This book discusses the global issue on software patents in the very simple manner. Traditionally, patents for computer -related inventions were rejected by patent offices. It was thought that computer programs were more like books (“literary works”) than other technological subject matter, such as automobiles, manufacturing machines and chemical compounds, and therefore should be protected by copyright. As we know that copyright only protects the expression and not the underlying concepts in software related inventions, and patent protection is potentially much broader. However, as the computer age progressed, computers and software took on an increasingly central role. Today, computers and computer software are at the forefront of technology. Although Patent Law has been slow to adapt, there have been rapid advances in the law in this area recently. Different countries and regional offices have different standards for granting patents, particularly for software or computer-implemented inventions.
