The following definitions shall apply under this Law:
— layout design (topography) means the three-dimensional arrangement, whatever
its expression, of elements, at least one of which is an active component, and all or
part of the interconnections of an integrated circuit, or such a three-dimensional
arrangement which is prepared for an integrated circuit intended to be manufactured;
— integrated circuit : a product, in final or intermediate form, of which at least one
element is an active component and some or all of whose interconnections are an
integral part of the body and/or surface of a piece of material that is intended to be
used electronically.
Article 90
Layout designs (topographies) for integrated circuits which are original insofar as
they are the fruit of the intellectual effort of their creators and which, at the time of
their creation, are not common for the creators of layout designs (topographies) and
manufacturers of integrated circuits, may be protected as provided for by this Law.
A layout design (topography) for integrated circuits, which consists of a combination
of elements or interconnections that are common, shall only be protected if the
combination, considered as a whole, meets the conditions referred to in the above
paragraph.
