Semiconductor Layout Designs

In one line

The Semiconductor Integrated Circuits Layout-Design Act protects the arrangement of elements on a chip, which is neither a program nor a design nor an invention, and which nothing else protects.

In the wording a student can write in an exam: the Semiconductor Integrated Circuits Layout-Design Act, 2000 gives the registered proprietor of an original layout-design of a semiconductor integrated circuit the exclusive right to its use for ten years, defines a layout-design in section 2(h) as a layout of transistors and other circuitry elements including lead wires connecting them and expressed in any manner in a semiconductor integrated circuit, requires originality and the absence of prior commercial exploitation under section 7, and makes reproduction, importation, sale or distribution for commercial purposes an infringement under section 18, subject to substantial exceptions for scientific evaluation, reverse engineering and independent creation.

Why chips needed their own statute

Because nothing else fitted, and this is a rare case where the gap was real rather than argued.

Not copyright. A layout is a functional arrangement of circuit elements. It is not a literary or artistic work; its value is what it does, and every choice in it is dictated by electrical constraints.

Not patent. The layout is not an invention; it is one physical implementation of a circuit that is often already known. It fails novelty and inventive step routinely.

Not designs. The Designs Act protects features of shape, configuration, pattern or ornament judged solely by the eye, and expressly excludes anything that is a mode or principle of construction. A chip layout is never judged by the eye and is nothing but a principle of construction.

And the copying was trivially easy. A finished chip can be photographed layer by layer and the layout reconstructed, so a design costing years and crores could be copied for the cost of the photography.

So a sui generis right was created internationally, in the Washington Treaty on Intellectual Property in Respect of Integrated Circuits of 1989, and then in the TRIPS Agreement, articles 35 to 38, which obliged members to protect layout-designs. India's Act of 2000 gives effect to that obligation.

What is protected

Section 2(h): "layout-design means a layout of transistors and other circuitry elements and includes lead wires connecting such elements and expressed in any manner in a semiconductor integrated circuit."

Section 2 also defines a semiconductor integrated circuit as a product having transistors and other circuitry elements inseparably formed on a semiconductor material or an insulating material or inside the semiconductor material and designed to perform an electronic circuitry function.

And section 2(e) defines commercial exploitation in relation to a layout-design as to sell, lease, offer or exhibit for sale or otherwise distribute the semiconductor integrated circuit for any commercial purpose.
