What is INVENTION?
Thomas Edison (1847 – 1931) Edison filed over 1,000 patents. He developed and innovated a wide range of products from the electric light bulb to the phonograph and motion picture camera.
Alexander Bell (1847 – 1922) Credited with inventing the first practical telephone. Also worked on optical telecommunications, aeronautics and hydrofoils.
Alfred Nobel (1833 – 1896) Swedish chemist, engineer, innovator, and armaments manufacturer. Nobel held 350 different patents, dynamite being the most famous. His fortune was used posthumously to institute the Nobel Prizes.
An invention is a unique or novel device, method, composition or process. The invention process is a process within an overall engineering and product development process. It may be an improvement upon a machine or product, or a new process for creating an object or a result. An invention that achieves a completely unique function or result may be a radical breakthrough. Such works are novel and not obvious to others skilled in the same field.
