Headnote:
A person who is detecting and replacing linguistic expressions
which exceed a predetermined understandability level in a list of
linguistic expressions using only his skill and judgment is performing
mental acts within the meaning of Article 52(2)© EPC. Accordingly,
schemes, rules and methods used in performing them are not inventions
within the meaning of Article 52(1) EPC.
Since according to Article 52(3) EPC patentability is excluded only
to the extent to which the patent application relates to subject-matter
or activities summarised in Article 52(2) as such, it appears to be the
intention of the EPC to permit patenting in those cases in which the
invention involves some contribution to the art in a field not excluded
from patentability.
The use of technical means for carrying out a method for performing
mental acts, partly or entirely without human intervention, may, having
regard to Article 52(3) EPC, render such a method a technical process or
method and therefore an invention within the meaning of Article 52(1) EPC.
However, if the technical implementation of such a method is obvious
to a person skilled in the technical art, once the steps of the method
for performing the mental acts have been defined, so that there is no
inventive contribution in a field not excluded from patentability under
Article 52(2)© EPC, such method does not involve an inventive step
within the meaning of Article 56 EPC.
If a claim for an apparatus (here: a text processing system) for
carrying out a method does not specify any technical features beyond
those already comprised in a claim pertaining to said method and
furthermore does not define the apparatus in terms of its physical
structure, but only in functional terms corresponding to the steps of
said method, the claimed apparatus does not contribute anything more to
the art than the method, in spite of the fact that the claim is
formulated in a different category. In such a case, if the method is
excluded from patentability, so is the apparatus.
The Board introduces the requirement for technical means in order to prevent the claim from being directed at unpatentable subject-matter, such as a procedure comprising mental steps. Although the claimed procedure could possible be performed by technical means, it was not limited to technical means.
