Patentable invention - technical features (no)
Catchwords:

The contribution made to the art by the only features which are novel against the citation cannot be regarded as technical. The dynamic modification of the external interfaces displayed by interactive communication of the user with the computer neither solves a technical problem nor changes the principal internal working of the computer nor has a technical effect. No contribution to the art outside the field of matters excluded from patentability can therefore be recognised.
