The document discusses the differences between invention and innovation. Invention refers to creating something entirely new, while innovation is improving or contributing significantly to something that already exists. For example, Thomas Edison was an inventor who created new things, while Steve Jobs was an innovator who improved existing technologies. The document provides examples of how innovation at Apple transformed mobile phones and other technologies through new designs and user interfaces. While innovation builds on existing inventions, protecting inventions is important to allow inventors to profit from their work and license it to others. Overall, both invention and innovation are important for technological progress, even if innovation does not always require wholly new inventions.
