" showing the sequence of web-pages visited by a registered user on an information site.

The fact that the claim did not explicitly mention that the method is implemented using servers, clients and other technical devices was not considered harmful by the BGH because it was considered self-evident ("offenkundig") for the skilled person that the execution of the claimed method required the use of computers in a network such that the method was of technical nature. This follows the line of argument started in the decision "dynamische Dokumentengenterierung", according to which "a method consisting of the direct interaction between elements of a data processing system – a server and a client for dynamically generating structured documents in the case under dispute – has technical character irrespective of whether it is defined by technical features or not."

The BGH stresses that the question whether or not the method is excluded from patentability as a computer program "as such" needs an independent analysis of the additional requirement that the claim comprises instructions serving the solution of a specific technical problem with technical means.

Finally, the method was considered a "computer program as such" despite of being technical. The reason is that the hurdle of headnote 2 of dynamische Dokumentengenterierung was not taken. The latter requires that the method/the computer program is either "determined by technical features outside the computer or that the program accounts for the technical restrictions of the computer".
