The title is confusing because they talk about "layout" and "topologies" but it is just actually lithography masks that are protected by this treaty: > (ii) 'layout-design (topography)' means the three-dimensional disposition, however expressed, of the elements, at least one of which is an active element, and of some or all of the interconnections of an integrated circuit, or such a three-dimensional disposition prepared for an integrated circuit intended for manufacture ...
